Nexen’s HSE&SR Commitment Statement



This Handbook provides guidelines for establishing and implementing common safe work practices designed to minimize the risks associated with operating, maintenance, and modification activities and the handling of materials and substances that could affect health, safety, or the environment while on a Nexen-operated worksite.

Before work begins, personnel are expected to proactively complete appropriate hazard assessment and documented protective mitigation measures in accordance with Nexen’s Job Safety and Environmental Analysis (JSEA) and Permit to Work programs. Personnel are reminded to reference relevant operating procedures, safe work practices, and emergency response plans in accordance to 30 CFR 250, Subpart S - Safety and Environmental Management System (SEMS) processes.

Nexen, through its Contractor Management Program, will ensure that contractors have their own written safe work practices and, where necessary, contractors may adopt appropriate sections of Nexen's SEMS program.

Despite the urgency or importance of work requirements, Nexen expects tasks to be carried out in a way that protects the health and safety of personnel, the environment, the reputation of the company, and the communities in which we operate.

Do not forget that it is everyone’s responsibility to stop the job if it is not right!

Peter Addy President, Nexen Petroleum USA, Inc.

j) Transfer luggage in the center of the personnel net is not recommended. This practice can cause the debarkation process to be slowed and the rider be delayed in getting to a safe area. There is also the potential for back injury due to the awkwardness of leaning over to get bags. Both risks are increased in rough seas.

k) Do not use personnel carriers in weather, wind, or sea conditions that the qualified crane person considers unsafe.

l) Before any attempt is made to lift personnel with a carrier, give clear instructions to all persons involved.

m) Do not transport personnel suffering from acute seasickness or vertigo by personnel carrier.

n) Any individual has the right to refuse transfer by a personnel basket.

o) Personnel riding on a personnel carrier must wear an approved life vest or life preserver. An approved Type I Personal Flotation Device (PFD) is required for all transfers.

p) Personnel riding on a personnel carrier must stand on the outer rim, evenly spaced, and adjacent to a sidewall opening in the netting, facing inward. Passengers interlock forearms to the inside of the sidewall netting.

q) If crane operator’s view of the primary signalman is obstructed, the personnel carrier should not be moved until alternative communication or signal devices are placed in service.

r) A designated primary landing zone should be marked in a safe area as determined by a JSA.

s) When transferring personnel, lift the personnel carrier only high enough to clear obstructions and gently lower it to the deck.

t) Do not raise or lower a loaded personnel carrier directly over a vessel.

u) The crane operator may refuse to lift any person who does not comply with the operator’s instructions.

v) Provide an experienced escort for persons who are not confident performing a personnel carrier transfer.



w) Injured, ill, or unconfident persons may ride in a sitting position, on the inside of the personnel carrier, with a qualified person as an escort.

4.7.41 Engineering Guidelines

Understanding of some engineering concepts and guidelines will foster a high degree of safety consciousness. An active interest in accident prevention will contribute to improved safety on board the platform. General guidelines to follow at all times while offshore:

a) Load Requirements

i. Never exceed the safe working load or limits of operation of any equipment item/fittings on-board.

ii. Do not load decks to more than the structural capacity limitation.

iii. Do not have the weight of items concentrated over limited sections of the platform’s steel structure. This may promote structural failure, resulting in severe corrosion, or more serious fatigue cracks and brittle fractures.

iv. Try to distribute the loads over the deck area.

b) In steel structures, deterioration mainly originates from corrosion, fatigue, or a combination of both.



c) Never cut any opening on the primary platform structure without approval from the Nexen Engineering Department. Ensure proper material reinforcement when openings are cut in the secondary structures.

d) Never leave tanks with a small quantity of water inside, this will lead to corrosion. The atmosphere in such tanks can become deficient in oxygen due to corrosion resulting from the remains of seawater. If there is reason to suspect a lack of oxygen or the presence of toxic vapors, then start ventilation or gas freeing some time before entry and check the atmosphere before tank entry is allowed.

e) Corrosion on structures and pipes leads to progressive pitting and to safety hazards if left unattended over a period. Ensure corrosion is under control by using various corrosion control methods and proper protective coatings. Consult the PIC when in doubt.

f) Provide adequate maintenance space before putting items near machinery or any mechanical item so that accessibility would not be a problem in times of an emergency.

g) Use certified and rated lifting lugs, shackles, wires, and ropes for lifting jobs.

h) Do not attach any items/equipment to the ‘soft’ points on deck plating or bulkhead plating.

i) Avoid or minimize vibration.

j) If any visible cracks or excessive deformations are found in any part of the platform’s structure, report the matter to the PIC for corrective measures. Timely detection can avoid structural failure. When leaks, ignition sources, and potential hazards are detected, inform the PIC.

