3 1. RISK ASSESSMENTS, METHOD STATEMENTS & NOTIFICATIONS 1.1 Policy Prior to undertaking any asbestos removal works a risk assessment and plan of works will be developed by a competent named member of the management team, the purpose of these documents is to assess the proposed works, identify the risk associated with the works (further to the asbestos), outline the method of work and detail any PPE/RPE required. All such documents will be site specific and be available onsite throughout the duration of the works; the document will be used to brief the operative s undertaking the works. Amendments (minor) to such documents will be permitted to be completed by the designated site supervisor; these will be recorded onsite and communicated to all site staff. Major changes will be completed by management and the enforcing authority/ client duly informed. 1.2 Risk Assessment and Method Statement Content The content of the risk assessment and method statement shall allow the onsite staff to complete their works; the content of the documents will follow the company s standard template and will meet the requirements set out in the regulations / guidance notes. An overview of the contents for the documents is contained below: Details of the Contract (including but not exhaustive): The name and address of whom we are contracted by The names, job titles and contact numbers of all relevant parties The dates when the works will be completed and the hours of work The enforcing authority details CDM details The analytical presence (include company, type of monitoring) Scope of work (including but not exhaustive): Details of survey Description of Work Details of Asbestos materials (type, form, size, condition etc) Site access, fire risk and other hazards associated with works (e.g., work at height) Control Measures (including but not exhaustive): Expected exposure levels Steps taken to reduce exposure Site diagram Enclosure dimensions, including air changes, NPU type Type of RPE to be used Smoke testing and monitoring arrangements Method of Work (including but not exhaustive): Specific working method Wetting system to be used Tools required Additional risks & controls adopted

4 Additional Requirements (including but not exhaustive): Type of decontamination, location / type of DCU Transit route Welfare Facilities Emergency arrangements (including local A&E) Waste disposal arrangement including quantity of waste and type of container 1.3 Nominated Individuals responsible for preparing the method statement and carrying out the risk assessments The Health & Safety Manager / Contracts Manager(s) at Active Environmental are responsible for preparing method statements and ASB5/ ASB NNLW1 Notifications including Site Location plans. They will carry out the appropriate risk assessments on the initial site visit to determine the safest method of work. To fulfil these roles as a competent person the individual must have: Adequate knowledge, training and experience of the risks associated with asbestos Understand how the activity will affect the asbestos Know the precaution to be taken to minimise exposure Understand the requirements of legislative controls Be able to assess non-asbestos risks On sites where there are multiple generic areas of similar ACM s method statements will contain site specific information for the initial asbestos works enclosures. Additional Site location diagrams will be generated and completed by the Site supervisor for each additional generic area on site. 1.4 In-house Quality Control for checking the method statement We at Active Environmental will ensure that each method statement is cross-referenced with the Health & Safety method Statement aide memoir (as issued by the Asbestos Liaison Group 2/03). All method statements will be reviewed by another member of the management team (as detailed above) and signed off prior to issue. 1.5 Notifications All works with ACMs will be notified to the relevant enforcing authority in (where applicable) in accordance with The Control of Asbestos Regulations The following works do not require notification: (a) The exposure to asbestos of employees is sporadic and of low intensity; and (b) It is clear from the risk assessment that the exposure to asbestos of any employee will not exceed the control limit; and (c) The work involves (i) Short, non-continuous maintenance activities in which only non-friable materials are handled, or

5 (ii) Removal without deterioration of non-degraded materials in which the asbestos fibres are firmly linked in a matrix, or (iii) Encapsulation or sealing of asbestos-containing materials which are in good condition, or (iv) Air monitoring and control, and the collection and analysis of samples to ascertain whether a specific material contains asbestos. Where the above exemptions for notification are not applicable, notifiable asbestos works can be summarised within the following categories: i) Licensable Notifiable Works Notifications to be made in writing to the HSE (ASB5 notification form to be submitted to the HSE) a minimum of 14 days prior to commencing works onsite. ii) Notifiable Non Licensed Works Notifications to be made in writing to the HSE via the online ASB NNLW1 form via a computer or smartphone prior to the commencement of works (no minimum notification period exists for works of this nature). The Control of Asbestos Regulation s 2012 and HSE;s guidance will be followed to determine if proposed asbestos works are applicable to either of the above notifiable categories of work. 2.0 Site management We at Active Environmental will ensure that for licensable works there will always be a supervisor on site to direct operations during key stages. Key stages can be determined as: Planning Set up Smoke test Asbestos removal Cleaning & 4-stage clearance In almost all circumstances, this will mean a continuous presence on site. If a supervisor is required to leave site (i.e. for short durations) he/ she will appoint an operative to act in his/ her absence. For non-licensable works each job will be assessed and where possible a suitably trained asbestos supervisor will attend site to oversee works. For jobs of a more minor nature and of less complexity a suitably trained/ competent operative will be assigned to supervise/ complete works on site. We at Active Environmental will endeavour to ensure a Supervisor will be on site at all times, as a minimum the supervisor will be required onsite at key times (e.g. smoke testing, 4 stage assessment). If a supervisor is required to leave site he will appoint an operative to act in his absence. The Supervisor will return to the site prior to the end of the shift to carry out his/her final daily checks.

6 3.0 Site Audits A Management representative is responsible for ensuring that internal audits are completed to the agreed programme, and for ensuring that any corrective actions agreed following such audits are completed in the agreed timescale. Internal audits are undertaken in accordance with the Internal Audit Schedule. The auditing of supervisors shall be completed to ensure that at least 4no are completed in any 12 month period, the schedule will be increased where previous audits have indicated problems in site management. In addition the supervisor will be subject to ARCA audits, these audits will be rotated through the company s supervisors to ensure the same standards are applied across the board. The results of all audits will be circulated to the management team and the supervisor in writing. Members of staff do not audit areas for which they have responsibility. Those responsible for areas to be audited will be advised prior to the audit to ensure that they are available during the audit. Should no discrepancies be found in an audit, the auditor will indicate the audit as CLOSED OFF on the audit schedule. 4.0 ANNUAL REVIEWS The company procedure manual is a controlled document and will be issued subject to management control. The document represents the procedures to which all company personnel will undertake asbestos removal operations. The document will be reviewed on an annual basis to ensure the procedures laid down within are relevant. Reviews will compare the document against legislative requirement, company operations, nature of works being undertaken and audit findings. Where any changes are made to legislation or internal/ external audits identify a failing in the procedures laid down herein the document will be reviewed and any corrective action taken (as necessary) EXPOSURE ESTIMATES We at Active Environmental will use data gathered from personal monitoring and the examination of publicly available data (i.e. HSE guidance publications) to estimate expected exposure levels during works and draw up appropriate working methods. Active Environmental will aim to reduce exposure the lowest possible level through controlled removal techniques, the stated protection factor of the RPE will also be accounted for, with the aim to ensure that personal exposure does not exceed the control limit of 0.1 f/cm 3 over a 4 hour period.

7 6.0. SITE RECORDS 6.1 Validating Staff Records We at Active Environmental validate all our staff records (including medical, training and face fit certificates) by contacting the issuing company/office. We will also contact an applicant s previous employer to confirm that they have the relevant experience for the position that they are applying for, and any further information that may be of relevance (i.e. time keeping and attendance ratios). Where temporary site staff are supplied by an HSE licensed asbestos labour supply agency (asbestos removal operatives) Active Environmental will validate records (as identified above), copies of temporary site staff records will be held at the Active Environmental offices. 6.2 Validation of Site Records We at Active Environmental validate all our site records by having all personnel records and plant DOP test certificates & electrical test certificates, stamped and dated as CHECKED. The certificates are authorised by the company s office manager. 6.3 Method Statement Compliancy On the initial day of the site set up, the contracts manager (where possible) will accompany the designated site supervisor to site. They will walk the site together and note any discrepancies that have become apparent since the initial site visit. These discrepancies will be immediately transferred on to a Method Statement Variation Sheet within the site data pack. Supervisors and operatives are to read the method statement and sign the method statement briefing register. Where a significant amendment to the work is required or further acm s have been uncovered Active Environmental management will be required to provide appropriate amendments (i.e. amended ASB5)/ re-notify works to the HSE (i.e. new ASB5) as per the HSE s guidance. (as necessary). 7.0 TRAINING & HEALTH RECORDS/ MEDICAL SURVEILLANCE 7.1 Staff Selection Active Environmental will endeavour to recruit staff that are suitably competent (e.g. have the skills, knowledge, awareness, training and expertise) to fulfil the role for which they will be employed. Prior to employment all staff will be interviewed by management and their personal paperwork checked and validated by contacting the issuing body/company.

8 Active Environmental will also contact an applicant s previous employer to confirm that they have the relevant experience for the position that they are applying for, and any further information that may be of relevance (i.e. time keeping and attendance records). Where persons new to the industry are employed, the full nature and hazards associated with the work shall be fully explained at the time of interview. The interviewer shall also make all reasonable enquiries to assure himself of the suitability of the candidate. 7.2 Staff Training We at Active Environmental will provide adequate training for management, supervision and operatives. A training matrix detailing the standard requirements (both statutory and company) of employees at all levels will be used to assess all staff and identify training needs of new and existing employees. All asbestos management/ supervisor/ operative training will be undertaken by an HSE recognised training provider. Asbestos management/ supervision/ operative training will be as a minimum refreshed annually or as determined by training needs analysis. Further training will be provided to Active Environmental management/ supervision/ operatives as required including but not limited to: Manual Handling Work at Height Confined Space Entry PASMA IPAF Abrasive Wheels Quill Dustless Blasting 1st Aid Site Supervisor Safety Training Scheme (SSSTS). Additional training will also be made available following a request from an employee; this training will be provided at the discretion of management (in the event that training is not provided the reasoning will be documented) New Employees Successful applicants (dependent on role) will work under the supervision of an existing employee in order to gauge their competence, assess suitability for the role and identify further training requirements Prior to commencing their employment the Management will ensure that all employees attend an induction training session to receive orientation and instruction relating to the company (including its Health and Safety policy and procedures), the staff (who is responsible for what and how they can be contacted), the workplace (hazards present, control measures and emergency procedures) and equipment used (where its located, how it is stored, the correct use of and maintenance/testing requirements).

