Alarm Disabling

The key tool available for the management of alarms in real time is the ability to

disable (and subsequently re-Enable) individual alarms to meet short-term needs

(for example the alarm is ‘bouncing’ due to unusual operating conditions).

Application of Alarm Disables

Application of alarm disables will be the responsibility of the PA.The PA will also be

responsible for updating of the Disables register, and shall make reference to

reasons why the Alarm disable has been applied. The RP shall review the register

and sign the review log at every shift handover.

Removal of Alarm Disables

Alarm Disables should be removed from the systems as quickly as possible, when

the reason for application has been resolved

Audit of Alarm Disables

Audit of alarm disables, shall be carried out on a weekly basis. A suitably qualified

and competent person, designated by the OIM/Site Controller, shall conduct this

audit. In addition to this there will be an Annual review of the performance of the

Alarm System, and identification of agreed improvements to be worked.

 facilitating formal health monitoring and screening of all personnel involved with

asbestos related activities

 providing advice and assistance in the setting-up of Asbestos Hazardous Areas,

and the atmospheric monitoring of those areas.

2.5

All Personnel

All personnel are responsible for:

 reporting any suspected asbestos or asbestos-containing material to their

immediate supervisor.

 the correct, conscientious and responsible use of all personal protective

equipment with which they are supplied, including respiratory equipment

 halting and reporting to their supervisor any work they consider to be unsafe.

2.6

Consultants / Specialist Contractors

The handling and removal of asbestos will usually be carried out by an independent

contracting company with the necessary specialist knowledge and experience.

Companies contracted by BP to work on asbestos related activities are responsible for

carrying out their work on BP sites and installations in accordance with the

requirements of local legislation.

In addition, contracting companies and their personnel shall be required to provide

evidence of their relevant expertise and knowledge, and their ability to work safely with

asbestos, whenever required by BP.

Asbestos Hygiene Standards and Air Monitoring

3.1

Occupational Exposure Limits

The occupational exposure limits included her shall be applied to all types of asbestos

in all locations where asbestos exposure is not otherwise subject to legislative control.

The following exposure limits apply to air samples taken from the breathing zone by

suitably qualified personnel.

Exposure Limit = 0.2 fibres/ml, 8-hour time weighted average

Action Level = 0.1 fibres/ml, 8-hour time weighted average

These limits do not represent ‘safe’ and ‘dangerous’ conditions as they cannot be

guaranteed to avoid all risks to health. Therefore, exposure should be reduced to at

least these limits and preferably as far below them as reasonably practicable.

In particular it should be noted that the interpretation of any atmospheric monitoring

results should only be undertaken by suitably qualified, trained, and experienced

personnel. The use of specialist contractors for this task is strongly recommended.

3.2

Clearance Standard

Where asbestos work has been carried out in an Asbestos Hazardous Area (see

Paragraph 5 Asbestos Hazardous Areas) the area shall not be returned to unrestricted

or normal use until the ambient fibre concentration no longer exceeds the Clearance

Standard:

Clearance Standard = 0.1 fibres/ml.

Note: The Clearance Standard should only be regarded as a transient indication of

cleanliness following completion of asbestos related activity.

3.3

Air Monitoring

Note: The collection and analysis of air samples shall only be carried out by

personnel who are properly trained and knowledgeable in air monitoring

techniques. The use of specialist contractors or consultants for these tasks

is strongly recommended.

Airborne fibre monitoring (see Appendix B) shall be carried out:

 during all work involving the removal of asbestos

 damaged or friable asbestos is present.

Air monitoring (personal sampling - see Appendix B) shall be carried out wherever

and whenever it is known or suspected that asbestos dust is likely to be generated.

The purpose of air monitoring is to:

 ensure compliance with asbestos hygiene standards

 check the effectiveness of control measures

 confirm the appropriate level of personnel protective equipment is in use.

Managing asbestos

In order to manage asbestos safely it is necessary to be aware of the:

 location of the asbestos

 form of the asbestos (lagging, ceiling tiles, partition board, etc)

 condition of the asbestos

 type of asbestos (blue, brown, or white).

Locating and Monitoring Existing Asbestos

If asbestos or asbestos-containing material is in good condition and unlikely to be

damaged, the safest and most pragmatic option is often to leave it in place. For

example, asbestos-containing building materials (floor tiles, felts, mastics, insulating

board, etc) may be present in buildings used but not owned by BP.

Asbestos-containing material that is left in place shall be recorded and regularly

monitored for any sign of deterioration.

Arrangements shall be made to alert personnel to the presence of asbestos, either by

clearly labelling the material or by briefing and informing all personnel who might work

on the material or in its vicinity.

Note: Even when all known asbestos has been removed or recorded, other hidden

asbestos may still be present.

4.2

Asbestos Register

Where asbestos is known to exist on-site, an Asbestos register should be established

and maintained in order to record the location and type of asbestos and to ensure that

the asbestos is regularly monitored for condition. The register should include instances

where materials that have been thought to asbestos containing materials but have

since been proved otherwise in order to prevent confusion. See also Appendix C

Asbestos Register Form.