4.7.42 Equipment and Piping Isolation

When isolating equipment and piping:

a) Properly isolate, de-pressurize, and/or de-energize equipment and associated piping before any maintenance or repair work is done.

b) Isolation methods can include lockout and tagging of electrical equipment and the use of safety blinds and/or valves to secure piping associated with serviced equipment.

c) When breaking the integrity of piping or equipment, a work permit must be issued before starting the work and necessary safety equipment, such as fire extinguishers and respiratory protection, in place if there is potential to expose the worker to hazardous substances.

d) When breaking the integrity of hazardous or harmful piping under pressure for maintenance, repair, alteration, or replacement, isolate the piping in accordance with current regulations and Nexen practices, which could include the use of blinds or blanks, a double block and bleed method, or another alternate means of isolation that provides adequate protection to workers that



has been approved by Nexen and/or certified as appropriate and safe by a professional engineer.

e) Clearly mark all blinds and blanks. Lock and tag valves used for isolation. Isolation must be in place and proven effective before work begins and remain in place during the work activities.

f) When safety blinds are installed, keep a record of blind number, location, size, and pressure rating and blinds and correctly pressure rate gaskets for their specific service. Refer to Nexen Line and Equipment Breaking Standard for more information.

g) Install gaskets used in conjunction with blinds on the pressure side and where possible, on both sides of the blind.

h) Tag valves used for isolation of equipment ‘Do Not Operate’ and keep a record of the identifying location and position the valve was left in for isolation, for example, open or closed.

i) Before removing locks, blinds or valves, check the isolation log to verify that all blinds have been removed and that all valves have been put back to normal operating position.

j) When isolating equipment for confined space entry, physically disconnect, blind, or isolate all associated piping using the double block and bleed method.

4.7.43 Ergonomics

When allocating jobs to personnel, consider the relationship of the equipment to positioning of personnel.

d) Ring buoys are equipped with water lights and buoyant lines. Buoys are not to be permanently secured, tied, or attached to the platform in any way.

4.7.80 Manual Lifting

Most back injuries are caused by negligence or violation of basic safe lifting rules. Back injuries can be prevented by first assuming a squatting position. Keep the object close to the body and raise the object by straightening the legs. Get help lifting when needed. When lifting, also:

a) Have secure footing.

b) Keep the spine erect, lifting with the legs and not the back.

c) Assess the weight before lifting. If the object is too heavy, get help. To avoid the load on one person, pick up or lay down the object on a given signal.

d) Take advantage of skids, hoist, bars, jacks, blocking, rollers, or hand trucks when moving heavy material.

e) Never pick up or put down an object while in a twisted position.

f) Never be under a heavy object while it is being lifted.

g) Use the same lifting procedures for lightweight objects as you would for heavy weight. Failure to do so may result in needless injury.

h) Limit manual lifting loads to 50 lbs.



4.7.81 Lifting Devices

Refer to Nexen’s Lifting Operations standard for further lifting operations. When using the aid of lifting devices:

a) All lifting devices and material hoists must meet BSEE and Coast Guard requirements and be labeled for maximum lifting capacity.

b) Only competent/qualified, authorized workers shall operate lifting devices.

c) One person is designated as a signalman (flagman) and the lifting device operator takes direction or instruction from the signalman only. However, anyone can give the all-stop signal.

d) Prior to performing a lift, the operator determines the weight of the object to be lifted and ensure that cables, lifting devices, slings, and wire ropes are of sufficient strength, in proper condition, and positioned to support the weight of the load and that the boom angle is appropriate for the load and the expected dynamics of the load.

e) Where critical lifts, such as heavy lifts, lifts over process equipment, or lifts involving two cranes require formal lift plans.

f) For lifts where the operator cannot see the load, at a minimum, a JSA must be completed and a signalman properly positioned to signal the lift.

g) Do not allow any part of the body to extend under any load being lifted by a crane, side boom, or other lifting device.

h) Never attempt to lift unbalanced loads or lift materials directly above workers.

i) Do not use a lifting device to pull loads sideways.

j) Never leave a load suspended while the lifting device is unattended. When shutting down a lifting device leave all the controls in neutral, the brakes locked, and loads lowered to ground level.

k) When hoisting materials, keep loads as close to ground level as possible.

l) Use tag lines to guide the load.

m) Make the inspection and maintenance records for each lifting device available for review by the Nexen Representative.

n) Tag rigging equipment for safe working loads and do not exceed the safe limits established by the manufacturer on loads exerted on rigging. If rigging equipment is not tagged or marked for safe workloads, do not use it until a rating of the equipment can be determined.

o) Verify that running lines of the sling do not contact the shackle bolt.

p) Protect slings from any cutting edges.

q) Do not shorten legs of a sling using knots and/or bolts.

r) Use shackles to pin the eye of the sling or lifting lugs. Do not allow pins to meet the running part of any sling.




s) Hooks on lifting and rigging equipment must have functioning safety latches.