9 Active Environmental management will ensure that the recipients of the information understand what is expected of them, and that they are given information about the following: a) The Health and Safety at Work Act 1974 b) The Company s Policy for Health, Safety and Welfare. c) Fire Procedures (including the location and use of extinguishers as appropriate). d) First Aid - names and locations of first-aiders, introduction to them, and position of first aid boxes and rules for their use. e) Use and availability of protective clothing and equipment. f) General hazards in and around their work area. g) Specific hazards in and around their work area, to include a copy of the risk assessment / method statements for the task(s) that they are being employed to carry out. h) Procedures for reporting accidents, injuries and property damage. i) Safe systems of work. j) Welfare - locations of kitchens, toilets, showers and any other welfare matters whether at the office or on-site. Contract Managers/Supervisors are required by this policy to review with all new employees, any hazards and specific safety rules applicable to the work before putting him/her to work. Once employed by Active Environmental all staff will have access to all relevant HSE publications, personal copies will also be available on request. All new employees shall be subject to a minimum of three months trial and assessment prior to confirmation of full time employment. All staff will be employed in accordance with the Active Environmental employment contract and employees will be contracted with due regard given to the company s equal opportunities policy Existing Employees Active Environmental will use regular toolbox talks to ensure that all operatives are fully aware of the hazards encountered during their works and the control measures (outlining safe systems of work) in place for their (and others) protection. Toolbox talks will be used to provide information on new systems of works and detail additional training requirements (e.g. due to changes in legislation). Toolbox talks enable operatives to provide feedback regarding their experiences of onsite works and any improvements/additions to enable them to complete their works safely. Annual reviews will be carried out by Active Environmental management with all employees, the annual review process will seek to provide Active Environmental management with feedback as to operatives experiences on site and to identify any areas of improvement/ additions that could be made in regard to health and safety. As part of the review process Active Environmental management will discuss personal performance based upon feedback received from site audits and supervisor feedback. Additional training needs (if any) will identify and discussed to enable further training to be arranged (as required).

10 7.3 Training Records Up to date records of training will be kept for all employees, refresher training will be instigated as and when required (e.g. employees to undergo refresher training prior to expiry of existing certification). Copies of all training records (for both Active Environmental employees and operatives provided by licensed asbestos labour supply agencies) will be held by the company for the duration of the term of employment, additional copies of training certificates will be provided to site supervisor s/ operatives, these are to be carried on site at all times. All staff training records will be validated after cross-referencing checks have been completed (by Active Environmental management), training records to be stamped as verified and initialled. 7.4 Health Records/ Medical Surveillance Licensable Work With ACM s Medical Surveillance Active Environmental will ensure that all personnel employed by them to undertake work with licensable acm s are subject to medical surveillance by a trained and competent medical practitioner (in line with HSE guidelines) at least once every two years or such shorter time as the relevant doctor may require (as determined by a doctor for individual employees) Non Licensable Work With ACM s Medical Surveillance Active Environmental will ensure that from 1st May 2015 all personnel employed to undertake work with non licensable acm s are subject to medical surveillance by a trained and competent medical practitioner (in line with HSE guidelines) at least once every three years or such shorter time as the relevant doctor may require (as determined by a doctor for individual employees). Where employees carry out work with both licensable and non licensable acm s medical surveillance will be carried out in accordance with CSP Health Surveillance Record Keeping Copies of all medical records will be held by the company for a minimum period of four years from the date on which it was issued. Additional copies of medical certificates will be provided to site supervisors/ operatives; these are to be carried on site at all times. All staff medical records to be stamped as verified and initialled.

11 8.0. RESPIRATORY PROTECTION & PERSONAL PROTECTIVE EQUIPMENT (PPE) Respiratory Protection 8.1 Selection of Respiratory Protection Equipment (RPE) We at Active Environmental select our RPE dependent on the risk factor presented by the type of work being undertaken and any knowledge of expected airborne fibre levels. RPE is not absolute in its protection and should be employed alongside general good working practices to assist in controlling the potential exposure of operatives to asbestos fibres. RPE will be provided by the company to all personnel employed in asbestos removal operations, when selecting the RPE to be supplied the following must be adhered to: RPE will be adequate and provide the wearer with suitable protection (taking into the accounts the works to be completed and the expected exposure levels encountered) Be suitable for the intended use (e.g. what is the assigned protection factor) Be CE Marked Be selected, used and maintained by trained persons Be correctly stored, maintained and tested Have adequate records kept of selection, maintenance and testing Compatibility with other items of PPE required for works How comfortable the RPE is to wear and the facial characteristics of each wearer Types of RPE We at Active Environmental will seek to ensure that RPE selected for use on site conforms to the following (or equivalent) type: Full Face: or or or or Half Mask: or or or Sabre Phantom Respirators Sabre Phantom Vision Protector Vision Gemini Kemira Gemini R40 Ori-Nasal. Moldex twin filter. Sunstrom SR100 Wilson The selection of the type of Respirator will be subject to each individual s requirements, ensuring the mask is suitable for task and comfortably fits the wearer. In addition RPE shall be selected that complements other PPE required for works.

12 8.2 Maintenance of RPE RPE will be inspected and maintained in accordance with legislative and the manufacturers guidance. As detailed below each individual operative will conduct daily inspections of their RPE, nominated site supervisors will be additionally trained ( by the manufacturer/ supplier) in the correct procedure for assessing the RPE. Supervisors will conduct checks on a monthly basis of all site operatives RPE Daily Checks Operatives will carry out daily checks of personal RPE. Theses checks are to include: 1. That a satisfactory flow rate is generated by the motor 2. The visor is in good condition 3. Battery is working 4. Charger is working 5. That the mask condition and seals are good 6. Power unit (where applicable) is working 7. Hose (where applicable) is in good condition 8. Belt is in good condition 9. Valves are in good condition and working Records of daily checks are to be maintained by individual operatives and stored to the site file. All repairs and maintenance should be fully recorded. At the completion of site works all records are to be returned to the head office for storage Monthly Checks All RPE is to be checked on a monthly basis by a nominated competent person. The checks are to cover those areas detailed in section Records of all monthly checks, repairs and maintenance will be kept at head office Six Monthly Checks Power assisted RPE (e.g. full face masks) will be subject to independent assessment on a six monthly basis; these checks will test the effectiveness of the mask performance. The testing company will issue conformity certificates, copies of which will be held in the company offices and also by the operative. These checks will be required after a mask has undergone repairs that may affect the effective seal or distort the mask (e.g. replacement of visor) Face Fit Tests We at Active Environmental will carry out Face Fit tests if a new employee starts and does not have the relevant test for the masks that we issue, we will also undertake face fit tests to all employees undertaking asbestos works as determined by individual face fit certification and as a minimum on a bi-annual basis.

13 In addition a repeat fit test should be conducted where the wearer: Is changing to a different model of RPE or different sized face mask; Loses or gains weight; Undergoes any substantial dental work; Develops any facial changes (scars, moles etc.) around the face seal area 8.3 Standards and Limitations for Full Faced Powered RPE The chosen respirator will be manufactured to EN 147 and fitted with a P3 type filter. The protection factor assigned for this type of respirator is 40. The detected fibre concentration within an enclosure where a full face respirator is to be worn will be maintained at a level of less than 4 fibres per ml air sampled such that the fibre concentration in the face piece is maintained below 0.1 f/ml ( The control limit as defined by Control of Asbestos Regulation 2012 for asbestos fibres sampled in air averaged over a 4 hour period) Operations for which a Full Face Powered Respirator should be selected Unless stated otherwise, full-face power assisted Respiratory Protective Equipment (RPE) will be used when removing asbestos within enclosures. 8.4 Standards and Limitations for Half Mask RPE The chosen half mask will be manufactured to EN 143 and fitted with a P3 type filter. The protection factor assigned for this type of respirator is 20. The detected fibre concentration within a work area where a half mask respirator is to be worn will be maintained at a level of less than 2 fibres per ml air sampled such that the fibre concentration in the face piece is maintained below 0.1 f/ml ( The control limit as defined by Control of Asbestos Regulation 2012 for asbestos fibres sampled in air averaged over a 4 hour period) Operations for which a Half Mask Respirator should be selected This type of respirator will only be used during preparatory site works, when handling bagged or wrapped asbestos waste (external to an enclosure), when removing asbestos cement products in well-ventilated areas or when works of a minor nature are to be undertaken and the expected fibre release during these works is <1.0 f/ml.

14 Personal Protective Equipment (PPE) 8.5 Selection of Personal Protective Equipment We at Active Environmental select our PPE to provide suitable protection against contamination (i.e. Asbestos fibres and dust) that may be generated during works. PPE is not absolute in its protection and should be employed alongside general good working practices to assist in controlling the potential exposure, spread and release of asbestos fibres. 8.6 Types of PPE Coveralls / Overalls The coveralls supplied by Active Environmental will be of the disposable type and made of non-static material. They will zip fasten, have elasticised hoods (which will always be worn over the RPE straps), cuffs and ankles, and no pockets. All coveralls will be colour coded to indicate their precise use. EXAMPLE COLOUR CODES A - WHITE Used for enclosure preparation/ for the transit of waste to van / skip. Semi enclosed works in wellventilated areas. B - RED Only for use in live/ contaminated enclosures. C - BLUE Used for transiting between the working enclosure and the hygiene (or decontamination) unit. Coveralls will be of type 5 category 3 standard Boots Whilst working in a contaminated enclosure all operatives will wear steel toecap boots (including midsole protection) with the leggings of the coveralls pulled over the top of the boots (and not tucked in). Boots are to be decontaminated inside and outside at the end of each working shift, bagged and left in the enclosure. On completion of removal works they will once again be decontaminated inside and out, bagged and removed from the works area to be only reused in similar work environments Gloves Gloves will be supplied to protect the operatives skin from any irritation and to provide a firmer grip when working in wet conditions. The coveralls cuffs will be worn over the gloves.

