INTRODUCTION According to regulations, asbestos is defined as the fibrous form of mineral silicates belonging to rock forming minerals of the serpentine group, that is, chrysotile, and the amphibole group, that is, actinolite, amosite, anthophyllite, crocidolite, tremolite, or any mixture containing one or more of these minerals. The mineral is described as resistant and even indestructible, since it tolerates abrasion, the corrosive effect of chemical products and very high temperatures (flames). In addition to its qualities as a thermal and electrical insulating material, asbestos is relatively cheap. Once the fibres have been extracted, the product can be marketed without having to undergo a sophisticated transformation process. Asbestos came to be widely used during World War II, and in 1950, Underwriters Laboratories approved it as a fireproofing material. From 1950 to the present day, it has been used in a variety of applications: in car brakes, as fireproofing in construction, as a thermal insulation, etc. During the 1970 s, its use began to wane because of potential health hazards related to asbestos-containing materials (ACM). Its use was banned in 1978. SCOPE The objective of this program is to ensure that asbestos-containing material in University buildings is managed such that the health of maintenance workers and building occupants is safeguarded. This program applies to all buildings and structures owned by Concordia University, to all employees and students of the University and to external organisations including contractors hired by the University who may come into contact with or disturb asbestos containing material in University buildings. Quebec has developed stringent guidelines with respect to friable asbestos-containing materials in buildings. This is outlined in the "Safety Code for the construction industry" (S-2.1, r.6). The asbestos management program documented here is intended to meet the requirements of this regulation. To conform to Quebec Legislation and general recognized standards of practice, the procedures outlined in the program are to be followed by Concordia University supervisors, employees, and contractors performing any type of work on asbestos containing materials. EHS-DOC-014 v.3 4
The basic elements of the management program are: 1. An initial asbestos survey to identify and record the locations and conditions of all friable asbestos containing material (ACM). Available at Environmental Health and Safety. 2. The preparation of a survey report detailing results from the survey and providing recommendations for remedial action to comply with the Quebec regulations. Available at Environmental Health and Safety. 3. The provision of appropriate procedures for all asbestos-related work that may disturb ACM. 4. Notification of all workers or building occupants that ACM is present so that they can adopt safe work procedures to protect themselves or other occupants of the building. 5. Training and education of workers who may come into contact with ACM. 6. Personal protection for all workers who come in contact with ACM. 7. Inspections and air monitoring at the workplace to ensure that asbestos is being contained in the workplace. 8. Specific criteria for determining abatement completion, control and monitoring of external contractors performing work that may disturb friable ACM. 9. The maintenance of records of all asbestos-related work with ACM. 10. The provision for auditing the implementation and effectiveness of the program. 11. Communication of this program and of asbestos-related work taking place in University buildings to joint health and safety committees and to other persons who may be affected by the work. EHS-DOC-014 v.3 5
DEFINITIONS Asbestos Asbestos is a generic term describing a number of naturally occurring, fibrous, hydrated mineral silicates that differ in chemical composition and are suitable for use as noncombustible, non-conducting and chemically resistant materials. Different types of asbestos that may be found in buildings are chrysotile, amosite, crocidolite, tremolite, actinolite or anthophyllite. Asbestos-Containing Material Any material found to contain 0.1% or greater content of asbestos, as determined by Polarized Light Microscopy. Friable Friable material means material that when dry can be crumbled, pulverized or powdered by hand pressure, and includes such material that is crumbled, pulverized, or powdered. Three types of friable asbestos commonly used in buildings are: Sprayed fibrous fireproofing Decorative or acoustic texture coatings Thermal pipe insulation Non-Friable Generally, non-friable materials cannot be easily crumbled, pulverized or powdered by hand pressure. Common types of non-friable material include: Vinyl floor tiles Asbestos cement products Acoustic tiles Gaskets Seals Plaster Type 1 work Low risk work involving asbestos containing materials. Type 2 work Moderate risk work involving asbestos containing materials. Type 3 work Moderately high risk work involving asbestos containing materials. Type 4 work High risk work involving asbestos containing materials. EHS-DOC-014 v.3 6
