4.4

AUTHORISED GAS TESTERS (AGT’S)

An Authorised Gas Tester is a person who has been trained and certified. Training and

certification covers 3 levels, AGT 1, 2 and 3, with Level 1 being the highest level. Only AGT Level

1 trained personnel have the required level of training to test confined spaces.

Level 1 AGT’s are competent to carry out gas testing on all activities including Confined Space

Entry (CSE). For confined space work the Level 1 AGT must retest the atmosphere at the start of

each shift, or when the work has been suspended for an extended period within the shift.

The AGT1 shall:

 Prove the safe atmosphere (i.e. free of toxic and flammable gases) in the confined space

using correctly calibrated gas testing equipment in his charge with an understanding of the

limitations of the equipment

 Prove Oxygen Levels within levels required

 Enter the readings obtained while testing the atmosphere in the Confined Space onto the

Confined Space Entry Permit

 If the atmosphere is within the acceptable limits for entry, sign off the appropriate section on

the WCC in ISSOW system

 Where the gas concentrations are outside the acceptable limits the AGT1 should NOT sign

the permit, but discuss with the AA and PA measures to further purge the space

 Observe and record any sludge or scale in the Confined Space and record it on the

Confined Space Permit ensuring that the findings are clear and easy to read.

Level 2 AGT’s are qualified to carry out gas tests in support of all activities excluding Confined

Space Entry & carry out continuous monitoring during ongoing work.

Level 3 AGT’s are individuals, usually the PA, who are approved by the Site Controller as having

undergone practical instruction by a Level 1 or 2 AGT on the use and interpretation of the results

from both portable and personal gas monitors. The AGT3 has no authority to record gas test

results on PTW; their responsibility is only for continuous monitoring.

 Be briefed on all aspects of the proposed entry activities in CSE (ref. CoW Training Policy

AZSPU-HSSE-DOC-00088-2)

 Follow established safety standards and practices

 Participate in a Toolbox Talk

 Understand the conditions required by the Confined Space Entry Permit and the

associated Permit to Work

 Know and recognise the hazards that may be faced during entry including signs or

 Alert the attendant if an unsafe condition exists or when symptoms of exposure appear

 Come out from the confined space as soon as possible when:

o Ordered by the attendant

o The entrant recognises the warning signs or symptoms of exposure

o An unsafe condition exists.

4.6

CONFINED SPACE ATTENDANT

The Confined Space Attendant has a vital function to perform. Under no circumstance may the

Confined Space Attendant enter the confined space or leave his post whilst there are personnel

inside. The Area Authority must ensure that the Confined Space Attendant understands his

duties and is competent to perform them.

The attendant must be trained, assessed and authorised (ref. CoW Training Policy AZSPU-

HSSE-DOC-00088-2) to carry out his/her duties and must attend the toolbox talk before the start

of work. He/she must remain outside the confined space, in a safe atmosphere and safe

physical position, at all times during a confined entry operation and perform the assigned duties

under this procedure. He/she must also:

 Maintain an accurate count of all persons in the space by:

o Using a personnel log-in/log-out system on which the name, entry and exit times for all

personnel entering or leaving the confined space shall be recorded

o Marking airlines and / or safety lines so that each individual inside the tank is clearly

identified in the event of a problem

 Be aware of the hazards that may be faced during entry, including the mode, signs or

symptoms, and consequences of any exposure

 Monitor conditions and activities inside and outside the space to determine if it is safe for

entrants

 Remain outside the confined space during entry operations until relieved by another

Attendant

 Keep entrants under effective surveillance and maintain effective and continuous

communication with them during entry by one or more of the following methods:

o Line-of-sight (not always possible)

o Voice contact (allowing for distance and ambient noise)

o Radio with agreed periodic contact

o Pre-arranged signals on air-klaxons, whistles etc

o Pre-arranged lifeline signals

o Distress signal unit

 Order authorised entrants to evacuate the confined space immediately if:

o A condition is observed that is not allowed

o Behavioural effects of hazard exposure are detected

o A situation occurs outside the confined space that could endanger the entrants

o An uncontrolled hazard is detected inside the confined space

o The attendant must leave the work station

 Ensure unauthorised persons are not allowed to approach or enter a confined space while

entry is underway

 Be equipped with a device (e.g. radio, telephone) to summon assistance rapidly if entrants

get into trouble.

Notes:

Rescue and resuscitation equipment shall be near to the worksite and personnel trained in its

use will be readily available and aware of the entry.

Consideration must be given to having the rescue team attend the pre-job briefing to ensure

familiarity with the proposed work.