15 8.6.4 Safety Helmets Safety Helmets will comply with BS2826 and will be issued to each operative in accordance with the Construction (Head Protection) Regulations DECONTAMINATION and TRANSIT PROCEDURES 9.1 Selection of suitable Decontamination and Transit Procedures We at Active Environmental will select decontamination and transit procedures dependent on the works that are being carried out and to comply with current legislative requirements. 9.2 Selection of a suitable Decontamination Unit (DCU) Where a DCU is considered necessary it will comply with the requirements as set out in Appendix 8.1 Minimum Design Criteria for Asbestos Hygiene Units (HSG 247) Supervisors should ensure that the DCU conforms to the following minimum requirements: a) The DCU is clean b) The DCU should have a minimum of one showerhead per four operatives present on site. c) An earth rod should be supplied with the unit (if applicable/ specified by the individual manufacturer). d) A mirror should be positioned within the clean end of the DCU e) Soap, shampoo, nail brushes and towels should be supplied (available). f) Doors should be self closing. g) The shower should work and provide hot water. h) Adequate storage should be available for clothes and equipment. i) The unit shall have sufficient heating and lighting j) Waste water shall be filtered prior to disposal k) The unit shall incorporate an NPU l) Provide 240 volt sockets Positioning of the DCU Wherever possible the DCU should be connected directly to the enclosure. Where it is not possible to connect the DCU to the enclosure it will be sited as close to the works area as reasonably practicable and full transit procedures will be utilised. The position of the DCU and transit routes will be identified to the Plan of Work Establishment of the DCU Supervisors should ensure that DCUs: a) Are sited appropriately. b) Are connected to water and power supplies before the commencement of any site or preparatory works. c) Are earthed (where applicable/ specified by individual manufacturers). d) Are stabilised and level. e) Have foot stalls available for entry and exit. f) Have appropriate warning notices posted to entry and exit points g) Have a waste bag supplied to the dirty end for the disposal of contaminated items.

16 h) Contain notices detailing emergency procedures and general operating instructions (boiler etc). i) Are cleaned daily and maintained in good condition. j) Have a clearance air test certificate displayed to the clean end (provided from previous works) The provision of a DCU A DCU will be provided by Active Environmental where deemed from the Risk assessment / Method statement that it is required. DCUs will always be provided for licensable (notified) works, where works are non-licensable the assessment will take into account the following factors: 1. Type of material works being completed on 2. Quantity of material present / duration of works 3. Working environment 4. Method of works 5. Occupation of site / others onsite Air testing of DCUs Where a DCU has been used onsite for licensed asbestos removal works, prior to being removed from site at the end of the contract it will undergo an inspection and clearance test by a UKAS accredited analyst In addition where a DCU is used on an ongoing contract it will have regular (weekly) reassurance air testing. Copies of clearance air testing are to be stored in the clean end of the DCU. Where a DCU is required to be removed from site (due to security reasons) at the end of each shift, the DCU MUST be locked and removed from site, it will remain locked and will be considered to be contaminated, at the end of the contract the unit will be tested. 9.3 Defined Decontamination Procedures Four types of decontamination procedure have been identified and formalised for Active Environmental operatives carrying out works with asbestos containing materials: a) Full Decontamination b) Full Decontamination (transit) c) Full Decontamination (semi enclosed) d) Decontamination (Minor Works) Full Decontamination A Decontamination Unit (DCU) (see section 8.2) will be required on site and will be attached to the works enclosure by means of a one stage dirty airlock and suitably constructed vented tunnel (walkway) linking the airlock to the dirty end of the DCU.

17 Operatives will enter the enclosure in the following sequence Take RPE/PPE/ toiletries into DCU via clean end door Inspect and Check RPE Put on clean PPE. Put on RPE using mirror. Carry out fit - check Pass through shower area (without showering and leaving toiletries) into the dirty end Leave DCU. Go through interim space and airlock into enclosure

18 Operatives will exit the enclosure and decontaminate in the following sequence Leave enclosure and enter the airlock Vacuum all visible dust and fibres from PPE, RPE and footwear. Brush footwear in footbath. Sponge or wipe RPE Enter dirty end of DCU. Take off all footwear, coveralls and underwear worn in the enclosure. Footwear should be cleaned and stored in sealed clear plastic bags. Disposable coveralls and other items should be placed in red asbestos waste bags and sealed at the neck for disposal as asbestos waste. Do not remove RPE Move to shower area with respirator on. Shower and use a sponge to clean RPE without allowing water on to filter ports Once RPE has been cleaned, remove it and shower yourself thoroughly. Remove used filters and place in waste bag for disposal Start drying off. Place towel in bag for disposal or laundering Pass through into clean end and complete drying with a different towel(s). Dress Leave DCU via clean end external door

19 9.3.2 Full Decontamination (Transit) A Decontamination Unit (DCU) (see section 8.2) will be required on site and will be sited as close to the work area as reasonably practicable, but will not be directly attached to the enclosure. Operatives will transit to and from the enclosure along designated transit routes. The transit routes will be clearly marked by erecting transit route direction notices at appropriate points along the route. Operatives will transit to the enclosure in the following sequence Take RPE/PPE/toiletries into DCU via clean end door Inspect and check RPE Put on clean PPE. Put on RPE using mirror. Carry out fit-check Pass through shower area (without showering and leaving toiletries) into the dirty end. Dress in transit coveralls and footwear.

Remove used filters and place in waste bag for disposal Start drying off. Place towel in bag for disposal or laundering Pass through into clean end and complete drying with a different towel(s). Dress Leave DCU via clean end external door

21 9.3.3 Full Decontamination (Semi - Enclosed) A Decontamination Unit (DCU) (see section 8.2) will be required on site and will be sited as close to the work area as reasonably practicable. As works are of a semi - enclosed nature no enclosure will be erected. However the work area will be segregated by the use of barrier tape and polythene drapes ( courtesy sheeting, when specified to method statement). Operatives will transit to and from the enclosure along designated transit routes. The transit routes will be clearly marked by erecting transit route direction notices at appropriate points along the route. Decontamination procedures reflect the fact that airlocks will not be present to the works area. Operatives will transit to the work area in the following sequence Take RPE/PPE/toiletries into DCU via clean end door Inspect and check RPE Put on clean PPE. Put on RPE using mirror. Carry out fit-check Pass through shower area (without showering and leaving toiletries) into the dirty end. Dress in transit coveralls and footwear. Pass through door of dirty end and walk to work area via designated transit route. At the designated barrier to the work area remove transit coveralls and footwear; place in container / on hooks. Do not leave on the floor Pass Into the work area

22 Operatives will transit from the work area and decontaminate in the following sequence At the designated barrier to the work area vacuum visible dust and fibres from PPE / RPE and footwear (separate vac to be provided for decontamination purposes). Wash footwear in footbath. Sponge down or wipe RPE. Remove coveralls and place in waste bag. Exit work area. Put on transit overalls and transit footwear stored to external of work area. Walk to DCU via designated transit route Enter dirty end of DCU. Take off all footwear, coveralls and underwear and place in storage or disposal bags. Transit footwear should be cleaned and stored. Disposable coveralls and other items should be placed in red asbestos waste bags and sealed at the neck for disposal as asbestos waste. Do not remove RPE Move to shower area with respirator on. Shower and use a sponge to clean RPE without allowing water on to filter ports Once RPE has been cleaned, remove it and shower yourself thoroughly. Remove used filters and place in waste bag for disposal Start drying off. Place towel in bag for disposal or laundering Pass through into clean end and complete drying with a different towel(s). Dress Leave DCU via clean end external door

23 9.3.4 Decontamination (Minor works) A Decontamination Unit (DCU) (see section 8.2) will not be required on site. As works are of a semi - enclosed nature no enclosure will be erected. However the work area will be segregated by the use of barrier tape and polythene drapes ( courtesy sheeting, when specified to method statement). Decontamination procedures reflect the fact that airlocks and a DCU will not be present to the works site. It is expected that these procedures will only be used for works of a very minor nature e.g. the removal of flash guards, small amounts of AC (<2.0m 2 ) removed intact, or bituminous / resinous products. Operatives will transit to the work area in the following sequence Inspect and check RPE Put on clean PPE. Put on RPE using mirror. Carry out fit-check Put on transit coveralls and walk to work area via designated transit route. At the designated barrier to the work area remove transit coveralls and footwear; place in container / on hooks. Do not leave on the floor Pass Into the work area Operatives will transit from the work area and decontaminate in the following sequence At the designated barrier to the work area vacuum visible dust and dirt from PPE / RPE and footwear (separate vac to be provided for decontamination purposes). Wipe footwear using dampened cloths. Sponge down or wipe RPE. Remove coveralls. Place all waste in waste bag. Exit work area. Wipe / clean hands and face / exposed areas. Clean and remove RPE

24 9.4 Decontamination of tools and equipment Hand tools We at Active Environmental use the following procedures for cleaning contaminated hand tools: a) All tools are washed in a bucket of soapy water and then dried using disposable paper towels. b) They are then placed into a clear Asbestos bag and the bag sealed with tape round the neck. c) They are then transferred via the designated transit route and stored to a safe, lockable area (e.g. in the back of the company vehicle). d) They will remain in the sealed bag until transferred to a further enclosure whereupon the bag can be opened and the tools re-used General plant We at Active Environmental use the following procedures for the decontamination of general plant (Vacuums and Negative Pressure Units): a) All pre-filters and vacuum cleaner bags will be removed and bagged as contaminated waste(this should be carried out as a part of the final clean to an enclosure). b) All pre-filters and vacuum cleaner bags will be replaced, transit plates and cups will be attached to the exhaust points on the Negative Pressure Units. c) Vacuum cleaner pipes will be washed in a bucket of soapy water, dried with paper towels and placed into clear Asbestos bags (double bagged) and sealed with tape for transportation purposes. d) All external casings will be Vacuumed and Tack-Ragged ready for transport Access equipment We at Active Environmental use the following procedures for cleaning access equipment on completion of works within an enclosure: a) Where work equipment is present within a live enclosure at the time of the visual inspection it should be subject to a full inspection by the attending analyst. b) All platforms will be vacuumed-off using an H - type vacuum. Care will be taken to ensure that all crevices are free of dust. c) All platforms, braces and cross beams will be washed with soapy water, dried and then Tack-Ragged. d) Ideally large pieces of access equipment should only be passed to the external on completion of a satisfactory clearance air test within an enclosure. Where this is not possible items will be cleaned with tack-rags as they are passed from the dirty end of an enclosure to the external.