HEALTH RISKS Inhalation of asbestos fibres can cause serious health problems. These fibres may remain in the air for many hours if they are released from asbestos containing material (ACM) in a building. When fibres are released into the air, people in the building may be exposed. Inhalation of asbestos fibres may cause diseases that disrupt the normal functioning of the lungs. Three specific diseases have been linked with exposure to asbestos: Asbestosis (a fibrous scarring of the lungs) Lung cancer Mesothelioma (cancer of the lining of the chest cavity) In most cases, these diseases have been associated with heavy exposure over many years. However, mesothelioma may result from shorter exposures to specific types of asbestos, namely crocidolite and amosite (referred to as the amphibole group). These are less frequently found in Canadian buildings than is the more common and less hazardous chrysotile, which was mined in Quebec. Friable ACM presents the greatest hazard to workers. Friable means material that when dry can be crumbled, pulverized or powdered by hand pressure. Three types of friable material commonly used in buildings are: Sprayed fibrous fireproofing Decorative or acoustic texture coatings Thermal pipe, boiler/furnace insulation Workers with a history of smoking are at increased risk of developing lung cancer than are non-smokers. This is mainly because smoking impairs the lungs ability to clear fibres and other foreign materials. Asbestos fibres, which are ingested (swallowed) or which meet the skin cause no particular harm. It is when fibres are inhaled into the lungs that they can cause disease. The presence of asbestos in buildings does not necessarily constitute a health risk to either maintenance workers or other building occupants. It is only when the fibres become airborne that they may become hazardous through inhalation or breathing them into the lungs. Once in the lungs, they cause a biochemical reaction in certain individuals, which may result in disease. It is for this reason that regulations identifying the type and location of asbestos in buildings, controlling the production and dissemination of fibres and the training of workers have been developed. Work with asbestos can be performed safely providing that measures are taken to control the production and spread of asbestos dust and to protect the workers from breathing the fibres. EHS-DOC-014 v.3 7
CONCORDIA BUILDINGS The use of asbestos insulation in buildings was banned in Quebec in the early 70's. In buildings constructed after this date, asbestos is not usually found except in vinyl flooring, tiles, seals and gaskets and in special applications. The potential risk in these cases is the release of fibres, which may occur during the installation or removal, cutting, sawing or shaping of these products. The Visual Arts Building, Vanier Library and the Concert Hall fall into this category. In older buildings like the Administration Building at Loyola, and the older Annexes on the SGW Campus, asbestos will normally only be found on pipe and furnace insulation and in the building products described above. Asbestos fireproofing insulation was not often used before 1940. There are, however, Concordia buildings, which do contain asbestos insulation, usually on supporting beams in walls, and ceilings where it was applied as fireproofing. At SGW, the Hall Building contains asbestos insulation. At Loyola, it is found in parts of the Athletic Complex. A list of University owned buildings, with their construction dates, and possible asbestos containing materials can be found in Appendix A. Any building constructed prior to 1985, is considered as having materials that potentially contain asbestos. It is important to know where asbestos is present so that control measures can be taken to prevent the release of fibres into the air during routine maintenance and renovation work, which may expose both the workers and other building occupants. In 1990, the Quebec Government issued new regulations for work with asbestos products, which are included in the Safety Code for the Construction Industry S-2.1, r.6, article 3.23. In 1999, modifications were made to this code, with respect to work liable to emit asbestos fibres. The University is now obliged to follow these regulations whenever any work is being performed either by its own employees or by contractors. Ideally, all friable ACM should be eventually removed from all University owned buildings. However, budgetary constraints are such that, presently, friable ACM is removed only when major renovations are done. ASBESTOS PROGRAM RESPONSIBILITIES To effectively manage ACM and prevent asbestos exposures, the Asbestos Management Program requires participation by all members of the University community. The overall responsibility for implementing this program is shared between Environmental Health and Safety, Facilities Management, and any department liable to work near asbestos containing material. The following summarizes the key duties and responsibilities. EHS-DOC-014 v.3 8
Industrial Hygiene Manager The asbestos program manager will be the Industrial Hygiene Manager from Environmental Health and Safety and will have the following responsibilities within the asbestos management program. Oversees workplace inspections and prepares/updates the survey report. Monitors all asbestos-related activities in the buildings including operation and maintenance activities and other abatement actions. Provides technical advice to Facilities Management and other University personnel and makes recommendations regarding the identification of asbestos, the health hazards and the control measures related to asbestos. Coordinates ongoing asbestos training and education programs. Evaluates on an ongoing basis the effectiveness of the asbestos management program and recommends changes to the program as appropriate. Conducts and oversees inspections at regular intervals to determine the condition of the ACM and to prepare a report indicating the results. Monitors Custodial and Maintenance personnel, and