Ensure that an adequate supply of respirable air is maintained whilst Entrants are inside the

confined space. CSE Entry Standby Man/Attendant Duties Checklist was attached to the

procedure under Appendix C

5 CONFINED SPACE ACTIVITY

5.1

EXAMPLES OF CONFINED SPACES

A Confined Space may be any place included in the following example list, in which by virtue of

its enclosed nature, there arises a reasonable foreseeable specified risk. The list below is not a

complete listing; therefore do not assume if not on the list that it is not a Confined Space.

Some confined spaces are easy to identify and include:

 Storage tanks

 Silos

 Process vessels and exchangers

 Road and rail tankers

 Enclosed drains and sewers

 Sumps

Other confined spaces can be less obvious but just as dangerous. Examples include:

 Ductwork

 Void spaces

 Trenches & excavations

 Vessel skirts

 Rooms with limited ventilation

 Temporary tented areas (unless ventilation is specifically designed for worst-case leakage

inside the area).

Procedure for Confined Space Entry

Page 13 of 34

All excavations and trenches deeper than 1.2 metres in “hazardous areas” as defined by the site

/ installation are classified as confined spaces.

In “non hazardous areas” where there are no significant hazards identified prior to entry, the

following criteria must be established before determining the requirement for a “Confined Space

Entry permit”:

 No risk of atmospeheric hazards either from surrounding area or from the task being

performed.

 The excavation does not require any form of isolation prior to entry.

 No risk of engulfment from ingress of solids or liquids.

 No risk from excessive heat.

 Safe means of access and egress for work party

 Safe means of aceess and egress for rescue purposes

 Excavations benched or shored to reduce risk of collapse (Ref. AZSPU-HSSE-DOC-

00050-2 - Procedure for Excavation.)

 Continuous monitoring of O2, LEL and other toxic gasses are carried out inside the

excavation / trench

The excavation / trench may be classified as “not a confined space” if all the above criteria can

be established and a Level 2 Risk Assessment is conducted.

Note: A Permit to Work and Level 2 Risk Assessment are mandatory for “all work” in

excavations and trenches deeper than 1.2m.

5.3

HAZARDS ASSOCIATED WITH CONFINED SPACES

Dangerous concentrations of gases and vapours can arise from sources inside or outside

a confined space. These include:

 Toxic substances in hazardous concentrations, e.g., hydrogen sulphide (H₂S), benzene

and hydrocarbon gases that remains from the process or enters from adjoining plant

because it has not been effectively isolated

 Flammable gases, vapours and liquids with potential for fire or explosion

 Gas or vapour emitted from scale or sludge, particularly resulting from mechanical

disturbance during access or cleaning or due to the heat from welding operations

 Gas, vapour or fumes produced by operations being carried out in the confined space

such as welding and cutting, brush and spray painting and the use of adhesives and

solvents

 Exhaust gases drawn into the confined space from prime movers or heating equipment

Dangerous situations can arise from sources inside or outside a confined space. These

include:

 Failure to positively isolate the confined space

 Mechanical equipment in the space

 The ingress of steam, hot water or other liquids which may cause scalding or drowning

 Communication difficulties

 Poor access and egress restricting movement for normal work and escape

 Poor access and egress for rescue

 Slippery surfaces

 Sources of ionising radiation (e.g. level gauges, sludge and LSA scale or NORM)

 Any confined space that might normally contain naturally occurring radioactive material

shall be checked by a certified Radiological Protection Supervisor and shall be subject to

the requirements of procedure AZSPU-HSSE-DOC-00058-2 - Management of Radioactive

Materials and Radiation Generators

 Where vessels are fitted with Nucleonic Gauges for measuring levels or product density,

the source must be disarmed or retracted, the source must be made safe in accordance

with procedure AZSPU-HSSE-DOC-00058-2 - Management of Radioactive Materials and

Radiation Generators

 Vessel boots and sumps full of liquid which could be fallen into

 Pyrophoric scale formed in systems

 Systems which may contain H₂S

 Excessive noise

 Inadequate visibility

 Excessive temperature in the confined space (causing heat stress to personnel)

 Possible ingress of fumes from drain systems etc

 Possible collapse of excavations due to inadequate shoring.

Dangerous situations can arise from oxygen enriched or deficient atmospheres

The special dangers of working in oxygen-enriched atmospheres cannot be over emphasised.

Oxygen enrichment may occur by leakage of oxygen supplies or by build-up of oxygen during

oxygen-rich flame cutting processes.

Enrichment of only a few percent will make materials that will normally only burn slowly or with

difficulty, burn fiercely with catastrophic results for the occupants of the confined space.

Every precaution shall be taken to avoid oxygen enrichment. In particular:

 Oxygen cylinders shall be kept outside the confined space where practicable.