4.3

Assessing the Condition of Asbestos

The condition of the asbestos or asbestos-containing material shall be assessed by a

suitably qualified and experienced person knowledgeable in the subject. In general a

risk of asbestos being released into the air shall be expected if:

 the material is being disturbed or if it is prone to accidental damage

 the surface of the material is damaged, frayed or scratched

 surface sealants are peeling or breaking off

 the material is becoming detached from its base

 protective coverings for the asbestos are missing or damaged

 there is asbestos dust or debris in the immediate surrounding area.

Asbestos or asbestos-containing materials, suspected or otherwise, displaying any of

the above conditions will require the area to be sealed off to form an Asbestos

Hazardous Area and an air-monitoring programme introduced.

4.4

Identifying Asbestos and Asbestos Types

Asbestos Types

There are three types of asbestos:

 crocidolite (‘blue’ asbestos)

 amosite (‘brown’ asbestos)

 chrysotile (‘white’ asbestos).

Although blue and brown asbestos are considered to be the most hazardous of the

three, all asbestos is dangerous and should be handled with care.

Sampling and Laboratory Analysis

Asbestos cannot be recognised by its visual appearance alone. Nor can the asbestos

types be identified solely by colour. A full laboratory analysis is required to identify any

substance as being asbestos and to distinguish its type.

Wherever asbestos or asbestos containing material is suspected, arrangements shall

be made for samples to taken and sent for laboratory analysis.

Sampling shall only be carried out by suitably trained, qualified and experienced

contract personnel or consultants who specialise in dealing with asbestos.

Warning: Do not break or damage material that may contain asbestos, even when

attempting to identify it.

Working with asbestos

5.1

Risk Assessment and Permit to Work

All work involving asbestos shall be carried out under the Permit to Work system and

must be supported by a formal Risk Assessment

A formal Risk Assessment, completed by a suitably competent person, shall be carried

out before any work involving asbestos or asbestos-containing material may take place.

The Risk Assessment must identify and address:

 the type(s) and locations of asbestos

 the nature and the extent of the proposed work

 the expected exposure levels for personnel involved in the work, including:

o whether exposure will be intermittent, exposure frequency and duration

o potential exposure level of personnel not involved in the work

o any existing air-monitoring results which may be relevant.

 measures required to prevent or control the release of asbestos into the

workplace or general environment

 any other hazards, not necessarily asbestos related

 emergency and contingency plans

 asbestos removal procedures, including:

o route selected for transferring asbestos waste through the site

o temporary storage of waste on site

o ultimate disposal of waste.

Note: In the case of small-scale maintenance, a documented Risk Assessment may

not be necessary.

5.2

Asbestos Hazardous Area

Whenever it is reasonably foreseeable that an operation may give rise to airborne

concentrations of asbestos in excess of the Action level, the area involved shall be

designated an Asbestos Hazardous Area.

Enclosure

The asbestos work area shall be enclosed completely to contain any airborne asbestos

fibre. To minimise contamination and to reduce interference with process plant, the

enclosure area will be kept as small as possible. If work is to carried out over a large

area, the area should be divided into smaller enclosures that are more easily

manageable.

Access to and from the area should be designed to prevent the escape of asbestos

dust as personnel pass through. Ideally, an ‘airlock’ system should be used.

Negative Air Pressure

Air extraction equipment should be incorporated within the enclosure to maintain a

slightly negative air pressure so that any leakage will be of clean air inwards.

Decontamination Facilities

Adequate vacuum cleaning, changing and showering facilities should be provided to

enable personnel to decontaminate themselves before leaving the work area.

Control of Access

The area shall be isolated and access denied to all unnecessary and unauthorised

personnel and also any personnel not wearing the required respiratory and personal

protective equipment. Warning signs should be strategically placed informing personnel

of the hazardous area conditions and entry restrictions.

Dust Levels

Airborne dust levels shall be maintained as low as reasonably practicable through

regular and frequent cleaning using vacuum cleaners and wet-wiping only. Cleaning

procedures should also be established for cleaning the asbestos workers’

decontamination, toilet facilities and eating / drinking areas.

Note: Dry sweeping or any other method that may raise dust shall be prohibited.

Waste Disposal and Transfer

All asbestos waste, including vacuum cleaner contents, should be placed in suitable

and clearly labelled containers inside the asbestos hazardous area. Labelling should

clearly indicate ‘Asbestos Waste’ and, where material is of a dusty nature, ‘Do Not

Inhale Dust’.

Where ‘double-bagging’ is used, the waste should be placed within a red bag and

sealed. The outside of the bag should be vacuum cleaned or water sprayed before

being placed within a second, clear bag, preferably inside the asbestos hazardous area

airlock.

Bags should not be overfilled. Where the waste includes large, heavy or sharp objects,

different types of container should be used that are puncture and tear-proof.

Decommissioning

Following completion of asbestos work, the hazardous area shall be thoroughly

cleaned so that all visible traces of asbestos are removed. When cleaning is complete,

air monitoring shall be conducted to confirm that the atmosphere within the area does

not exceed the Clearance Standard (see Paragraph 3.2).

Storage and Disposal of Asbestos Waste

If asbestos waste is to be stored on site, it shall be placed in a clearly demarcated and

secure area, to which only authorised personnel shall have access. The waste shall be

transferred off-site inside a closed, secure skip or vehicle to an approved hazardous

waste disposal site, in accordance with company requirements and nation / local

legislation.

Note: The final disposal of asbestos shall be undertaken by a specialist contractor.