outside contractors with regard to all asbestos-related activities through periodic site visits to ensure proper work practices. Reviews specifications for outside contractors working in areas where ACM is present. Maintains records of all Type 2, 3, 4 work carried out. Has final authorization in determining level of risk, based on type of work to be carried out, in case of disagreement. Facilities Operations Facilities Operations, through its Managers, Property Managers, Supervisors, Group Leaders and other employees, may authorize, contract or conduct work that may disturb asbestos containing material. The Property Managers and Supervisors have the following responsibilities: To review all maintenance, repairs and renovation work to determine whether friable asbestos-containing materials are present and might be disturbed by such activities. To classify all asbestos work under his/her jurisdiction as Type 1, 2, 3, 4, in consultation with Environmental, Health and Safety, as needed. EHS-DOC-014 v.3 9
To be responsible for all asbestos work (Type 1, 2, 3, 4) performed by his/her employees or by external individuals contracted to do the work, and to ensure that all such work is conducted in accordance with the Asbestos Management Program by regular monitoring of the progress of the work and regular site inspections. To ensure that employees who must perform work on or may disturb ACM have been provided with proper training and education, and PPE, and have been fit-tested for the respirator they have been assigned. Ensure that Contractors comply with the current Asbestos Management Program when working near ACM. To advise the asbestos program manager of all Type 2, 3, 4 asbestos work for which he/she is responsible by filling out the Asbestos permit form. See Appendix B. To respond to reports of asbestos damage or disturbance, and to ensure that appropriate cleanup and abatement are completed in a timely manner. Upon assigning work, supervisors shall call on the means at their disposal (Asbestos Inventory or by contacting Environmental Health and Safety) to determine whether there are ACM near that work. *In emergency situations where the presence of asbestos cannot be assessed prior to commencement of the work, employees shall employ the practices prescribed for working near asbestos, assuming Type 2 risk (as stated in the present document). If the there is any doubt of whether the work area contains asbestos, the supervisor should contact Environmental Health and Safety, which will have to conduct sampling of the materials. The cost of sampling will be at the expense of the department undertaking the work. If it turns out that there are asbestos-containing materials in the contemplated workplace, supervisors are responsible to determine the level of risk (1, 2, 3, 4). See section titled Categories of Asbestos Work Based upon Risk for definitions of different risk levels. If in doubt about risk level, supervisors shall consult Environmental Health and Safety. Work entailing a low to moderate risk (see Employer Obligations-Type 1, 2 ) Upon assigning work, supervisors shall advise employees of occupational risks, appropriate safe work practices, and the protective equipment required for the level of risk at hand (low to moderate). Work entailing a moderately high or high risk (see Employer Obligations-Type 3, 4 ) Must be performed by specialized contractors. Employees or supervisors shall in no case undertake such work. Once work has commenced, supervisors are responsible for ensuring that employees are wearing the appropriate personal protective equipment and are using the safe work practices and techniques prescribed for the level of risk at hand. EHS-DOC-014 v.3 10
Project Management Services Project Managers have the following responsibilities: Prior to starting work, determine if asbestos is present in or around the work to be carried out. If the there is any doubt of whether the work area contains asbestos, the Environmental Health and Safety office will have to conduct sampling of the materials. The cost of sampling will be at the expense of the department undertaking the work. To advise contractors of the presence of all ACM prior to commencing the work. To be responsible for all asbestos work (Type 1, 2, 3, 4) performed by external individuals contracted to do the work, and to ensure that all such work is conducted in accordance with the Asbestos Management Program by regular monitoring of the progress of the work and regular site inspections. Ensure that the CSST is notified of all Type 4 operations before the work commences. To advise the asbestos program manager of all Type 2, 3, 4 asbestos work for which he/she is responsible by filling out the Asbestos permit form. See Appendix B. Ensure that asbestos removal be carried out by Contractors who have demonstrated competency in this field.. When ACM is not being removed as part of the project, Project Managers must advise Contractors of the presence of ACM near the work to be carried out. When asbestos removal is part of the project, ensure that inspection/air monitoring reports are given to the Industrial Hygiene Manager in a timely manner. Ensure that new materials used in renovations comply with Quebec s definition of an asbestos containing material (0.1% or greater). Employees This section applies to any University employee who may disturb or come into contact with ACM, through their regular work activities. Employees have the following responsibilities: Prior to starting work, employees are responsible to determine if asbestos is present in or around the work to be carried out (by verifying with their supervisors or Environmental Health and Safety). Follow the asbestos procedures (as outlined in the present asbestos management program). Carefully plan and complete work to avoid damaging asbestos. Immediately report any suspected asbestos exposure or damaged asbestos in the work area to their supervisor. EHS-DOC-014 v.3 11