t) When using cranes, pickers or hoisting equipment always consider the following:

i. Proximity to other personnel and equipment ii. Wind velocity iii. Temperatures iv. Reach or extension of lifting equipment v. Weight of the load including the rigging being used

4.7.82 Lightning

Lightning is an electrical discharge caused when static electricity builds up between thunderclouds, or thunderclouds and the ground. Lightning strikes carry up to 100 million volts of electricity and leap from cloud to cloud, or cloud to ground and vice versa. Lightning tends to strike higher ground and prominent objects, especially good conductors of electricity such as metal. Because light travels at a faster speed than sound, you can see a lightning bolt before the sound of thunder reaches you. To judge how close lightning is, count the seconds between the lightning flash and the thunderclap. Each second represents about 1000 feet. For every 5 seconds you count, the lightning flash is approximately one mile away. (e.g., you see lightning and count to 6 before you hear the thunderclap. The lightning would be approximately 1000 feet x 6 seconds = 6000 feet (just over a mile) away.)

a) Follow the 30-30 Rule:

i. If you count less than 30 seconds between lightning flash and thunder bang, stop work and take shelter, preferably in an enclosed building/trailer, an enclosed vehicle, or in a low-lying area avoiding wide open areas or tall isolated objects such as trees or power poles.

ii. Wait for at least 30 minutes after storm has passed or dissipated before resuming work activities.

b) Note that lightning may strike several miles away from the parent cloud. Precautions should be taken even if the thunderstorm is not directly overhead. If you see a flash or lightning but do not hear the thunder, the lightning was probably too far away to hear. Thunder from lightning discharged 15 or more miles away is not usually heard.

c) The Facility PIC is responsible for monitoring the weather and stopping work when required, due to weather.



4.7.83 Lockout/Tagout of Equipment

When using lockout/tagout:

a) When performing maintenance or repair work on air, gas, diesel, electrical, hydraulic, or steam driven equipment, use an approved lockout device in conjunction with other blocking devices, as necessary, to ensure that all equipment is in a zero energy state.

b) No one is to remove another worker’s lock without the approval of a Nexen representative.

c) Use a secure lock and chain on valves if an accidental opening or closing will create a hazard to workers. An alternative would be to use blinding/blanking or double block and bleed systems.

d) Lock, tag, and try off/on switches to verify that the equipment is locked-out before starting work.

e) Neither a ‘Do Not Operate’ tag nor a lock alone constitutes a lockout device; a combination of a lock and tag is required to ensure an effective lockout.

f) Place ’Do Not Operate’ tags on all necessary valves and engagement devices used in the isolating or locking out of equipment.

g) Activate the proper blocking, braking, and securing devices of all equipment when servicing or repairing. Examples may include:

i. Electrical - De-energize all panels relevant to area of maintenance or service and install locks and tags to switches and power disconnects.

ii. Rotating equipment - Lock, secure, and block all movement. Tag the unit. iii. Auxiliary power - Turn off equipment, disconnect battery or starter cables,

shut-off, and tag fuel sources on gas engine drivers. Tag the unit. iv. Remove or control all hazards, pressure conditions, tension, or toxic

substances.

4.7.84 Material Handling

Any item shipped offshore that requires lifting by a crane must be placed in an appropriate container (i.e. basket or cargo container) that has certified rigging pre-installed (pre-slung). Alternatively, if size prohibits the previous requirement and the item has appropriate lifting attachments, installation of certified rigging is required (pre-slung) prior to loading. All rigging utilized on these containers must remain with the container and shall not be removed or replaced unless damaged. Diligence will be required by all to manage the utilization of these containers to assure we have sufficient containers to support our transportation needs. These requirements will assist in loading and offloading our materials creating a safer and less risky environment for our Personnel and Equipment. Refer to Nexen’s Transit Container Code for more information.



4.7.85 Man Overboard

a) On witnessing a person falling overboard or already in the water, give the call "Man Overboard’ by voice or PA system. Try not to lose sight of the person in the water.

b) Directing someone else to make the announcement over the PA system may allow personnel to keep the person in sight. This is important, as it is often very difficult to relocate a person overboard once you have taken your eyes off them.

c) Throw the nearest ring buoy to the individual in the water.

d) Repeat the announcement over the PA system several times. If the location of where the person went overboard is known, include that information in the announcement.

e) The platform personnel will notify the standby boat, where applicable, to commence the rescue operation. Personnel on the facility must be prepared to treat the person, upon retrieval, for hypothermia and any injuries sustained.

f) When appropriate, throwing floatable objects overboard every 5 minutes or so may give rescue boats or aircraft a ‘line of drift’ leading to the person overboard.

g) Assemble the rescue team at the nearest lifeboat, capsule, or rescue craft, if appropriate, to commence the rescue as soon as possible.

h) Maintain communications between the rescue craft and the platform and/or standby vessel at all times. Check communications during each drill.

i) Hold man overboard drills every 3 months as per United States Coast Guard (USCG) requirements weather permitting, to ensure proficiency in retrieving a person overboard is maintained. Log the drills.

j) Get help before trying any rescue attempt.

h) Make MSDS available to ensure that proper PPE is being used.

