4 1. Purpose The (PTW) procedure defines the minimum requirements to provide a safe system of Work when plant is taken from service for breakdown, maintenance or capital work and when Work is not controlled as Pre-Approved Work at Seqwater operational sites. The system also provides a trigger for the use of other permits for high risk work (2nd Tier Permits) such as hot work, work at heights, confined spaces work, excavation, fault finding, HV, and grid mesh, handrail and flooring removal. This procedure is a documented system that provides a notification of intent and an approval process, to undertake a specific scope of Work. 2. Scope The PTW process forms part of the Site Access and Works Control System (SAWCS) and covers Seqwater employees, contractors and sub-contractor employees engaged in operational, maintenance, inspection, construction, commissioning, decommissioning or alteration activities, that are not controlled as Pre-Approved Work, carried out at Seqwater owned and operated sites. All principal contractors shall abide by this procedure or submit a Safety Management Plan for endorsement by the Seqwater Workplace Health and Safety and Environment Departments. Any submitted Safety Management Plan must, as a minimum, achieve the intent of this procedure. 3. Definitions TERM 2 nd Tier Permits 2 nd Tier Permit Authority Access Officer DEFINITION Any permit used at Seqwater owned and operated sites to manage specific High Risk hazards, e.g. hot work, work at heights, confined spaces work, excavation, fault finding, HV, and grid mesh, handrail and flooring removal. A Worker holding the appropriate licences, tickets and industry regulated competencies relevant to the 2nd tier task they are performing. They approve and issue the relevant 2nd Tier Permit. The officer in control of dams, natural areas, facilities or water treatment plants who is nominated to maintain the responsibilities of this procedure. The Access Officer in responsible for assessing and approving/rejecting access requests and PTW s. They must ensure the proposed work does not produce conflicts in operational and maintenance requirements for the site and identify area specific and process hazards that the Worker may not be aware of.

5 TERM Additional Isolator Applicant Break in work CIS De-isolation Equipment Identification Tag Emergency DEFINITION Isolations are discipline specific. Isolations and de-isolations must only be performed within the Workers training, qualifications and competency e.g. Only licensed electricians may perform electrical isolations within an electrical exclusion zone. As a result, Permit Recipients will require additional resources to carry out isolations when working with energy sources requiring multi discipline isolations. Additional Isolators work only under the direction of the Permit Recipient or the Pre-Approved Worker. Person applying for access and or PTW from the Access Officer. The Applicant may be requesting access on behalf of the Worker or requesting access for themselves and their work party. Any time a Permit Recipient or Permit User of a PTW needs to leave a job for any period of time other than for meal and ablution breaks. Corporate Information System The process of re-energising hazardous energy sources Equipment Identification Tags are used to formally identify equipment (in the field) and associate it to Pre-Approved Work or a particular PTW. Equipment Identification Tags are placed by the Pre-Approved Worker or Permit Recipient prior to the commencement of any work under the control of a PTW. Equipment Identification Tags should be removed by the Worker-in- Charge or Permit Recipient upon the completion of the task. Equipment Identification Tags are green in colour. An emergency is the sudden, unexpected, or impending situation that may cause injury, loss of life, damage to property, and/or interference with the normal activities of a worker or operations and which, therefore, requires immediate attention and remedial action. e.g. fire, flood, medical emergency. Sources of energy that have the potential to cause injury, property damage or impact on the integrity of water supply. These sources may include: Hazardous Energy HV Electrical energy Influx of water or liquids Material/substances under pressure High Voltage Rotating or moving parts Release of toxic or caustic substances Potential energy Document Number: PRO Version Date: 19/11/2012 Page: 5 of 23

6 TERM Isolation Instruction Inch and Test Isolation Point JSEA Level 3 Manager Operational Site Permit Board Permit Recipient DEFINITION A documented instruction on the isolations required to be performed in order to safely conduct tasks. It contains explicit instructions to: Identify isolation points Positively isolate Discharge stored energy Lock and Tag out Test for dead, prove for dead De-isolate Inch and Test The Isolation Instruction is developed by the Permit Recipient, and reviewed by the Access Officer prior to use. The process of functional testing of equipment during commissioning. The Inch and Test Program may require the partial or full de-isolation of equipment and is recorded on the Isolation Instruction. A point at which an Isolation Lock and Tag can be applied to effect positive isolation. Job Safety and Environmental Analysis Seqwater Managers directly responsible for the day to day operation of water production facilities and plant. Any Seqwater owned and/or operated site. A board consisting of a lockable compartment and document holder that also provides multiple lockout capability Permit Boards provide the security for keys from Isolation Locks used to positively isolate equipment. Permit boards are used for the retention and displaying of documents associated to the / Pre-Approved Work (PTW form, 2 nd Tier Permits, Isolation Instructions, Work Order, etc). Permit boards are a common personal lockout point for all Workers to apply their Personal Danger Locks and Tags, protecting themselves from hazardous energy. Permit Boards may also be used for Pre-Approved Work where there are multiple isolations and there is a need for Isolation Lock keys to be secured in a central location. Any worker formally trained and assessed competent to complete tasks and accept conditions listed on the. The Permit Recipient in charge of the Work. They are responsible for applying for access, coordinating the PTW and any isolations. Document Number: PRO Version Date: 19/11/2012 Page: 6 of 23