 Oxygen supplies shall be isolated outside the space during work breaks

 Hoses supplying oxygen shall be removed from the space during work breaks.

 Oxygen shall never be used to 'sweeten' the atmosphere of a confined space.

 The space shall be adequately ventilated at all times

There is also a danger of oxygen deficiency due to combustion processes, purging with inert gas,

inert gas welding (MIG/TIG) or oxidation processes (e.g. rusting) occurring in steel vessels left

completely closed for some time.

Other potential hazards include:

 Electric shock or ignition of flammable gases from portable lights, tools, or associated

electrical equipment.

 Possibility of static electricity build-up due to a lack of proper bonding and grounding

CONFINED SPACE PERSONAL PROTECTIVE EQUIPMENT (PPE)

5.4.1 Personal protection

Appropriate personal protection as identified by Level 2 Risk Assessment, e.g., head, foot, hand, eye,

ear, face, body and respiratory protection, must be worn when entering an Entry Permit Controlled

Confined Space.

Where required by the Risk Assessment a life-line attached to a full body harness should be used by

all entrants during entry into a confined space.

5.4.2 Respiratory Protection

Dependent upon the type and concentration of contaminants, respiratory protection may range from a

simple cartridge respirator to air-supplied breathing apparatus. When the level of airborne

contaminants is beyond the filtration capability of a respirator, as defined by the vendor, or where

there is an oxygen deficiency, then breathing apparatus must be used.

In order to ensure that grit, particles and other contaminants could not enter a supplied air

respirator/breathing air system when air supply hoses are disconnected and/or reconnected, the

responsible people shall carry out this work away from the contaminated environment.

5.4.3 Breathing Air Standards

The need to ensure a continued provision of good quality breathing air relies on regular changing of

air filters and maintenance of dryers, supported by periodical analysis of the breathing air supply.

Under no circumstances shall Instrument or Plant Air be used for breathing duty.

Note: Breathing air shall conform to BS EN 529: 2005 - Respiratory protective devices.

Recommendations for Selection, Use, Care and Maintenance Guidance Document.

BS EN 12021:1999 - Respiratory protective devices. Compressed air for breathing

apparatus.

5.4.4 Air Line Masks

Air line breathing apparatus shall be approved and conform to BS EN 14593-1:2005, BS EN

14593-2:2005 and BS EN 14594:2005. The full face mask enables the wearer to work for long

periods in harmful atmospheres, whilst breathing air is supplied by either portable air compressors

fitted with reservoir air tanks, or a battery of compressed air bottles.

Connections to the air line mask hose are made via instantaneous bayonet spring couplings. These

couplings and air hoses must be approved by manufacturer, kept in good condition and must not be

used for any purpose other than supplying air to breathing apparatus.

Couplings integrity shall be checked prior to entering a confined space wearing air line masks or

breathing apparatus.

5.4.5 Using Portable Air Compressors

Where no compressed air bottle supply is available, portable air compressors having a reservoir air

tank may be used. In such cases:

 The compressor air intake(s) must be upwind of any known source of contamination to ensure

clear air being fed to the user (a wind sock indicating wind direction should be flown in the

vicinity of the intake to the compressor)

 The system of air supply employed should incorporate a receiver of sufficient capacity to enable

persons to escape from an irrespirable atmosphere in the event of a failure of the prime mover

supplying the air

 The air must be passed through suitable filters to remove excess moisture and oil mist.

Note: To ensure that an adequate supply of air is available and being received by the wearers, a

suitably competent person must be appointed who is responsible for checking the pressure in

the air receiver, and for ensuring the filters are functioning properly.

5.4.6 Self Contained Compressed Air Breathing Apparatus (SCCABA)

SCCABA shall conform to BS EN 137:2006 "Self Contained Compressed Breathing Apparatus".

These sets are provided where a portable supply of air is required for a short period of time.

The air for this apparatus is supplied under pressure either from compressed air cylinders carried by

the wearer or from trolley sets.

All persons required to use breathing apparatus must receive initial training and refresher training at

intervals not exceeding one year. The training shall be recorded.

5.4.7 Escape Breathing Apparatus

Any person entering a Confined Space using an airline Breathing Apparatus shall be provided with an

Escape Breathing Apparatus set with a bottle capable of supplying an emergency air supply for

approximately 10 minutes. This set shall also conform to BS EN 137:2006 "Self Contained

Compressed Breathing Apparatus".

5.5

MONITORING AND AUDITING

CSE activities shall be managed and monitored at defined intervals by the responsible people, such

as Area and Performing Authorities. Area Authorities and Performing Authorities shall maintain regular

communication with those performing CSE activities.

