SAFETY PRACTICES MANUAL
Accident prevention and efficient operations go hand in hand; therefore, incorporating safe work practices in our day-to-day operation is essential to minimize accidents, injuries and job interruptions.
This manual provides safe guidelines for all employees to use in addressing the potential risks associated with each task when developing safe work methods. Guidelines specified are in accordance with governing regulations, standards, BP Canada requirements, and recommended good working practices. It will be necessary to incorporate these practices into the specific situations that will arise in each operation.
The manual covers many, but by no means all, of the jobs and situations encountered in our operations. Should situations arise which are not adequately covered in the manual, please bring it to the attention of your immediate supervisor.
The definition of a BP representative in this manual is taken to include employees, contractors, consultants, and service representatives who have the authority and are duly quali-fied to direct work on a the behalf of BP. A BP designate is an individual who has authority to direct a defined scope of work specified by the BP Representative. Safety is everyone’s responsibility.

Confined Space Entry
CONFINED SPACE ENTRY PRACTICE
1.0 Scope and Applicability
1.1 This practice applies to BP Canada Gas Performance Unit (CGPU) employees, contracted employees, contractors, and other visiting personnel doing work on CGPU premises and sites.
1.2 This practice provides guidelines for the development of site specific procedures to prevent injury to personnel by ensuring that an assessment of all known hazards, pre-job planning, and communications are done prior to and during work in confined spaces. 1.3 The purpose of this practice is to ensure that
all reasonable precautions will be taken to protect the safety of personnel who are or may be required to work in confined spaces.
2.0 Scope of Definitions
2.1 Confined Space:
A confined space means an enclosed or partially enclosed space that is not primarily designed or intended for human occupancy, except for the purposes of performing work, having restricted access or egress and which, due to its design, construction, location, atmosphere, the materials or substances in it, or other conditions, is or may become hazardous to a worker entering it, or does not have an easy means of escape for, or rescue of, a worker entering it. Examples:
2.1.1 Tanks, vessels, towers, heaters, silos, aerial coolers, bins, hoppers, tank cars, ventilation or exhaust ducts, sewers, underground utility tunnels or pipes, scale pits, sumps, vessel skirts, mud pits and cement and chemical storage tanks.
Confined Space Entry
2.1.2 An excavation is considered a confined space under certain circumstances, for example if there is limited access or egress or the quality of the atmosphere cannot be guaranteed. 2.1.3 A diked area could be considered a confined
space if it is more than 1.5m deep and the atmosphere cannot be guaranteed. 2.1.4 Tower or vessel skirts, under trailers with
skirts, false ceilings, because of restricted ac-cess and egress must be considered as confined space.
2.1.5 Others, such as pipe racks, utility doors, compressor fan housings and hoardings.
Confined Space Entry DETERMINATION OF CONFINED SPACE
2.2 Entry into a confined space is deemed to have occurred as soon as the plane of the entry point has been broken by a part of the body.
2.3 All BP Canada Gas Performance Unit CGPU sites must: • Identify and document all confined spaces • Label all entry points. Class 1 Confined Spaces labeled “Confined Space”, Class 2 & 3 Confined Spaces labeled “Confined Space – Permit Re-quired” • Identify and control all hazards prior to entry utilizing site specific procedures
NO NO NO
YES YES YES
Does the space now have or has it previously had contents that could be harmful? Is the space enclosed enough to contain a hazardous atmosphere or other physical h d? Is access/egress so restricted that emergency exit or rescue requires extra manpower or equipment? NOT A CONFINED SPACE
THIS IS A CONFINED SPACE
Class 1 – No Hazard A Confined Space in which there does not exist and is not likely to exist: x A hazardous gas,
vapour, dust or fumes x An oxygen content

and capped or blind flanged, “slip” or “pan-cake” blinds rated for full line operating pres-sure must be used. If a full-rated ASME blind cannot be accomplished, a safe process must be developed in close cooperation with site engineers. The ASME size and rating, as well as the MAWP (maximum allowable working pressure) must be permanently marked on the handle in such a manner that the information is visible when the blind is installed. 5.2.4 Blinds that do not meet engineering practices
and have not been marked accordingly will not be used.