7 Health Surveillance

BP employees working within or near asbestos hazardous areas should be kept under

routine health surveillance in order to:

 ensure that they have adequate respiratory function and are fit to wear

respiratory protective equipment when working under adverse conditions

 allow early detection of lung fibrosis and removal from further exposure may

limit the progression of asbestos in some individuals.

Medical records, particularly when correlated with asbestos exposure data, may

provide important evidence in case of litigation. Review of these records may, in the

longer term, assist the evaluation of the adequacy of occupational exposure limits and

control measures.

Note: Health surveillance of asbestos workers should include pre-employment

examinations with periodic review during employment in asbestos work.

8 Record Keeping

In addition to that recorded in the Asbestos Register (see Paragraph 4.2), the following

information should be recorded:

 Identities of all workers involved in the handling or use of asbestos.

 Results of personal monitoring of occupational exposure to asbestos.

 Medical records for all workers subject to health surveillance.

This information should be retained-ideally until at least 5 years after each individual

concerned has died, in case it is needed in connection with claims for compensation

arising from the delayed onset of occupational disease. In practice, this means that

medical records should be archived for at least 30 (preferably 50) years after the

employee has left the Company, or until 75 years after their date of birth.

The following information should be retained for at least 5 years:

 Summaries of the results of area/fixed position monitoring.

 Records of examination and testing of local extract ventilation systems.

 Records of inspection/maintenance of respiratory protective equipment.

 Records of assessments of risks and precautions.

 Records of training given to asbestos workers.

Records and documentation relating to asbestos waste disposals should be retained

indefinitely.

APPENDIX A - DEFINITIONS

Amosite

Commonly referred to as brown asbestos, similar to crocidolite but with

slightly curly fibres when viewed under a microscope.

Asbestos

A group of naturally occurring crystalline silicate minerals with

characteristic long thin fibres capable of being split longitudinally to

create progressively thinner fibres. It is these fibres that, in airborne

form, can cause asbestos related diseases when inhaled.

Asbestos

Any material that has asbestos as a component. For example, some

Containing

cement products, floor tiles, insulation material and lagging, clutch and

Material

brake linings, etc.

Asbestos

An enclosed area set up to contain the spread of asbestos dust from an

Hazardous Area

area where asbestos related activity is being carried out.

Asbestos

A record of all occurrences of asbestos that has been left in place on-

site. The register should record the asbestos type, its condition and

inspection record.

Asbestos Related

Any disease attributable to the inhalation of asbestos dust. These

Diseases

diseases might not occur until 20 - 30 years after inhalation.

Chrysotile

Sometimes called white asbestos. Although this type of asbestos is

considered to be less hazardous than crocidolite and amosite, it still

connected with asbestos related diseases.

Clearance

The maximum level to which asbestos contamination of the atmosphere

Standard

must be reduced before an asbestos hazardous area may be returned

to normal use.

Crocidolite

Commonly referred to as blue asbestos. Under a microscope its fibres

are short and straight.

Maximum allowable personal exposure to all types of asbestos,

presently set at 0.2 fibres/ml 8-hour time weighted average

Specialist

A contractor, or consultant, specialising in working with asbestos. The company

Contractor

must be satisfied that the contractor is suitably equipped, trained, experienced

and knowledgeable for the asbestos related activities (air-monitoring, asbestos

removal and disposal, etc) for which they are contracted

APPENDIX B - AIR MONITORING METHODS

Air Sampling Methods

Personal Sampling

For determining occupational exposure to airborne asbestos fibres and compliance with

occupational exposure limits, only personal sampling provides valid results.

For personal sampling, a potentially exposed individual wears a lightweight sampling

pump with the sampling head located in their breathing zone.

Note: Although 'fixed position' sampling may be useful to determine the

effectiveness of process control and workplace measures, it is not suitable

for monitoring personal exposures

Airborne Fibre Monitoring

Airborne fibre monitoring techniques involve drawing a measured volume of air through

a membrane filter at a constant flow rate.

Following sampling, the filter is mounted on a glass slide so that the fibres collected

may be counted by using phase contrast optical microscopy.

Note: It is important not to produce a density of particles on the filter which is too

great to allow individual fibres to be counted. Except in the USA, a 'fibre' is

defined as a particle having a length to breadth ratio greater than 3:1, a

diameter of less than 3µ and a length greater than 5µ.

APPENDIX D - ASBESTOS RELATED DISEASES

Asbestos Related Diseases

Asbestos only poses a risk to health if asbestos fibres are released into the air where

they form a very fine dust which is often invisible to the naked eye. When inhaled, this

dust is capable of being deposited in the deepest regions of the lungs where they may

cause any of what are collectively known as asbestos related diseases for which there

is no known cure. These diseases include:

 Asbestosis

 Pleural Thickening

 Pleural Effusions

 Lung Cancer

 Mesothelioma.

Any of these diseases may be caused by either exposure to high levels of asbestos

dust, or repeated exposure to low levels.

Asbestosis

Prolonged exposure to airborne asbestos may lead to asbestosis, a collagenous

fibrosis of the lungs. Fibrosis leads to a progressive reduction in lung elasticity and

impairment of the gas exchange mechanism.

Early symptoms of asbestosis include breathlessness and coughing.

The disease may progress to cause severe disability and heart failure.

