7 COPE AND PURPOSE This manual applies to all personnel at the Sarnia Refinery. References in this document to Personnel include Suncor employees, contractors, consultants and agents of Suncor. This manual may be followed for Unit Shut Downs, Turnarounds or Modular Outages. When requested to follow this manual a review will be done to determine if this strategy can safely be applied. If there is any doubt, the Hazardous Energy Control Manual must be followed. The purpose of this manual is to describe how hazardous energy is going to be isolated and control without using the Hazardous Energy Control Manual for Unit Shut Downs, Turnaround or Modular Outages. Turnaround Energy Isolation incorporates Battery Limit Isolation in conjunction with complete supporting documentation to eliminate and control Hazardous Energy for an entire Unit or Complex. Implementing this manual allows operations to eliminate the requirement for the Safe Work Permit Issuer and Receiver to tour each isolation point for a particular Safe Work Permit within the boundaries of the Turnaround Energy Isolation and the equipment being worked on is not deemed live or on the exceptions list. The Safe Work Permit Receivers are no longer required to lock out each individual equipment they are working on if within the Turnaround Energy Isolation Plan, since we are isolating a unit/area free of all energy and walk downs /lockouts/signoffs are being done at a Supervisory level. This manual applies only to Hazardous Energy Control and all other Standards and Work Practices must be followed during the use of this manual ZMN-HMSAFESA of 31 Rev #4

Execution Phase Implementation of the Turnaround Energy Isolation Plan for Unit Shut Down, Turnaround or Modular Outage. Approval Phase Verification that all of the conditions of the Turnaround Energy Isolation Plan have been completed and signed off that Unit Shut Down, Turnaround or Modular Outage is now under Turnaround Energy Isolation 4000-ZMN-HMSAFESA of 31 Rev #4

14 3.0: Definitions continued Control Phase Auditing to ensure the conditions of the Turnaround Energy Isolation Plans are still in place during Unit Shut Down, Turnaround or Modular Outage. If deviations to these plans are found Turnaround Energy Isolation will be reviewed and possible terminated until deviations are addressed. Energy Removal List A list of every Hazardous Energy Source that will be removed and controlled from a Unit/area for the duration of the Unit Shut Down, Turnaround or Modular Outage that is under Turnaround Energy Isolation. The list will have reference documentation and the method to which it will be controlled. (I.e. Process Battery Limit Blank List, 600 volt Electricity etc.) Exception List A list of Hazardous Energy Sources within the defined Unit or Complex that must be kept in service during the Unit Shut Down, Turnaround or Modular Outage. Each Hazardous Energy Source must list a valid agreed to reason for remaining in service during Unit Shut Down, Turnaround or Modular Outage well under Turnaround Energy Isolation and the method that it will be controlled. (i.e. Instrument Air) Live Equipment List A list of Equipment and/or Piping Systems that will remain in service during Unit Shut Down, Turnaround or Modular Outage well under Turnaround Energy Isolation. These Systems have no involvement or connection whatsoever to the equipment being worked on for the turnaround. (i.e. Main Flare Header) Turnaround Energy isolation Board A board to display and control the Energy Isolation Lock Rings that will be created for the Unit Shut Down, Turnaround or Modular Outage well under Turnaround Energy Isolation ZMN-HMSAFESA of 31 Rev #4

15 3.0: Definitions continued Contractor Initials Form This is a document that will allow Contractors to work in a unit/area under Turnaround Energy Isolation without applying an actual lock. The supervisor for each contractor will have to initial the Contractor Initials Form when working in the unit/area under Turnaround Energy Isolation and initial off when they are completely done their work in the unit/area for the duration of the Unit Shut Down, Turnaround or Modular Outage. At no time can Turnaround Energy Isolation be removed well a contractor is signed on the Contractor Initials Form for that specific unit/area during a Unit Shut Down, Turnaround or Modular Outage. NOTE Refer to HEC Manual for additional Definitions ZMN-HMSAFESA of 31 Rev #4

17 4.0 PREPARATION PHASE The following will cover how to create a Turnaround Energy Isolation Book. Each Unit/Area declaring Turnaround Energy Isolation will have to complete this procedure separately. Forms to create the turnaround energy isolation book can be found in the appendixes of this manual. With use of the appendixes it will be documented that only the specified Unit/Area will be considered under Turnaround Energy Isolation. NOTE It is your responsibility as a Field (Console) Operator to read and understand all procedures. For a scheduled shutdown or start-up the Field Operator will do a walk through the Unit prior to starting the procedure and familiarize yourself with all unit isolations, low point drains, N 2 connections for purging, steam connections for purging and unit blank locations. Any changes that may occur to any of the steps of a procedure MUST be recorded and approved on the printed procedure so the procedure can be updated in Livelink for future use. Changes/ Updates table is for any problems that are encountered during the execution of the procedure. The completed procedure MUST be returned to the Operations Coordinator. STEPS 1 Review and Revise Process Battery Limit Blank List for the unit or area. 2 Review and Revise Utility Battery Limit Blank List for the unit or area. 2 Create Energy Isolation Plans and documents required for Process Battery Limit Blank locations. 4 Create Energy Isolation Plans and documents required for Utility Battery Limit Blank locations. 5 Identify all other Energy Sources to be removed and create Energy Isolation Plan documents for these Energy Sources on the Energy Removal List. Identify reference documentation and the method of isolation for each energy source ZMN-HMSAFESA of 31 Rev #4

