 The height of the scaffold in relation to the minimum base width

Note: Freestanding Scaffolds with a height in excess of 4 times internally or 3.5

times externally, the minimum base width dimension must always be

secured to a rigid structure or seek alternative means of support.

Internally = no wind loading

Externally = relatively sheltered locations / minor wind loading

 Wind loads

 The use of brackets or cantilevered platforms

 Imposed scaffold loads.

Ties:

 The bottom tie must be placed no higher than four (4) times the minimum base width

and every four (4) meters vertically thereafter. Ties should be placed as close to the

top of the scaffold as possible and, in no case, more than three (3) times the

minimum base width of the scaffold from the top.

 Vertical ties should be placed at the ends of scaffold runs and at no more than 4

meters horizontal intervals in between.

 Ties should be installed as the erection progresses and not removed until the scaffold

is dismantled to that height.

 Ties should be constructed to 6.25kn (slipload), unsheeted & 12.5kn sheeted

Guys:

 Each leg of a freestanding tower must be guyed at the intervals outlined above or

otherwise restrained to prevent tipping or overturning.

Note: Circular scaffolds erected completely around or within a structure may

be restrained from tipping by the use of "stand off" bracing members.

5.1.2.5 Planks change to boards

 Work platforms must be fully boarded either with scaffold graded solid sawn or

laminated boards, in good sound condition, or with fabricated platforms in good

condition.

 Each board must overlap the support by a minimum of 1.5 x thickness or be cleated /

securely tied for example,

3 metre board on

2.8 meter spans must be

cleated/securely tied.

 Boards must not extend beyond the support by more than 4.5 x thickness. Such

overhangs should be separated from the work platform by guard-railing so that they

cannot be walked on.

 Spans of full thickness, 50mm by 250mm scaffold grade boards, should never exceed

2.6m. Loads on boards should be evenly distributed and not exceed the allowable

loads for the type of board being used.

 Spans of normal thickness (38mm) boards should never exceed 1.5m.

 Boards and/or platforms should always be secured to scaffolding to prevent uplift or

displacement due to high winds or other job conditions.

5.1.2.6 Guardrails and Toe Boards

 The height of the top guardrails shall be between 910mm & 1150mm and distance

between the posts of guardrails should not exceed 2.7 metres.

 Guardrails must be used on all open sides and ends of scaffold platforms. Both top

and mid-rails are required.

5.1.2.7 Transoms

A transom is a length of scaffold tubular used as a cross-member to support boards on

working lifts & provide lateral structural support on non-working lifts. Particular care and

attention shall be paid to the use of transoms. In particular:

 Transoms should overhang the support points by at least 150mm

 Transoms hangers shall be used with bolts fastened to support transoms on frames

 Transom spans greater than 2.7m (very light duty), 2.4m (light duty) or 2.1m (general

purpose) require knee bracing and lateral support

 Transoms used as side or end brackets need special bracing.

Note: Transoms must not be used for the storage of materials.

5.1.2.8 Scaffold Access

Access must be provided to all work platforms. If it is not available from the structure, access

ladders, frames with built-in ladders, or stairways must be provided. When frames with built-

in ladders are used, cleated boards or fabricated boards must be used at platform levels to

minimize or eliminate platform overhang. Access ladders must extend at least 1 metre above

platforms.

5.1.2.9 Bridging Scaffold

Bridging between towers should not be done with boards or stages unless the overturning

moments have been compensated for & suitable guardrails, ties etc are fitted.

5.1.2.10 Mud Sills and Screw Jacks

Mud sills must be of adequate size to distribute the loads on the scaffolding to the soil or

supporting structure. Sills should be level and in full contact with the supporting surface.

Base plates or screw jacks with base plates must be in firm contact with both the sills and the

legs of the scaffolding. Compensate for uneven ground with screw jacks with base plates.

DO NOT USE unstable objects such as blocks, loose bricks, etc.

5.1.2.11 Dismantling Scaffold

Dismantling system scaffolding is more or less just the reverse of erection. Dismantling

guardrails is to be started at the top. Each piece shall be removed and lowered as one

unsecures it. Unsecured pieces must not be left in place, even for a moment.

5.1.3 Rolling Scaffolds

The tower height must not exceed 3.5 times internally or 3 times externally the minimum

base dimension. Outrigger frames or outrigger units on both sides of the tower may be used

to increase base width dimension when necessary.

All casters must be secured to frame legs or screw jacks with a nut and bolt or other secure

means. Total weight of tower + men, materials & tools etc should not exceed the capacity of

the casters.

Screw jacks must not be extended more than 300mm above caster base. Tower must be

kept level and plumb at all times.

Horizontal/diagonal (plan) bracing must be used at the bottom and top of tower and at least

every alternate lift. Fabricated boards with hooks may replace the top diagonal brace.

 All frames must be fully cross-braced

 Only prefabricated boards or cleated / tied boards should be used

 Casters must be locked at all times the scaffold is not being moved

5.2 INSPECTIONS AND SCAFFTAGS

5.2.1 Inspection

Inspection of the scaffolding is to be done before each use. In particular, check:

 The Scafftag - Pay particular attention to the load rating

 That the scaffold is assembled correctly:

o that it is level and plumb

o base plates are in firm contact with sills

o bracing is in place and connected

o platforms are fully boarded with guardrails in place

o safe access is provided

o that the scaffold is properly tied and/or guyed

5.2.2 Site Inspection (Pre-Construction)

The job site should be inspected to determine ground conditions or strength of supporting

structure, and for proximity of electric power lines, overhead obstructions, wind conditions,

the need for overhead protection or weather protection coverings. Special care is needed

when scaffolding is to be erected on fill or other soft ground or on frozen ground. These

conditions must be evaluated and suitably provided for. Any underground services and

recorded subsidence are to be identified.