25 9.4.4 Specialist equipment We at Active Environmental use the following procedures for cleaning specialist access equipment once the project is completed. a) Where work equipment is present within a live enclosure at the time of the visual inspection it should be subject to a full inspection by the attending analyst. b) All platforms will be vacuumed-off using an H - type vacuum. Care will be taken to ensure that all crevices are free of dust. c) All the arms, braces, hydraulic and electrical cables will be Tak-Ragged only (to ensure no water gets into the hydraulic and electrical components). d) Further cleaning may be carried out once advice has been sought from the supplier / manufacturer regarding correct cleaning processes Plant which cannot be suitably cleaned We at Active Environmental use the following procedures for the storage of plant which cannot be fully decontaminated following use within an Asbestos enclosure. a) Power tools which cannot be effectively decontaminated are cleaned as far as reasonably practicable using Tack-Rags. b) Tools are then placed in clear Asbestos waste bags which are sealed prior to removal from the enclosure. c) Bagged items are transported from the enclosure via designated transit routes to a safe, lockable area. d) Items will remain in the sealed bag until transferred to a further enclosure whereupon the bag can be opened and the tools re-used. e) Power tools which cannot be effectively decontaminated will carry an identity mark signifying that they are to be used within Asbestos enclosures only. 10. CONSTRUCTION of AIRLOCKS and ENCLOSURES 10.1 Site preparation The work area is to be segregated using red and white barrier tape and relevant warning signs Pre cleaning Pre-cleaning should be carried out when loose dirt or dust will prevent the erection and maintenance of a good enclosure or where debris or obstructions exist within an enclosure area that can be easily removed prior to the commencement of works and without disturbing any asbestos containing materials (ACMs).

26 Use of Enclosures Work on materials requiring a license to remove will generally require an enclosure to be formed; the enclosure will be required regardless of the nature of the works location or size of the premises. In certain circumstances an enclosure for licensable ACMs may not be required (as deemed by the RA), taking into account the risk and likely costs, these are summarised below: The level of risk is low, because the operations are of short duration and very small scale The location is extremely remote where the risk to operatives and others is low The work is at height and the forming of an enclosure is not practicable It is a situation where forming an effective seal on the structure Cleaning up minor contamination or external contamination Where a licensable contractor undertakes short duration works of a repetitive nature than an enclosure will be required. Works with non licensable products will not normally require an enclosure to be erected, however in some circumstances this will be necessary (e..g. in sensitive locations, dependent on removal methods etc) Positioning of the enclosure The enclosure should be constructed in the position identified to the method statement. Wherever possible the building form should be incorporated into the enclosure to provide natural boundaries. The enclosure should be as small as possible but large enough to contain the work and allow reasonable working space. Major variations to an enclosures design (in comparison to the method statement) should be noted to the on site method statement addendum sheet Construction of an enclosure Enclosures will be constructed using 1000 gauge polythene sheeting. Where additional support is required 50mm x 50mm wooden lengths will be used to form a frame. The frame will be nailed or screwed into a suitable structural feature where this is practicable. The polythene sheeting will be joined and sealed with adhesive glue and 75mm poly cloth tape. The polythene sheeting will be attached to the frame / building form using staples, adhesive glue and 75mm pcl tape. Staple points and seams will be sealed over with 75mm pcl tape. As far as is reasonably practicable the enclosure design should seek to exclude all non contaminated items and loose or friable surfaces. This may include: 1. Voids 2. Machinery 3. Light sockets / light fittings 4. Immovable fixtures and fittings 5. Walls 6. Floor coverings

27 These items (and others) should be sheeted out of enclosures whenever it is practicable to do so. Floor coverings should be protected with a double layer of 1000g polythene. Floor sheeting should be fully glued and sealed to the walls of the enclosure as well as being affixed to the floor. When items / structural features cannot be sheeted out of the enclosure they must be cleaned as a part of the works process. Windows should normally be fully covered and sealed with polythene sheeting or as a minimum frame edges sealed (particular attention should be made to window positions during smoke testing should only frame edges be sealed. Holes / pipe exit points / flue exit points etc will be sealed over using tape, glue and polythene or will be filled with expanding foam. Vision panels (600x300mm) should be inserted into the enclosure at positions to give as full a view of the work area as reasonably practicable. Where vision panels cannot give a clear view of the works area CCTV will be used to monitor works. A negative pressure unit(s) (NPU) should be attached to the enclosure at the position indicated for it on the method statement. The NPU will be of sufficient capacity to provide a minimum of ten air changes per hour. NPU capacities are as follows: 500 NPU 847 cubic meters per hour 1500 NPU 2542 cubic meters per hour 4000 NPU 6780 cubic meters per hour *Where additional flexible ducting is to be used (i.e. exhaust ducting/ roving head ducting) a deduction of 20% will applied to the npu capacity, reduced npu capacities will noted within the plan of work. Air / bag locks will be attached to the enclosure as specified within the method statement Airlock and Bag lock Construction The air / bag lock should be as big a possible to allow the necessary changing, cleaning and transfer activities for operatives and waste from the enclosure Where space permits a separate bag lock will need to be incorporated into the enclosure design. The air / bag lock system will consist of three chambers. Each chamber will be constructed using 1000 gauge polythene sheeting supported on a timber or metal framework. 75mm poly-cloth tape, staples and adhesive glue will be used to affix the sheeting to the frames and seal all of the edges. When practicable each air / bag lock chamber will be a minimum of 1.0m x 1.0m square and a minimum of 2 metres in height. Where insufficient room is provide for sitting the airlock / bag lock the dimension will be adapted to attempt to achieve the required dimensions of 1.0m x 1.0m x 2.0m. No air / bag lock will be less than 0.60m x 0.60m square. Where large items of waste are to be removed the bag lock will be constructed of a suitable size to allow ease of removal. The chambers will inter-connect via a straight vertical cut with reinforced, sealed edges. Access points between each air / bag lock stage will be protected by a 1000 gauge polythene flap.

28 Each flap will be positioned to the enclosure side of each chamber, will extend to rest between 25mm and 200mm from the base of the airlock (but never higher than the reinforced step / lip of the airlock entrance) and will be suitably weighted at the bottom. Air / bag lock flaps should be weighted to suitably restrict airflow through the enclosure and assist in the purging of contaminated air. Flaps should rest at an angle of C. 45 under full negative pressure. Wherever possible, the airlock system will be constructed directly on to the hygiene/decontamination unit. Air / bag locks will contain a vision panel (600x300mm) in the dirty stage Warning Notices Prohibition and mandatory signs will be situated on and around the enclosure and on the entrance (first stage) of the air / bag lock to prevent unauthorised access. Showing No access for unauthorised personnel Respiratory Equipment must be worn Safety overalls must be worn Danger Asbestos hazard 10.4 Negative Pressure Units (NPUs) As the sealing of asbestos enclosures cannot be guaranteed, Active Environmental will use NPUs to ensure all asbestos enclosures are placed under negative pressure to ensure that no asbestos fibres will escape the works area. NPUs will be provided in accordance with the BS8520 requirements and will hold valid DOP and PAT tests (completed on a 6 monthly basis). All NPUs will be fitted with a HEPA filter and will be monitored and maintained when in use. During all works within the enclosure the NPU will be active and will remain so for at least 1 hour following cessation of works within the enclosure after this point the enclosure can be sealed (e.g. air /bag locks sealed) and the NPUs turned off NPU Location To achieve the best airflow within an enclosure where possible the NPU will be sited opposite the air / bag lock position at the furthest point of the enclosure. The size and layout of the enclosure will affect the NPU location, enclosures designs will be considered to ensure dead spots do not occur and that airflow across the enclosures is maintained at the same level. The use of roving heads within enclosure to ensure adequate airflow to all work faces will be utilised, this will be of particular importance when NPUs are located close to one another. In addition designated air inlets will be incorporated into the enclosure (where required) to assist with airflow within the works enclosure. The location of air inlet positions will be documented within the plan of work. Air inlets will be formed using a pre filer complete with internal weighted flap.

29 NPUs will be normally sited outside of the enclosure (space permitting), with the pre filter accessible from the inside. Where NPUs have to be incorporated within the enclosure they will be sheeted out of the works area and sealed over using timber boarding NPUs will discharge to atmosphere / well ventilated areas, these use of flexible ducting is permissible to achieve this. Where the NPU discharges into an enclosed space air monitoring (leak / reassurance) will be required periodically throughout the contract Smoke testing On completion of the construction of a satisfactory enclosure (one that conforms to the standards set out to sections 9.2, 9.3 and 9.4) and prior to the commencement of asbestos removal works a smoke test will be carried out. The smoke test is designed to check the integrity of the enclosures construction. The site supervisor should visually inspect the construction of the enclosure prior to the smoke test. Any faults (visible holes, creased polythene) should be corrected immediately. The smoke test will be witnessed by the site supervisor and an independent party (where possible). The independent party could be: 1. The clients nominated representative 2. The analyst 3. The site manager Prior to smoke testing the supervisor should check that all relevant parties (e.g. the site manager) are aware that testing is due to commence and that smoke detectors and fire alarms are isolated within the enclosure area. When the supervisor is satisfied with the enclosures construction and the independent witness is in attendance the enclosure should be filled with smoke. The smoke should be generated from an 110v smoke machine. When filling the enclosure with smoke the smoke plume should be directed at seams and known weak spots (e.g. NPU or airlock attachment sites). The independent witness and supervisor should watch for smoke leaking to the external of the enclosure. Where leaks are detected they should be rectified (sealed) and re-tested. When the supervisor and independent witness are satisfied that there are no leaks from within the enclosure the NPU(s) should be turned on and the negative pressure checked (see section 9.3). If there is insufficient negative pressure further NPUs may need to be attached to the enclosure. If any adjustments are made to the enclosure between the completion of smoke testing and the commencement of works the enclosure will be re-smoke tested. On completion of a satisfactory smoke test and negative pressure check works may commence within the enclosure. The carrying out of the smoke test should be recorded on the appropriate Active Environmental form. Following the commencement of asbestos removal works should major leaks or damage to the enclosure be noted the works enclosure will be subject to re-smoke testing. Where an enclosure remains operational for more than 1 week re-smoke testing of the enclosure will be carried out on a weekly basis.