Attend required training necessary to perform work activities. Do not store materials against asbestos containing materials or damage asbestos while moving furniture or other objects. Do not eat, drink, smoke or store food in areas containing friable asbestos containing materials. Contractors Contractors have the following responsibilities: Must comply with the University s current Asbestos Management Program when working near ACM. Immediately report any suspected asbestos exposure or damaged asbestos in the work area to the Project Manager or Security. CSST At anytime, CSST inspectors may inspect areas on University premises that contain ACM, to ensure compliance with applicable regulations. An inspector may stop work or shut down a construction site if applicable regulations are not respected. May require results of air monitoring performed in areas recognized as high priority for removal (from the asbestos inventory). EHS-DOC-014 v.3 12

EHS-DOC-014 v.3 15
EMPLOYER OBLIGATIONS TYPE 1 (LOW RISK) WORK In low risk work areas, the employer must ensure that employees wear respirators that satisfy either of the following: 1. It is specified in the Guide des appareils de protection respiratoire utilisés au Québec, published by the Institut de recherche Robert-Sauvé en santé et en sécurité du travail. 2. The respirator is certified to be an FFP2 type in accordance with EN-149 Standard. The equipment shall be selected, adjusted, used and cared for in accordance with CSA Standard Z94.4-93. TYPE - 2 (MODERATE RISK) WORK See Appendix C for detailed Type 2 work procedures. On a construction site where moderate-risk work is being carried out, the employer must ensure that: 1. Any worker in the area must wear a reusable respirator fitted with a HEPA filter as specified in the Guide des appareils de protection respiratoire utilisés au Québec, published by the Institut de recherche Robert-Sauvé en santé et en sécurité du travail. This equipment shall be selected, adjusted, used and cared for in accordance with CSA Standard Z94.4-93. 2. Disposable clothing must be changed each day and used clothing disposed of at the end of every shift by sealing it in a yellow waste bag. 3. Workers may not wear or carry their clothing outside the work area or the clothes locker room. 4. During work to enclose friable asbestos material, the work area must be isolated with materials impervious to asbestos fibres. 5. When removing a false ceiling for gaining access to a work area where friable material containing asbestos is found, the work area must be isolated with materials impervious to asbestos fibres and the ventilation system must be protected from contamination. 6. A sign with the following specifications must be posted at the entrance to each work area; yellow in colour, 500mm x 350mm with block writing as specified below: ASBESTOS 50 mm DANGER 40 mm DO NOT BREATHE THE DUST 15mm PROTECTIVE EQUIPMENT COMPULSORY 15mm NO ADMITTANCE WITHOUT AUTHORIZATION 15mm EHS-DOC-014 v.3 16
INHALING ASBESTOS DUST MAY BE HARMFUL TO YOUR HEALTH 10mm TYPE - 3 (MODERATELY HIGH RISK) WORK An employer handling or removing friable materials containing asbestos whose volume of debris exceeds 0.03 cubic metres without exceeding 0.3 cubic metres, for each minor renovation or specific regular maintenance work, shall fulfill the following obligations: 1. The employer must ensure disposable protective clothing is made available. The respirator used is the same as is used for Type 2 work. 2. The employer must isolate the work area from the rest of the building and supply it with a ventilation system equipped with a HEPA filter. 3. The employer must put in place a procedure for decontaminating prior to leaving the work area: The work area is cleaned by a wetting procedure or with a HEPA vacuum. After removal of protective clothing, the respirator and protective hard-hat are cleaned by wetting. The employee washes parts of his/her body that were exposed to dust that may have contained asbestos. TYPE - 4 (HIGH RISK) WORK A University employee shall never carry out type 4 work. 1. Workers must wear a powered air purifying continuous-flow, half-face or full-face piece or a supplied air continuous-flow half or full face piece, if working with power tools not fitted with a HEPA vacuum dust collecting system or when working with asbestos materials (other than chrysotile) that has been thoroughly wetted. 2. When working with asbestos material, which cannot be wetted, workers must wear a continuous flow positive pressure respirator fitted with a hood rather than with a mask. 3. Before work begins, the contractor must, together with the employer concerned, identify in writing and make available to the workers: The equipment and tools necessary to carry out the work and the measures to be taken in order to install, use, maintain, protect and move them. The hazards associated with the work to be carried out. The health and safety measures to be taken in accordance with the work to be carried out. EHS-DOC-014 v.3 17