A competent person shall inspect scaffolding:

 Before it is first used and then at least once every week

 Following any alteration

 Re-inspect scaffolding where applicable each time before (using relevant

onshore/offshore sites Adverse Weather Guidance) and straight after it has been

exposed to adverse weather conditions likely to affect its strength or stability.

Details of inspections must be recorded & must be auditable.

5.2.4 Scafftags

“Scafftags” shall be used on all scaffold structures, if complete or partially

complete/dismantled to indicate whether or not the scaffolding is safe to use.

Scafftags must be positioned prominently at access points to scaffold structures.

When scaffolding is incomplete (whether partly erected or dismantled) or considered to be

unsafe for any reason, the green scafftag must be pulled to display the red (Do Not Use) tag.

In addition, access to the scaffold shall be barriered off as soon as practicable.

5.3 SCAFFOLDING USE

5.3.1 Access

Use only the safe means of access provided. Do not climb bracing or frames not specifically

designed for climbing. If access is not provided, insist that it be provided.

5.3.2 Working Safely

5.3.2.1 Personnel Movement on Scaffold

While working on scaffold, personnel shall take care to climb safely. The following work

practices shall apply:

 When on ladders:

o face the rungs as you climb up or down.

o use both hands on the ladder and maintain „three point‟ contact (keep one hand

firmly on frame or ladder at all times)

o do not try to carry materials while you climb

o ensure footing and balance before releasing hand grips

o do not work on / from the access ladder

 Do not overload platforms with materials

 Never add sheeting to a scaffold structure without consulting a qualified person.

 Do not extend working heights by using boards guardrails or by use of boxes or

ladders on scaffold platforms

 Do not remove any component of a completed scaffold assembly. Alterations shall

only be carried out by suitably qualified / authorised personnel under the supervision of

a qualified person.

Note: Any removed or damaged component should be immediately replaced.

5.3.2.2 Dropped Objects

Only the required tools and materials for the job should be on scaffolding, any loose cuttings

or materials generated by the work should be removed immediately to prevent any trips or

slips. When the work scope is completed, the scaffold area should be cleared of all tools and

debris created from the work as the normal housekeeping exercise at job completion.

Loose articles and materials must be kept to an absolute minimum on scaffolding platforms.

All necessary precautions must be taken to prevent objects from falling from scaffolds, e.g.

by use of toe boards, barriers, etc.

5.3.2.3 Cantilevered Platforms

Materials should never be placed on cantilevered platforms unless the assembly has been

designed to support material loads. (These types of platforms cause overturning and uplift

forces, which must be compensated for. All frames should be fastened together to prevent

uplift an overturning moment compensated for with counterweights or adequate ties).

5.3.2.4 Hoisting and Lifting

Scaffolds should not be used as material hoist towers or for mounting derricks unless the

assembly is designed for that purpose.

5.3.3 Rolling Scaffolding

 Do not ride manually propelled rolling scaffold. No personnel should be on the tower

while it is being moved.

 Lock all casters before getting on the tower.

 Work only within the platform area: do not try to extend overhead work area by

reaching out over guard railing.

 Do not bridge between two rolling towers with boards or stages.

 Secure all materials before moving scaffolds.

 Be sure floor surface is clear of obstructions or holes before moving scaffold.

 Be sure there are no overhead obstructions or electric power lines in the path of

rolling scaffold.

 Rolling towers must only be used on level surfaces.

 Move rolling towers by pushing at the base level only. Do not pull from the top.

such as restricting use to non-hazardous areas and appropriate storage.

Site specific procedure needs to be in place approved by Site Manager.

Due to a risk of an incentive spark should there be the presence of residual aluminium on

oxidised steel surface the use of equipment constructed using aluminium alloys should be

minimised and the limited use of such equipment is to be permitted providing the following

conditions:

 The use of aluminium based access systems should be subject to a specific risk

assessment

 Personnel using aluminium equipment should be aware of the hazards associated

with aluminium equipment and should also:

Avoid any unnecessary contact between aluminium alloys and rusty steel

(rubbing, dragging, hammering, bumping, dropping)

Portable equipment represents the higher risk, because of the increased risk

of dropping or banging such objects. The hazard of aluminium on rusty steel is

far higher than the hazard of rusty steel on aluminium

Consider the movement of any portable equipment constructed with light

alloys to be a risk

Where possible and practicable, protect exposed areas of aluminium on

portable equipment (edges or corners) in some appropriate manner

 In non-hazardous zones where the chance of flammable atmosphere is small, the

introduction of light alloys could be called a negligible risk, except in situations where

heavy impact could be likely, or release of flammable material is more likely.

5.4 LADDERS

Ladders may be used as a short-term alternative to scaffolding or as means of access to

scaffolding, providing the points listed in this section are considered.

Note: Ladders are potentially dangerous. The most common type of accident

occurs through a ladder slipping.

5.4.1 Transporting and Moving Ladders

Unless space restrictions dictate otherwise, always carry ladders parallel to the ground.

Do not move, shift, or extend a ladder while the ladder is occupied.

Note: Do not walk under a ladder

Tie ladders down securely when transporting.

5.4.2 Maintenance

Ladders shall be inspected and maintained by a competent person. The record of inspections

shall be registered and not be longer than six months.

Keep ladders free of oil, grease, and other hazards.

Do not use any ladder with structural defects; properly tag the ladder with a "Do Not Use"

notice, withdraw the ladder from service and quarantine it.