7 TERM Permit Recipient Tag PTW Permit User Positively Isolated Positive Isolation Hardware RTHA Second Person Shall Should Test for Dead, Prove for Dead Work Worker DEFINITION A white tag applied by a Permit Recipient (with their Personal Danger Tag) to their Personal Danger Lock identifying them as the recipient of the corresponding PTW. A formal document used to identify the controls to be implemented to provide a safe workplace and safe systems of work. Any worker who has been trained and assessed competent to complete the work tasks and works under the direct supervision of the Permit Recipient. A complete physical separation of energy sources preventing energy transmission using a current isolation switch, isolating valve or device. Equipment is not positively isolated if the energy can be activated by another means while isolated. The shrouds (hardware) used in the positive isolation of valves, fuses, circuit breakers, electric leads and plugs. Real Time Hazard Assessment. A documented hazard assessment, or infield review, performed at the intended place of work prior to a PTW being issued, or during tasks where there is a change in conditions. A person trained in and assessed as competent in the Energy Tag and Lockout Procedure and the SAWCS process. Isolations are always confirmed by a Second Person cross checking each isolation point including de-isolations and re-isolations as required for testing/inching and PTW cancellation. To be interpreted as mandatory. Used in an advisory or discretionary sense. The test conducted by a Permit Recipient/ Pre-Approved Worker to test for dead, Prove for Dead after attaching Isolation Locks and Tags to an isolation point. This process ensures that the plant and equipment cannot be started and is documented in the Isolation Instruction Any task that is conducted on an operational site outside of an administration, meeting or office environment. The term Work excludes courier drivers, mail delivery, waste collection, security personnel. A Seqwater employee or business partner authorised and inducted to carry out work at an operational site.

13 7. Hardware & Software 7.1 The hardware used in the PTW process includes: HARDWARE Book-fast 2nd Tier Permits Book-fast JSEA RTHA Cards Permit Boards Permit Recipient Tag Equipment Identification Tag Information Tag Isolation Lock and Tag Personal Danger Lock and Tag Out of Service Lock and Tag DESCRIPTION Written record of work approval Written record of 2 nd Tier activities Written record of job hazards and their controls Real Time Hazard Assessment record Secure Isolation Lock keys and associated paperwork Identifies the Permit Recipient on the Permit Board Identifies the equipment to be worked on Displays information relevant to the equipment Secures isolation points Secures isolation lock keys in the Permit Board and identifies Workers working on the PTW Identifies defective equipment and secures isolation keys in the Permit Board while there is a break in work In addition, a multitude of positive isolation hardware is available at operational sites. Further information on the listed hardware is available in the Energy Tag and Lockout Procedure. 8. Process 8.1 Application for a Work is generally planned in advance allowing appropriate time for the management of plant output to minimise disruption to services. To begin the process the Permit Recipient or Applicant acting on their behalf sends the request for Site Access and PTW via a MS Outlook Calendar Appointment addressed to the appropriate Access Officer at least 48 hours in advance of the planned start date, where possible by: 1. Searching the Access Officer Register (REG-00538) for the appropriate Access Officer 2. Generating a MS Outlook Calendar Appointment addressed to the appropriate Access Officer Document Number: PRO Version Date: 19/11/2012 Page: 13 of 23