4.7.113 Rope

When using rope:

a) Do not use rope for lifting or securing purposes. Sisal rope exposed to the sun will deteriorate, become brittle, and could break at limits below those expected for the size of rope.

b) Rope can be used for tag lines and for securing small lightweight items during platform moves.



4.7.114 S.A.F.E chart

API RP 14C requires the development of SAFE charts (cause-and-effect charts) and safety flow diagrams (P&ID diagrams showing equipment and safety devices). The BSEE requires them to be submitted during the design phase of any project production.

In the SAFE chart for each piece of process equipment, all the required safety devices are listed, and those that have been excluded have the reference to the safety analysis checklist, which lists all the reasons for excluding a device. The SAFE chart becomes an easy tool to check that all requirements have been met and what actions the safety devices take.

4.7.115 Safety Body Harness

When using a safety body harness:

a) A full body harness must be worn for:

i. Fall protection from height above 6 feet vertical from a temporary work site, and/or above 4 feet vertical from a permanent work site.

ii. When completing hazardous confined space work.

iii. When using a man basket as part of the work.

b) Contractors must be fully aware of and following the Regulations regarding the use of full body harnesses. When the use of one of these devices is required, the contractor must ensure that they are properly maintained and used.

c) Ensure the proper fall protection is worn for the task being conducted (i.e., chest d-ring for ascending and descending ladder safe systems and to aid in rescue).

4.7.116 Scaffolding or Temporary Work Platforms

When working on scaffolding or platforms:

a) Provide toe boards and guardrails on any work platforms above 6 feet in case of a temporary installation or 4 feet in case of a permanent installation.

b) Construct, maintain, and use scaffolds or platforms used for installation, maintenance, or removal of equipment according to specific regulations and industry standards.

c) Scaffolding must be:

i. Erected by a competent person. ii. Anchored to prevent accidental movement. iii. Equipped with guardrails and toe boards if the working height

exceeds 10 feet or if the scaffold is erected over an area, where others will be working or passing by.



d) Before using scaffolding, it must be inspected and tagged by a competent person. Scaffold identification tags are color coded for each reference and should be located at point of access. These colored tags are:

i. Green tag - No restrictions: Safe for use. ii. Yellow tag – Caution: Scaffold has special requirements for safe

use. iii. Red tag – Danger: Do not use as it has been deemed unsafe.

4.7.117 Searches

All personnel on Nexen facilities must consent to and cooperate with searches of areas and items on the Company Premises including (1) their person; (2) their personal belongings, including but not limited to toolboxes, luggage, and similar items; (3) their work areas and sleeping quarters; and (4) all vehicles and equipment. Any individual who refuses to consent to or cooperate with a search may be removed from the Premises and denied future entry.

4.7.118 Sheen on Water

Nexen reports all spills and loss of containment of hydrocarbon based fluids including Glycol and hydraulic fluid. In GoM, any sheen visible on the water surface from these products is reported. Refer to Section 4.10.1 Spills for more details.

4.7.119 Slings

Refer to Nexen’s Lifting Operations standard for further information. When using slings:

a) Inspect wire rope, cable clamps, shackles, sheaves, and thimbles prior to each use. Use the correct number of cable clamps.

b) Replace wire rope when broken strands or wire, crushed wire, bird caging, kinking, weather or chemical corrosion, damage to eyes or damage to other fittings, is observed.

c) Slings must have a permanent inspection tag affixed and certifications available at the facility.

d) Discard defective wire rope.

e) Check slings prior to each job.

f) When not in use, properly store slings and wire rope in a protected area.

g) Issue and Use of Fiber/Soft Slings

i. Slings commonly made from canvas or manufactured fiber, such as nylon or polypropylenes, are referred to as ‘fiber’ or ‘soft’ slings. These slings have an advantage over traditional wire rope slings




when grip is required on small diameter machined surfaces or where minimal damage to machined or soft surfaces is required.

ii. Treat fiber or soft slings as tools with specific purposes and not general lifting devices for all occasions.

h) Personnel on each Nexen platform will strictly adhere to the following:

i. Carefully consider the load to be lifted, the weight of the load, and an alternate means of lifting to determine the use of each sling.

ii. When sling type is determined, conduct a JSEA to review the step-by-step lifting procedure to identify hazards and determine risks.

iii. Specify the precautions to minimize risk on a JSEA form, authorized by the PIC.

i) A register will be maintained on the platform that will provide the following details for each fiber or soft sling:

i. Swing Weight Limit (SWL) ii. Date the sling entered service iii. Identification mark/serial number

4.7.120 Slips, Trips and Falls

Slips

Whenever any substance has been spilled or is standing, clean it up immediately before pursuing any other job. Report sources of spills/wet spots to ensure repairs are made. If the identity of the spilled substance is unknown, identify it and use proper cleanup and disposal techniques. If you must walk on wet surfaces, take short steps to lessen the chance of slipping and keep your hands free and out of your pockets to ensure better balance. Wear slip-resistant shoes and keep them clean. Never run.