Monitoring of CSE work shall ensure that:

 The activities are carried out safely and the conditions of the permit are not compromised or

changed

 A responsible person is assigned and attends the CSE worksite at defined intervals, the

frequency of which is determined by the Risk Assessment, to check if permit conditions are still

complied with.

Hand-over between work parties involved in CSE activities at shift change before starting the work

shall include the status of continuing work, a re-appraisal of site conditions and the appropriate control

measures.

The responsible person charged with monitoring the ongoing work shall:

 Identify when the site conditions have changed

 Assess when the original permit no longer accurately covers the task, stop the job if necessary

and request a re-assessment

 Have the required competence to recognise when site conditions no longer comply with the

permit requirements

 Investigate any indication from the workforce that the work may be unsafe.

An assigned person shall ensure that the status of permits (including a register of associated inhibits/

room, the site office, or electronically). Copies of all permits and associated certificates currently in

force shall be held at a designated location.

Each Operating Area shall undertake regular recorded internal audits of the operation of Confined

Space Entry to check the compliance with the requirements of COW GDP and this procedure. The

auditing process including frequency, checklist, register, actions, tracking and close out may be a part

of the audit program of the CoW System at each site.

These audits should include the following requirements:

 Audit results shall be recorded, analysed and used to improve the management and quality of

the Confined Space Entry Process as a part of CoW.

 The scope of any CSE (CoW) audit shall include individual permits and any associated risk

assessments. In addition, it shall cover the CSE (CoW) documentation processes and

procedures as well as their correct use and application.

Internal and external lessons learned that impact the CSE activities shall be captured, incorporated

and shared.

5.6

COMPETENCY AND TRAINING REQUIREMENTS

Persons involved in the Confined Space Entry process as a part of COW shall be trained (attendants)

or briefed (other participants) and shall meet the competency requirements for their assigned CoW

roles.

All Competency and Training requirements are to be in compliance with the terms and conditions of

CoW Training Policy AZSPU-HSSE-DOC-00088-2.

The competency levels of persons involved in CSE operations shall be checked at a defined

frequency. Refer to AzRPU Authorisation Procedure AZSPU-HSSE-DOC-00012-2 and AzRPU COW

A register will be held on site of all personnel deemed competent for all the roles associated with

Confined Space Entry, and will be managed by the Site Manager / Site Controller / Offshore

Installation Manager.

5.7

PLANNING AND PROCEDURES

All alternatives to entry must be considered before starting to plan for Confined Space Entry.

Prior to entry into a confined space, all affected plant and equipment shall be positively isolated,

emptied, cleaned and gas freed as necessary.

A Confined Space Entry Permit form (See Doc. No: AZSPU-HSSE-DOC-00060-2) shall be issued to

allow the Gas Tester (Level 1) to test the atmosphere in the Confined Space. He will sign the permit

after the test to indicate the atmosphere is safe for the work to be done. The Confined Space Entry

Permit is then attached to the Permit to Work.

Positive isolation (See Doc. No: AZSPU-HSSE-DOC-00049-2), Energy Isolation - Process must be

effected on all live process, utility and service lines and electrical/control equipment for any task

requiring entry to a vessel or confined space. Spool removal is preferred, although spade isolation

may be used where it is not reasonably practicable to remove pipe work sections. It should be noted

that in some cases it may not be reasonably practicable to comply with this requirement when making

entry to mud tanks, pump pits, ballast tanks, or other utility systems. Here, a Level 2 Isolation Risk

Assessment (IRA in ICC which is in ISSOW)) must be undertaken and approval obtained from the

Site Manager, Site Controller or Offshore Installation Manager before entry can be permitted under

work control.

Vessel nozzles should normally be left open to assist with free ventilation. Air movers or ducted fans

may also be used to create a flow of clean air through the vessel. If there is any likelihood of fumes,

water or other contaminant entering the vessel from sources other than the isolated pipe work while

persons are inside, the need to blank off any affected nozzles must be considered. Blanks used for

this purpose do not need to be pressure-rated. However non-pressure rated blanks must be clearly

identified by a tag, painted circumference or other marking. In the case of tanks with 'swan necks',

mechanical plugs may be an option, to prevent ingress of fumes, etc.

The „man-way‟ doors on a vessel being prepared for entry, must be removed last, and reinstalled first

to reduce the risk of unauthorised entry.

Open manholes shall be protected from unauthorised entry (physical barrier/warning sign).

All equipment, particularly electrical isolation points, requires clear unambiguous labelling. Labels and

signage are protective barriers and therefore, should be checked periodically.

5.7.1 Planning process

Planning and scheduling of CSE activities shall identify individual tasks and their interaction.