5.2.5 A blind list will accompany the site specific job procedure for the confined space being entered.
Confined Space Entry as close to the confined space as practical. It
is acceptable to include a re-boiler, exchanger, etc., as part of the package for the Confined Space, providing that the entire system is tested in accordance with the following: •
Explosive gases or vapors: continuous monitor-ing is required where the atmosphere cannot be guaranteed. When gases lighter than air could be present, continuous monitoring of high points is required. When gases heavier than air could be present, continuous monitoring of low points is required
• NORM: Naturally Occurring Radioactive Mate-rials should be tested for, if known to exist in the stream
• Noise - All effort must be made to monitor, minimize and protect against

5.4.1 Appropriate personal protective equip-ment must be worn for the particular job as required (i.e. fire retardant clothing, gloves, boots, goggles, face shields, respiratory ap-paratus, safety harness and lifelines). 5.4.2 Prior to any confined space entry the con
trolled products that may be encountered in the confined space must be identified and the MSDS on these materials must read and understood.
5.4.3 Breathing apparatus is also required as standby equipment outside the confined space, to be used by personnel responding to emergency. 5.5 Emergency Rescue
5.5.1 A rescue plan must be completed, reviewed, documented and a copy must be on site prior to a confined space entry.
5.5.2 Rescue plans will be kept on file at the facility. Any equipment required to imple-ment the plan must be in place prior to the confined space entry. New plans will be developed only where a suitable plan does not already exist.
5.5.3 A competent safety standby person must be in attendance at the entrance during all phases of any confined space entry unless classified as a Class 1 confined space.
Confined Space Entry
5.6 Communication
5.6.1 A system of communication must be established and maintained, between the safety standby person and the person(s) in the confined space. This method must include at least two of the following:
• Simple voice • Visual contact • Radio equipment • Alarm horn

Energy Isolation
ENERGY ISOLATION PRACTICE (LOCK OUT – TAG OUT)
1.0 Scope and Applicability
1.1 This practice will be used if the unexpected energiza-tion or startup of machinery or equipment or the unexpected release of energy could result in health, safety, environmental or equipment damage losses. 1.2 This practice specifies minimum requirements for the
control of hazardous energy.
1.3 This practice applies to all BP Canada Gas Performance Unit (CGPU) employees, contracted employees, contractors and other visiting personnel doing work on CGPU premises and work sites. 1.4 This practice does not apply to hot tap operations
performed on pressurized pipelines, provided it can be demonstrated that: • Continuous service is essential • Shutdown of the system is impractical • CGPU accepted documented procedures are followed • Equipment is used that will provide proven, effective protection for employees 2.0 Scope of Definitions 2.1 Functional Area Manager – Operating Center Man-ager or Wells Manager or HSSE Manager. 2.2 Functional Team Lead – Area Foreman, Construc-tion Foreman, Wellsite Leader.
2.3 Area Authority – the person who is on-site or as-sociated with that site and is assigned single point accountability for that site. This person can be the operator in charge, a maintenance worker, a con-struction foreman or a wells foreman or designate. 2.4 “Authorized worker” is a person who applies the
energy isolation procedure and is deemed competent by the functional team leader or designate. 2.5
“Affected worker” is a person who works on equip-ment in which energy control procedures have been implemented.
2.6 “Energy isolating device” is a mechanical device that physically prevents the transmission or release of energy.
2.7 “Energy source” is any electrical, mechanical, hy-draulic, pneumatic, gravitational, chemical, nuclear, thermal, or other energy source that could cause injury.
2.8 “Personal Lock” means a lock for use by an affected worker to ensure personal lockout protection such that each lock when applied is operable only by a key in the worker’s possession.
2.9 “Lockout” means the use of a lock or locks to render the energy isolating device inoperable.
2.10 “Lockbox” is the control point for the key securing system which physically prevents access to keys when locks are applied in a group lockout procedure. 2.11 Identification/Warning Tag” is a tag directing people
not to start or operate locked out equipment and
indicates the name the lock is assigned to, the date of the lockout and reason for the lock out. The identifi-cation/warning tag is attached to each authorized and affected workers’ personal lock.