Pleural Thickening

Exposure to airborne asbestos fibres may cause thickening of the pleura, and glass-like

plaques in the membranes surrounding the chest cavity. Although these changes do

not usually cause any ill effects, widespread pleural thickening may restrict lung

expansion and cause breathlessness.

Lung Cancer

Exposure to airborne asbestos fibres is associated with an increased risk of lung

cancer. In particular, asbestos exposure and cigarette smoking act synergistically to

produce a much greater risk of lung cancer than would be expected from the sum of

independent risks from smoking and asbestos exposure.

Asbestos fibres can cause irritation of the pleura leading to rapid outpouring of fluid into

the pleural cavity, squashing the lung on that side. Although rarely life-threatening, the

sudden shortness of breath is frightening and urgent medical attention is required.

Mesothelioma

Exposure to airborne asbestos fibres, particularly crocidolite and amosite, may lead to

the development of mesothelioma, a cancer of the pleura and more rarely, the

peritoneum (the membrane lining the abdominal cavity). Mesothelioma may develop 20

or years after exposure to asbestos. It is also associated with other fibrous materials,

such as erionite (a naturally occurring mineral), and may occur in persons with no

known occupational exposure to asbestos or other fibrous materials.

Mesothelioma is always fatal.

Introduction

The purpose of this document is to define the Azerbaijan Business Unit standards and

expectations regarding diving and subsea operations within the AzBU. This document

specifies the minimum mandatory BP and/or contractor safety management system

requirements for diving and subsea operations. Compliance with this Safe System of

Work (SSoW) will ensure that the standards of safety on diving and subsea projects are

in accordance with BP getting HSE right and the AzBU safety management processes.

Safety Goals

The goal of this SSoW is to achieve no accidents, no harm to people and no damage to

the environment. To achieve this goal the SSoW complies with the following:

Internationally accepted good engineering practice, as required by the operating

Production Sharing Agreement (PSA) across the Business Unit

Diving and subsea industry standards and guidance

BP policies and expectations - What We Stand For

BP HSE management system - getting HSE right

Azerbaijan Business Unit Safe Systems of Work

Expectations

The expectations of the SSoW are to:

Comply fully with all legal requirements.

Provide a secure and safe working environment.

Ensure that all employees, contractors and others are well informed, well

trained, engaged in and committed to the HSE improvement process.

Provide assurance that the safety processes in place are working effectively.

Maintain confidence in the integrity of BP operations.

Confirm that the management systems of contractors fully support BP’s

commitment to HSE performance.

Scope

This SSoW applies to all inshore or offshore diving and subsea operations that take

place on behalf of the BP AzBU. All contractors directly contracted by any AzBU

Project or Operations Performance Unit, and those directly contracted by UTG Subsea

Team working in the Business Unit must comply with this Safe System of Work.

Whereas the boundary of BP control and accountability is defined by work that takes

place on behalf of BP, it is the intent that through BP influence that all diving and

subsea contractors operating within the Caspian and Black Sea regions shall likewise

comply with these expectations.

Roles and Responsibilities

Operations and Project Groups operating within the AzBU are responsible for the safe

management of diving and subsea projects. They control the diving or subsea

requirement, the worksite and the management control systems. These responsibilities

are met through full compliance with this document and those referenced. Those

responsible for diving in the AzBU must verify that third parties operating within BP’s

sphere of influence accord with the safety management system requirements. Any

deviations from this SSoW or the Dive Safety Management System must be justified

through a risk management process.

Diving Technical Authorities

Within the AzBU, two diving technical authorities are recognized

- one for the

Operations Performance Unit, and another for Azeri Projects Performance Unit. Prior

to commencement of any new diving operation the respective technical authority must

be consulted.

In addition, the AzBU seeks further advice and guidance from recognized technical

authorities within the Upstream Technology Group (UTG Dyce, Aberdeen). Besides

technical competence on subsea operations, UTG also provide independent audit of

compliance with the Diving and Subsea Operations Practice. If required, UTG will

provide preparation, planning and support for diving and subsea emergency response

and investigation of diving related accidents.

Dive Contractors

Dive contractors are responsible to fully understand and comply with the requirements

for development of the safety management system. Other third parties not directly

contracted by the AzBU but working within the BP sphere of influence must also

comply with the SMS requirements.

Management of the Diving and Subsea Operations SsoW

This custodian for this Safe System of Work is the Business Unit central HSE

Department. Regular review, maintenance and management of document changes are

the responsibility of HSE through reliance on technical input from the technical

authorities.

Dive Responsible Personnel and Company Authorized Representatives

Responsibilities for these individuals shall be thoroughly defined in the work scope

that all diving operations comply with the safety management system. In addition, they

must be competent in their ability to provide overall HSE assurance in accordance with

other AzBU standards.

Safety Management Process

The intent of this SSoW is to describe the applicable processes for the management of

diving and subsea operations within the AzBU. Prior to the commencement of any dive

operation the BP Technical Authority shall develop, or shall ensure that the dive

contractor develops a Dive and Subsea Operations Safety Management System

(SMS). The components of the SMS are depicted in the following figure, and shall

include as a minimum the various elements described in this section.

end users and owners of Diving Systems

International SuperLite 17 & MK 21 helmet neck

clamps, DSI Part #505-055, to a potential

problem with the welded stud on the neck clamp

assembly.

Inspect your neck clamp immediately.