30 10.6 Procedures for daily inspection We at Active Environmental carry out daily inspections of each enclosure prior to the works commencing and half an hour before leaving site at the end of the shift. We have a statutory inspection report format that needs to be filled-in and signed by the designated supervisor on a daily basis. Supervisors are to carry out daily checks in order to assess the following: NPUs are fully operational and that a suitable level of negative pressure has been maintained during the works. That the enclosure is of sound construction and the seals are intact. That the enclosure, associated equipment and methods of work comply with current regulatory requirements. All checks are to be recorded within the site pack and signed off daily by the supervisor Semi enclosed works In accordance with the Control of Asbestos Regulations 2012 works will be undertaken under semi enclosed conditions when the following conditions apply: 1. Airborne fibres levels will be maintained below the controls limits of 0.6 f/ml (averaged over a 10 minute period) and 0.1f/ml (averaged over 4 hours). 2. Where fibres are firmly bounded in a matrix (e.g. Asbestos cement, Aertex, bitumen products, vinyl floor tiles etc) or materials which contain asbestos where its thermal/acoustic properties are not its main purpose. 3. Short duration works (no longer than 2 hours in total for all works, inclusive of setting up/ancillary works) and are completed in accordance with condition 1 (as noted above). Semi enclosed works will be adopted in accordance with the conditions outlined above, in all cases works with asbestos materials will be completed by trained Active Environmental staff in accordance with company standards and in compliance with all relevant regulations. Method statements for works of this nature will ensure that effective fibre control is maintained for the duration, the assessment of the works will take into account previous fibre release data, HSE guidance and legislative requirements. Semi enclosed works will be carried out without the erection of a full enclosure. Semi enclosed works will be divided into Type I, Type II and Type III levels of control Type I controls The work area is to be segregated from surrounding areas using barrier tape. Where practicable the tape should be erected to create a safety gap of 3.0m around the work area and entry / exit doorways etc should be taped off. Prohibition and mandatory signs will be situated on and around the perimeter and entrance / exit points of the work area to prevent unauthorised access. The signs will show: No access for unauthorised personnel Safety overalls must be worn Danger Asbestos hazard Respiratory Equipment must be worn Example(s) Type I works Removal of external AC products, works with vinyl floor tiles, removal of flash guards

31 Type II controls Barrier tape will be erected to entry / exit doorways leading to the work area. The work area will be semi enclosed. 1000g polythene sheeting will be erected to entry / exit points of the work area. The sheeting will be erected to provide a single weighted flap to the main entry / exit point to the work area. All other entry / exit points will be sealed over with 1000g polythene. Where the method statement or supervisor deems it necessary the fixtures, fittings and structural features (floor, walls etc) will be protected with 1000g polythene. All polythene is to be fixed into place using spray adhesive, 75mm pcl tape and staples. All edges will be sealed with 75mm pcl tape. Where necessary a wooden frame (50mmx50mm timbers) may need to be erected to support the polythene. Frame edges will be sealed with 75mm pcl tape. Prohibition and mandatory signs will be situated on and around the perimeter and entrance / exit points of the work area to prevent unauthorised access. The signs will show: No access for unauthorised personnel Safety overalls must be worn Danger Asbestos hazard Respiratory Equipment must be worn Example(s) of Type II Works Removal of Nail fixed AC sheeting (e.g. ceiling panels), wrap and cut of paper based pipe insulation (internal), minor works to AIB (e.g. removal of good condition screw fixed board A Type III controls The work area will be semi-enclosed. A two stage airlock will be provided at the entry point to the works area, decontamination equipment to be provide within/adjacent the airlock. All others entry points will be sealed using 1000 gauge polythene secured by 75mm pcl tape. The floor will be covered, using 1000 gauge polythene secured by 75mm pcl tape. Where the method statement or supervisor deems it necessary the fixtures, fittings and structural features (walls etc) will be protected with 1000g polythene. All polythene is to be fixed into place using spray adhesive, 75mm pcl tape and staples. All edges will be sealed with 75mm pcl tape. Where necessary a wooden frame (50mmx50mm timbers) may need to be erected to support the polythene. Frame edges will be sealed with 75mm pcl tape. Prohibition and mandatory signs will be situated on and around the perimeter and entrance / exit points of the work area to prevent unauthorised access. The signs will show: No access for unauthorised personnel Safety overalls must be worn Danger Asbestos hazard Respiratory Equipment must be worn Example(s) of Type III Works Removal of Artex and associated substrate (e.g. removal of Artex and plasterboard and/or chipboard). Note: For works involving the removal of Artex from a permanent substrate (e.g. concrete ceiling) Active Environmental will complete these works under fully enclosed conditions following a suitable assessment.

32 Procedures for daily inspection (semi enclosed areas) We at Active Environmental will carry out daily inspections of a work area prior to the works commencing and half an hour before leaving site at the end of the shift. Supervisors are to carry out daily checks in order to assess the following: That the work area is suitably segregated and any seals are intact. That the work area associated equipment and methods of work comply with current regulatory requirements. All checks are to be recorded within the site pack and signed off daily by the supervisor. 11. FIBRE SUPPRESSANTS 11.1 Selection of fibre suppressants Fibre suppressants used by Active Environmental will conform to industry standards (e.g. A Strip). The fibre suppressant will be mixed in solution with water to give a minimum strength solution of 15(water):1(suppressant) and maximum strength solution of 10: Methods of application Fibre suppressant solution will be applied through a low pressure hand held spray applicator, or a low pressure powered spray applicator ( Greco type pump), or a suitable wet injection system. The type of fibre suppressant applicator to be used will be specified within the method statement of a particular job Application of fibre suppressant from a hand held spray A hand held spray applicator will be used on site for general damping down and fibre suppressant activities. Where the spray is to be directed directly at an asbestos containing material the spray head will be adjusted to provide a consistent rate of flow of fibre suppressant solution at a velocity sufficient to dampen the asbestos without disturbing it. Care will be taken to ensure that all ACMs are wetted sufficiently to assist in controlling fibre release (they should maintain their form but have a plasticine consistency), but are not overly wetted such that they become a slurry Application of fibre suppressant from a powered spray applicator ( Greco type machine) A low pressure powered spray applicator ( Greco type pump) may be required where large areas of ACMs are being removed and a hand held spray applicator would not provide sufficient volume / coverage of fibre suppressant solution. Where the spray is to be directed directly at an asbestos containing material the spray head will be adjusted to provide a consistent rate of flow of fibre suppressant solution at a velocity sufficient to dampen the asbestos without disturbing it. Care will be taken to ensure that all ACMs are wetted sufficiently to assist in controlling fibre release (they should maintain their form but have a plasticine consistency), but are not overly wetted such that they become a slurry.

33 11.5 Wet injection systems Multi needle injection systems utilised by Active Environmental will conform to BS8520. The wetting equipment will be capable of delivering a wetting solution to an asbestos containing material via valves and needles. The valves will be capable of being set or locked to a position. The volume of wetting solution delivered to each needle will be within ±10% of the average and will aim to give a rate of flow of around 15ml to 60ml per minute (depending on the material being injected). Where mains water pressure is used to deliver the wetting solution it should be sufficient to enable delivery of the wetting solution. The inlet pressure should be controllable via a pressure regulating valve. Where mains water pressure is not sufficient a pressure booster will be fitted to enable adequate delivery of the wetting solution. The injection system will be thoroughly examined and checked before each use. Where items are faulty or damaged they will be replaced. The injection system will be thoroughly cleaned on completion of the works or daily, whichever is the sooner. The injection system will be serviced and certified by a competent person yearly or sooner if required. When using the injection system care will be taken to ensure that all ACMs are wetted sufficiently to assist in controlling fibre release (they should maintain their form but have a plasticine consistency), but are not overly wetted such that they become a slurry Training Personnel on wet injection techniques When using a Multi-Needle Injection system we at Active Environmental will ensure operatives have appropriate training in the correct and safe use of injection machines. Relevant training certification will be provided on site with a further copy of the certificate held at 777 s head office.

34 12. METHODS OF WORK FOR THE REMOVAL OF ASBESTOS CONTAINING MATERIALS 12.1 Selection of methods of work Methods of work for the removal of asbestos containing materials will be selected to facilitate the safest, most appropriate and cost effective removal of the product and will take in to account all current legislative requirements Removal of a sprayed coating using a wet injection system to apply fibre suppressant The wet injection system selected for the works will conform to the standards set out in section The works will be carried out in a methodical manner and will seek to ensure adequate saturation of the material prior to the commencement of any removal works. A fine spray of fibre suppressant will be applied (from a hand held spray applicator) to the surface of the coating prior to the commencement of works. The points at which the injection needles are to be pushed into the coating will have a section of pcl tape affixed to them. This will help to minimize the disturbance of the coating as the needles are put in place. The injection needles will be carefully pushed through the pcl patches and into the surface of the coating at regular intervals (approximately 200mm). The interval between injection needles will depend upon a number of factors (e.g. thickness of the coating, saturation time) and may need to be altered as works progress to ensure that adequate saturation of the ACMs is occurring. Where possible the needles will be placed into the top of the surface to be injected. This will allow gravity to work on the fibre suppressant and aid the saturation process. Once all of the needles are in place the wet injection system will be turned on. The coating will be monitored regularly to assess the spread of the fibre suppressant and the level of saturation. This monitoring will be carried out a minimum of once every hour whilst the wet injection system is in operation. The saturation of the coating will be assessed visually and physically by the site supervisor. The visual inspection will seek to note a colour change to the coating as the fibre suppressant soaks through the material. The physical inspection will require a small screwdriver to be inserted through the coating. The coating should be of a plasticine consistency to its full depth when it is suitably saturated. Over-wetting of the coating will be avoided. It will not be wetted so much that it falls from its substrate or readily forms slurry. Once the coating is suitably saturated operatives will carefully scrape the coating from its substrate using hand tools (scrapers). The coating will be deposited into red asbestos waste bags as it is removed from the substrate. If during the removal of the coating unsaturated areas are identified they will be wetted using a fine spray of fibre suppressant applied from a hand held applicator and removed using hand tools. The substrate will be cleaned using wetted wire brushes, tack rags and h-type vacuum cleaners to remove all visible traces of asbestos material.