A documented work planning process of CSE shall be in place and take into account all necessary

resources and time required to safely fulfil all stages of control of work process. It includes hazard

identification, risk assessment, scheduling and equipment preparation. Resources involve the

competent personnel, including subject matter experts, and correct equipment necessary to carry out

CSE work.

Risk of simultaneous operations shall be identified and measures taken to ensure the compatibility of

different activities.

The planning process shall identify dependent and linked activities, including those associated with

planned maintenance. Such activities, if necessary, shall be coordinated and prioritised to allow safe,

efficient and timely implementation of SCE activities.

Planning for confined space entry shall include the following:

 Level 2 Risk Assessment (mandatory) for initial gas test and actual work to be performed

 Positive Isolation to ensure no process or utility fluids or gases may enter during the entry

 Entry Permit preparation to enable Gas Tester to enter the vessel

 Prior to any entry into a confined space, the atmosphere shall be tested to determine the

precautions necessary, and an Entry Permit issued.

 Throughout the period of entry into confined spaces, the atmosphere in the space must be

strictly controlled to prevent persons being exposed to risks associated with toxic and/or

flammable fumes and vapours in the atmosphere, and with atmospheres that may be deficient

(or enriched) in oxygen and extraction / forced ventilation to be provided where required

 Procedures for control of work including procedures for any non-compliance with normal

standards based on the Level 2 Risk Assessment

 Notification of AAA where appropriate

 The resources available to deal with any potential emergency that may arise should limit the

number of personnel entering a confined space.

 Emergency response arrangements:

o Access and egress arrangements should take into consideration the possibility that a

casualty may need to be evacuated in an emergency. It would require a winch to vertically

hoist an average person from a space below. Wearing a harness and lifeline shall only be

considered practicable if the nature of the confined space is such that the attendant could

hoist or drag out the person from the space if the latter were immobilised, and if the rope

would not impede an unassisted exit. Wearing only the harness should also be considered -

a rescuer could attach the lifeline to effect evacuation of the person

o Procedures for entering confined spaces with and without Breathing Apparatus (BA) are

described in Paragraphs 5.15 and 5.16.

5.7.2 Confined Space Planning Flow-Sheet

A schematic diagram to show the sequence of planning for Confined Space Entry is shown in

Appendix A.

5.8

HAZARD IDENTIFICATION AND LEVEL 2 RISK ASSESSMENT (L2RA)

CSE tasks shall not be conducted without being risk assessed.

Level 2 Risk Assessments shall be prepared to establish whether the proposed confined space entry

and the work to be done can be performed safely.

The main hazards associated with entering and working in confined spaces, are listed in Section 5.3

as a checklist for the Risk Assessment.

At least one representative of each workforce team shall participate in Level 2 Risk Assessment prior

to start of Confined Space Entry activities. The outcomes of the Risk Assessment shall be recorded,

communicated to the workforce involved in CSE activities and signed by them.

Worksite shall be inspected by responsible person(s) prior to commencement of Risk Assessment.

Equipment to be used during CSE activities shall be fit for the purpose through inspection and/or

review of certification.

In order to reduce the risk of accident during CSE activities the following hierarchy of control should

be used - Elimination > Substitution > Control > Mitigation.

Based on the outcomes of the Risk Assessment, Emergency Rescue plans (see paragraph 5.21 and

example plan in Appendix B of this procedure) shall be developed and be in place prior to

commencement of CSE activities. Such plans shall be communicated to the workforce to make them

fully aware of the hazards, risks and control measures of working in the confined space environment.

PPE identified as necessary for a safe implementation of CSE tasks (including contractor equipment)

shall be checked by an authorised person at defined intervals to ensure that it is fit for purpose and

within date for testing and re-certification.

5.9

GAS TESTING

Only authorised persons who have been fully trained and certified in gas testing for confined space

entry purposes, i.e. Authorised Gas Tester Level 1 (AGT1), shall carry out gas testing for entry,

The AGT1 shall request an Entry Permit from the Area Authority to confirm that the confined space is

isolated and, if required, to authorise entry for the AGT1. Any special operational conditions inside or

outside the space will be conveyed to the AGT1 on the permit.

Where practicable, the gas test shall be carried out from outside the confined space (e.g. using

extension probes). In some circumstances it may not be possible to sample a representative portion

of the space from the entrance, taking into account ventilation arrangements and the possibility of

heavier than air gas remaining in low areas. In this event, the AGT1 may have to enter the space in

order to complete his tests.

The conditions for the entry of the AGT1 shall include:

 The AGT1 shall not enter if the conditions at the entrance are outside the criteria for entry with

BA (refer to Table 1).

 If an entry is required, then AGTL1 can enter the CS only when CSEA is in place.