The types of asbestos and other contaminants, which may be encountered while performing the work. The individual and common devices and equipment to be used. The measures to be taken in case of emergency, which must include the location of emergency exits. 4. At least once a day the employer must take a reading of the concentration of airborne respirable asbestos fibres in the work area in accordance with section 13 of the Regulation Respecting the Quality of the Work Environment. Upon completion of the work, it is prohibited to dismantle the airtight enclosure or to remove the airtight drop-sheet before the concentration of airborne respirable fibres drops to less than 0.01 f/cc air. 5. Other measures to be taken by the employer even when using an outside contractor to perform asbestos work include isolation of the work area to prevent building contamination, which can be achieved by the following: At the beginning and end of each shift, ensure that the airtight containment is in good condition. Air vents of the building ventilation system must be sealed off from the work area before the work begins and kept sealed during the work. Materials containing asbestos must be wetted before and during removal work unless this procedure constitutes a danger, which cannot be eliminated by another means. A locker area must be provided in a separate room and a shower located between the locker room and the work area must be provided. The work area and work clothes locker room must be sealed from the rest of the building with an airtight enclosure, which must have exhaust ventilation equipped with a HEPA filter. The ventilation system must provide at least 4 air exchanges per hour and put the area under a negative pressure between 0.001 and 0.004 KPa. EHS-DOC-014 v.3 18
SPECIFICATIONS FOR CONSULTANTS MONITORING FOR HIGH RISK ASBESTOS REMOVAL The minimum requirements for inspections and air monitoring for high-risk sites are outlined in the Safety Code for the Construction Industry (S-2.1, r.6). At Concordia, the consultants performing the air monitoring and inspections of the site must abide by the following procedures: 1. A thorough inspection must be performed once the enclosure is constructed, prior to the start of any contaminated work. This also includes a background air sample. No work can begin until the consultant has given their approval. 2. Daily air monitoring (to be analysed by PCM) must be performed during contaminated work both inside and outside the enclosure. 3. Daily inspections of the work site (during contaminated work) must be performed. This includes that the enclosures are in good condition; the negative pressure is adequate (between 0.001 and 0.004 Kpa) as well as ensuring that the proper work practices (outlined in the construction code) are carried out by the contractors performing the removal. If any of these conditions are not met, the consultant may cease work until the repairs or modifications are complete. 4. Daily inspection reports must be submitted before the start of the next workday and must include the results of the air monitoring. These reports must be given to the Concordia Project Manager and the asbestos program manager. 5. Upon completion of work, it is prohibited to dismantle the airtight enclosure until a final visual inspection is performed and a final clearance test is taken and analysed by PCM. The report from the final clearance test must also be submitted as soon as possible after the clearance test to the aforementioned persons. The air concentration of airborne respirable asbestos must be less than 0.01 fibres per cubic centimeter of air. A total of 5000 6000 litres of air must be sampled. If, at any time, the University Community is at risk due to the work being performed, the asbestos program manager has the right to halt the work performed by the contractor until such time as the situation is rectified. Note: These specifications are those that are adopted whenever a high-risk asbestos removal is performed through Project Management Services. The same procedures apply regardless of which department is contracting the work. Environmental Health and Safety (EHS) will ensure that daily inspection and air monitoring reports are made available to the Central Advisory Health and Safety Committee as well as Area Health and Safety Committees, if requested. EHS-DOC-014 v.3 19
PERSONAL PROTECTION Respirator Protection The regulations state that only respirators specified in the Guide des appareils de protection respiratoire utilisés au Québec, published by the Institut de recherche Robert-Sauvé en santé et en sécurité du travail are required for all levels of asbestos work. Respirators must be selected, fitted, used and maintained according to the CSA standard Z94.4-93. The requirements of respirator protection are as follows: Only half-face and full-face HEPA respirators are approved for all types of asbestos work. Respirators approved for asbestos exposure are required for low and moderate risk work. The selection of approved respirators, suitable for the hazard to which the worker is exposed is only one aspect of a complete respiratory protection program. Other elements include written operating procedures for respirator use; outlining personal responsibilities for respirator cleaning, storage and repair; training in proper respirator use and limitations; respirator fit testing; respirator cleaning and care and work site supervision. Proper respiratory protection is an integral component of all custodial and maintenance activities involving potential exposure to asbestos. When in doubt about exposure during a work operation, custodial and maintenance workers should be provided with respiratory protection. Protective Clothing In addition to the use of respirators, some procedures require workers to wear protective