2.12 Warning Tag” is a numbered tag directing people not to start or operate locked out equipment and references people back to the energy isolation log for date, name and reason for lockout.
2.13 Permanent Lockout Isolations” is equipment, ma-chinery or process that is indefinitely locked out from service.
3.0 Scope of Responsibilities
3.1 Each functional area manager is accountable for ensuring that:
• An energy isolation system is implemented to control the hazards at the worksite
3.2 The functional team lead or designate is responsible for:
• Establishing on site individual training programs for authorized and affected workers that meet the site’s needs for required energy isolation activities • Ensuring the authorized worker(s) are competent
to perform the energy isolation procedures • Determining the requirement for site specific
lockout procedures for equipment being worked on within their area
• There is an adequate inventory of protective equipment and energy isolation devices such as locks, blinds etc. for the job at hand • All workers are trained in STOP-THINK-GO
and Time Out for Safety and feel comfortable in being able to exercise these tools
3.3 The Area Authority in charge or designate is respon-sible for ensuring:
• A proper work permit is issued for the type of work being undertaken and that everyone involved is aware of the hazards, controls and emergency procedures
• The authorized and affected workers are aware of the risks prior to starting work, including the hazards of the energy sources to be controlled, the methods or means to control the energy, and the prohibitions regarding attempts to restart or re-energize locked out and tagged equipment • The equipment to be worked on has been
properly isolated, locked out and tagged and is verified and documented safe to be worked on • Emergency response plans are in place that
addresses unplanned exposure to energy sources from the equipment being worked on • That all required testing, inspection and checking
of the work site is completed prior to the work permit being issued
• That the work area is inspected and checked after the job is completed
3.4 The authorized worker is responsible for ensuring that all equipment and energy sources are properly isolated and locked and tagged with a personal lock prior to starting work.
3.5 The affected workers and authorized workers are responsible for ensuring no work is performed on the equipment until it has come to a complete stop and the affected worker(s) working on the equipment has a personal lock in place at each isolating device or at the group lock box when the group lockout procedure is being used.
4.0 Scope of Expectations
4.1 If the unexpected energization or start-up of equip-ment or the unexpected release of an energy source could cause injury, the energy source must be iso-lated with an energy isolating device and effectively controlled.
4.2 When energy isolating devices must be locked out the devices must be locked and tagged in the position that isolates the affected worker(s) from all hazardous energy when maintenance/servicing work is being performed. Each affected worker must install a personal lock to secure the isolating device in a safe position.
4.3 A work permit is issued by the Area Authority in charge or designate to each trade or group of workers on the job, communicated to all personnel involved in the work, and posted as required.
4.4 A work permit is not issued until a Pre-job Task Hazard Analysis is completed to evaluate risks for all deemed critical and non-routine jobs.
4.5 Workers servicing, maintaining or cleaning cord-con-nected electrical equipment; for example changing grinding wheel or repairing a drill, can lock out the equipment by applying a lock to the electrical plug or render the equipment inoperative. An acceptable approach to rendering the equipment inoperative is for the worker doing the work to:
• Disconnect the plug from its electrical supply • Keep the plug in sight and within reach so that
no else can accidentally plug in the equipment • Keep the plug under his or her exclusive and
immediate control at all times while working on the equipment
4.6 To complete maintenance, troubleshoot problems or perform adjustments, it may be necessary to work on equipment while it is energized. This is allowed only if it is required by the manufacturer or it is not reasonably practicable (in the case where there are no manufacturer specifications) to render the equipment inoperative. For example, adjusting/tuning engines, pigging of pipelines or volt/amp checks on electrical equipment.
4.7 Site specific procedures and controls must be developed and implemented to ensure the work is performed to an equivalent level safely. This approach cannot be used simply because it is more convenient than locking out equipment.