5.4.3 Preparation

Inspect ladder prior to EVERY use.

Before using a ladder, ensure that it is the correct item of equipment for the job in hand and

that it is in good condition

Warning: Aluminium ladders must not be used in hazardous areas due to the

danger of sparks when the ladder impacts steel).

Use ladders only for the purpose for which they were designed (refer to manufacturer's

labelling and recommendations).

5.4.4

Safe Use of ladders



Always place a ladder on a firm base, set the angle to 68 (1:4), or 75%.



Make sure the ladder projects well above the level at which the user stands.



Ensure sufficient overlap between stages of extension ladders.



Secure the ladder in place wherever reasonably practicable.



A standby person should remain at the base of the ladder whenever the ladder is

in use.



Barricade traffic areas in vicinity of ladder use, and lock, barricade, or guard

doorways in which a ladder is placed.



Keep area around the top and bottom of ladder clear.



Use only non-conductive side rails around live electrical equipment.



Do not use top or top step for standing/stepping.



Do not stand on cross bracing.



Always face the ladder when ascending or descending.



Always maintain 3 points of contact with the ladder (2 feet/1 hand or 2 hands/1 foot

should be in contact with ladder at all times).



Carry tools in zipped or closed pouches around waist; use a rope to raise or lower

large items such as tool boxes or materials.



Do not overextend sideways. Use the belt buckle rule: keep your belt buckle

positioned between the side rails at all times, which will maintain your centre of

gravity.



Never allow more than one person on the ladder at a time.



Do not erect ladders on sloping surface, leaning to one side or at too steep an

angle.

Do not erect ladders for use as a board or bridge.

Procedure for Task Risk Assessment

Page 5 of 34

3.1

LEGISLATION & STANDARDS

The aim of this Safe System of Work is to achieve ”no accidents”, “no harm to people” and

“no damage to the environment”. To achieve this aim, this SSOW complies with National

Legislation, the terms of the Production Sharing Agreement (PSA) and mandatory BP

Standards.

The best International Oil Industry practice and relevant goal setting legislation have been

adopted to reduce the level of risk to as low as reasonably practicable and therefore well

below that mandated by applicable statutory laws and regulations.

In the absence of local regulations, BP Group Standards will apply. In addition,

appropriate UK and US regulations and industry best practice have been considered in

setting suitable goals and targets.

3.2

COMPANY REQUIREMENTS

It is a company requirement that all tasks are subjected to an assessment of risk to

demonstrate that risks have been reduced to as low a level as reasonably practicable

(ALARP). This can be achieved by complying with the Company‟s existing standards.

Where compliance with Company standards cannot reasonably be achieved, a formal

level

2 Risk Assessment will be undertaken to identify any additional controls and

demonstrate that risks remain as low as reasonably practicable.

3.3

STOPPING UNSAFE WORK

To stop the continuation of potentially unsafe work at the earliest possible stage, the

Control of Work (CoW) Procedure and this Task Risk Assessment procedure make it very

clear that all personnel are obliged and have the obligation to “STOP” the work that they

consider to be unsafe.

4.9.1 RECORDS

Records of attendance and competency will be filed for future reference / verification by

(preferably in electronic format).

RISK ASSESSMENT LEVELS

The process of Task Risk Assessment (TRA) is a method for systematically examining an

individual work assignment (task), to identify the hazards, evaluate the risks and specify

appropriate controls.

There are 2 levels of risk assessment defined within the process:

Level 1

Level 1 is a broad overview of the task by a Area Authority (AA) (typically the Team

Leader and the Performing Authority (PA) to identify any hazards involved and appropriate

control measures which are required to be in place to allow the job to proceed.

Level 2

Level 2 is a formal assessment, which is required only when the AA‟s judge that there are

greater hazards or complexities associated with the task, which requires a more rigorous

level of assessment. A team of minimum 2 personnel carries out this assessment.

All Risk Assessments require input from those who will be doing the work. In addition,

some Level 2 Risk Assessments may require the input of expertise from outside the

normal site / installation team.

Previously carried out L2 Risk Assessments (L2RA) can be used for repeat tasks.

Note: Whenever a previous L2RA is re-used then it is critical that the details of the TRA

are reviewed to ensure that the scope of the task is still relevant, conditions have

not changed and that the hazards and control measures are still appropriate. A

new L2RA Front-Sheet must be completed, to capture details of the new review

team. If conditions have changed, the TRA should be reviewed, revised and

approved before it is re-used.

5.1

LEVEL 1 RISK ASSESSMENT GUIDANCE NOTES

A Level 1 Risk Assessment is based on section 1 and 2 of the Permit. The Permit Form

provides the prompt list and structured approach for this level of Risk Assessment.

Different Permits have different prompt lists in section 2.

A Level 1 Risk Assessment involves a review of the task by the PA in consultation with the

Area Authority to identify the hazards associated with the task and appropriate control

measures required to manage these hazards. The PA‟s in using their technical

competence and task information from section 1 selects the hazards from a list.

The PA then uses the controls listed in section 2 of the Permit to show how the work will

be controlled.

These hazards and controls are selected from a list from the permit, although the PA

should not be constrained by this and must use his judgement and expertise to identify

any further hazards or controls - there is space on the permit to add additional hazards

and controls.

The Area Authority must decide whether the risks can be controlled adequately by the

proposed means, taking into account the controls required by any relevant local procedure

and the competence of the person in charge. If the Area Authority is not completely

assured that the risks will be adequately controlled by these measures and feels a more

rigorous assessment is required, they must inform the person in charge of the work and

request a Level 2 Risk Assessment. This requirement should ideally be identified at the

earliest opportunity. The Site Manager / Site Controller / Offshore Installation Manager

can direct that a Level 2 Risk Assessment shall be undertaken at any time. Earliest

communication of the task requirement and discussion about it will identify the level of

Risk Assessment process to be conducted.