14 3. The Appointment should contain the following information: a. A description of the work (may include Work Order Number) b. The location c. The time and duration for access d. A message containing relevant information for the Access Officer to approve your application, e.g. PTW. 4. Attach the required supporting documentation if available e.g. JSEA, Isolation Instruction etc and send the outlook meeting request If the Applicant/ Permit Recipient is unable to send an outlook meeting request they may use the Access Officer Group telephone number to contact the relevant Access Officer. The relevant information above must be provided verbally. If there is no JSEA and or Isolation Instruction, one must be drafted on arrival to site before a PTW Activation Number can be issued. 8.2 Call outs/ Breakdowns / Reactive Work In the case where work is unscheduled (i.e. a breakdown/callout), the PTW process must still be followed by the submission and review of a JSEA however: 1. The Access Officer may grant approval for access verbally via the call out and record it in the Access Log at a later date 2. Review of the JSEA may be accepted by the signature of the Access Officer on the JSEA and recorded in the Site Access Log at a later date 3. Approval and closure of the PTW may be granted by the signature of the Access Officer on the PTW and recorded in the Access Log at a later date 8.3 Approval for Work The Access Officer assesses the application by reviewing the JSEA and taking into account: 1. The type, priority and timing of the work. 2. Production and maintenance plans. 3. The items of plant and equipment that would require isolation and the impact this would have on operations. 4. Confirm with the Supervisor the training and competency of those nominated to conduct the work. 5. The impact of 2nd Tier Permits on operations. The Access Officer notifies the applicant of acceptance or rejection of the application Where a conflict with other works arises and or, there is a lack of information in the application, the Access Officer may reject the Application. Where a rejection occurs, the Access Officer identifies the issues with the Applicant and may suggest an appropriate re-scheduling time. 8.4 Arrival at Site Entrance Every Seqwater Operational Site will have a sign located at the entrance showing the Access Officers contact details, see below: Document Number: PRO Version Date: 19/11/2012 Page: 14 of 23

15 On arrival at the operational site entrance the Permit Recipient shall: 5. Contact the Access Officer to notify them of their arrival. Where there is limited phone coverage, contact shall be made with the Access Officer prior to arriving on site. 6. Where the access has not been pre-arranged the Permit Recipient must provide all the information required from 8.1 above and wait for the Access Officer to approve access. The Access Officer shall: 1. Where the Site Access has not been pre-arranged, assess the application for access following 8.1 above. 2. Confirm access approval for the Permit Recipient in the Access Log and allow access into the site for sign in (mandatory) and induction (if not previously). 8.5 Arrival on Site Once inside the Operational Site the Permit Recipient must: 1. Ensure they and the working party sign in; and complete the induction requirements if not previously inducted. 2. If there are no sign in facilities i.e. remote site, the Permit Recipient must inform the Access Officer of the date and time of arrival for inclusion in the Access Log. 3. Conduct an RTHA (Refer to GDE-00089) 4. Develop a JSEA (Refer to TEM-00013) for the Work if not already done 5. Develop an Isolation Instruction (Refer to TEM-00077) if not already done 6. Undertake a review of the JSEA with the Access Officer and implement any additional controls. Document Number: PRO Version Date: 19/11/2012 Page: 15 of 23

16 The Access Officer shall: 1. If there are no sign in facilities i.e. remote site, the Access Officer must enter the date and time of arrival in the Access Log. 2. Review the JSEA and Isolation Instruction with the Permit Recipient to: Ensure the proposed Work does not produce conflicts in operational and maintenance requirements for the site. Identify area specific and process hazards that the Worker may not be aware of (e.g. other workgroups in the area, chemical storage facilities, changed conditions, etc). Add any necessary controls to the JSEA. 3. Access to Work may be denied based on an inadequate JSEA, conflicting priorities, and or a lack of information in the application. 4. Where a rejection occurs, identify the issues with the Permit Recipient. This may include suggesting an appropriate re-scheduling time. 8.6 PTW Activation When the Permit Recipient is ready to have the PTW activated they carry out the following tasks: 1. Fill out the PTW 2. Review the JSEA with the work party 3. Fill out any 2nd Tier Permits as required 4. Confirm controls are in place for 2nd Tier permits if required 5. Attach the green Equipment Identification Tag to the equipment work is proposed for, where appropriate 6. Contact the Access Officer to request a signature or a PTW Activation number. A PTW can be activated by either the signature of the Access Officer or a PTW Activation Number. The PTW Activation Number is generated from the Access Log. The Access Officer must carry out the following tasks before activating the PTW: 1. Review the JSEA and check for work conflicts that impact or may be impacted upon by the work proposed under the PTW. 2. Confirm controls are in place for 2nd Tier permits if required. 3. Confirm there is an isolation Instruction if required. The Access Officer then signs the PTW or issues the PTW Activation Number and the Permit Recipient records the number on the PTW to confirm the permit is activated. If there are no Isolations required, the Permit Recipient locks their Personal Danger Lock and Tag and Permit Recipient Tag onto the Permit Board. 8.7 Undertaking Isolations Isolations are discipline specific. Isolations must only be performed within the Worker s discipline specific training, qualifications and competency. As a result, Permit Recipients will require Additional Isolators when working with energy sources requiring multi discipline isolations. Document Number: PRO Version Date: 19/11/2012 Page: 16 of 23