5.0 Scope of Energy Isolation (Lock Out/Tag
Out) General Requirements
5.1 The Area Authority designates an authorized worker to turnoff or shut down machinery using the site specific procedures established for an orderly shut-down in order to avoid any additional or increased hazard(s) to employees. Refer to Isolation Log gHSSEr MF 80001
5.2 A designated authorized worker will physically identify the required isolation points for isolating the equipment or machinery from the energy sources. The authorized worker positions all the energy-isolat-ing devices and applies lock out and tag to isolate the machinery or equipment from the energy source(s). 5.3 Lockout of the equipment will be done with a
lock and tag approved by the Area Authority or designated authorized worker(s). Areas may elect to use a group lockout where a number of workers are working on equipment or a large number of energy isolating devices must be locked out:
• If a group lockout is not used each authorized worker and all affected workers will place their personal lock with an identification/warning tag showing the installer’s printed name, signature, date of installation and reason for installation on each energy isolating device. This is also logged on the Energy Isolation Log sheet. The number of personal locks and tags on each energy isolat-ing device equals the number of authorized and affected workers working on the equipment • For group lockout:
o The authorized worker will lockout and attach a warning tag to each isolation device o
The authorized worker and all affected work-ers place their p The authorized worker and all affected work-ersonal lock on a group lock box with an identification/warning tag with the installer’s printed name, signature, date of installation and reason for installation at-tached to it
o The number of locks on the lock box securing the master key to the lock box equals the number of authorized and affected workers working on the equipment. Each energy isolating device will have the master lock from the lock box secured to it
5.4 Lockout devices must be affixed to each energy or isolating device by the worker authorized by the Area Authority. The devices must be attached in a manner that will hold the energy isolating devices in a “safe” or “off” position.
5.5 Where a tag cannot be affixed directly to the energy isolating device, the tag must be located as closely and safely as possible to the device, in a position that will be immediately obvious to anyone attempting to operate the equipment.
5.6 If more than one group is working on the same item (including different maintenance crafts), each trade or group will verify or test the isolation to confirm a state of zero energy.
5.7 Whenever locks, blinds and tags are installed, details must be recorded in the Energy Isolation Log and be available on site for the duration of the lockout to record and track the status of the isolation. The reference number on the Energy Isolation Log must be recorded on the Permit to Work form completed for any work falling under the isolation.
5.8 All potentially hazardous stored or residual energy must be relieved, disconnected, restrained, or other-wise rendered safe.
5.9 If there is a possibility of re-accumulation of stored energy to a hazardous level, verification of isolation will be continued until the servicing or maintenance is completed, or until the possibility of such accumu-lation no longer exists.
5.10 After ensuring that all personnel are clear, the equipment must be tested to verify that it is properly de-energized, locked out and will not operate. Veri-fication must be documented in the Energy Isolation Log.
5.11 At the beginning of each shift change, the Area Authority, authorized workers or affected workers
will verify that all equipment is safe for work and has not been returned to service during their absence.
6.0 Specific Procedures – Color Identified
Locks
6.1 Each affected worker must install a personal lock color-coded to their respective trade or group of workers prior to commencing work. Such locks will be operated only by the keys of the individual work-ers affected by the isolation. Color-coding applies to BP personnel and FTE. Contractors working on BP sites will apply their own personal locks identifiable with an attached tag.
6.2 Only the affected worker who installed the lock may remove it with exception to emergency or if the worker is not available in which site specific procedures must be followed.
6.3 Each trade will use a different color-coded lock and will use the colors as listed below:
Construction: Yellow Electrical: Blue Instrumentation: Red Mechanics: Orange Operations: Green Permanent Lockout: Black
7.0 Specific Procedures – Group Lockout
(Lockboxes)
7.1 Areas may elect to use a group lockout where a num-ber of workers are working on equipment or a large number of energy isolating devices must be locked out.
7.2 An authorized worker competent in the isolation of equipment is responsible for:
• Locking out the energy isolating devices • Securing the key(s) for the locks used for locking
out energy isolating devices in a lock box by affixing a personal lock on a multiple lock hasp to the lock box
• Completing, signing and posting the Energy Iso-lation Log that identifies the equipment covered by the lock out
7.3 The energy isolation must be verified by two autho-rized workers. Verification must be documented in the Energy Isolation Log.
7.4 The lockbox will contain as many keyed-alike locks as required for the energy isolation. Site specific requirements will determine the size and number of lockboxes required. Each lockbox must contain locks with a key unique only to the locks in the re-spective lockbox. When multiple lockboxes are used on a site each lockbox must have its own identifier corresponding to its respective locks.