35 12.3 Removal of a sprayed coating using a spray applicator to apply fibre suppressant The spray applicator system selected for the works will conform to the standards set out in section 11.3 and / or The works will be carried out in a methodical manner and will seek to ensure adequate saturation of the material prior to the commencement of any removal works. A fine spray of fibre suppressant will be applied to the surface of the coating. This process will be repeated at regular intervals. The interval between applications will depend upon a number of factors (e.g. thickness of the coating, saturation time) and may need to be altered as works progress to ensure that adequate saturation of the ACMs is occurring. Where possible the spray will be applied to the top of the surface of the coating. This will allow gravity to work on the fibre suppressant and aid the saturation process. The coating will be monitored regularly to assess the spread of the fibre suppressant and the level of saturation. This monitoring will be carried out a minimum of once every half hour whilst the fibre suppressant is being applied. The saturation of the coating will be assessed visually and physically by the site supervisor. The visual inspection will seek to note a colour change to the coating as the fibre suppressant soaks through the material. The physical inspection will require a small screwdriver to be inserted through the coating. The coating should be of a plasticine consistency to its full depth when it is suitably saturated. Over-wetting of the coating will be avoided. It will not be wetted so much that it falls from its substrate or readily forms slurry. Once the coating is suitably saturated operatives will carefully scrape the coating from its substrate using hand tools (scrapers). The coating will be deposited into red asbestos waste bags as it is removed from the substrate. If during the removal of the coating unsaturated areas are identified they will be wetted using a fine spray of fibre suppressant applied from a hand held applicator and removed using hand tools. The substrate will be cleaned using wetted wire brushes, tack rags and h-type vacuum cleaners to remove all visible traces of asbestos material Removal of pipe insulation using a wet injection system to apply fibre suppressant The wet injection system selected for the works will conform to the standards set out in section The works will be carried out in a methodical manner and will seek to ensure adequate saturation of the material prior to the commencement of any removal works. A fine spray of fibre suppressant will be applied (from a hand held spray applicator) to the surface of the insulation prior to the commencement of works. The points at which the injection needles are to be pushed into the insulation will have a section of pcl tape affixed to thermo and wrapped in cling film. This will help to minimize the disturbance of the insulation as the needles are put in place. The injection needles will be carefully pushed through the pcl patches / cling film and into the surface of the insulation at regular intervals (approximately 200mm). The interval between injection needles will depend upon a number of factors (e.g. thickness of the insulation, saturation time) and may need to be altered as works progress to ensure that adequate saturation of the ACMs is occurring. Where possible the needles will be placed into the top of the surface to be injected. This will allow gravity to work on the fibre suppressant and aid the saturation process. Once all of the needles are in place the wet injection system will be turned on.

36 The insulation will be monitored regularly to assess the spread of the fibre suppressant and the level of saturation. This monitoring will be carried out a minimum of once every hour whilst the wet injection system is in operation. The saturation of the insulation will be assessed visually and physically by the site supervisor. The visual inspection will seek to note a colour change to the insulation as the fibre suppressant soaks through the material. The physical inspection will require a small screwdriver to be inserted through the insulation. The insulation should be of a plasticine consistency to its full depth when it is suitably saturated. Over-wetting of the insulation will be avoided. It will not be wetted so much that it falls from the pipe or readily forms slurry. Once the insulation is suitably saturated operatives will carefully scrape the insulation from the pipe using hand tools (scrapers). The insulation will be deposited into red asbestos waste bags as it is removed from the pipe. If during the removal of the insulation unsaturated areas are identified they will be wetted using a fine spray of fibre suppressant applied from a hand held applicator and removed using hand tools. The pipe will be cleaned using wetted wire brushes, tack rags and h-type vacuum cleaners to remove all visible traces of asbestos material Removal of pipe insulation using a spray applicator to apply fibre suppressant The spray applicator system selected for the works will conform to the standards set out in section 11.3 and / or The works will be carried out in a methodical manner and will seek to ensure adequate saturation of the material prior to the commencement of any removal works. A fine spray of fibre suppressant will be applied to the surface of the insulation. This process will be repeated at regular intervals. The interval between applications will depend upon a number of factors (e.g. thickness of the coating, saturation time) and may need to be altered as works progress to ensure that adequate saturation of the ACMs is occurring. Where possible the spray will be applied to the top of the surface of the coating. This will allow gravity to work on the fibre suppressant and aid the saturation process. The insulation will be monitored regularly to assess the spread of the fibre suppressant and the level of saturation. This monitoring will be carried out a minimum of once every hour whilst the fibre suppressant is being applied.

Over-wetting of the insulation will be avoided. It will not be wetted so much that it falls from the pipe or readily forms slurry. Once the insulation is suitably saturated operatives will carefully scrape the insulation from the pipe using hand tools (scrapers). The insulation will be deposited into red asbestos waste bags as it is removed from the pipe. If during the removal of the insulation unsaturated areas are identified they will be wetted using a fine spray of fibre suppressant applied from a hand held applicator and removed using hand tools. The pipe will be cleaned using wetted wire brushes, tack rags and h-type vacuum cleaners to remove all visible traces of asbestos material.

37 12.6 Removal of pipe insulation using the wrap and cut technique A fine spray of fibre suppressant will be applied to the surface of the insulation from a hand held spray applicator. The section of insulated pipe will be wrapped in 1000g polythene sheeting and sealed with adhesive spray and 75mm pcl tape. The pipe will be cut at natural break points / non insulated areas (e.g. flanges, support brackets) using a reciprocating saw. The cut points will not be so far apart as to make the handling / manoeuvring of cut sections impractical. Where the pipe work cannot be cut at non insulated areas the insulation will need to be removed from the pipe to enable a cut to be made. The insulation will be removed by either using the wet injection technique or spray applied fibre suppressant technique as detailed to sections 11.4 and The most suitable method for removal will be detailed to the method statement. Once the insulation has been removed from the pipe the pipe will be cut at the newly cleaned area. The wrapped pipes will be disposed of as asbestos waste 12.7 Removal of sectional pipe or paper lined insulation A fine spray of fibre suppressant will be applied to the surface of the insulation from a hand held spray applicator. The sections of the insulation will be supported and the binding bands / clasps will be cut using hand tools. The sections of the insulation will be carefully eased from the pipe. Fibre suppressant solution will be applied to all dry (internal) surfaces of the insulation as they are revealed. The sections will be placed into asbestos waste bags for disposal. The pipe will be cleaned using wetted wire brushes, tack rags and h-type vacuum cleaners to remove all visible traces of asbestos material Removal of insulation debris A fine spray of fibre suppressant will be applied to the insulation debris from a hand held spray applicator. Small areas of debris are to be cleaned up using H type vacuums. Larger pieces of debris will be sprayed with a fine mist of fibre suppressant solution, removed by hand and placed into asbestos waste bags. Scrapers will be used to scrape large pieces of wetted debris from surfaces. Dampened wire brushes will be used to remove traces of insulation from contaminated surfaces Removal of AIB panels / tiles (screw fixed) A fine spray of fibre suppressant will be applied to the AIB. Where there is sufficient access operatives will seek to apply fibre suppressant to all available faces of the product (e.g. apply fibre suppressant into a ceiling void to coat the tops of AIB tiles). The screw fixings will be located and carefully unscrewed using hand tools. The nozzle of an H- type vacuum cleaner will be held adjacent to the work area as the fixings are unscrewed.

38 Where the AIB product cannot be unscrewed (e.g. screw heads are worn, decayed or cannot be located) then the following method of removal will be used: The AIB will be wetted using fibre suppressant. Hand tools will be used to prise the panels and fixings from the supporting frame. Panels will be removed intact wherever possible. Areas of panel around immovable fixings will be carefully broken such that panelling may be removed in as large a section as reasonably practicable. Where breakages to the panels are unavoidable they will be kept to a minimum. Fibre suppressant will be applied as necessary as the works proceed. Screw fixings will be removed from supporting frames and the screw holes will be cleaned out to remove traces of asbestos containing materials Removal of AIB panels / tiles (nail fixed) A fine spray of fibre suppressant will be applied to the AIB. Where there is sufficient access operatives will seek to apply fibre suppressant to all available faces of the product (e.g. apply fibre suppressant into a ceiling void to coat the tops of AIB tiles). Hand tools will be used to prise the panels and fixings from their supporting frame. Panels will be removed intact wherever possible. Areas of panel around fixings will be carefully broken such that panelling may be removed in as large a section as reasonably practicable.

The workface and surrounding area will be continually sprayed down with fibre suppressant solution as works progress. Debris will be cleaned up and placed in to red asbestos waste bags as the works progress. After the heavy plaster has been removed the remaining residue will be saturated with fibre suppressant solution. When the substrate is completely saturated the remainder of the residue will be removed using hand tools Removal of AC roof sheets (from work platforms) The roof sheets will be wetted. Where possible the metal fixings for the sheets will be cut using bolt croppers or reciprocating saws and the sheets will be removed whole. Where breakages are unavoidable they will be minimised as far as reasonably practicable. All materials will be wetted as works are carried out. As products are released from their fixings they will be lowered to the work platform. The platform (or sheeting) will be lowered to the floor at regular intervals (so as not to overload the work platform) and the sheets loaded into a lined (1000g polythene) skip or lorry for disposal as asbestos waste. The work platform and works area will be cleaned daily to remove dirt and debris generated by the works and prevents its accumulation.