This weld should have 1/8" of material (1/8" fillet weld) all around the stud as shown in figure

A. If your clamp has a weld like the one shown in figure B, (no extra material), please return

it to your nearest Authorized DSI Dealer immediately for inspection and replacement, if

necessary.

NOTE: The potential of possible failure of the weld shown in figure B increases when the

user's neck clamp is not properly adjusted.

If you use any neck seal other than the standard DSI neck dams,

YOU MUST RE-ADJUST YOUR NECK CLAMP ASSEMBLY FOR PROPER OPERATION!

Before every dive, your equipment must be completely checked for any damage or wear.

Even normal wear and aging will eventually result in the need to replace parts. Any abnormal

condition of any component requires the removal and replacement of the component. If any

part doesn't look right, don't use it. All metal parts should be inspected for cracks or

corrosion and replaced immediately if this type of damage is found. While some surface rust

or corrosion is to be expected, severe corrosion can lead to the eventual failure of the part.

Important Caution Note

This reference guide is to eliminate confusion as to which neck clamps qualify for Warranty

Replacement. Please check that neck clamps fit these specifications before sending

them to DSI. Any type of marking on the hinge block area does not warrant replacement.

The purpose of this Safety Notice is to alert all end users and owners of Diving

Systems International SuperLite 17 A/B & MK 21 helmet neck clamps, DSI part # 505-

055 to a potential problem with the welded stud on the neck clamp assembly. The

welded stud on some clamps may not have sufficient weld and could pose a Safety

Threat.

Prior to April of 1999, the neck clamp assemblies were not marked in any way. These

assemblies were manufactured to an engineering drawing calling for a minimum

standard of 1/16" inch (.0625) (1.588mm) fillet weld on the stud

(fig A below).

Beginning in April of 1999, neck clamp assemblies are

manufactured with a date of production and identification number

engraved directly onto the part. Every neck clamp is N.D.T.

(nondestructive testing) tested to A.W.S. standard D1.1. These

clamps are welded to a minimum standard of 1/8" inch (.1250)

(3.175mm) fillet weld on the stud (fig A below).

All owners and end users of the SuperLite 17 A/B and US

Navy MK 21 helmets should inspect the welded stud as

follows:

Determine if the clamp has a manufacture date stamp as

illustrated.

If it does, you should check to ensure the stud contains a minimum of 1/8" inch (.1250)

(3.175mm) fillet weld as shown in illustration A. The weld leg length must be no less

than 1/8-inch (.1250) (3.175mm).

If there is no date stamp, you should check to ensure the stud contains a minimum of

1/16" inch (.0625) (1.588mm) fillet weld as shown in illustration A. The weld leg length

must be no less than 1/16" inch (.0625) (1.588mm)

Scope

The contents of this Safe System of Work 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

SSOW.

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

contractors. Neither does it supersede any national and local regulatory

requirements.

This SSOW contributes to compliance with the “HSE expectations” contained in

“getting HSE right”, the ‘Golden Rules of Safety’ and the Control of Work (CoW)

standard that the Hazards associated with BP activities are identified and that the

Risks are assessed and managed.

All guidelines contained shall be regarded as the minimum requirements for BP

owned or managed sites in Azerbaijan and Georgia.

This document applies to the electrical isolation of equipment for work. It shall be

followed at all AzSPU operated sites / installations and is applicable to both onshore

and offshore.

1.3

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.

1.4

Stopping Unsafe Work

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

Control of Work (CoW) Policy and this Energy Isolation - Electrical procedure make it

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

that they consider to be unsafe.

1.5

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

Energy Isolation Golden Rules of Safety

Energy Isolation is one of BP‟s Golden Rules of Safety and states:

Any isolation of energy systems, e.g. mechanical, electrical, process, hydraulic,

pneumatic, gravitational, chemical, radioactive, thermal, or other energy source that

could cause injury, cannot proceed unless:

 The method of isolation and discharge of stored energy are agreed and

executed by a responsible person

 Any stored energy is safely discharged

 A system of locks and tags is utilized at isolation points

 A test is conducted to ensure the isolation is effective

 Isolation effectiveness is periodically monitored

3.12 Competent Person (CP)

An essential requirement for persons undertaking electrical work is that they are

competent, established by virtue of training and or experience. A competent person

is capable of recognising danger and knows when to seek guidance when the work

falls outside their area of competence.

The employing company will certify competency of the employee and will supply BP

with copies of their competence assessment as required. The AzSPU certifies the

competence of its own employees using CMAS.

Self-regulation and Audit

Business Units shall periodically review isolation related activities, including review of

individual isolations and review of overall isolation processes. Such reviews may

also include:

 General compliance with this document and any local procedures

 The assessment of non-compliant isolations and the extent of any approved

deviations

 Registers of competent and authorized persons

Isolating Authority - Training, Competency and Authorisation

The Isolating Authority will be authorized by SM / SC / OIM based on the following

criteria.

The Isolating Authority will be:

 Familiar with the site / installation

 Have Electrical First Aid Training

 Will be EX certified, when working on Hydrocarbon Plants

 Where appropriate, will have HV operational training

Isolation and Planning

7.1

Isolation

The highest quality and security of isolations, which is reasonably practicable in the

prevailing circumstances, shall always be used. This document sets out the

minimum recommended isolation standard to be used in the Azerbaijan Strategic

performance Unit.