7.5 Each affected worker working on the locked out equipment must apply a personal lock to the lockbox referred to in subsection (7.2) before working on the equipment.
7.6 After each affected worker has completed their work they must remove their respective locks. 7.7 When all affected workers’ personal locks are
removed from the lockbox, the authorized worker must ensure that it is safe to end the group lockout. The personal lock of the authorized worker is the last lock to be removed from the lockbox.
8.0 Energy Isolation Process
The following steps identify the process in which the Energy Isolation Practice is to be applied: 8.1 Identify energy source(s) to be isolated – electrical,
pneumatic, mechanical, hydraulic, fluids and gases. 8.2 Identify system and isolation points to be isolated.
Isolate all sources of energy:
• Shut down electrical equipment using the selec-tor switch followed by the master disconnect • Isolate all inlet and outlet piping by closing block
valve(s) upstream and downstream, disconnect-ing, inserting blinds, or use of double block and bleed • Use blocks, pins, or chains to secure potential mechanical energy 8.3 De-energize sources of energy: • Stored electrical, hydraulic, pneumatic and gasses and fluids energy must be bled to obtain zero energy state • In cases where zero energy state cannot be attained control measures must be developed to prevent uncontrolled release of energy. For example, use blocks, pins or chains that are rated to restrain the potential energy when equipment cannot be brought to zero potential energy state • When working on or near exposed de-energized electrical equipment, a qualified person will use testing equipment to ensure that all circuits are dead
8.4 Install/ lockout and tag energy isolation devices: • Lockout energy isolation devices (e.g. block
valves, electrical switches and breakers, mechani-cal devices) • Install blinds or disconnect piping as necessary (lockout required when opening piping) • Affix identifier/ warning tags to each isolation point • Record points in isolation log 8.5 Verify isolation is complete:
• Workers verify zero energy. Ensure that the switch or START button used to test the lockout is returned to its OFF or NEUTRAL position to prevent accidental start-up on re-energization • Isolation points are confirmed to be secure in
safe position
• Personal locks of affected workers control the isolation
8.6 Complete Isolation log:
• All workers applying locks sign off isolation log • Workers verifying isolation sign off isolation log • Confirm all isolation points are recorded • Isolation log remains at site for duration of the
energy isolation procedure
9.0 Blinding/Blanking Guideline
9.1 General:
• All blinding/blanking or disconnecting and plug-ging requires a safe work permit with a master list attached identifying the isolation method and listing the isolation devices and their location. A pre-job meeting (accompanied by a Task Hazard Analysis) needs to be done with all involved
personnel prior to starting work
• Cathodic protection must be shut down and flanges bonded prior to the installation of a blind or disconnecting of piping
• Blinding/blanking or disconnecting and plug-ging is the preferred method of isolation for pipes, pipelines, vessels and equipment • If these cannot be done, the recommended
alternative is double block and bleed. After de-pressuring, the block valves are to be locked and tagged in the closed position and the bleed valve locked and tagged in the open position. The bleed valve venting safely to atmosphere • Single valve isolation is not recommended. If
necessary, then verification must be made that the valve is holding before the work commences. The work must be accompanied by a risk assess-ment and specific site procedure with approval by the Functional Team Leader in charge or des-ignate. Valves (inlet and outlet) must be locked and closed and tagged before work begins 9.2 Blinding and Blanking:
o Every blinding job will have a blind list that was generated by referencing all the available P&ID’s for the system. The system will also be physically inspected to make sure that all the blind locations that were identified on the P&ID’s will completely isolate the system. If extra blinds are required they will be added to the blind list
o All blinding jobs will use a tag system to track blind locations. These tags must be attached to the blind when the blind is installed. A record must be kept of the blinds that have been in-stalled with their respective tag number. Blind boards or multi-part blind tags may be used to
track installed blinds
o After equipment has been made ready to blind (depressured) the operator in charge will use the tag system to track all active blinds. If blind boards are used the tag is moved from the blind board and attached to the blind o Blind equipment as required ensuring the tags
from the board and the blind list correspond with each other
o Each blind location must be recorded in the Energy Isolation Log
9.3 Refer the tables in Appendix A to select proper blind thickness and Appendix B for standard practices for isolation of pipe, pipelines, equipment and vessels.