41 12.21 Removal of AC roof sheets by remote demolition Controlled remote demolition of AC roof areas will be carried out to structures where safe access and working from mobile platforms cannot be achieved. The internal of the structure will be cleared of all obstructions and debris such that a clean, sound base is available to receive the collapsed roof. The roof sheets will be wetted using fine sprayed water applied from a hose. Long reach heavy plant equipment will be used to carefully collapse and lower the roof sheets and supporting framework to the floor of the building. Plant operatives will seek to control the demolition as far as is reasonably practicable and minimize breakages to the roof sheets. As works progress a fine spray of water will be continually applied to the works area. Sandbags / booms will be used to contain excess water run off. On completion of the lowering of the roof, sheeting will be loaded onto Bobcat mini diggers and transferred to lined skips or lorries for disposal. Operatives will pick through the site and clean all AC debris from the area prior to the commencement of further demolition works Removal of AC panels (screw fixed) A fine spray of fibre suppressant will be applied to the AC. Where there is sufficient access operatives will seek to apply fibre suppressant to all available faces of the product (e.g. apply fibre suppressant into a ceiling void to coat the tops of AC panels).

The fixings for the items will be severed using hand tools and the sink unit / cisterns disposed of as asbestos waste Fine cleaning of enclosures Following the removal of asbestos containing materials as per the method statement all enclosures are to be cleaned using hand tools, tack rags and H-type vacuum cleaners to remove visible asbestos debris and associated dust and dirt. Consideration should be given to the removal and disposal of non cleanable materials (e.g. wood, mmmf) as asbestos waste wherever practicable. Friable surfaces and / or materials (e.g. old brick plaster or paint) should be cleaned to remove loose debris and materials.

44 12.33 Cleaning and checking of semi enclosed works areas All work areas will be cleaned using appropriate hand tools, tack rags and H-type vacuum cleaners to remove visible traces of asbestos containing materials. The works area will be checked by the supervisor to ensure that all visible asbestos containing materials have been removed. Consideration should be given to the removal and disposal of non cleanable materials (e.g. wood, mmmf) as asbestos waste wherever practicable. 13 WASTE It is the policy of this company that where waste is generated during the course of company activities then that waste shall be disposed of in a controlled, safe and proper manner. Where such waste removal requires the application of special control measures to reduce hazards such as contamination, dust or risk of environmental pollution then laid down company procedures will be followed to render such waste removal inoffensive and free of risk so far as reasonably practicable. Such procedures are specified within this document. Asbestos waste is classified as Hazardous Waste when the concentration of asbestos exceeds 0.1% by volume Waste Handling The work area will be cleaned as works progress. All waste and debris will be placed in to asbestos waste bags or wrapped in polythene (and sealed with 75mm pcl tape) as it is generated. Asbestos materials will not be deliberately broken or damaged in order to make them fit into waste bags. Large or unwieldy items will be wrapped in 1000g polythene sheeting, be sealed with 75mm pcl tape and disposed of as a complete unit. Wrapped waste will be suitably labelled - as per CAWR requirements (UN asbestos waste bags to be tape applied to outside of wrapped waste) Bags will not be overfilled with waste, all bags to be used will be UN approved waste sacks.. Full waste bags will have excess air removed from them by inserting an H type vacuum into the neck of the bag. Once the excess air has been removed the neck of the bag will be tightly twisted round, taped with 75mm pcl tape, folded over (to form a swan s neck) and taped with 75mm pcl tape again. The sealed bags will be stored in a suitable area of the enclosure (i.e. where damage is unlikely to occur or dirt and debris is unlikely to get on them). At the end of each working shift waste materials that are capable of being transited from the work area will be removed and transferred to a secure storage area / skip or van for removal from site and disposal. Transit routes for waste removal will be identified to the Method of work. Transit route direction signs should be erected at regular intervals along the route so that the appropriate path is clearly delineated. Once removed from the bag lock waste items should not be left unattended and will be taken directly to the secure storage facility. The person transporting the waste will wear coveralls and ½ masks when transporting waste. Waste shall not be thrown into the skip, sharp items shall not be mixed in with the waste. Where possible an outside man will remove the bagged waste direct to the skip.

45 13.2 Waste removal procedures (full enclosures) When transiting waste from a fully enclosed work area operatives will carry out the following procedures: (See next page) Wipe down the waste bags with tack rags and pass them into the inner (dirty) stage of the air / bag lock Clean the waste bags with an H-type vacuum, spray them with a fine mist of fibre suppressant solution applied from a handheld spray applicator and pass them to the middle section of the air / bag lock Immediately place the waste into a clear polythene second outer waste bag, extract excess air from the bag by inserting an H type vacuum into the neck of the bag. Once the excess air has been removed the neck of the bag will be tightly twisted round, taped with 75mm pcl tape, folded over (to form a swan s neck) and taped with 75mm pcl tape again Pass the waste bag to the outer air / bag lock for transiting to the designated waste storage area

46 13.3 Waste removal procedures (semi enclosed work areas) When transiting waste from a semi-enclosed work area operatives will carry out the following procedures: At the entry / exit point to the work area the waste bags will be wiped down with tak rags, cleaned with an H-type vacuum, wetted with a fine mist of fibre suppressant solution applied from a handheld spray applicator and immediately placed into a clear polythene second outer waste bag. The excess air will be extracted from the bag by inserting an H type vacuum into the neck of the bag. Once the excess air has been removed the neck of the bag will be tightly twisted round, taped with 75mm pcl tape, folded over (to form a swan s neck) and taped with 75mm pcl tape again The waste bag will then be passed out of the work area for transiting to the designated waste storage area

47 13.4 Disposal of materials used to form a work area (enclosure) All non cleanable materials (polythene, wood etc.) used to form the internal face / structure of a work area will be disposed of as asbestos waste on the completion of works. Where large areas of polythene sheeting are to be disposed of as waste a strong PVA solution can be applied to the area prior to dismantling. Note: PVA should not be applied to the sheeting until after a successful visual inspection and clearance air test(s) have been carried out Waste storage facilities Containers utilised for waste storage will be watertight, sealable and lockable. Appropriate warning notices will be posted to the external faces of the container. The container will be locked when waste is not being transited to it. Waste containers (skips) will be removed at the end of the contract removal period Waste storage facilities (skip) will be located as close as possible to the works area and will avoid sensitive locations. Where waste packages become damage in transport the container should be decontaminated and subject to disturbed air testing Waste Transport All waste classified as hazardous (above 0.1% asbestos) to be removed from site will be correctly stored and labelled in accordance with the CDG / CAWR regulations. CDG regulations will not apply where asbestos is contained in a firmly bound matrix (e.g. asbestos cement / textured coatings / thermo plastic products) In order to carry licensed waste materials (asbestos) the company will hold the required Environment Agency license and waste will be moved with a section 62 consignment note present Where the company provides its own vehicles for transportation of waste materials they will have a sealed bulk head between the cab and the waste compartment, waste materials will also be physically segregated from the reminder of the vehicles load (e.g. tools) to prevent accidental damage of the packages.

48 The following summarises the requirements when carrying waste in company vehicles: Is vehicles: the asbestos is contained in a firmly bound matrix (e.g. asbestos cement / textured coatings / thermo plastic products)? YES - CDG does not apply, move waste under details of consignment note NO See Below Does the maximum weight of the vehicle exceed 3.5 tonnes? YES Driver will need ADR training, vehicle will need fire extinguishers, Tremcard to be present in cab and orange panels to be displayed front and rear NO See Below If the vehicle weight is less than 3.5 tonnes, is more than 333Kg of Blue or Brown asbestos or 1000kg of White asbestos being carried? YES Orange Panels to be displayed front and rear NO Orange panels not required 14. PERSONAL MONITORING 14.1 Frequency of personal testing We at Active Environmental Services will have our operatives personally monitored at an equivalent to those stated below: Product Typical Asbestos Content Frequency of Monitoring Spray Coating 85% 100% (1 operative) Asbestos Insulation 85% 50% (1 operative) AIB 16-40% 4 times per year Non-licensable items 3-100% As required (dependent on condition) The results of personal monitoring will be examined on a regular basis to ensure that our work methods comply with current legislative requirements. Where personal monitoring results identity elevated fibre levels, the site supervisor will stop works and contact the Active Environmental office / management to discuss actions taken to ensure fibre levels are controlled better at source through wetting / removal techniques. When works recommence further personal sampling will be completed to ensure additional controls are effective.

49 Personal air testing results will be recorded along with exposure estimates for each employee as part of their exposure record; personal samples will also be used to define the base line for exposure across the company. Records of employee exposure records will be kept for 40 years. 15. PLANT 15.1 Procedures for inspecting plant prior to works We at Active Environmental will ensure that all plant assigned to a works project has appropriate and suitable test certification which is valid for the proposed duration of the works Standard equipment on site We at Active Environmental will ensure that sufficient plant and equipment is provided to site at the commencement of works to enable work methods and areas to be established as per the method statement and taking in to account current legislative requirements Identifying plant for site records We at Active Environmental have given each item of plant an independent serial number. The serial number is marked on the item of plant and recorded on all associated paperwork and logged in the site data pack Protection of plant during transit We at Active Environmental supply each vehicle with ratchet straps and elasticised luggage straps to secure plant items to the side of the vehicle and reduce the risk of breakage and damage to the plant while being transited Procedures for hiring plant We at Active Environmental will only use registered companies for plant hire. Our selected suppliers will issue new DOP and PAT test certificates with all plant hire. On delivery of any item of plant we will check that all serial numbers correspond with the sent paperwork. Where the paperwork / plant do not correspond with each other or are out of test we will return the item immediately Licensed Scaffolders We at Active Environmental will employ the use of HSE licensed asbestos scaffolding contractors where it is foreseeable that the scaffolding activity is likely to disturb the asbestos. All licensed asbestos scaffolding works will be subject to separate notification by the licensed asbestos scaffolding contractor employed by Active Environmental. The scope for using a licensed scaffold contractor will be define as per the HSE ALG 01/10

50 17.0 COSHH - CONTROL OF SUBSTANCES HAZARDOUS TO HEALTH We at Active Environmental use the following products on a regular basis: PVA Active Environmental - COSHH ASSESSMENT SHEET 03 (PVA) Disinfectant Active Environmental - COSHH ASSESSMENT SHEET 04 (DISINFECTANT) Expanding foam Active Environmental - COSHH ASSESSMENT SHEET 05 (FOAM AEROSOL) Spray Tack Active Environmental - COSHH ASSESSMENT SHEET 06 (SPRAY TAK) Smoke/Fog Active Environmental - COSHH ASSESSMENT SHEET 07 (FOG) Astrip Concentrate Active Environmental - COSHH ASSESSMENT SHEET 08 (ASTRIP CONC.)