clothing. Usually, protective clothing is disposable and consists of coveralls, a head cover and foot covers made of a synthetic fabric that does not allow fibres to pass through. This type of clothing prevents worker s regular clothing from becoming contaminated with asbestos fibres. Contaminated clothing should not be taken home, as this might pose a risk to the worker s family members. It is important that workers be properly trained in the use, removal and disposal or protective clothing after use. WASTE REMOVAL Procedures for handling dust and waste containing asbestos after clean up or removal should be performed at regular and frequent intervals as the work proceeds. The following procedures should be practised. All ACM waste should be removed rapidly from the workplace All waste should be placed in a sealed plastic bag or barrel A label must be placed on the container indicating the following: - MATERIAL CONTAINS ASBESTOS EHS-DOC-014 v.3 20
- TOXIC BY INHALATION - KEEP CONTAINER TIGHTLY CLOSED - DO NOT BREATHE THE DUST EDUCATION/TRAINING The control of asbestos exposure can be achieved by following the procedures prescribed by the regulations. However, these procedures are only as effective as the person carrying them out. It is therefore essential that before a worker undertakes work liable to emit asbestos dust, he/she is trained and informed of the risks, prevention methods and safe working methods. The training and information program is outlined in the Quebec Safety Code for the Construction Industry c.s-2.1, r.6. Different levels of training may be necessary for different groups of workers. Three levels may be identified: Level 1: Awareness Training This training is for any employee, who during the course of their work, may come into contact with ACM or may contract work near ACM. Topics should include: The employer s general obligations Health effects of asbestos The standards applicable and the sampling to be carried out The worker s rights and obligations Locations of ACM in buildings Recognition of ACM damage and deterioration Individual and common protective devices and equipment The tasks to be carried out and the equipment and tools to be used Safe working methods and procedures Prevention and verification methods Level 2: Special Training This training is for maintenance workers involved in general maintenance and asbestos material repair tasks and for any worker whose duties include having to access ceiling space where friable asbestos containing material is present. Specific examples include: repair or removal of a small section of damaged thermal insulation, removal of ceiling tiles (constructing an enclosure), or plumbers removing piping. The level of training usually involves more detailed discussions of the topics included in level 1 training as well as the following: Asbestos regulations Descriptions of the proper methods of handling ACM, including waste handling and disposal EHS-DOC-014 v.3 21
Respirator use, care and fit testing Protective clothing use and handling Hands-on exercises for techniques such as glove bag work and HEPA vacuum use and maintenance Appropriate and proper worker decontamination procedures Level 3: Abatement Worker Training This applies to workers who may conduct asbestos abatement. For example, conducting a removal job, or encapsulating surface ACM. This work involves direct, intentional contact with ACM. Outside contractors will perform this work; thus, training for level 3 is not a priority for this program and is the responsibility of the contractor. Frequency of training All new employees must be trained as soon as possible. Supervisors are responsible for ensuring that employees, who have not been trained, do not disturb or come in contact with ACM. All employees must receive refresher courses every 2 years. PERIODIC INSPECTION AND AIR MONITORING A visual inspection of all ACM will be conducted at regular intervals as part of the asbestos management program. Combined with ongoing reports of changes in the condition of the ACM made by maintenance workers, the re-inspection should help ensure that any ACM damage or deterioration will be detected and corrective action taken. The buildings must be re-inspected by a qualified individual, as determined by the asbestos program manager, once every 2 years to reassess the condition of the ACM. A routine check every year to monitor the condition of the ACM can be carried out by trained maintenance personnel. If any modifications are made to Concordia buildings, re-inspection should follow immediately. Copies of these inspections reports shall be kept at Environmental Health and Safety. Through re-inspection, it is possible to determine both the relative degree of damage and assess the likelihood of future fibre releases. The use of visual records (photographs) of the ACM over time can be of great value during re-inspections. Environmental Health and Safety shall conduct air monitoring of areas identified as being high risk (i.e. potential for employee exposure is high) annually. A list of the current areas being monitored can be found in Appendix D, along with air monitoring procedures. These areas will have to be reassessed after visual inspections are carried out. EHS-DOC-014 v.3 22
RECORD KEEPING All the asbestos management documents should be stored in permanent files. These include: Survey reports, including results of bulk sample analysis Notification statements Documentation of worker training Inspection and air monitoring reports Periodic reassessment reports Copies will be made available to any building occupant upon request.