17 Additional Isolators work only under the direction of the Permit Recipient. If isolations are required, the Permit Recipient must undertake a RTHA for the isolations before any are performed. Then they must, carry them out personally, and or coordinate the isolations by following the Isolation Instruction explicitly to: 1. Identify the Isolation Points. 2. Where no effective isolation hardware exists they must submit a work request to install a suitable device and an alternative means of isolation shall be established until the issue can be rectified. 3. Isolate the energy source. 4. Discharge or release stored energy. 5. Lock and tag out the Isolation Points. 6. Sign the Isolation Tags and the relevant sections of the Isolation Instruction. 7. Have isolations checked by a Second Person and have that Worker initial the Isolation Tags and sign the relevant sections of the Isolation Instruction. 8. Test for dead, prove for dead. 9. Secures the Isolation Lock keys in the Permit Board. 10. Locks the Permit Board with their Personal Danger Lock, Tag and Recipient Tag. Once this is complete the energy sources are deemed Positively Isolated. The Permit Recipient then secures the PTW on the Permit Board with the JSEA, Isolation Instruction, 2nd Tier Permits and other relevant documents. Refer to the Energy Tag & Lockout Procedure (PRO-00014) for further explanation of positively Isolating energy sources. 8.8 Issuing 2nd Tier Permits 2nd Tier Permits are required for the following high risk work activities: Confined space work Hot work Trenching and excavation High voltage Fault finding Work at height Grid Mesh, Hand Rail and Flooring Removal If a 2nd Tier Permit is required the 2nd Tier Permit Authority must fill out the required permits and implement the appropriate controls as described in the JSEA for the work. 8.9 Carrying out Work Under an Activated Once all the controls are in place for the work as described in the JSEA the Permit Recipient ensures; 1. The Permit Users sign on to the PTW. 2. The Permit Users lock their personal danger tags and locks onto the Permit Board. 3. The work party carry out a RTHA for the work. Document Number: PRO Version Date: 19/11/2012 Page: 17 of 23

18 4. The Permit Recipient signs the PTW Acceptance section of the PTW form 5. The Permit Recipient signs the Permit User section of the PTW 6. The work party then proceed with the work. 7. If an emergency occurs during the course of the work, follow the steps outlined in the Appendix below Changes to the Work Under the If there is a change to the task and or work conditions after the PTW has commenced (e.g. an emergency, 2nd Tier Permit is required): 1. Work shall immediately cease. 2. The Permit Recipient will immediately contact the Access Officer and in consultation they will determine if the change alters the Scope of Work that the original PTW was issued under. Where the Scope of Work has changed a new PTW shall be obtained. Where there is no change in the Scope of Work but new hazards have been introduced to the job (i.e. 2nd Tier Permit), the JSEA must be reviewed and updated and additional controls implemented prior to the re-commencement of work Break in Work A break in work is any prolonged break in the work other than meal and ablution breaks. The most common example of a break in work is the end of a shift. When a break in work occurs the following takes place: 1. Permit Recipient leaves all isolations in place. 2. Permit Users remove their Personal Danger Locks and Tags from the Permit Board. 3. Permit Users sign off the PTW. 4. Permit Recipient places an Out of Service Lock and Tag onto the Permit Board, explaining the reason for the delay or break in work. 5. Permit Recipient removes his Personal Danger Lock, Tag and Recipient Tag from the Permit Board. 6. The Permit Board remains on site if break is less than one day if the break is longer than 24hrs the PTW board remains at the operational control room. 7. The key to the Out of Service Lock stays with the Permit Recipient if the break is not longer than 24hrs. 8. The key to the Out of Service Lock stays with the Supervisor if the break is longer than a day. For a break in work and a change of Permit Recipient refer to below Change of Permit Recipient From time to time a change in Permit Recipient may be required to complete work under a PTW. Changes to Permit Recipients may occur under the following conditions: Document Number: PRO Version Date: 19/11/2012 Page: 18 of 23

19 Change in Permit Recipient, no Break in Work: 1. Permit Recipient informs Access Officer of change. 2. New Permit Recipient signs onto PTW. 3. New Permit Recipient attaches their Personal Danger Lock and Tag and Permit Recipient Tag to the Permit Board. 4. Old Permit Recipient signs off PTW. 5.