If the substances are to be used in conditions for which they are not normally manufactured (e.g. extremes of temperature), we will contact the manufacturer of the product to confirm safe methods of use ELECTRICAL SAFETY We at Active Environmental will only use 110v power supplied from transformers or generators for site works. Where the existing building supply is used (e.g. 240v) then the supply will be regulated through a RCD device and a transformer with the exception of dcu s whereby the use of a 240v supply will be permitted complete with an RCD device. Each item of electrical equipment is checked periodically at six monthly intervals or sooner. Pat certificates will be present for all pieces of electrical equipment.

51 FULL DETAILS CAN BE FOUND IN THE COMPANY PROCEDURES MANUAL 19.0 EMERGENCY PROCEDURES 19.1 General procedures 1. Raise the alarm. (If you are not near an alarm device shout FIRE and give the LOCATION). 2. When contacting the emergency services remember to give the following details: THE ADDRESS OF THE FIRE; BRIEF DETAILS (e.g. FIRE IN THE GROUND FLOOR); THE PHONE NUMBER THAT YOU ARE CALLING FROM; 3. Evacuate the area by designated escape routes. 4. Only try to put the fire out if it is possible to do so without putting yourself or others in danger Site procedures and general responsibilities It is the policy of this company that suitable and sufficient fire and emergency procedures be in place at each site, in order to facilitate effective evacuation, or other appropriate action, and to ensure that an operative s health and safety is not put at risk unduly during the course of such action. The following is an example of the type of procedures that would be put in place at the site, although it is possible that these procedures may be more detailed / complicated depending on the nature, extent and complexity of the site, and if there are any existing emergency/fire procedures in place on the site. It is the supervisor s responsibility to check and / or instigate site emergency procedures. Fire Precautions Each site occupied by Active Environmental personnel will have a specified fire point. This will include two fire extinguishers. Before site set up the site supervisor will make himself aware of any emergency exits and escape routes. He will inform all operatives of where the fire fighting equipment is situated and where the escape routes and exits are. He is also responsible for informing the operatives of where the fire assembly point shall be. Under no circumstances shall any Active Environmental Employee try to tackle a fire that they believe to be out of their control. Action on discovery of a fire: Inform the site manager who will alert the fire brigade by telephone and inform anyone else in the building/on site. Action on hearing the alarm: Evacuate the premises quickly and quietly. Do not wait to finish a phone call or to collect personal belongings. Report to the assembly point. Do not reenter the building until the senior fire officer on the site declares that it is safe to do so.

52 Summoning the Fire Brigade Due to the nature of the premises/site it will not always be possible to have a designated fire warden in each area. It is imperative therefore that each member of staff ensures that their area is evacuated and that everyone, including visitors are alerted and cleared from the premises. That information should be reported to the senior person in charge at the fire assembly point. Fire or Explosion The following action is to be taken in the event of a fire or explosion occurring on site: a) The fire brigade is to be summoned immediately. b) Full details of the incident are to be passed to the Site Supervisor as soon as possible.

Vacuum visible dust and fibres from PPE / RPE and footwear. Brush footwear in footbath. Remove coveralls and footwear Do not remove RPE Pass into middle stage of airlock. Sponge down or wipe RPE Pass into outer stage. Put on transit overalls and transit footwear. Walk to DCU via designated transit route As the operatives exit the enclosure the supervisor will carry out a roll call to ensure no personnel are absent. Operatives will enter the dirty end of the DCU. Take off all footwear, coveralls and underwear and place in storage or disposal bags. Transit footwear should be cleaned and stored. Disposable coveralls and other items should be placed in red asbestos waste bags and sealed at the neck for disposal as asbestos waste. Do not remove RPE Move to shower area with respirator on. Shower and use a sponge to clean RPE without allowing water on to filter ports Start drying off. Place towel in bag for disposal or laundering Once RPE has been cleaned, remove it and shower yourself thoroughly. Remove used filters and place in waste bag for disposal Pass through into clean end and complete drying with a different towel(s). Dress Leave DCU via clean end external door. The supervisor should carry out a second roll call to confirm that all operatives are present.

55 19.5 Minor Accidents / Injuries within enclosures (where the injured party is able to mobilise themselves) In the event of a minor accident within an enclosure the following procedures will be carried out: a) Operatives will inform the outside man of the incident and request that they phone for an ambulance and / or locate the nominated first aider. b) The nominated first aider will assess the injured person (as required), once assessed if the injury is deemed to be major the emergency services will be contacted and the procedures followed as per CSP c) Where the operative can self-mobilise (e.g. leave the enclosure) without causing further harm he/ she will be accompanied through the decontamination process. d) Once decontaminated the nominated first aider will reassess and give any required treatment to the injured party, where applicable the operative will leave site to receive further treatment (as required). c) The Active Environmental Supervisor will inform the office and investigate the incident Major Accidents / Injuries within enclosures (where the injured party is immobilised) In the event of a major accident within an enclosure the following procedures will be carried out: a) Operatives will inform the outside man of the incident and request that they phone for an ambulance, the fire brigade and locate the nominated first aider. b) The works area will be checked to ensure it is safe for person to assist the injured party c) The nominated first aider is to give first aid to the injured party until the emergency services arrive. d) Operatives will clean and tidy the enclosure as far as reasonably practicable and spray down the area with fibre suppressant solution. e) Once the emergency services have arrived the supervisor should inform them of the type of works being undertaken and the associated risks. f) The fire brigade should be allowed to control the rescue and decontamination of the injured party, Active Environmental will liaise/assist with all operations as required by the emergency services. g) The Active Environmental Supervisor will inform the office and investigate the incident. Note: It should be noted that the fire brigade is the only emergency service that is fully equipped to enter into a contaminated asbestos enclosure. Therefore, they must be called to all major incidents Decontamination following spillages / leaks from enclosures Accidental spillage from asbestos waste bags If during the transit of asbestos waste a bag should split or become damaged operatives will: a) Immediately seal the bag using 75mm poly cloth tape and place into a new red asbestos waste bag. The bag shall then be double bagged with a clear asbestos waste bag and sealed.

56 b) The immediate area will be evacuated and sealed off using hazard warning signs and barrier tape. c) Suitably protected operatives will then clean the area using a H - type vacuum unit and Tak-Rags. d) The area will then be lightly sprayed with a solution of fibre suppressant. e) On completion of the clean up an independent analyst (if on site) will visually check the area and carry out air monitoring to confirm the area is suitably clean. If an analyst is not on site the supervisor is to assess the situation and act in accordance with current legislative requirements. f) On completion of a satisfactory clean up operation the area is to be returned to normal occupation Minor leaks from enclosures (fibre concentration < 0.1 f/ml air sampled) If during removal works a breach of the enclosure is detected then the supervisor will: a) Inform the foreman inside the enclosure to cease works immediately. b) Spray the enclosure area with fibre suppressant solution. c) Change the pre-filters on the negative pressure unit(s). d) Repair the breach from inside and outside the enclosure. e) Prior to the re-commencement of works a full investigation of the problem will take place. This may include further smoke testing and a re-evaluation of the negative pressure Major leaks from enclosures (fibre concentration 0.1 f/ml air sampled) If during removal works a breach of the enclosure is detected then the supervisor will: a) Inform the foreman inside the enclosure to cease works immediately. b) Designate the area adjacent to the enclosure a respirator zone and evacuate it. c) Erect barrier tape and suitable warning notices to segregate the contaminated area. d) Only allow operatives in suitable PPE and RPE to enter the segregated zone. e) Spray the internal of the enclosure and adjacent areas with fibre suppressant solution. f) Change the pre-filters on the negative pressure unit(s). g) Repair the breach from inside and outside the enclosure. h) On completion of the clean up an independent analyst will visually check the area and carry out air monitoring to confirm the area is suitably clean. i) Prior to the re-commencement of works a full investigation of the problem will take place. This may include further smoke testing and a re-evaluation of the negative pressure Failure of DCU When working onsite there maybe occurrences where the onsite DCU fails due to mechanical failure (boiler faults) or disruption in services (power and water supply). On such occasions the following steps will be taken:

57 a) Works within the enclosure will be ceased b) The site supervisor will contact the Active Environmental office with details of the problem c) Where possible alternative supplies will be found (e.g. use of generator / bowser / delivery of new DCU), where this can be achieved quickly operatives will remain in the enclosure until such time that the necessary equipment has arrived onsite and the DCU is operational (works will recommence). *Active Environmental have hire equipment suppliers that provide a nationwide chain of branches, thus in such cases as power failure the provision of temporary equipment (i.e. portable generators) should be made available (subject to individual store locations(s)/ availability) within a reasonable time period so as to provide the required services for dcu operation.* Where alternatives arrangements cannot be made quickly / prior to the end of the shift then the following steps will be taken: a) Works in the enclosure will cease b) Additional decontamination equipment will be made available in the airlock c) Operatives will decontaminate within the airlock, further attention will be paid to ensure the operatives clean themselves prior to changing into transit coveralls. d) Operatives to proceed to the DCU, here temporary facilities will be provided, this may include the use of bottled water (for showering). e) Operatives will be advised to dress in coveralls and return to the Active Environmental yard for full decontamination prior to returning home / donning clothing Failure of power within works enclosure When working on site there maybe an occurrence where the power supplies to the enclosure fails due to disruption in services (i.e. power cut/ generator failure). On such occasions the following steps will be taken: a) Works within the enclosure will be ceased b) The site supervisor will contact the Active Environmental office with details of the problem c) Where a self contained dcu is present on site the dcu will be powered via the on-board generator system/ stand alone generator. In such instances operatives will exit the works enclosure (enclosure airlock/ bag lock openings to be sealed upon leaving enclosure) and decontaminate as per CSP s, works will not continue within the enclosure until suitable power has been restored. d) Where the power disruption affects the DCU in addition to the enclosure, CSP s will be followed as per