Trips

Use designated walkways or access routes whenever possible. Be aware however, that in spite of best efforts to eliminate tripping hazards, some tripping hazards will still exist. Stay focused and concentrate on the path ahead of you.

Falls

Climbing up and down ladders requires the use of both hands. To avoid slips and falls, walking up and down stairs requires the use of at least 1 handrail.

There are instances when making two trips or calling for help to carry a load may seem too time consuming. To avoid injury, slow down. Use both hands on ladders and go up and down stairs with at least 1 hand on the handrail.



4.7.121 Smoking

When smoking offshore:

a) Only smoke in designated smoking areas on the platform.

b) Clearly identify designated smoking areas identified by posted signs.

c) Do not smoke in the living quarters.

d) Do not take smoking materials, including matches, out of the accommodation.

4.7.122 Station Bill (Manned Platforms)

The Station Bill provides specific instructions on where each person is to go and what to do in the event of a fire, man overboard, or abandonment. It is the responsibility of personnel to read, understand, and comply with the Station Bill. Personnel must know the alarm signals, their emergency stations, and their duties at the station. Should the general alarm sound, personnel are to report to their designated stations with proper clothing and/or equipment, as required by the Station Bill.

The Station Bill shall be posted and made available to all personnel on the facility.

4.7.123 Spills

Refer to Section 4.10.1 Spills.

4.7.124 Swing Rope transfers

A swing rope is commonly used to transfer personnel from boats to the landing area of the platform. Using a swing rope can be demanding, especially in moderate to heavy sea conditions. Follow all severe weather restriction guidelines.

Note Transfers should occur only during daylight unless approved by person in charge.

Transfer by the swing rope:

a) Deck hand should always be available for swing transfers.

b) Personnel shall face where the boat is bumping against the offshore structure, if seas allow boat to bump the structure, or where boat is at a safe position as determined by the Boat Captain.

c) Use correct rope for outboard or inboard swing.

d) Have both hands and arms free, catch the knotted rope when the boat is at top of a swell, and swing to the structure by pushing off from the boat with your feet.



e) Do not let the swing rope get between your legs. Always keep feet and legs clear of the structure's landing.

f) Ensure there is proper lighting of the boat or platform landing area.

g) Wear a Type I PFD while transferring.

Note Do not carry luggage, tools, or any other items while transferring by swing rope.

4.7.125 Tag Lines

Tag lines play an important part in helping to maneuver, control, and position loads being moved by cranes. When using tag lines:

a) Do not tie or wrap tag lines around the hands or bodies of people using them.

b) Do not make knots at the end of the tag lines.

c) Use the length that is appropriate for the lift.

4.7.126 Tie-Ins to Nexen Equipment

Contractors must not tie into existing Nexen facilities, including pipelines, electrical power circuits, and all other equipment without specific written approval from the Nexen Representative.

4.7.127 Tool Usage

When using tools:

a) Use tools only for their proper function and keep them in good condition. Do not use defective or altered tools.

b) Operators visually inspect equipment and verify it is in safe operating condition before starting work.

c) Disconnect the power source from a tool and/or depressurize before adjusting the tool.

d) Properly fit guards and verify good condition at all times.

e) Label grinders and grinding discs to indicate maximum RPM and check for correct size and speed prior to fitting.

f) Wear appropriate personal protective equipment at all times when using any tools.

g) Only competent and properly trained workers operate power tools. Use only ANSI approved properly grounded electrical tools with 3-pronged plugs or double insulation or ground fault insulation. Do not use switch lock-on devices with any electrical or air-powered tool.

h) Explosive-actuated fastening tools must meet all requirements of the current NFPA 70 and be used only by trained, competent workers.



i) Before using electric tools in potentially flammable atmospheres, issue a Hot Work Permit and conduct suitable testing. Complete documentation that:

i. Indicates whether the atmosphere contains a flammable substance in a quantity sufficient to create an explosive atmosphere.

ii. Confirms work may be safely performed.

4.7.128 Trailing Hand Technique

The “Trailing Hand Technique” is used to reduce the chance of injury if a slip and fall occurs while descending a stairway. To practice this technique:

a) Grasp the handrail behind in a trailing motion while descending stairs. This will give more control in case of a slip. If a person does slip and fall, there will be enough control to be able to go into a sitting position instead of falling forward.

b) The use of the trailing hand technique also has the effect of twisting the body when descending stairs, causing more of the foot to be placed on the stair tread, giving a better grip for the feet and hands.

c) Personnel working on platforms or any shore base facility must use the trailing hand technique when descending stairs.