10.0 Scope of Restoring Service to Equipment
10.1 After each affected worker has completed their work, they will remove their respective locks. Upon remov-ing their locks they must sign off work completed in the Energy Isolation Log.
10.2 In a group lockout once all affected workers’ personal locks are removed from the lockbox, the authorized worker must ensure that it is safe to end the group lockout. The personal lock of the authorized worker is the last lock to be removed from the lockbox. Once all locks have been removed from the lockbox an authorized worker may remove the locks from the energy isolation devices and return them to their respective lockbox. Refer to gHSSEr MF 80001. 10.3 Upon removal of locks and blinds the Energy isolation Log must be updated to record status of isolation. 10.4 A personal lock can only be removed by the autho-Energy Isolation
rized and affected workers who installed the lock. For situations where an authorized or affected worker is unavailable to remove their lock (e.g. off-shift, holidays) or an emergency involving equipment arises, then the Area Authority will complete gHSSEr MF80002 (Removal of Absent Employee Personal Lock Log) to verify that the following steps are completed: • Making every reasonable effort to contact the affected worker who installed the lock • Determining conclusively the job has been com-pleted and no personnel remain in the affected area • Verifying that the machinery can be operated safely before removing the lock
• Contacting the Functional Team for verbal authorization to access spare key stored in desig-nated central location or to cut the lock • Returning the spare key to the designated central
location
• Notifying the worker at the start of his or her next shift that the personal lock was removed since the workers previous shift
• Forwarding completed Form to Functional Team Lead to sign off documentation and verify spare key was returned to designated central location 10.5 Before a machine or equipment is started, affected employees must be notified that all lockout devices(s) have been removed and that all blinds have been accounted for. An authorized worker must verify the de-isolation and complete the Energy Isolation Log. Completed log sheet(s) are filed at a central location for 1 year.
10.6 The individual restoring energy to the equipment must:
• Inspect the work to ensure that non-essential items have been removed
• Ensure that the machine or equipment com-ponents are operationally intact and ready for service
• Check the work area to ensure all employees are safely positioned or removed from the equip-ment
11.0 Permanent Lockout Isolation
11.1 Prior to the installation of a permanent lock, a Management of Change (MOC) will be conducted to determine and verify the correct isolation points. 11.2 The functional team lead will designate an authorized
worker to lock each of the energy isolation devices at the identified isolation points with a permanent lock (black).
11.3 The authorized worker will attach a steel tag to the lock which identifies the date of the lockout, group responsible and a reference number for reference to a log providing details and reference to the MOC. 11.4 The authorized worker will record the lockout on the
energy isolation log and file it at a central location for future reference.
11.5 Keys for the permanent locks must be controlled by the Functional Team Lead.
12.0 Scope of Regulatory References
• Alberta General Safety Regulation (Alberta Regulation 448/83, as amended) • BC Occupational Health and Safety Regulation and Guidelines (BC Regulation 296/97, as amended) Energy Isolation
• Ontario Industrial Establishments Regulation (O.Regulation 851, R.R.O. 1990, as amended)

7. Common tasks carried out using a standard practice certified by Professional Engineer.
8. Unique task carried out using a site specific proce-dure certified by Professional Engineer.
Notes
Note A: All valves must be locked out and tagged when
us-ing double block and bleed, bleed must be vented to atmosphere and consideration must be given to make sure it is vented to a safe place.
Note B: For valves that are holding but the threads/nipple
are unable to accept a bull plug/cap, the bull plug/ cap will not be required until the valve is replaced.
Note C: Double block and bleed cannot be used to isolate
critical hot work in British Columbia. Refer to Provincial regulations outside Alberta.
Note D: This practice needs to be used with other
proce-dures, codes of practice and standards to provide a safe work environment (i.e. Lockout Procedures, H2S Code of Practice).