The Area Authority will review with the PA Section 1 and 2 of the permit along with any

documentation. They will visit the worksite to confirm all hazards have been identified and

controlled.

The flow-path that should be followed is provided in Appendix D.

Note: Discussing the job with the workforce involved is an important part of this process.

5.2

LEVEL 2 RISK ASSESSMENT GUIDANCE NOTES

A Level 2 Risk Assessment must be carried out at any stage in the process where the PA,

AA, a member of management or any other personnel believes that significant risks exist

which will not be adequately controlled without a more rigorous assessment and the

application of additional controls. This requirement should ideally be identified when the

planning for the task is first initiated. The AA is responsible for making a decision whether

a L2 RA is required.

Procedure for Task Risk Assessment

Page 10 of 34

The reasons for a Level 2 Risk Assessment might include, for example:

 The task is new and unfamiliar

 It is physically impossible to comply fully with the standards in a relevant local

procedure or other recognised source of guidance

 Previously used controls may not be reasonably practicable in this case

 The task is complex and/or has potential impact on other activities

The decision on when a Level 2 Risk Assessment is required for a task is somewhat

subjective and will depend on the people involved, but the following rules should be

applied to ensure a consistent level of assessment is being carried out across the

organisation.

There are five types of Level 2 Risk Assessment:

 Normal

 Operational Risk Assessment (ORA)

 Stand Alone Risk Assessment (SARA)

 Isolation Risk Assessment (IRA)

 Safety Overrides Risk Assessment(SORA)

A Level 2 Risk Assessment is mandatory for any job described in Table 1 below.

5.3

NORMAL LEVEL 2 RISK ASSESSMENT

Tasks identified in this section require a Normal Level 2 TRA to be performed. In the event

a particular task is not listed but the Task has a significant risk then a Line Supervisor

should be consulted. Some sites may have specific activities unique to that site which they

deem as mandatory Level 2 tasks, that has to be reflected in the local rules. A Level 2

Risk Assessment must always be undertaken for any job, which requires:

 Confined Space Entry

 Introduction of new Marine Vessels whether

owned, operated or chartered into operation

 Work on flare systems

Some sites / installations will have standing instructions or procedures in place covering

standard precautions for some of these activities. They can act in support of the

assessment and may adequately cover most of the required control measures.

The flow-path that should be followed is provided in Appendix D.

5.3.1 OPERATIONAL RISK ASSESSMENT

Operational Risk Assessments (ORAs) are associated with a piece of equipment or plant

as opposed to being associated with a specific task. They involve going through a similar

process as for raising a WCC Permit or Routine and require carrying out a Level 2 Risk

Assessment and identifying some control measures that need to be put in place.

Examples of ORA are:

 Operating a compressor with some executive action instrumentation out of service

(e.g. vibration probe), where some additional controls or monitoring is required to

allow continued operation of the compressor

 If any part of a Safety Critical Element does not meet its performance standard.

 To override a trip function, unless approved by operations procedures.

 Reduction of deluge cover in an area of the Installation where some additional

controls or restriction on work would be applied to that particular area of the plant

 Problem with a lifeboat where some alternative evacuation arrangements are in

place

Content of Operational Risk Assessment

The ORA shall describe:

History

The ORA shall describe the context of the situation surrounding the requirement for the

ORA. Include explicit description of equipment involved - tag numbers etc.

Consequence

The ORA shall describe the consequences of operating in accordance with the ORA.

This will include a statement of the value (1 to 15) of highest residual risk depicted in the

Level 2 Risk Assessment Matrix (refer to Paragraph 5.7.1) and a description of the

impact on integrity or safety of this change from normal condition.

Page 12 of 34

Justification

The ORA shall include a statement describing why the risk of operating in this way is

As Low As Reasonably Practicable (ALARP)

The team may need to refer to discounted alternatives to demonstrate ALARP.

Note: ALARP is the point at which the potential risk has been reduced to where any

additional reduction will be outweighed by the cost or effort that will be incurred. (Click the

Link for more guidance).

Plan to Resolve

The ORA shall include a description of the duration and the planned actions to resolve the

need for an ORA. Furthermore it shall describe what actions are required in the event the

duration of the ORA is exceeded.

Duration of ORA

The duration assigned to the ORA is agreed within the risk assessment and reflects the

maximum acceptable duration, consistent with maintaining risks ALARP.

The maximum possible duration for specifically numbered ORA is 28 days. This is

different to the agreed acceptable duration for which the risk may be permitted to remain -

i.e. a shorter validity period can be stated, or another duplicate ORA generated after 28

days, if a longer duration is acceptable.

When ORAs result in the issue of a temporary eMoC they shall be cross referenced.

Approval of ORA

In addition to the normal ISSOW approvals the following engineering functional approval

is required:

 All process or equipment related ORA‟s shall be reviewed and approved as a

minimum by the relevant DRE in the AESTL team.

 For all ORA‟s with a risk ranking 8 and above a Technical Authority (TA) or

delegate shall endorse the ORA. In some instances more than one TA may be

required to review and endorse. In reviewing any individual ORA the TA shall also

consider the cumulative risk of existing ORAs.

 Anyone with actions assigned by the ORA shall countersign it to acknowledge that

they have read and understood the ORA.

 Prior to approval, the Site Controller shall consider the cumulative risk of the

proposed and existing ORAs.