4.7.129 Using Nexen Equipment

When using Nexen equipment:

a) Contract personnel must not operate any switches, valves, or controls on Nexen equipment unless specifically authorized to do so by the Nexen Representative.

b) Contractors shall not tie in to existing Nexen facilities including pipelines, sewer system, electrical power circuits, or any other equipment, without specific approval from Nexen Representative. Install blinds, locks and other safeguards to the satisfaction of Nexen and all other affected personnel. Once approved tie-ins have been made to existing Nexen equipment, the entire system is considered as Nexen property for the purpose of control.

4.7.130 Waste Management

Nexen’s Waste Management Plan is a guidance document identifying the appropriate management practices for each type of waste generated by exploration and production operations. The plan gives guidance for field and staff personnel and contractors on handling, characterizing and disposing of wastes generated by oil and gas operations.




4.7.131 Weather Restrictions for Crane Operations

The decision to make a lift is left up to the crane operator and the boat captain. When incidents occur during adverse weather conditions, it is easy to question why the decision was made to make the lift. Even a routine lift can cause property damage or personal injury when weather conditions exceed certain conditions. The intent of these recommendations is to ensure that all of the appropriate personnel are involved in the decision to proceed or to shut down crane operations. It also documents that the decision was based on the information gathered and discussed at the work site and that the best decision was made based on the information available.

Note Nexen’s Crane Operations and Maintenance Program currently does not address any restrictions due to weather conditions.

Crane JSA Requirements

Dynamic load charts are designed using 6-8 foot seas and 24 mph wind speeds. Therefore, when actual conditions meet or exceed these limits, a Crane JSA should be completed to reflect that the factors listed below have been considered and documented. The Crane JSA discussion should include the following personnel:

a) Crane Operator.

b) Boat Captain.

c) Third-party Crane Operator’s supervisor.

d) Facility Supervisor.

e) Construction Foreman or Contract Inspector where applicable.

All factors below should be considered and discussed and a mutual decision should be made. All personnel involved in the discussion shall sign the JSA.

Factors to Consider

There are many factors that go into the final decision and the following factors should be considered when decisions are made to operate the crane. These factors include:

a) Crane to be used.

b) Skill and experience of crane operator and riggers.

c) Skill and experience of the boat captain.

d) Weight of the load.

e) Size and configuration of the cargo to be lifted.



f) Dynamic lifting capacity and lift angle.

g) Current speed and direction.

h) Position of cargo to be lifted.

i) How much other cargo is on boat?

j) Is sufficient lighting available during operations before daylight hours or after dark?

When weather conditions deteriorate beyond a certain point, crane operations should not proceed. Refer to Table 2 – Weather Stops for Crane Operations as a general guideline.

Weather Stops for Crane Operations

When stopping crane operations, even if all parties agree to proceed with a lifting operation, a ‘Stop Work Authority’ can and should still be used if the situation is deemed unsafe to proceed.

Crane Operations must be stopped under the conditions shown in the following table:

Weather and Sea Conditions that Stop Crane Operations

Operations Stopped

Seas meet or exceed 12 feet All Dynamic Crane Operations

Winds meet or exceed 35 mph All Crane Operations, Static and Dynamic

Lightning in the vicinity All Crane Operations, Static and Dynamic

Table 2 – Weather Stops for Crane Operations

4.7.132 Water Transportation

There may be times when crew changes are done by boat. Should this happen, personnel must follow instructions given by the boat crew.

4.7.133 Welding/Welders

When welding, follow regulations, hot work authorization permits, and:

a) Only competent/qualified and authorized workers shall use welding, cutting, and grinding equipment.

b) Do welding and hot work with the permission of the Nexen PIC, Construction Inspector, or person with delegated authority, under a Hot Work Permit.

c) The supervisor responsible for the job ensures that safe welding procedures are followed, including proper welding grounding procedure, the use of welding flash shields, and eye protection for aides.



d) All welders entering a Nexen work site must wear flame resistant clothing fully covering the arms, legs, and torso, meeting standards for NFPA 2112. If the welder’s outerwear is non-fire resistant, the welder must wear FRC under their non-fire resistant rated welding garments as needed to ensure that body parts not covered by these welding garments are adequately protected.

e) Take suitable precautions to prevent exposure to personnel from excessive ultraviolet radiation, fire, explosion, asphyxiation, toxic gases, fumes, or dust when welding or cutting equipment is being used.

f) Equip gas-welding hoses with appropriate flame arresters or check valves.