Blinding/Blanking or Disconnect and plug:
• Blinding/blanking or disconnect and plug is the preferred method for isolating equipment for work purposes
• A blind/blank tag system must be used in all BP Canada facilities. This tag system must also be used for identifying disconnect and plug loca-tions. When a blind/blank is being installed the following are important:
o Site-Specific blinding/blanking procedures or guides must be followed
o Gaskets must be installed on the pressure side and, where possible, on both sides to prevent damage to flange faces
o Proper pressure rated blinds/blanks and gaskets must be used. See specification table at the end of this section
Double Block and Bleed:
If installing blinds/blanks creates a hazard and dis-connect and plug is impractical, the recommended alternative for isolating equipment is closing double (block) valves with a bleed valve in between. The bleed valve size between the block valves must be sufficient to handle potential upstream block valve leakage without applying pressure to the downstream block valve. Block valves must be locked and tagged in a closed position and the bleed valve must be locked and tagged in the open position.
NOTE: Bleed valve outlets must be vented with consideration given to both Safety and Environ-mental impacts
Single Block Valves with Authorization:
Closing of inlet valve and outlet valve and then de-pressuring the equipment. Must verify that the valves hold before work commences. Valves must be locked closed and tagged. Can be used only when approved by a Professional Engineer or Functional Team Lead, based on documented risk assessment complete with site-specific procedure.
Double Block Valves (No Bleed):
Two valves closed on each side of the equipment without de-pressuring between the block valves. The block valve nearest to the inlet and the outlet of the isolated equipment must be locked and tagged closed.
Single Block:
Closing of inlet valve and outlet valve and then de-pressuring the equipment. Must verify that the valves hold before work commences. Valves must be locked closed and tagged.
Unique task:
Task that is unique and requires the expertise of a Professional Engineer to ensure that the equipment isolation meets BP safety requirements and OH&S regulations. Reference Forms: gHSSEr MF 80001 – Energy Isolation Log gHSSEr MF 88001 – Permit to Work gHSSEr MF 34004 – Pre-Job Risk Assessment
GROUND DISTURBANCE PRACTICE
1.0 Scope and Applicability
1.1 This practice applies to all BP Canada Energy BP Canada Gas Performance Unit(CGPU) employees, contracted employees, contractors and other visiting personnel involved in ground disturbance activities on CGPU sites.
1.2 The purpose of this practice is to outline the requirements for ground disturbance necessary to ensure worker safety and to avoid contact with all underground facilities.
2.0 Scope of Definitions
2.1 Ground Disturbance is a man made cut, cavity, trench or depression in the earth’s surface. Examples
include excavating, digging, trenching, plowing, drilling, tunneling, aurgering, back-filling, blasting, hydrovacing, topsoil stripping, land leveling, grading, clearing, fencing, rig anchors and soil sampling.
3.0 Scope of Responsibilty
3.1 Each worker has the responsibility to recognize ground disturbance hazards and take corrective measures by ensuring this practice is followed. 3.2 On-site BP representative in charge or designate
must ensure that:
• Emergency Response Plans are in place to ad-dress Ground Disturbance specific hazards as well as the area Emergency Response Plan • An adequate inventory of Protective Equipment
required for hazards identified for the Ground Disturbance (shoring, cages, gas detection, bar-ricades, harness, lifelines etc.) is available • All protective trench devices temporarily used in
an excavation are to be certified by a Professional Engineer
• A Ground Disturbance permit and, where required, a Confined Space Permit is issued • Ground movement is controlled and collapse
is prevented by systematically shoring, sloping, benching and use of temporary protective devices(see section 5.5)
• A hazard assessment of the worksite is com-pleted prior to work commencing, this includes identification, and where possible, isolation and depressurization of all underground hazards (e.g. pipelines, electric cables) within the area to be disturbed
•
GO and Time Out for Safety and are able to exercise these tools
• All requirements of the Ground Disturbance Code of Practice and Permit have been met
4.0 Scope Of Training And Certification
4.1 All workers involved in the ground disturbance must be trained and competent. This training can be job specific training on site by a person who has received formalized Ground Disturbance Level II training from a recognized institute. The person supervising the job must have formalized Ground Disturbance Level II training.