18 4.0: Preparation Phase continued STEPS 6 Identify all Energy Sources that are Exceptions and create Energy Isolations Plan documents for Exceptions List if needed. Identify reason for exception and the method of control. 7 Identify all Live Equipment and place on the Live Equipment List. 8 Place all documentation, (Battery Limit Blank Lists / EIP), (Energy Sources / EIP) (Exceptions List / EIP) and (Live Equipment List) in the Turnaround Energy Isolation Book 9 Document the EIP using P&ID s for all of the main process utility related blank points that make up the TA EIP. Note that the P&ID will document final installed TA status EIP. Each intermediate EIP that is required to be established to facilitate the installation/removal of the blanks will not be documented on the P&ID because they fall under the maintenance hazardous energy control. The mechanical contractor will be provided with the drawing to allow for confirmation of the work scope within the EIP and to facilitate a review prior to the establishment of the energy isolation envelope. 10 Create a Master Energy Isolation Plan for the Turnaround Energy Isolation Book referencing the documents in the Turnaround Energy Isolation Book. Place this Master Energy Isolation Plan on the front cover of the Turnaround Energy Isolation Book. 11 Identify the Turnaround Energy Isolation Approval Committee and present the Turnaround Energy Isolation Book and documentation for review and approval. 13 Have each Energy Isolation Plan reviewed and signed off by reviewer. (OM, OC, MC, SS) 14 Identify systems on the Live Equipment List in the Unit area with identification/signage if at all possible ZMN-HMSAFESA of 31 Rev #4

19 5.0 EXECUTION PHASE The HEC manual should be reference when completing Energy Isolation Plans during the Execution Phase. Part 1 - Process Battery Limit Blank Installation STEPS 1 Verify that the Energy Isolation Plan for each individual Process Battery Limit Blank location has been created, reviewed and signed off by reviewer. 2 Operation will isolate, tag (adding name and date) and lock (with a yellow lock) all valves on the Energy Isolation Plan specific to each Process Battery Limit Blank location. 2 Take the keys from the yellow locks and place them on a lock ring. The lock ring will be locked (with a red operations lock) and tagged (with blank number and description of blank) on the Turnaround Energy Isolation Board. Each device will be signed off on the Energy Isolation Plan that isolation has been established 4 After all isolation devices on the EIP for each specific Process Battery Limit Blank location have been isolated, tagged and locked, sign off that isolation has been established. 5 Maintenance will add a permit lock (blue lock) to the lock ring on the Turnaround Energy Isolation Board for the blank they will be installing. This will be done for every blank location on the Process Battery Limit Blank List. NOTE When creating Energy Isolation Plan s for Process/Utility Battery Limit Blanks, multiple blanks may be installed under the same EIP if needed. When permitting Process/Utility Battery Limit Blanks, multiple blanks may be installed on the same permit as long as permit conditions are the same for each blank. Be aware that normal procedures for preparing a blank location must still be followed. 6 Maintenance can now install Process Battery Limit Blanks ZMN-HMSAFESA of 31 Rev #4

20 5.0: Execution Phase continued 7 After blanks have been installed and signed off by maintenance, have the blue permit locks removed from the Turnaround Energy Isolation Board. 8 Operations to verify that the Process Battery Limit Blanks have been installed in the correct location and add a green Blanks Installed Tag to the lock ring. 9 Commence unlocking and opening isolation valves required to perform safing procedures. (Battery Limit Isolation Valve will remain closed and locked) 10 Sign off EIP that 1 st Isolation has been removed for each necessary device on the Energy Isolation Plan specific to the Process Battery Limit Blank location. WARNING The Unit or Complex covered by the installation of the Process Battery Limit Blanks is now ready for additional Safing Procedures. Turnaround Energy Isolation has not yet been satisfied therefore the normal permitting process will still be in effect. Unit Safing Procedures must be complete before the remainder of this Procedure is executed. NOTE If Safing Procedure are not going to be used for specific Unit Shut Down, Turnaround or Modular Outage you may install all battery limit blanks at the same period and isolate all energy sources immediately following blank installation. Part 2 - Utilities Battery Limit Blank Installation NOTE Utilities that are needed to perform safing procedures will be left in-service. Once procedures are complete Utility Battery Limit Blanks can be installed. Individual EIP s are not needed for Utility Battery Limit Blanks, once all utility isolation battery limit valves have been isolated and process battery limit blanks have been installed. This provides zero energy in the unit or area reference the Master Process Battery Limit Blank List on the Utility Energy Isolation Plan. STEPS 1 Verify that the Energy Isolation Plan for Utility Battery Limit Blanks has been created, reviewed and signed off by reviewer. 2 Operation will isolate, tag (adding name and date) and lock (with a yellow lock) all valves on the Energy Isolation Plan specific to each Utility Battery Limit Blank location ZMN-HMSAFESA of 31 Rev #4