4.7.134 Working over Water

When working over water:

a) Consider environmental and rescue arrangements before authorizing personnel to work over water.

b) At a minimum, wear a full body harness with properly secured lanyards and/or retractable lifelines and a life preserver. Keep persons working over water under surveillance by either a fellow worker or a person specifically designated.

c) Any work over the water, or any other position where a fall to the water is possible, shall be a Work Authorization Permitted activity.

d) Advise the standby boat, where applicable, of the operation and the expected time involved so as to allow the standby boat to remain at an appropriate state of readiness to assist if the need should arise.

4.8 Work Authorization Permits

Note

This handbook cannot state all situations that require a work permit, therefore, the Nexen Representative and/or the contractor, must work in a responsible manner to identify and control the hazards found at the work location when known, regardless of whether a work permit is issued or not.

Work Authorization Permits are intended to ensure potentially hazardous work is carried out under safe working conditions. The permit system is a 2-way arrangement and the responsibility for taking special precautions rests on both the issuer and the receiver of the permit. Prior to starting work contractors are expected to discuss work permit requirements with the Nexen representative.

When a work permit is issued from an area other than at the immediate work site, an agreement will be made between the two parties regarding who will be



responsible to perform the site hazard assessment prior to work starting and which hazard assessment form will be used to document the assessment.

If working under a Term Work Authorization (greater than 1 day), the contractor carries a copy of the agreement and those working under the agreement must be familiar with it, working in compliance with the expectations outlined. Refer to the Work Authorization Permit (Hot and Cold) standard for more information.

Note Nexen DSM will also sign off on hot work, working over water, transfer of base oil, and confined space entry permits when working with MODU Contractors or as part of a SIMOPS program.

APPENDIX D – UV INDEX

UV Index: How to use it

As described in other sections of the UV information, the UV Index is a forecast of the probable intensity of skin damaging ultraviolet radiation reaching the surface during the solar noon hour (11:30-12:30 local standard time or 12:30-13:30 local daylight time). The greater the UV Index is the greater the amount of skin damaging UV radiation. How much UV radiation is needed to actually damage one's skin is dependant on several factors. But in general the darker one's skin is, (that is the more melanin one has in his/her skin) the longer (or the more UV radiation) it takes to cause erythema (skin reddening). Figure 1 shows a look up chart where by one can cross check his/her propensity to burn versus the UV Index. For those who always burn and never tan the times to burn are relatively short compared to those who almost always tan.

The EPA has devised general guidelines as far as what to do to protect oneself from overexposure to UV radiation. These are shown in the table below.

Exposure Category UV Index Protective Actions

Minimal 0, 1, 2 Apply skin protection factor (SPF) 15 sun screen.

Low 3, 4 SPF 15 & protective clothing (hat)

Moderate 5, 6 SPF 15, protective clothing, and UV-A&B sun glasses.

High 7, 8, 9 SPF 15, protective clothing, sun glasses and make attempts to avoid the sun between 10am to 4pm.

Very High 10+ SPF 15, protective clothing, sun glasses and avoid being in the sun between 10am to 4pm.

APPENDIX G – HEALTH EFFECTS OF HEAT STRESS

Health Effect Symptoms Treatment

Heat Rash Red bumpy rash with severe itching

Change into dry clothes and avoid hot environments. Rinse skin with cool water. Wash regularly to keep skin clean and dry.

Fainting Sudden fainting after at least two hours of work; cool, moist skin; weak pulse.

GET MEDICAL ATTENTION: Assess the need for CPR. Move to a cool area, loosen clothing, make person lie down, and if the person is conscious, offer sips of cool water. NOTE: Fainting may also be due to other illnesses.

Heat Cramps

Painful, involuntary muscle spasms that usually occur during heavy exercise in hot environments. Inadequate fluid intake often contributes to this problem. The spasms may be more intense and more prolonged than typical nocturnal leg cramps.

Muscles most often affected include the calves, arms, and abdomen and back, although the cramps may involve any muscle group involved in the exercise.

Rest briefly and cool down. Drink water or an electrolyte-containing sports drink. Practice gentle, range-of-motion stretching and gently massage the affected muscle group.

Heat Exhaustion

Signs and symptoms of heat exhaustion often begin suddenly, sometimes after excessive exercise, perspiration, and inadequate fluid intake. Features resemble shock and include: feeling faint, nausea, ashen appearance, rapid heartbeat, low blood pressure, hot, red, dry or sweaty skin, low-grade fever, generally less than 104°F.

Get out of the sun and into a shady or air-conditioned location. Lay the person down and elevate the feet slightly. Loosen or remove the individual’s clothing. Have the person drink cold water, not iced, or a sports drink containing electrolytes. Cool the person by spraying them with cool water and fanning. Monitor the person carefully. Heat exhaustion can quickly become heatstroke. If fever - especially greater than 104°F -fainting, confusion, or seizures occur, CALL FOR EMERGENCY MEDICAL ASSISTANCE.