Any isolation, which does not meet the Minimum Recommended Isolation Standard

as defined in section 7.5, including the application of the Mandatory Safeguards,

must be assessed using the Level 2 Risk Assessment Process before the isolation is

approved. Should any non-compliant isolation have to be repeatedly justified by risk

assessment, consideration shall be given to a permanently engineered solution.

All key participants in the implementation of the BP Isolations Policy shall be trained

and assessed as competent to the appropriate level in the Electrical Isolation

Standard.

An audit programme shall be established by the SM / SC / OIM at each site to ensure

that regular checks are made on isolations to provide assurance that the isolations

policy and standards are being applied and that lessons learned are communicated

effectively.

7.2

Isolation Planning

Isolation of any piece of equipment shall be planned to minimize risk to personnel,

property and production. To achieve this, the following information will be required:

 A clear description of the work, ensuring that if the activity includes electrical

work that this is clearly identified

 A clear description of the equipment which needs to be isolated, this will

include the Plant Tag Number and the Plant Tag Description

 A drawing identifying the isolation, earth and disconnection points where this is

not obvious

 Tag references of all the switching and isolation points

 Locks and Labels for securing the isolation points

 Test equipment for proving effectiveness of the isolation

 Switching program detailing the sequence of switching required to achieve the

isolation where the equipment is fed from more than one source or at the

REP‟s discretion.

7.3

Switching Programmes

Where main distribution equipment is to be switched it is essential that the equipment

be switched in the correct sequence. To achieve this, a switching programme will be

required, detailing the switching sequence. This will be accompanied by a marked

up single line drawing. An HV switching programme will be prepared by an SAEP

and checked by the REP. Where the REP is alone on site, the site electrical

technical authority will check the switching program. Technical advice will be sought

as required. See Appendix C for a blank Switching Programme. The Switching

Programme does not replace an ICC.

7.4

Isolation Methods

The highest quality of isolation, which is reasonably practicable, shall be applied to

every individual isolation point. The methods of isolation normally available are

detailed below; listed in descending order of security and effectiveness. The key to

all of these isolations is the positive identification of the equipment to be isolated, to

this end all equipment and isolation points on a site will be uniquely identified and

clearly labelled, a secondary check could be to use the cable numbers which connect

the isolator to the equipment. If there is any doubt about the correct identification of

the equipment to be isolated and the isolation point then the work should be

suspended and clarification sought.

(a)

Isolate Circuit, Prove Dead, Disconnect, Lock, Label and Earth

This is a positive isolation of the main phase conductors with an isolator and

disconnection of the main phase and neutral conductors by removal of fuses, links or

withdrawal of a circuit breaker or some other means of disconnection. The circuit is

proven dead to ensure that the circuit is discharged and is earthed to prevent

recharging. Locks and labels are applied to all points of isolation and earthing

Note: When the isolation requires switching of main distribution equipment, a

Switching Program is also required.

(b)

Isolate Circuit, Prove Dead, Disconnect, Lock and Label

This is a positive isolation of the main phase conductors with an isolator and

disconnection of the main phase and neutral conductors by removal of fuses, links or

withdrawal of a circuit breaker or some other means of disconnection. The circuit is

proven dead to ensure that the circuit is discharged. Locks and labels are applied to

all points of isolation.

Note: Where the isolation switch meets the minimum standard for disconnection, as

defined in IEC

60947, and it includes all phases and neutral then no further

disconnection is necessary if the risk of physical disconnection outweighs the

advantage. However, this is a minimum standard and it is expected that if fuses or

links are part of the circuit that they will be removed.

(c)

Isolate, Lock and Label (not suitable for electrical work)

This is a positive isolation of the main phase conductors with an isolator; the isolator

type will be of such construction that it breaks the main phase conductors when

open. Locks and labels are applied to all points of isolation.

Note: Isolation by auxiliary control circuits only is not acceptable for isolation

purposes.

(d)

Prove Dead, Disconnect, Label

This is a positive isolation typically used for isolating instruments where there is no

lockable isolator. It is required that the circuit cable cores are disconnected from the

terminal rail and terminated into a temporary terminal block with isolation labelling at

the disconnected cores.

General Note:

When completing the isolation confirmation certificate for reasons of clarity the check

block should be completed with YES when:

Isolated

When the isolation point has been isolated to the

approved standard as defined in this document

Fuse Removed

When at the isolation point Fuses or Links have

been removed

Disconnected

When at the isolation point a cable is removed ( the

isolation point tag reference will be the termination

point of the cable and the cable number)

Earths

When any earth is applied

( the isolation point tag

reference will be the earth application point)

Proved Dead

When a point in the circuit has been positively

proven dead as defined in this document ( the

isolation point tag reference will be the prove dead

test point)

Risk Assessment of Non-compliant Isolations

In the event that the Minimum Recommended Isolation Standard cannot be

achieved, a Risk Assessment shall be carried out in accordance with SSOW

guidelines

The assessment team, including the REP shall specify appropriate safeguards, which

may replace or be in addition to those listed in Table 1. The team shall be satisfied

that these safeguards shall reduce the risks to an acceptable level before the task

requiring isolation is permitted to proceed.

The SM / SC / OIM must authorize all level 2 risk assessments prior to any work

proceeding.

7.7

Live Working

Live working is defined as work on or in close proximity to live conductors; this

includes testing.