21 5.0: Execution Phase continued 3 Take the keys from the yellow locks and place them on a lock ring. The lock ring will be locked (with a red operations lock) and tagged (with blank number and description of blank) on the Turnaround Energy Isolation Board. Each device will be signed off on the Energy Isolation Plan that isolation has been established. 4 After all isolation devices on the EIP for each specific Utility Battery Limit Blank location have been isolated, tagged and locked, sign off that isolation has been established on the EIP. 5 Maintenance will add a permit lock (blue lock) to the lock ring on the Turnaround Energy Isolation Board for the Utility Battery Limit Blanks. 6 Maintenance can now install Utility Battery Limit Blanks. 7 After blanks have been installed and signed off by maintenance, have the blue permit locks removed from the Turnaround Energy Isolation Board. 8 Operations to verify that the Utility Battery Limit Blanks have been installed in the correct locations, add DO NOT OPERATE tags referencing the Master EIP number and sign them off on the Master Utility Battery Limit Blank List. Add a green Blanks Installed Tag to the lock ring. Part 3 - Additional Energy Source Isolation NOTE There may be multiple Energy Sources that will be identified on the Energy Removal List to establish Turnaround Energy Isolation. This section describes the procedure that will be followed for isolating and documenting these Additional Energy Sources. Each Energy Source STEPS is unique but the procedure and documentation to be follow will be the same. 1 Verify that the Energy Isolation Plan for each individual Additional Energy Source has been created, reviewed, and signed off by reviewer NOTE If Additional Energy Source needs to be isolated by a specific trade or personnel they must be contacted at this time. (i.e. Electricians if electrical to be isolated is above 600 volts) 2 Operations will isolate, tag (adding name and date) and lock (with a yellow lock), all devices on the EIP specific to each Additional Energy Source. Electricians will isolate 2400 V and higher. 3 Collect all keys from the yellow locks and place on a lock ring. 4 Lock (with a red operations lock) the lock ring on the Turnaround Energy Isolation Board 4000-ZMN-HMSAFESA of 31 Rev #4

22 5.0: Execution Phase continued and tag with the information from the EIP. Sign off plan once isolation has been established. 5 The Primary Maintenance Contractor/TAMS will add a supervisory lock (Green Lock) to the lock ring on the Turnaround Energy Isolation Board for each Additional Energy Source. NOTE There may be multiple Maintenance Contractors working in the area under Turnaround Energy Isolation. These Contractors will have to sign on to the T/A Energy Isolation Plan Contractor Initials Form (Info in section 8.0). Part 4 - Exception List Energy Source Isolation NOTE For the Exceptions List, if the Method of Control requires the use of an Energy Isolation Plan STEPS continue on with section 5.0, if not list items and their criteria on the Exceptions List 1 Verify that the Energy Isolation Plans for items on the Exception List have been created, reviewed and signed off by reviewer. 2 Operations will isolate, tag (adding name and date) and lock (with a yellow lock), all devices on the EIP specific to each Exception. 3 Collect all keys from the yellow locks and place on a lock ring. 4 Lock (with a red operations lock) the lock ring on the Turnaround Energy Isolation Board and tag with the information from the EIP. Sign off plan once isolation has been established. 5 The Primary Maintenance Contractor/TAMS will add a supervisory lock (Green Lock) to the lock ring on the Turnaround Energy Isolation Board. 6 Complete this for all Exceptions on the Exceptions List that require and EIP. Part 5 - Master Energy Isolation Plan Sign Off STEPS 1 When all documentation in the Turnaround Energy Isolation Book have been isolated and signed off. The Master Energy Isolation Plan for that area can now be completed and signed off. 2 Refer to the Master Energy Isolation Plan number when permitting work for the Unit Shut Down, Turnaround or Modular Outage under Turnaround Energy Isolation ZMN-HMSAFESA of 31 Rev #4