Health Effect Symptoms Treatment

Heat Stroke

The main sign of heatstroke is a markedly elevated temperature - generally greater than 104°F - with hot, dry skin and changes in mental status ranging from personality changes to confusion and coma. Other signs may include rapid heartbeat, rapid and shallow breathing, elevated or lowered blood pressure, cessation of sweating, irritability, confusion or unconsciousness, fainting, which can be the first sign in older adults.

Move out of the sun and into a shady or air-conditioned space. Dial CALL FOR EMERGENCY MEDICAL ASSISTANCE. Cool the person by covering them with damp sheets or by spraying with cool water. Direct air onto the person with a fan or newspaper.

How Forecasters Decide Whether to Issue Excessive Heat Products

NOAA's heat alert procedures are based mainly on Heat Index Values. The "Heat Index", sometimes referred to as the "apparent temperature" and given in degrees Fahrenheit, is a measure of how hot it really feels when relative humidity is added to the actual air temperature.

To find the heat index, look at the Heat Index Chart. As an example, if the air temperature is 96°F (found on the top of the table) and the relative humidity is 65% (found on the left of the table), the heat index-or how hot it really feels-is 121°F. This is at the intersection of the 96° column and the 65% row. The National Weather Service will initiate alert procedures when the Heat Index is expected to exceed 105°- 110°F (depending on local climate) for at least two consecutive days.

IMPORTANT: Since heat index values were devised for shady, light wind conditions, EXPOSURE TO FULL SUNSHINE CAN INCREASE HEAT INDEX VALUES BY UP TO 15°F. Also, STRONG WINDS, PARTICULARLY WITH VERY HOT, DRY AIR, CAN BE EXTREMELY HAZARDOUS.

Note on the Heat Index Chart shaded zone above 105°F. This corresponds to a level that may cause increasingly severe heat disorders with continued exposure and/or physical activity.

Vulnerability to Heat Stress: Many permanent or temporary conditions (e.g. age, heart or lung conditions, dehydration, fatigue, some medications) can make a person more vulnerable to heat strain. Despite these conditions, workers may be able to cope given adequate knowledge of the signs and symptoms of heat stress and the latitude to make the appropriate adjustments to their pace of work. More often, the young, fit workers may think they are invincible who succumb to heat strain. Some workers may need medical advice about what accommodations would be right for them.

HEAT SAFETY:

a) Slow down. Strenuous activities should be reduced, eliminated, or rescheduled to the coolest time of the day. Individuals at risk should stay in the coolest available place, not necessarily indoors.

b) Dress for summer. Lightweight light-colored clothing reflects heat and sunlight, and helps your body maintain normal temperatures.

c) Put less fuel on your inner fires. Foods (like proteins) that increase metabolic heat production also increase water loss.

d) Drink plenty of water or other non-alcohol fluids. Your body needs water to keep cool. Drink plenty of fluids even if you don't feel thirsty. Persons who (1) have epilepsy or heart, kidney, or liver disease, (2) are on fluid restrictive diets or (3) have a problem with fluid retention should consult a physician before increasing their consumption of fluids. Do not drink alcoholic beverages.

e) Spend more time in air-conditioned places. Air conditioning in homes and other buildings markedly reduces danger from the heat. If you cannot afford an air conditioner, spending some time each day (during hot weather) in an air conditioned environment affords some protection.

f) Don't get too much sun. Sunburn makes the job of heat dissipation that much more difficult

g) Do not take salt tablets unless specified by a physician.



APPENDIX H – RISK MATRIX (Risk = Consequences x Likelihood)

Consequence

Describe below what is the most likely, worst-case scenario that might have occurred under slightly different circumstances. For example, A 20 lb. dropped object that narrowly missed a worker on the drill floor could have resulted in a fatality and be rated as Critical (4). Similarly, a head-on vehicle collision

with minor injuries that could have resulted in multiple fatalities shall be rated as Catastrophic (5).

After a Risk Assessment has been conducted, look to implement all possible risk reduction measures when initial assessments indicate low, medium, or high-risk levels. Refer to HSE&SR manuals, handbooks, procedures, standards, code of practices, and so on to help determine most practicable risk reduction measures. Taking into account the applicable risk reduction measures identified, redo risk assessment to determine level of residual risk still associated with conducting the specific work activities. Use the Approval Guide to help determine the level of approvals needed depending on the outcome of the residual risk assessment.

RISK CONTROL GUIDE (Refer to HSE&SR manuals, handbooks, work procedures, and/or codes of practice for possible risk reduction measures) Insignificant Risk/Low Risk: Manage risk through controls identified in Work Permit and Pre-Work Hazard Assessment. Medium Risk: Alert: Involve Lead Operator/Supervisor or HSE&SR staff to determine risk control plan. High Risk: Stop Work! Work should not proceed until Senior Lead/Supervisor and HSE&SR are involved in risk control plan, the risk is lowered and/or the task is redefined.