 The Site Controller shall carry out a physical inspection of any associated

modification to equipment/worksite prior to approval of the ORA.

Note: In exceptional circumstances the Site Controller is delegated authority to approve

the ORA without engineering review, if the Site Controller is satisfied that the risks

accepted by the ORA have been reduced to ALARP. (Click the Link for more guidance).

In these circumstances, the ORA shall be countersigned by the relevant engineering level

within 3 days.

Operational Risk Assessment Review Process

 Any abnormal change to process or equipment shall trigger an immediate review

of all ORA‟s related to that system to ensure that the ORA remains valid.

 Weekly Review: A site led review to confirm that the ORAs are still valid and that

no changes are required. (This will normally be carried out at the daily PTW /

SIMOPS meeting) and the Sentinel Pro system will warn of the necessity to

review.

Re-Authorization / Reassessment (28 days max)

A site led review to confirm that the ORA is still required. The same approval process shall

be followed as for a new ORA, with confirmation that no additional controls are required.

To ensure history is maintained via the „view linked facility‟ the ORA that is due to become

out of date should be copied and then fully re-assessed by a suitable team (AA, discipline

expert) prior to submission the SM / SC / OIM for approval.

The Sentinel Pro software will alert personnel that a reauthorization is due.

Quarterly Review

All current ORA‟s shall be audited by AOM, as follows:

a. Assess and approve the cumulative risk to site (this should be ALARP).

b. Use a risk matrix to plot ORAs in order to assist with the assessment of risk.

c. Review progress to close out the ORA. Agree any changes required to action plan;

ensure that the priority of ORA close-out is consistent with Asset requirements and the

ORA residual risk.

d. All ORA‟s shall be logged as Audited (through the full cycle to SM / SC / OIM review

and any relevant findings logged in the audit report using the Sentinel Pro software)

e. Any actions arising from the quarterly audit shall be recorded in Traction.

5.3.2 STAND-ALONE RISK ASSESSMENT

SARA‟s are not task-related but once again require that a Level 2 Risk Assessment be

conducted. A Stand-Alone Risk Assessment involves carrying out a risk assessment,

which may not be associated with either a task or specific piece of equipment. It could for

example involve performing a risk assessment associated with a change in organisation

or responsibilities. It allows direct use of the standard Level 2 Risk Assessment process.

If a SARA is required, the procedure would be:

 Create a team as per L2RA procedure (Mandatory Level 2 Risk Assessment)



Complete a TRA on Front-Sheet and Work-Sheets(or ISSOW database for electronic

Permit to Work System users)

 Authorise SARA - register held by SM / SC / OIM

 Assign controls, and put in-place

A Stand Alone Risk Assessment has no restriction on validity duration, but should be

reviewed by the SM / SC / OIM every 28 days.

5.3.3 ISOLATION RISK ASSESSMENT

When an Energy Isolation-Process does not meet the standard as stipulated in Energy

Isolation procedure; AZSPU-HSSE-DOC-00049-2, a L2RA is required. The risk

assessment should only be on the isolation element of the task, and not the work task

element.

Examples of when an Isolation Risk Assessment (IRA) is required are:

 Sufficient number of valves are not available to achieve the level of isolation

required

 There is an integrity issue (e.g. leaking) of part of an isolation

 An alternative means of isolation must be resourced, i.e. stopple bag, ice-plug

 Complete TRA Front Sheet or ISSOW database for electronic Permit to Work

System users)

 The TRA Worksheet should identify controls to allow a safe and suitable isolation

 Authorise IRA - register held by SM / SC / OIM

 Assign controls, and put in-place

An Isolation Risk Assessment is valid indefinitely, however it has to be revalidated after 7

days by the SM / SC / OIM

5.3.4 SAFETY OVERRIDES RISK ASSESSMENT

A SORA is required for any of the following:

 Protective instruments with IL 1 or above.

 Riser valves; sub-sea valves; down hole safety valves

 ESDV‟s

 Yellow or Red Shutdown functions

Note: Even for routine tasks such as trip testing or sampling, SORA shall be required,

however a generic SORA may be prepared for repetitive tasks.

If a SORA is required, the procedure would be:

 Follow up RA process detailed in Procedure for: Control of Protective System

Overrides and Alarm Blocks (AZSPU-HSSE-DOC-00015-2) using attached form in

Appendix B

 Authorise SORA - register held by SM / SC / OIM (for Export Pipelines - Ops

Manager):

 Assign controls, and put in-place

5.4

LEVEL 2 RISK ASSESSMENT TEAM

The objective of the Level 2 Risk Assessment is to assemble a team of persons with

intimate knowledge and expertise of the task and in a structured way, examine all the

hazards associated with that task, and then devise a set of controls which will ensure an

acceptable level of risk is achieved. Where necessary, expertise from elsewhere

(e.g. specialist vendors/contractors) may also be brought into the assessment process.

Where larger jobs or shutdowns are planned, work should be undertaken early on to

identify potential tasks requiring Level 2 Risk Assessments in order to allow adequate time

for the assessment to be undertaken.

The Level 2 Assessment Team shall be made up of a minimum of two persons and

consist of persons having intimate knowledge and experience of the task or equipment to

be used.

Note: There should be a fully competent TRA Leader (Area Authority) capable of acting

as facilitator and leader of the assessment process.

The TRA Team Leader should make arrangements for the team to work as a group. It is

important to ensure, for example, that there is adequate space for examination of

drawings and that sufficient time is allocated to allow a rational decision to be reached.

It should not normally require more than a team of five persons to carry out an

assessment.