All conductors will be assumed live unless proven dead. (See section 8.9)

Live work will not be a normal activity and will not be carried out unless there is no

other reasonably practicable method available. Where it is not possible to avoid live

work, an appropriate level of risk assessment shall be carried out before work

commences.

Is the live working justified? Consider:

 If the work could be done when equipment is isolated (an example of work

which must be done live would be work on battery systems)

 If isolating the equipment introduces other greater safety risks

 When identifying the risks consider:

 Voltage level

 Fault level of the equipment and the arc energy if a fault develops while

working

 Working environment (wet, dusty, noisy, vibration, at height etc)

 What exposed voltage levels will be adjacent to the worksite

 What could go wrong

Can adequate precautions be taken to reduce risk to an acceptable level? Some

precautions, which should be considered:

 Competent people with training and experience

 Insulated tools and test equipment

 Accompanied work - Accompanying person to be First Aid Trained and it

should be clear what is expected of the accompanying person to ensure that

they are competent to accomplish this expectation

 Insulated barriers, mats, grab hooks

 Work site control (e.g. cordoning off area, limiting access)

 Additional and / or specialist personal protective equipment

 Reference to any specific safety rules or guidance

See Appendix F for a flowchart covering the Control of Electrical Work.

Isolations for Work Near Live Conductor

Frequently, work inside of complex control equipment means that although the circuit

to be worked on is isolated, there may be other circuits that are still energised. It is a

requirement that the risk from these adjacent conductors is assessed and

appropriate precautions taken to reduce the risk.

See Appendix B for an adjacent working assessment form.

Isolation Implementation and Control

8.1

Security

Any isolation must effectively disconnect the worksite from all sources of energy.

Locks must be used to prevent unauthorized de-isolation; to this end unique locking

devices must be used. Keys to any locks used for isolation purposes must be

effectively controlled via the Area Authority and the Permit to Work

- Isolation

Confirmation Certificate (ICC). Only when the ICC allows should the Area Authority

make the key available to remove a lock.

The locks should be a high security type, which are tamper proof. See appendix D.

Procedure for Energy Isolation - Electrical

Page 15 of 32

8.2

Isolation Labelling

All isolation points shall be clearly identified, tagged and recorded on the ICC.

Where not obvious, a drawing should be attached to the ICC showing the location of

each isolation and earth point (where applied).

At the isolation point there should be a Yellow Isolation Label with the following

clearly identified:

 ICC number

 The Tag number of the isolation point

 Reason for isolation

 Isolation Authority name and signature

 Date

At the Earth point there should be a Green Earth Label with the following clearly

identified:

 ICC number

 The Tag number of the isolation point

 Reason for isolation

 Isolation Authority name and signature

 Date

Adjacent live circuits will be identified with a Red Danger notice, e.g. live bus bar

shutters when work is to be carried on the circuit.

See Appendix G for labels

8.3

Positive Identification of Equipment

To allow effective isolation, equipment must be clearly labelled with unique tag

numbers. If equipment is not tagged then another method of positive identification of

equipment must be used, e.g. use of the cable number and cable schedule and

interconnection drawings. These provide a unique number, which should be located

at each end of the cable. If there is any doubt about the correct identification of the

equipment to be isolated and the isolation point, then the work should be suspended

and clarification sought.

8.4

Control of Isolations

The ICC, cross-referenced to all relevant work permits, shall be the principal means

of control once isolations are in place. The ICC performs the following functions:

 Identifies the plant concerned and the reasons for isolations

 Authorises isolation by disciplines

 Records the complete list of isolation points

 Records „prove dead‟ operations

 Records the position of any earths applied

 Records locking points and lock numbers

 Records where isolation labels have been applied

 Confirms that the isolation has been effected

 Authorises any temporary de-isolations and isolations necessary for testing

(sanction for test)

 Authorises and records de-isolations on completion of the task

 The Area Authority must effectively control all keys for locks used for isolation.

8.5

Operational Locks

Operational Locks will be used as required on switchgear to ensure that normal

operating standards are maintained. These locks will be kept in the switch rooms in

lock cabinets where only appropriately authorised competent personnel will have

access.

An example of this would be manual close buttons on switchgear, which will normally

be locked for operational purposes and unlocked for maintenance or for transformer

offload tap changers.

Appendix: D shows an example of an operational locking system, which could be

used for the control of locks.

8.6

Boundary Isolations

Where an area of plant is isolated such that several activities (typically construction

work) can safely take place within this common set of strategically placed isolation

points then this can be termed as a „Boundary Isolation‟. It must be clearly identified

that the isolation is appropriate for all the individual tasks to be carried out within the

Boundary Isolation and all individual Work Permits are cross-referenced to this

Boundary Isolation.

If any of the proposed tasks require a level of isolation or implementation of control

measures greater than that covered by the Boundary then a separate Isolation

Confirmation Certificate should be raised for this task.

Thorough planning and preparation is essential when planning Boundary Isolation. A

team including the Area Authority and Isolating Authority and any additional technical

support required should be set up away from the work place to properly review and

agree the scope of the Boundary Isolation and the tasks to be carried out.

Once work is in progress and subsequent Work Permits are applied for within the

recognised framework of the Boundary Isolation, they can be added providing it is

clearly established that the existing isolation is appropriate to the task. However, this

should be avoided if possible and it is preferable to identify all activities when the

Boundary isolation is being planned.