 A Confined Space Attendant (refer to Paragraph 4.6) shall be stationed at the entrance so that

he is able to see the AGT1 and equipped to raise the alarm if the AGT1 should get into trouble

and also to warn the AGT1 of an external emergency.

 The AGT1 shall wear BA. He/she shall only enter the confined space without BA after he has

established from outside of the confined space that oxygen, flammable and toxic gas levels for

the whole space are within the criteria for non-BA entry (see Table 1) and there is a need to

carry out further safety checks in the space (e.g. establishing radiation readings from NORM or

nucleonic gauges) or if he is updating a valid Entry Certificate which has already certified the

space fit for entry without BA.

 If practicable, the AGT 1 shall wear a harness and a lifeline. This shall only be considered

practicable if the nature of the confined space is such that the attendant could hoist or drag out

the AGT 1 from the space if the latter were immobilised, and if the rope would not impede the

AGT 1 in making an unassisted emergency exit.

Note: It would require a winch to vertically hoist an average person from a space below.

Resuscitation equipment ready for immediate use shall be kept close at hand.

5.10 GAS TEST REQUIREMENTS

Testing must be carried out in accordance with the following requirements:

 Ventilation equipment must be shut off before the tests commence

 The atmosphere must be tested at the bottom, top, and the middle of all confined spaces

 The atmosphere inside must be continuously monitored while work is being conducted in the

confined space

 If the confined space is left for any reason, the atmosphere shall be re-tested before re-entry

may be permitted

5.11 TEST EQUIPMENT

Testing instruments must be within their calibration dates and operationally checked before and after

use in accordance with manufacturer specifications. Test records must be held on site.

5.12 CRITERIA FOR CONFINED SPACE ENTRY

The space shall only be classed as fit for entry without BA if:

 The oxygen and flammable gas levels are the same as measured outside in fresh air, and

 Toxic contaminants do not exceed current occupational exposure limits

 Also, the AGT1 shall confirm that there are no materials left inside which in his judgement may

give off sufficient quantities of vapour and fumes if disturbed, such that the atmosphere would

cease to be classed as fit for entry without BA.

5.13 WORK PERMIT AND CONFINED SPACE ENTRY PERMIT ISSUE AND VALIDITY

When the gas test has been completed, the Area Authority shall consider the results. He shall then

issue the appropriate Work Permit, cross-referenced to the Confined Space Entry Permit on which is

specified the period in which he considers it safe to enter the space, taking into account the nature of

the space, possible contaminants, type of isolations and the type of work proposed.

An Entry Permit on its own does not authorise entry for any purposes other than testing and

visual inspection by AGT1 only.

A separate Level 2 Risk Assessment shall be generated to support Work Permit for the work to

be carried out in the confined space including visual inspection by other disciplines.

The Entry permit shall be displayed at the job site. Entry points shall be barriered off when the

confined space is not manned.

Entry to the confined space shall commence and continue at any time during the period for which the

permit is valid. If the space is vacated during the period of validity, a gas test shall be undertaken

before re-entry. Alternatively, if continuous gas monitoring equipment has been in use throughout the

http://docs.bpweb.bp.com/dkAzSPU:/published/hse/documents/AZSPU-HSSE-DOC-00060-2.

Prior to issue of the CSE permit, the responsible competent person (AA) shall attend the work site in

order to verify the work scope, assess the hazards and check if control measures are in place,

including mitigation.

The scope, hazards, controls and mitigation measures shall be communicated in writing and signed

off by all involved in the task (a documented TBT). Both parties issuing the permit and accepting it

shall confirm that the workforce understands its contents, uses the correct equipment and ready to

stop unsafe work if required by situation. A copy of the CSE permit shall be retained on site for the

duration of the work for the benefit of the work force.

The contents of the CSE permit shall be also communicating to affected Operations and other

personnel in order to reduce the impact on their activities prior to commencement of the work. The

CSE Permit shall be countersigned by all AAA if applicable.

Personnel operating in remote locations may have limited access to facilities and other competent

personnel. It is particularly important that they have the skills, competencies and CoW knowledge

required to operate safely in the conditions they work in.

On completion or interruption of any permit including CSE, the worksite should be thoroughly

inspected and confirmed its safe state, i.e. the area should be cleared from debris, materials and

equipment, cleaned of spills etc. This shall be verified by the authorised person‟s (PA) signature.

The CSE activities as a part of CoW process shall include de-isolation, reinstatement and testing of

the system‟s integrity.

5.14 PROCEDURE FOR ENTRY INTO CONFINED SPACES WITHOUT BA

5.14.1 Confined Space Attendant

A suitably trained Confined Space Attendant shall be stationed at the designated entrance to the

confined space and shall perform the duties outlined in Section 4.0 paragraph 4.6.