The objective of a Level 2 Risk Assessment is to use local knowledge and specialist

knowledge in a structured way in order to achieve ALARP for any residual risk.

The Risk Assessment team should include:

 The Area Authority for the area in which the task will be carried out, who will act as

TRA Team Leader

 The Performing Authority

 The person who will undertake the task

 A specialist from inside and external to the operation as required

Note: An HSE specialist involvement may be required to ensure that the Risk Assessment

is carried out in accordance with this procedure and for recording the results.

Note: a L2RA Team requires at least two members.

5.5

THE STAGES OF RISK ASSESSMENT

5.5.1 DEFINING THE TASK TO BE ASSESSED

The task description detail must provide information on Who, What, Why, How and When

the task will be performed. As the task becomes more complex the level of detail and

supportive documentation required will increase. The level of information provided must

take into account all people taking part in the task.

The Task Risk Assessment team must first ensure that they fully understand the task and

its implications. The overall task may need breaking into steps to facilitate carrying out the

Task Risk Assessment. When defining the task, think about such aspects as:

Item

Issues to Consider

1. System boundaries

What is the system being worked on? The extent of

equipment, hardware, or software affected by the activity.

Will the work be carried out on isolated or un-isolated

systems? Where are the isolations, or interfaces with other

systems?

2. Area or space boundaries

What area is affected by the activity?

What area could be affected in an accident?

3. Work activities included

What do you have to do? What might be the effect of doing

it? Think about isolations, inhibits, etc.

4. People affected

People; in the team, working nearby, who might be passing

by, working on related activities and working on connected

systems.

5. Time and duration of work

Will the task take one hour or multiple shifts?

Will the work be done during the day or night or both?

6. Tools and equipment to be used

Does the activity require hand tools, power tools, ladders,

lifting equipment, etc.? Task-specific PPE

7. Interfaces with adjacent work-

How will your work affect other work going on at the same

fronts

time? How will other work affect you?

assess the layout of the area, site conditions and adjacent plant and activities. Once the

members are all familiar with the scope of the task to be carried out, the team should list

all the significant hazards in column 3 of the TRA worksheet. For a L2RA these are

identified on the permit.

Checklists are supplied as a guide for reference purposes only. They should not be

considered as being comprehensive. A group brainstorm, with the team leader making

sure that each member is given adequate opportunity to express their views is vital to

maintain a systematic approach to using these checklists. See Appendix A

Note: ISSOW database, where RA recorded has got different layout (See attached Link)

5.6.1 IDENTIFYING THE HAZARD EFFECTS

Note: Recording of the Hazard effects is only recorded on a L2RA. However the hazards

effects should be considered on any type of Risk Assessment.

The Team shall then identify the Hazard Effects, which will be entered into column 4 of the

L2RA Work-Sheet. Hazard effects are the worst credible possible outcome of the hazard.

The Team should be as explicit as possible in the Hazard Effect details. It is important to

consider property damage and environmental impact and not just personal injury.

5.7 EXISTING CONTROL MEASURES

Note: Existing Control measures are valid for both L1RA and L2RA.

When doing a risk assessment, it is normal to assume that no controls are in place. For

many tasks, some controls may be known before the risk assessment, and it is not

realistic to think of the work being done without these controls (e.g. an energy isolation).

So, if experience or normal industry or trade standards dictate, it may be valid to assume

that certain controls are in place, provided that:

 They are stated in column 5 of the L2RA Work-Sheet

 They are demonstrated as part of the task definition (e.g. planned isolations must

have appropriate isolation certificate and marked-up P&IDs); and

 The controls are confirmed to be in place prior to the work being carried out

Controls that may be included in the definition of the task include:

 Procedures, operating guides, etc. (supported by a valid risk assessment);

 Energy isolations confirmation certificate (including P&IDs)

 Entry certificate

 Scaffolding request; and

 Other risk assessments such as, manual handling, LSA/NORM scale.

Work permits are used for recording the controls for individual work tasks, for controlling

the interfaces between work activities and to gain the correct approvals to start a job.

However, a work permit itself is not a control for an individual work task and should

therefore not be included in the task definition.

Note: ISSOW database, where RA recorded has got different layout (See attached Link)

5.7.1 EVALUATE THE RISK

Note: Recording of the Risk value is only recorded on a L2RA. However the risk factors

should be discussed for a L1RA.

The risks created by each hazard on the list should be evaluated according to:

 The worst credible severity of the hazard effects, should anything go wrong

 The probability of the hazard being realised and resulting in the specified hazard

effect

It is important to consider property damage and environmental impact and not just

personal injury. For each hazard the initial hazard effect and probability are defined based

on the Risk Assessment Chart shown in Appendix B.

Probability Guidelines:

PROBABILITY

RATING

Event likely to occur more than once per quarter

HIGH

(FREQUENTLY)

(H)

Event likely to occur at least once per year, but less than a quarter

MEDIUM

(PROBABLE)

(M)

Event likely to occur less than once per year

LOW

(OCCASIONAL)

(L)

The hazard effect (E) and probability (P) are then used to determine the risk (R), using the

risk matrix provided. The E, P & R values are written in column 6 of the TRA worksheet.

The effectiveness of the assessment will depend entirely on the team‟s ability to identify

and evaluate all hazards associated with the task. The team should also consider the

possibility of the interaction of different hazards, including those related to:

 Location - Attention should focus on the proximity to other plant or equipment, e.g.,

air intakes, shut down systems, control points, vents, drains, sample points and

ignition sources.

 Critical Activities

- Critical activities include isolation, flushing, inerting, confined

space entry; work at height, hot work, lifting, use of power tools, temporary power

and air supplies, pressure testing, radiography.