Boundary Isolations shall not be removed until all applicable Work Permits have been

cancelled.

If, for any reason, work on a particular piece of plant within the Boundary needs to be

suspended

(e.g. whilst awaiting spares) then a separate isolation shall be

implemented and an ICC raised before the Boundary Isolation can be cancelled and

confirmation that the installation can be energised safely.

Where the de-isolation of the Boundary Isolation is proposed, the Area Authority shall

ensure that all associated Work Permits have been cancelled. He/she should also

ensure that equipment within the boundary is in safe condition.

8.7

Long-Term Isolations

Long-term Isolations (LTI) are defined as those that no longer have work performed

against them. Each site should maintain a detailed register of long-term isolations

with a reason why they are in place.

Long-term isolations shall be subject to two levels of review:

 A weekly review of the register to check the status of the isolations in place

 A quarterly review to physically check all the isolation points to confirm their

security and integrity and that the keys to all locks are being adequately

controlled

 If the LTI is in place for more than 1 year, review the requirement for LTI.

Consider if something else could be done (i.e. decommission circuit)

Before any work is performed against a long-term isolation a full integrity check of all

isolation points is required and the point of work must be proven dead.

Before an electrical LTI is removed a physical check of the equipment to be

energized will be made to ensure that the equipment is safe to energize.

8.8

Personal Isolations

Personal isolations are intended for short-duration tasks of relatively low risk. For

example, when work is required on a single motor feeder circuit or other such tasks

where the completion of an ICC is considered to add no significant value in terms of

risk reduction. The use of personnel isolation may only be authorized by the Area

Authority on the permit to work. The rules for approval of a personal isolation are as

follows:

 One person within one shift performs the task and isolation; the person may

receive assistance from others but he/she shall be present at all times when

work is in progress

 Before approval, the Area Authority must be satisfied with the competence of

the Performing Authority and check that they have sufficient authorisation to

both carry out the isolation and execute the work. Personal isolations shall

only be carried out by those deemed to be a competent Isolating Authority

 The same isolating standards apply to personal isolations other than the

completion of the ICC

 The isolation points shall be labelled with an isolation label (which includes the

date, the name of the person isolating and the task information) and locked

(the Performing Authority must keep effective control of keys to isolation locks)

 If the worksite is left unattended, the plant shall be left safe, with all covers or

barriers in place

 The personal isolation is authorised on the work permit

An ICC shall be raised if any of these conditions cannot be met or conditions change

during the work activity.

Personal isolations are not allowed on the following:

8.9

Testing Isolation Integrity - Proving Dead

All electrical conductors shall be considered to be live until positively proven dead

using an approved live line tester suitable for the voltage to be tested; this tester will

be proved both before and after use. The conductor will be proven dead between

circuit and earth. Where there is a neutral or the system is unearthed the conductors

will also be proven dead between all of the circuit conductors. It is a requirement

under the BP Golden Rule of Energy Isolation that energy has been discharged and

that testing has proved the isolation.

The Performing Authority will be required to witness this test or prove dead

themselves before commencing work on any conductor.

It is essential that after testing with an applied voltage, a conductor be adequately

discharged to earth using approved discharging equipment. Once discharged, the

conductor is again proven dead.

Proving Dead is considered to be live working and therefore each location must

assess the risks of this activity based on sited conditions and produce a standalone

risk assessment, which covers this activity. The understanding of these precautions

will form part of the authorisation process for the site.

8.10 Monitoring Isolation Integrity

Locks and effective control of their keys maintain the integrity of electrical isolation.

An isolation lock may not be removed unless written permission is given on its ICC. A

lock may not be removed by any other means than the key. If for any reason the key

is not available, the Area Authority, Responsible Electrical Person, Isolation Authority

and Performing Authority must apply in writing to the OIM / Site Manager / Site

Controller for permission to remove the lock.

Where possible, a multi-hasp device will be used to allow for more that one padlock

at each isolation point.

If the integrity of the isolation requires the use of barriers or shields then their

condition will be checked before the start of any work activity.

De-isolation of Plant

Before plant is de-isolated the Area Authority shall ensure that all work is complete,

all permits are cancelled, all covers and safety barriers have been replaced, the plant

has been tested and inspected and any relevant certification is completed. When the

Area Authority is satisfied and has checked that there are no other permits cross

referenced to the isolation, he will instruct the Isolation Authority to de-isolate the

plant.

Appendix D: Operational Locking System

Locking system for electrical equipment after energization covering operations

and isolation control

Operational locks

Each switchboard will have a locking suite of unique locks for each locking point on

the switchgear these will be housed in a lock cabinet within the switch room. Access

to the locking suite will be controlled to suitably authorized persons.

The locks should be a high security type, which are tamper proof. (an example of such a

lock is the ABLOY high security padlocks). There should only be one key that fits a lock

in the isolation system (any spares or masters are to be removed and controlled by the

site manager who should only issue these keys after the REP has made a formal request

in writing)

The keys to these locks will be kept with the locking suite for the switchboard.

Isolation Locking

When the Area Authority requires an isolation to be locked off, a lock and key will be

taken from the switchboard-locking suite that the isolation is required for. Where

possible a multi-hasp will be used and the lock and label will be applied.

Once the locks are in place the keys will be returned with the ICC to the Area

Authority who will control the keys until a de-isolation or a sanction to test has been

approved.