5.14.2 Entrants

Entrants shall perform the duties listed in Section 4.0 paragraph 4.5. Entrants to the confined space

 Continuously monitor for oxygen, hydrocarbons and H₂S. This may be achieved by one of the

Entrants monitoring Crowcon Triple meter (or similar) to ensure that the conditions are not

worsening. If this should occur, the space should be vacated, ventilated and re-tested until

conditions have improved to within the limits set out on the Entry Permit.

5.14.3 Work Activity Affecting Entry without BA

Even though a gas test may indicate that a confined space is fit for entry without BA, if work is to take

place within that is likely to generate toxic or flammable vapours to such an extent that the

atmosphere cannot be kept free of contaminants by forced or natural ventilation (e.g. application of

paint coatings), the space shall be treated as not fit for entry without BA.

5.15 ADDITIONAL PROCEDURE FOR ENTRY INTO CONFINED SPACES WITH BA

5.15.1 Confined Space Attendant

The Confined Space Attendant shall perform the duties listed in Section 4.0 paragraph 4.6.

Additionally, where the space contains residual fluids (e.g. water) into which a person might fall so

that his face and BA are submerged, he shall be assisted by a rescue person who shall be stationed

at the opening in addition to the Confined Space Attendant, equipped to make an entry wearing BA so

as to give immediate help, if he considers it safe to do so.

5.15.2 Entrants

Entrants shall perform the duties listed in Section 4.0 paragraph 4.5. In addition, they shall wear

approved positive pressure BA and be trained in its use.

Note:

 Canister respirators shall not be used in any circumstances. Air-supplied apparatus shall be

used.

 All personnel expected to wear BA and carry out work at the same time are recommended to

be clean-shaven in order to provide a good seal between mask and face.

 If it is not possible to class the space as „fit for entry without BA‟, entry WITH BA may be

permitted, subject to the criteria in Table 1 and in accordance with the additional precautions

below:

o Approved positive pressure BA is worn.

o Authorisation for ENTRY WITH BA has been given.

o Where practicable, retrieval gear is worn.

o The Entry Attendant must be stationed outside the space entrance at all times.

o Rescue and reviving equipment and qualified personnel shall be readily available.

5.16 CLEANING

5.16.1 Removal of Sludge, Scale and hard Deposits

After a tank or vessel has been opened up, as much oil, sludge and scale as possible shall be

removed by means of bailers, squeegees etc, aided, if convenient, by adequately earthed water

hoses. As much removal as possible should be carried out from the open manhole door, but invariably

it will be necessary to enter the tank/vessel to remove all sludge and scale.

Earth sumps or suitable containers shall be provided for the reception of oil or oily sludge. This

material shall be contained and disposed of in a safe and environmentally acceptable manner.

All pyrophoric scale shall be disposed of in an approved manner. During the time that it is exposed to

Where there are hard deposits, necessitating the use of chipping tools, the PTW shall specify that the

surface being chipped must be kept thoroughly wetted during the operation.

Where high-pressure water jets are used in the removal of sludge and scale, only specifically trained

operators shall be used. Where standard water hose and nozzles are used to wash out, the nozzles

shall be earthed.

5.16.2 Use of Chemical Cleaners

If chemical cleaners are to be used then the MSDS for the chemical shall be consulted and a risk

assessment (COSHH) conducted prior to use. In particular, additional ventilation or respiratory

protection may be required.

When introducing a chemical into a confined space, the compatibility of that chemical with the

contents of the confined space must be checked. If any doubts exist regarding the compatibility of a

chemical, the HSE Department shall be consulted.

Sludge and spent cleaning fluids must be contained and disposed of in a safe and environmentally

acceptable manner.

When chemical cleaning takes place there is a possibility for the production of toxic gases, including

H₂S. Therefore a closed drain system, outside the confined space, shall be used for the disposal of

effluent from these operations. Personnel engaged in these operations shall wear suitable chemical

protective clothing/equipment and suitable toxic gas monitoring/warning devices shall be provided.

5.16.3 Removal of Trapped Oil or Vapour

When repairs are to be carried out within a tank or vessel, care shall be taken to ensure that oil is not

trapped inside internal structural members. Any hollow supports or bracing steelwork exposed to

hydrocarbon should be carefully drilled at the lowest and highest point to detect the presence of oil. If

it is found, the hollow member must be purged by one of the methods discussed above before work

on the tank or vessel is allowed to proceed.

Any linings or wear plates attached to the shell of a tank or vessel may trap liquid hydrocarbons

behind them. This liquid can percolate into the vessel or tank by way of minute cracks. Therefore, the

vessel or tank shall frequently be tested to ensure that it remains gas free.