 Simultaneous Activities. - Simultaneous activities should be investigated both within

the task itself and with other unrelated activities taking place nearby.

5.7.2 DETERMINING THE ADDITIONAL CONTROLS REQUIRED

Note: Recording of the Additional Controls is only completed on a L2RA column 7.

Recording of Controls for a L1RA is in section 2 of the permit.

Once the initial Assessment of Risk is complete, the team must work systematically

through the list of Hazards and specify all the Additional Control Measures needed to

mitigate each associated Risk. These are recorded in column 7 of the TRA worksheet.

Note: Controls, which prevent the hazard being realised, should be used in preference to

controls that reduce the effect of a hazard.

The hierarchy of controls is applied in the following order:

1. Eliminate

2. Reduce (substitution, Engineering, Segregation)

3. Manage or Administration (reduce exposure, Procedures)

4. PPE - This must be the last control applied; remember that with PPE you are inside

the hazard zone.

Wherever possible, measures higher in the hierarchy should be used, providing they are

reasonably practicable, and emphasis should be placed upon control at source. A

combination of measures will usually be necessary in order to reduce the level of Risk to

As Low as Reasonably Practicable (ALARP). It should also be considered that when

specifying controls, any associated risk that they bring with them needs to be assessed

and controlled.

Activities such as confined space entry (ground disturbance and etc.) supported by task

risk assessments shall identify the credible potential emergencies that could occur during

the work with response and rescue plans being in place before the work commenced.

Typical Control Measures can be placed in the following categories:

Control Measure

Typical Examples

Physical

Removal of fuses; Insert spade or blank flange in pipe work; Lock off

valve; Erect mechanical barrier; Use locked enclosure; Keep people at a

distance (e.g., signs, warning tape); Eliminate or substitute toxic

substances; Substitute noisy machinery; Use mechanical handling

equipment.

Procedural

Test for pressure build-up or leaks; Examination of flushing fluid; Test for

hazardous chemicals in liquid, solid or gaseous form; Procedure for

control of simultaneous or adjacent work; Prohibition of hot work;

5.7.3 ALLOCATING RESPONSIBILITIES FOR CONTROL ACTIONS

Note: Recording of the Responsibilities is completed on a L2RA column

Responsibilities for control actions are not recorded on a L1RA, but can be

identified in a method statement or procedure.

Once the control measures have been identified, each should be allocated to either an

individual or a role. The Risk Assessment may be completed some time before the actual

work task-taking place; therefore the delegated individual / role may change. Where

possible, identify both a role and a specific individual. These are recorded in column 8 of

the L2RA Work Sheet.

Column 11 is for recording the closeout of the actions. Therefore this column should not

be completed until the work is about to commence.

Note: ISSOW database, where RA recorded has got different layout (See attached Link)

5.7.4 RE-EVALUATE THE RISKS FOR ACCEPTABILITY

Note: This is completed on a L2RA column 9. Risk re-evaluations are not recorded on a

L1RA (permit).

The team must then re-evaluate the risk for all those hazards for which controls have

been determined. The new risk level should be determined and the team should consider

whether the risk is now as low as reasonably practicable (ALARP). Column 10 should be

identified with a „Y‟ to confirm the Risk Analysis Team has agreed ALARP.

If the risk is not ALARP, the review team must decide what further safeguards need to be

put in place. The agreed residual E, P and R are recorded in column 9 of the TRA

Worksheet.

The team must finally decide on the acceptability of the overall remaining risk for the task.

Individual hazards with a medium risk may be acceptable provided the overall risk of the

task is considered low. If the team decides that even with the controls in place, there are

too many hazards, which still have a medium risk, this must be recorded and the task in

its present form must be abandoned.

The higher the perceived risk for any particular hazard, the greater should be the

number and/or quality of independent controls, which the team specify as necessary.

Consideration should also be given to the possibility of cumulative effects from the

interaction of several different hazards.

Page 21 of 34

If the team considers that there are insufficient independent controls available, or that the

controls are likely to be ineffective against any particular risk, that risk must be judged to

be unacceptable, and the team leader must record this decision. The task must then be

abandoned or referred to higher management.

The team may also conclude that because of the complexity or degree of the risks

involved, a more detailed engineering assessment is needed. In this case, the task must

be suspended until the assessment is available.

As a final check, the team should ask itself the following questions about the

proposed task:

 Have all necessary control measures been fully and effectively identified?

 Is there a need for engineering change to eliminate or reduce risk further?

 Is there a need to shutdown the plant or process?

 Is the residual risk rating acceptable?

 Is there anything else that can be done to further reduce the risk?

Only at this point can the team judge whether ALARP has been achieved.

This Table gives guidance for the residual risk criteria:

Take immediate action if standards are not met.

Ensure additional controls are implemented.

2 to 5

Implement control measures to reduce the risk to the lowest level

reasonably practicable.

Prepare a plan to reduce the risk to the lowest level reasonably

practicable.

5.7.5 IMPLEMENTATION OF CONTROL MEASURES

Note: Recording of the control implementation is completed on a L2RA column 11.

Implementation of controls is not recorded on a L1RA.

Column 11 is for recording the close-out of the actions. Therefore this column should not

be completed until the work is about to commence.

There are two types of control measures that will be identified from either the Level 1 or

Level 2 TRA process:

 Prerequisite controls are those which must be in place prior to the job starting

Page 22 of 34

 Supplementary controls are those which have to be applied during the job

The prerequisite control measures must be implemented prior to the job going live. This

includes any training and/or special briefing of the PA and work party according to an

agreed plan of action.