EHS-DOC-014 v.3 28
APPENDIX C: MODERATE RISK WORK PROCEDURES FOR ASBESTOS CONTAINING MATERIAL These procedures are to be followed by maintenance staff or contract persons performing the following work on friable asbestos materials: 1. Removal of any part of a false ceiling, if ACM fireproofing or mechanical insulation is present. Note: High-risk work procedures are required if the amount of debris above the ceiling tile is greater than 0.03 m 3. To determine the level of risk, an enclosure must be built using moderate risk work procedures. The supervisor or employee should gently lift one side of the tile or access panel, to inspect for asbestos debris and determine the amount, if any. High-risk work shall not be undertaken by any University employee. The area must first be cleaned by an outside contractor; after which employees can employ moderate work procedures to perform the necessary work. 2. The manipulation or removal of friable materials containing asbestos where the volume of debris does not exceed 0.03 cubic meters for each minor renovation or regular work specific to the area. 3. Enclosure of friable material containing asbestos except by the sprayed application of a sealant. 4. Removal of friable asbestos material (chrysotile only) where the work area can be sealed from the workers breathing area such as work in a glove bag for the removal of pipe lagging. 5. Removal of vinyl sheet flooring with an asbestos-containing backing felt. Equipment Equipment required for work must be on site before proceeding. Vacuum: A HEPA filter vacuum, equipped with brushes, fittings, etc. Personal protective equipment: o Workers within the work area shall wear approved respirators. o Respirators and filters will be provided by the employer, and individually assigned to workers. o Respirators shall be a half-face piece respirator with high efficiency (HEPA) filters. o Respirators must be kept in position throughout the entire time the worker is in the area of the work from the first disturbance of the ceiling tile or asbestos material until the final cleaning of the area and bagging of waste is complete. o Filters must be changed after 24-hours of wear, or sooner if breathing resistance increases. EHS-DOC-014 v.3 29
o Employees must have been fit-tested prior to any work. Fit testing is only required once to determine the size of the respirator for the employee. o No person using a respirator shall have facial hair that affects the seal between the respirator and the face. o All workers shall wear disposable coveralls (Tyvek) with attached elasticised hood. Coveralls should be worn with the hood in place at all times. o Coveralls may be vacuumed or wet wiped clean for re-use, for a maximum of 8 hours cumulative wear. Suit and head cover shall remain in place until worker leaves work area or the enclosure is dismantled. o Boot covers or dedicated boots are required if footwear cannot be effectively cleaned by wet wiping or vacuuming. Other equipment: o Plastic sheeting (6mm polyethylene) - to erect a total enclosure or to serve as drop sheet o Wood framing or clips to support polyethylene sheeting, as appropriate to work area o Tape to fasten plastic enclosure to ceiling or to tape drop sheet to floor o Labelled asbestos waste bag (6mm) for all asbestos waste, disposable suit, plastic sheeting for disposal, etc. o Pump sprayer containing amended water o Asbestos warning signs o Equipment necessary to perform work in question Other Protective Measures Do not eat, drink or smoke in the work area. On completing clean up of work area, use vacuum or wet cloth to clean hands, face, respirator and boots. Remove protective equipment and proceed to nearest washroom to wash exposed skin on hands and face. Scheduling of Work Ideally, work should be scheduled when occupants are absent. If work above ceiling is required on an emergency basis when area is occupied, have Facilities supervisor or Security advise occupants to vacate area until work is complete and clearance is given to return. EHS-DOC-014 v.3 30
Preparation Before undertaking any moderate risk work, a copy of a signed and approved Asbestos work permit must be obtained from the Asbestos Program Manager (Environmental Health and Safety). If possible, shut down ventilation systems to and from the work area. Seal over all ventilation openings, diffusers, grilles, etc., with plastic sheets. Where practical, clear areas of movable furnishings or equipment. This should include anything that occupants may wish to use during work periods. Any furnishings or equipment not removed shall be adequately covered and sealed using 6mm polyethylene and tape. The intent of the protection is to provide an airtight envelope to protect the articles from airborne dust or splashed debris. Post signs or barrier tape to indicate asbestos hazard and requirement for protective clothing for anyone entering the space. For small rooms, cover walls with plastic such that the complete room becomes the work area. For larger rooms, erect an enclosure constructed of 6 mm polyethylene of suitable dimensions to enclose the work area and scaffolds and ladders required to gain access. If a suspended ceiling is present, the enclosure shall extend to the ceiling line. The enclosure shall be as