25 6.0 APPROVAL PHASE The following with be used to verification that all of the conditions of the Turnaround Energy Isolation Plan have been completed and signed off in the Turnaround Energy Isolation Book. Part 1 - Turnaround Energy Isolation STEPS 1 Turnaround Energy Isolation Approval Committee will review all documents (Energy Removal List, Exception List and Live Equipment List, Blank Lists and EIP s) in the Turnaround Energy Isolation Book to confirm all requirements have been completed and signed off. 2 The Committee will perform an audit of the EIP to confirm that all of the devices listed on the Master Energy Isolation Plan and supporting EIP s are in place as stated. The audit will consist of: 100% of the energy isolation devices that are used to lock out the additional (non-blanked) energy sources, will be field audited by an operations representative along with the primary mechanical contractor(s) representatives to confirm that they have been established. A field verification of at least 10% of the blanks that have been documented on a blank list with signatures from two independent departments where the blanks that make up the TA EIP have been identified on P&ID drawings. For example, a blank that has been installed by maintenance or a mechanical contractor and witnessed by an operator. The blank list has been signed off in accordance with the sites, by a representative from the department that installed the blank and by an operator that witnessed the installation of the blank. Audit the blank lists that makeup the TA status EIP to confirm that both sets of signatures are present. One signature is required by the contractor that installed the blank and one signature by the operator who witnessed and verified that the blank is installed and is located in the correct location. 3 The Committee will then sign off on the Turnaround Energy Isolation Approval Form that all requirements have been established and the unit/area can now declare Turnaround Energy Isolation ZMN-HMSAFESA of 31 Rev #4

26 6.0 Approval Phase continued WARNING Turnaround Energy Isolation cannot be declared without all of the required Signatures on Appendix D. 4 Attach a copy of Appendix D - Turnaround Energy Isolation Approval Form on the Display Boards at the Unit or Complex Battery Limits Part 2 - Contractor Initials Form Sign Off STEPS 1 A Contractor Initials Form must be filled out for each area that will be under Turnaround Energy Isolation. Each Contractor must be listed and the Contact Person for that Company ZMN-HMSAFESA of 31 Rev #4

27 6.0: Approval Phase continued 2 Once the Approval Committee has reviewed and signed off the Turnaround Energy Isolation Approval Form, the contractors can initial on the CIF for the area that they will be working in. 3 Place the Contractor Initials Form in the Turnaround Energy Isolation Book for each area. WARNING Once a contractor has Initialed onto the Contractor Initials Form the Supervisory Lock(s) cannot be removed until every Contractor has Initialed Off the Form. 4 Contractors will stay signed on to the CIF until all of their work is complete in that area for the duration of the Unit Shut Down, Turnaround or Modular Outage ZMN-HMSAFESA of 31 Rev #4

28

29 7.0 CONTROL PHASE During the Unit Shut Down, Turnaround or Modular Outage the Turnaround Energy Isolation Approval Committee will monitor the status of devices used to create Turnaround Energy Isolation. Part 1 Audits STEPS 1 Audits will be performed weekly by the Turnaround Energy Isolation Approval Committee with the use of Appendix F (Turnaround Energy Isolation Audit Form) 2 Fill out Appendix F by choosing 5 devices of isolation that were used to declare Turnaround Energy Isolation. 3 Identify these devices in the field and confirm that proper isolation is still in place. NOTE If any of the devices have been found not in compliance with the Turnaround Energy Isolation Book, Turnaround Energy Isolation will be re-assessed immediately. Appendix G (Turnaround Energy Isolation Review Form) must be completed at this point. 4 If all devices are in place, the Turnaround Energy Isolation Approval Committee will sign the Turnaround Energy Isolation Audit Form and place the form in the Turnaround Energy Isolation Book for reference Part 2 Review NOTE If a device on the Energy Removal List or Exception List must be altered or moved, Appendix F (Turnaround Energy Isolation Review Form) must be completed. STEPS 1 Identify the reason for device to be altered. (i.e. piping job needs battery limit blank to be removed) 4000-ZMN-HMSAFESA of 31 Rev #4

30 7.0: Control Phase continued 2 Determine how isolation will be guaranteed before the device can be altered. 3 Turnaround Energy Isolation Approval Committee will review and complete Appendix G (Turnaround Energy Isolation Review Form). They will sign off and place the Turnaround Energy Isolation Review Form in the Turnaround Energy Isolation Book for reference. Part 3 Testing STEPS 1 Hydro Static Testing will be noted on the Exceptions List. 2 While equipment is being tested, no other maintenance can be done on that specific equipment until testing is complete. 3 Signage will be displayed to identify that a test is in progress and will be removed once test is complete. Part 4 Permitting STEPS 1 When permitting any work that is covered under the Turnaround Energy Isolation envelope, operations will reference the Master Turnaround Energy Isolation Plan number on the permit for each particular unit/area. 2 The Master Turnaround Energy Isolation Plan number will be specific to each area covered by their designated Turnaround Energy Isolation Book ZMN-HMSAFESA of 31 Rev #4