The supplementary controls, which will be applied during the job, must be understood fully

by the PA and the work party before work commences.

The AA must satisfy himself that Competent Persons have been allocated the work;

the required controls are in place, any additional paperwork is complete, and that all

the individual risks are reduced to ALARP.

5.7.6 TASK INSPECTION CHECKLIST

In order to ensure that workers are made aware of the hazards and control measures of a

particular task, checklists should be prepared. The checklists are based on the control

measures identified in the TRA and for use by site / installation supervisors/safety officers

during toolbox talks and site inspections. An (example) checklist is shown in Appendix F.

5.7.7 TOOLBOX TALKS

Note: Toolbox talks will be carried out for all tasks, whether they are L1RA or L2RA.

This is the process of transferring the methodology and controls to the people who will

carry out the work. It is vital that all persons involved in working on a particular activity are

fully aware of the details of the TRA and all the hazards and controls associated with the

job. Some of them may have been directly involved in the TRA but others may not have

been. This is particularly true of larger jobs (e.g. construction) where the PA who is

normally the Construction Supervisor will have been directly involved in the TRA but the

rest of the work party probably have not.

A Toolbox Talk is a vital part of the process to ensure that the TRA and its associated

documents are reviewed prior to the start of the job and are fully understood by all

persons involved in the task.

Particular emphasis should be placed on those residual risks with a higher rating. It is also

an opportunity for those involved in the work to raise any further concerns about the job

and to identify any hazards not picked up in the TRA process.

It is crucial to the people involved in the task execution to fully understand the TRA.

Therefore, where English is not the first language for the work team, a quality translation

to appropriate languages must be made available to the team before work starts.

Note: If anyone at this stage identifies some additional hazards that have not been

properly assessed or thinks the control measures are inadequate, then the job should not

proceed until the TRA has been re-evaluated and appropriate controls identified to ensure

the job is ALARP.

Keys to the success of this step are:

 Communication of the task, the hazards and what must be done to control them to

every person involved in the task.

 Language is critical, especially in complex technical tasks.

 The toolbox talk is held prior to work starting

 Everyone understands everything discussed

5.8

MANAGEMENT OF RISK

5.8.1 APPROVAL

On completion of the Risk Assessment, the Risk Assessment Front & Work Sheets must

be attached to the permit application for the job. It must be reviewed and signed by the

SM / SC / OIM before he approves the associated Permit(s) to Work.

Should the SM / SC / OIM feel that the task presents risks beyond his level of

accountability, he must refer to his Manager for guidance, and if necessary request a

more sophisticated analysis of the risks and mitigation than can be provided by the

method described in this procedure.

5.8.2 RECORDING THE RISK ASSESSMENT

Where a task is likely to be repeated, a record of the Risk Assessment should, at the

permit issuer‟s discretion, be retained for future reference. In any event Risk

Assessments, which include hazards to the health of those undertaking the task must be

attached to the permit(s) for the job and retained for 12 months.

Note: ISSOW allows you to track past records.

Where a Risk Assessment form is being re-used, it must be fully reviewed and a new front

sheet created.

PURPOSE

This procedure specifies the requirements necessary for the safe procurement, handling, use,

storage, and transportation of gas cylinders for compressed gases and gases liquefied under

pressure.

1.2

SCOPE

The contents of this procedure are applicable to all BP owned and managed sites / installations

in Azerbaijan and Georgia. Contractors working on BP owned or managed sites

installations are also responsible for alignment with this procedure.

This document does not replace the procedures prepared and adopted by specialist

Procurement Supply Chain Management

3 GENERAL REQUIREMENTS

3.1

LEGISLATION & STANDARDS

- Operating Management System OMS Essentials 3.2.1 and 4.5.1

This procedure complies with applicable national law. Applicable national law is national law as

amended by project specific agreements, e.g. the ACG Production Sharing Agreement (PSA),

and relevant International Conventions, if any, in force in Azerbaijan or Georgia, as applicable.

In the absence of national legislation, or where national legislation is inconsistent with the

requirements of project specific agreements, BP Group Standards or applicable requirements

from UK or US legislation will be complied with.

Where requirements conflict, legal advice has been obtained and a defendable compliance

position adopted.

The standards and practices contained in this procedure are consistent with those

internationally recognized within the petroleum industry.

3.2

COMPANY REQUIREMENTS

It is a company requirement that all tasks are subjected to an assessment of risk to

demonstrate that risks have been reduced to as low a level as reasonably practicable (ALARP).

This can be achieved by complying with the Company’s existing standards. Where compliance

with Company standards cannot reasonably be achieved, a formal level 2 Risk Assessment will

be undertaken to identify any additional controls and demonstrate that risks remain as low as

reasonably practicable, whether by compliance with Company Group Standards or through

level 2 Risk Assessment.

3.3

STOPPING UNSAFE WORK

To stop the continuation of potentially unsafe work at the earliest possible stage the Control of

Work (CoW) Policy and this Procedure for Transportable Compressed Gas Cylinders make it

very clear that all personnel are obliged and have the authority to “STOP” the work that they

consider to be unsafe.

3.4

DEVIATIONS

This procedure is written in sufficient detail that it should be able to be applied consistently at all

sites / installations. There may still be the requirement for some local rules covering site /

installation specific logistical

administrative arrangements and local variations in

responsibilities to reflect differences in organisational arrangements. These local rules should

not deviate from the core processes within this document. Any form of deviation from this

procedure, including but not limited to local rules, shall be requested and authorised in

accordance with SSOW Procedure for Deviations (Doc. No: AZSPU-HSSE-DOC-00011-2).