airtight as conditions permit including the provision of a double overlapping flap at the entrance. If the floor requires protection (ex. carpeted floor), the floor of the work area shall be a layer of 6 mm polyethylene sealed to the plastic walls of the enclosure. Don protective clothing and respirator prior to removing ceiling tiles or disturbing pipe jacketing or ACM. Execution To remove fireproofing or textured plaster, saturate using amended water solution, by use of a pump sprayer. Do not remove the asbestos material until the material is thoroughly wetted to the substrate. Do not use water where electrical hazards exist. To remove pipe insulation, first wet any area of damage, then carefully cut jacket. Keep insulation surface wetted by mist of water with wetting agent. Remove insulation in large sections and place immediately in disposal bag. After all large pieces have been removed, saturate debris on mechanical equipment and clean all exposed surfaces with abrasive pads, sponges, cloths etc. To repair pipe insulation, mist any exposed insulation to wet surface and apply lagging paint and canvas or PVC jacketing as required. For removal of suspended ceiling tiles (where fallen asbestos exists on top of tiles by inspection or prior knowledge), remove the first tile carefully and vacuum all surfaces. Vacuum the upper surface of each subsequent tile prior to removal. EHS-DOC-014 v.3 31
Store tiles in the work area. Remove dust and loose friable material likely to be disturbed in the process of doing the work, with a HEPA vacuum or by damp wiping. When asbestos material is removed, all pieces should be placed directly into 6mm polyethylene bags as they are removed. Avoid dropping material to the floor wherever possible. After bulk removal is complete, wet wash the exposed surface. Frequently, and at regular intervals during the work, clean up dust and waste in the work area by wet mopping, placing in disposal bags, or by HEPA vacuuming. After completion of removal, seal exposed ends of fireproofing, texture plaster, or mechanical insulation with heavy layer of encapsulating sealer. Apply sealer coat to surfaces from which asbestos material was removed. At completion of work, decontaminate equipment, tools and materials used in the work area by wet cleaning or HEPA vacuum. Dispose of drop sheets and enclosures by wetting the polyethylene, then folding into disposal bags. Do not reuse drop sheets. Before leaving work area, decontaminate shoes and protective clothing by using HEPA vacuum or damp wiping. Dispose of protective clothing in labelled bags. Workers shall vacuum all exposed skin, suit and respirator, and proceed to nearest washroom to wash hands and face. Removal of Asbestos-Containing Sheet Flooring Remove binding strips or other restrictive mouldings. Workers shall wear airpurifying respirator fitted with high efficiency filter, and coveralls at all times. Make series of cuts 100 mm to 200 mm (4 to 8 ) apart through top layers and about halfway through felt backing, parallel to wall. Start at end of room furthest from door and pry up corner strip, separating top sheet from backing layer. Pull top layer back upon itself slowly and evenly, and half backing and top layers should pull free. After it is removed, roll up strip face out into tight roll, tape or tie securely, and place into asbestos waste receptor. Wet the asbestos felt underlay remaining on floor as soon as exposed. Continue with successive strips. Avoid walking on exposed asbestos felt. Seal asbestos waste receptors when filled. Remove maximum of three strips before wet scraping exposed felt underlay. Remove remaining adhered underlay by wet scraping. Soak area with water applied by sprayer. Allow water to penetrate felt. Scrape off remaining material. Maintain material wet by applying more water. Place scrapings in asbestos waste receptor. EHS-DOC-014 v.3 32
Continue this procedure alternately removing top sheets and then wet scraping felt, three strips at a time. Be careful not to walk on stripped floor. When whole floor has been cleaned of asbestos felt, allow it to dry and vacuum up any dirt with a HEPA vacuum or wet mop. Do not dry sweep. Dispose of the mop head as contaminated waste. Thoroughly clean tools and equipment with a damp cloth before being put back into regular service. Dispose of cloth as contaminated waste. Waste Transport and Disposal Place waste into asbestos labelled disposal bag, seal with tape, clean the bag, and place into a second clean bag, also to be sealed with tape. Use a barrel, fibre drum, or cardboard or wooden box in place of the second bag when the asbestos waste material is likely to tear the inner bag. Seal the rigid outer container. Provide storage area for holding minor amounts of asbestos waste in sealed containers. Containers shall be labelled and assigned exclusively for asbestos waste. When waste is removed from site, collect copies of the waste transportation document from the disposal firm. For work performed by a contractor, the contractor will complete and transfer copies of a waste transportation document, on behalf of Concordia University. Waste generated by Concordia personnel will be stored in the chemical waste room on the 13 th floor of the Hall Building. EHS-DOC-014 v.3 33