4.2 Prior to Ground Disturbance activity commenc-ing, a Work Permit and Hazard Assessment Form (gHSSEr MF 88001) and Ground Disturbance permit (gHSSEr MF 84001) shall be completed. Ground Disturbance training is not required for the BP representative completing the Work Permit and Hazard Assessment Form. Any worker who issues a Ground Disturbance permit, supervises or inde-pendently creates a disturbance requires formalized Level II Ground Disturbance training. The Ground Disturbance Permit recipient is not required to have Ground Disturbance training. Permit recipient is not required to have training but person supervising the job must have training and be on-site during the disturbance. Both permits shall be filed at the field office for 13 months.
4.3 Training shall be conducted by a competent trainer. Onsite documentation of training will be entered in the VTA database.
5.0 Scope of Consideration for Ground Disturbance
5.1 A risk assessment is necessary to determine if a ground disturbance permit needs to be completed and all steps followed. This risk assessment needs to be completed by a person trained in ground distur-bance by a recognized institute.
5.2 A Ground Disturbance Permit is required any time powered mechanized equipment is used to disturb the ground. An exemption to this rule would be grading a lease road (see 5.3) as it is considered low risk due to extra ground cover. Certain manual penetrating hand tools can damage underground structures and this should be considered when doing risk analysis.
5.3 Following is a list of jobs that have been identified as low risk jobs and therefore a ground
disturbance permit would not need to be issued: • Using a spade to dig to a depth of less than 30 cm • Pounding in wooden survey peg • Pushing in wire marker flags • Grading a lease road • Using hydro vac at low pressure (< 2200 p.s.i.) to dig 5.4 Hydrovacing or hand exposure is to be used on plant facilities (excluding wellsites) to locate any possible underground facilities. No mechanical excavation. 5.5 A complete hazard assessment for ground
distur-bance needs to address the following areas which are incorporated in the ‘Work Permit and Hazard Assess-ment Form (gHSSEr 88001):
• Consideration must be given to all trenches and excavations being confined spaces.If the atmosphere in an excavation cannot be guaran-teed safe, the excavation would be considered a confined space
• If an excavation is more than 1.5 metres deep and closer to the wall or bank than the depth of the excavation, it must be properly shored or cut back before workers can enter the area. If this is not possible an engineered approved structure for shoring will need to be installed. Proper shoring is as follows:
• If the soil is considered:
o “hard and compact” the walls are sloped to within 1.5 metres of the bottom of the excava-tion at an angle of not less than 30 degrees measured from the vertical
o “likely to crack or crumble” the walls are sloped to within 1.5 metres of the bottom of the excavation at an anlgle of not less than 45 degrees measured from the veritcal o “soft, sandy or loose” the walls are sloped from
the bottom of the excavation at an angle of not less than 45 degrees measured from the vertical
• The employer must ensure the the Spoil Pile is piled so that:
o the leading edge is at least 1 metre away from the edge of the excavation
o the slope of the spoil pile adjacent to the excavation is at an angle of not more than 45 degrees from the horizontal, and
o loose materials are scaled and trimmed from the spoil pile
• The method of identification of underground facilities
• The method of exposure methods and pressures
involved
• Safety and environmental procedures for dealing with encountered or compromised underground facilities
• Specific excavation considerations such as soil type, consistency, natural angle of repose, slurry disposal, contamination, preexcavated, and spoil pile placement
• Size of excavation, proximity to traffic, stability of adjacent improvement, structures, vibration producing equipment, load placement distances and wieght distribution relating to the excavation (vehicles, equipment, piping, lay down areas, etc) •
Engineering certification and design require-ments for excavations > 6 metres (4.6 metres BC) • Methods to stabilize excavation faces, ramping
and proper access & egress points, maintain a safe atmsophere, establish degradation factors (heat, cold, water, soil fluid pressures, environ-mental conditions)
• The work to be carried out, the number of work-ers and tools and equipment in the excavation, PPE requirements and the need for a safety standby
5.6 During the job, in accordance with the permit, ground and atmospheric conditions must be con-tinually monitored for changing conditions. See gHSSEr MS830.
5.7 Heavy equipment (including pickup trucks) must not cross a pipeline unless it is properly ramped or there is a minimum of 1.5 metres of ground cover. The pipeline owner may have more stringent requir-ments therefore this should always be addressed in the pre-project meeting.