5.17 VENTILATION

5.17.1 „Cleaning-out‟ Doors

Where confined spaces are provided with clean out doors, these doors shall be opened after purging,

and the confined space thoroughly ventilated.

5.17.2 Use of ventilation Equipment

Ventilation shall preferably be accomplished using a positive method of mechanical ventilation that is

arranged to:

 Introduce sufficient fresh air and remove contaminants from all pockets or corners of the

confined space

 Avoid re-circulating contaminated air

Even after the confined space is cleaned and ventilated, the mechanical ventilation equipment must

be kept operating to provide secondary protection:

 In case of accidental introduction of harmful substances

 To remove contamination or heat that may be produced by the work

(e.g., welding and cutting, painting, coating)

The atmosphere must continue to be monitored for toxic gases, fumes and airborne contaminants

while personnel are inside the confined space.

5.17.3 Ventilation Air Source

The ventilation air used will be from either:

 An electrical blower approved for a Zone 1 hazardous area, or

 An air driven blower

The air intakes for these devices shall be located where no contaminants may enter the stream.

5.17.4 Disposal of Confined Space Atmosphere

Outlets for power driven blowers, pneumatic air inductors, or air/steam inductors used to draw

vapours out of a confined space must be directed to a safe place far from possible sources of ignition.

5.17.5 General Ventilation

When welding (especially MIG/TIG) or other work is to be carried out in a confined space, precautions

shall be taken to ensure that an adequate flow of fresh air is available and that welding fumes are

removed. Great care shall be taken to ensure that the airflow is always away from the breathing zone

of the welder and that contaminated air does not 'short circuit' back to the welder.

Where exhaust ventilation is used in a confined space, the extracted air shall be diverted well away

from the confined space so that replacement air shall be fresh. When adequate ventilation cannot be

provided, approved breathing apparatus or a suitable facemask supplied with fresh air shall be worn.

Compressed oxygen or instrument air shall never be used to ventilate a confined space.

5.18 LIGHTING AND PORTABLE TOOLS

5.18.1 Temporary Lighting

The following precautions shall be observed when using temporary lighting:

 Where the confined space has not been declared gas free, air driven flameproof lights or

certified battery powered torches shall be used. Lights must be certified for a Zone 1 (Division

1) area.

 Confined spaces, which have been certified gas free but where flammable residues could

remain, may be illuminated as above; or by extra low voltage (25V ac) portable lighting

equipment, approved for use in a Zone 1 (Division 1) area.

 Where the confined space has been cleaned of all flammable residues and certified gas free, or

is a confined space by virtue of restricted access alone and there has never been the possibility

of it containing a flammable atmosphere, standard low voltage industrial lighting may be used.

 The supply cables to the (approved for use in a Zone 1 (Division 1) Area) transformers, for

extra low voltage portable lights, must always be supported above ground and the transformers

never taken inside the Confined Space.

 Particular attention must be paid to the protection of cables passing through doors and entry

points.

5.18.2 Tools

If the atmosphere inside the confined space requires BA to be worn (see Table 1) because of the

presence of hydrocarbon, no electrical tools must be used by the entrants. Air-driven tools only may

be used. Tools with the potential to produce sparks, e.g., grinders or needle guns, shall not be used.

5.19 WELDING

Before any welding, cutting and grinding may be carried out in a confined space; the space shall be

proved completely gas free, and free of all flammable residuals.

5.20 JOB COMPLETION

If the vessel is unmanned for any period of time the entry points shall be barriered off. The Entry

Permit must be cancelled upon completion of the entry and after all entrants have exited. At the end of

a job, a thorough check must be made by Area and Performing Authority to ensure that no personnel,

tools or equipment have been left behind.

5.21 RESCUE

Emergency Response arrangements shall be considered in the Risk Assessment and shall cover,

rescue, resuscitation, and treatment of casualties.

5.21.1 The Rescue Team

The Rescue Team should respond immediately to rescue calls from the Attendant or any other person

recognising a need for rescue from the confined space.

The Rescue Team must be trained to perform the assigned rescue functions. In particular, members

must be trained in the proper use of personal protective and rescue equipment, including breathing

apparatus. Also, at least two Rescue Team members shall be certified in first aid and in Cardio-

Pulmonary Resuscitation (CPR).

5.21.2 The Rescue Plan

The rescue plan should be written to include as a minimum:

 A means of raising the alarm by the Confined Space Attendant or other person observing an

emergency situation

 An assessment of the hazards associated with the confined space

 The required gas testing/monitoring equipment

 The personnel required to perform the rescue

 All precautions to be taken while in the confined space

 The required personnel protective equipment (PPE)

 The required rescue equipment

 The required tools and any other special equipment
