Examination and Discard Criteria

Slings constructed in man-made fibers are easily damaged and can be sensitive to chemical

attack.

Strength is lost if there are any cuts, tears, abrasion, fraying and burst stitching, therefore

this sling type requires close examination by a competent person for any signs of damage

prior to every lifting operation.

Endless Round Slings are manufactured with an outer protective sheath, which prevents the

ingress of chemicals and dirt, which can lead to the deterioration of the sling fibers in

service. The protective sheath also makes the examination for defects more difficult and

onerous than that of the Flat Webbing Sling.

Man-Made Fibre Endless Round Slings:

Endless Round slings shall only be used for general purpose lifting duties on the site

providing the sling has a current certificate of conformity and there is an approved lifting plan

and risk assessment for the operation. Site Lifting Coordinator shall inspect slings for

suspected or evident damage prior to use. The sling(s) shall be physically removed and

destroyed if any damage is suspected or evident.

Certification for this type of sling is valid for 6 months after which time it will be removed from

service and destroyed.

Man-Made Fibre Flat Webbing Slings:

Flat Webbing Slings shall only be used for special lifts where the component to be lifted can

be damaged by the use of conventional wire rope slings. Flat webbing slings shall be used

for lifting duties on the site providing the sling has a current certificate of conformity and

there is an approved lifting plan and risk assessment for the operation. Site Lifting

Coordinator shall inspect slings for suspected or evident damage prior to use. The sling(s)

shall be physically removed and destroyed if any damage is suspected or evident.

Certification for this type of sling is valid for 6 months after which time it will be removed from

service and destroyed.

Water Quality Criteria

Bacteriological Quality

Analysis

Analysis shall be carried out by the BP Medical Contractor or an independent

laboratory (Medical Microbiology).

Potable Water

Bacteriological samples shall initially be taken at least monthly from potable water

supplies. This may be relaxed to quarterly for potable waters if six successive samples

are satisfactory. Occupational Health Department may require more frequent testing if

two successive samples fail the test.

Domestic Water

Water that is used for domestic supplies other than drinking and cooking shall be tested

every six months.

Analysis results

In the case of an unsatisfactory result, the laboratory shall inform the Health and Safety

department immediately. The Health and Safety department shall then advise the site

and recommend suitable remedial action to be taken to restore water purity. The

actions which will normally be recommended are detailed in Table 1 Biological

Analysis - Criteria and Actions; more detailed advice will be provided by the Health

Team upon receipt of unsatisfactory results:

Chemical Quality

Chemical Parameters

Chemical parameters shall be determined and compared to the standards defined

within this document. Where any of the maximum acceptable levels are exceeded then

advice will be given to the user by the Health Team Leader on the:

 suitability of the water for use or consumption

 possible remedial action to be taken.

Pesticides

Pesticide contamination is a serious problem with onshore water supplies in the

Caucasus. Solvent extraction followed by gravimetric analysis provides only a course

evaluation of pesticide levels and is subject to interference by other chemicals.

While it may be used as a course indicator, pesticide determined at levels greater than

50ug

/ litre by solvent extraction and gravimetric techniques must be further

investigated using gas liquid chromatography to establish the nature of the compounds

detected. Limits for individual pesticides shall be as per World Health Organisation

Guidelines, Annex 2 Table A2.2 C.

Analysis

Water from all sources shall be subjected to a chemical analysis before use and

thereafter annually. The full analysis in Table 2 Chemical Contamination Limits shall be

carried out for the first test on a new water source. Thereafter the list in normal type

shall be carried out on all samples.

Note: The values given in Table 2 are guideline values based on toxicological

studies and are not absolute limits. However, any potable water supply with

values above the limits quoted will require further investigation before the

water can be cleared for use.

Tests designated in italics will only be carried out on subsequent samples if:

 levels at or near the quoted criteria are detected in the first test

 a significant risk of contamination is determined by Health and Safety

department (for example, all samples from the well at Supsa must be tested for

arsenic since this is known to be present in the ground waters in this area).

Note: Potable water supplies from BP operated wells or treatment plant shall initially

be tested quarterly. This can be relaxed to an annual test once consistent

composition can be demonstrated.

Water Quality Monitoring

Water Sampling

Water Sample Collection

Water may be supplied from:

 public mains supply

 supply vessel that has loaded the water in port

 on-site fresh water generation (for example reverse osmosis plant)

 wells

 local source by road tanker.

In all cases the quality assurance and sampling procedures are the same.

In most cases water samples will be taken by an analyst from the testing laboratory or

a member of the medical team trained in water sampling.

Well Purging

If sampling well supplied water, well conditions must be stabilised by purging before

taking the sample.

Note: If a well has been operating on a normal day-to-day basis, then purging of

the well prior to sampling is not necessary.

For a high yielding well, if the well has been out of operation for more than 24 hours,

remove at least three well volumes of water from the well casing.

In moderate to high yielding wells the purging is complete when pH and temperature

have stabilised to within 10%.

For low yielding wells that are prone dewatering, the yield will not be restricted by

parameter stabilisation and will be sampled after sufficient recharge has occurred after

pumping down.

Record results of the well purging operations.

Collecting samples from taps and open pipes

Note: Avoid taking water samples from taps that have a swivel nozzle fitted or taps

that leak.

The following guidelines shall apply for all samples taken from taps and pipes:

1. Remove aerators , screens or similar attachments.

2. Sterilise the end of the tap or nozzle with a small flame (a cigarette lighter is

ideal).

3. Run water at a steady rate (without splashing) for at least 2 minutes before

sampling

4. Do not adjust the flow rate while taking the sample.

5. Carefully open the sample container prior to collecting the sample and close

immediately the sample has been taken.

6. Do not touch the mouth or inside of the container or cap and do not lay the cap

down.

7. Do not rinse out the container.

8. Label the container as for a chemical sample and immediately refrigerate but do

not freeze.

Collecting Samples from Tanks

Note: The risk of contaminating the sample is much higher when taking a dip

sample. If possible sample from a tap rather than taking a dip sample from a

tank.

To take a dip sample:

1. Hold the container at the bottom and remove the cap from the container.

2. Plunge the container mouth down into the water.

3. Tilt the container and allow to fill slowly.

4. Replace container cap immediately after collection is complete.

5. Label the container and immediately refrigerate but do not freeze.

Sampling Procedure for Microbiological Analysis

Because biological samples are required frequently, field staff will be asked to collect

samples and despatch them to the laboratory. Microbiological samples can be easily

contaminated which may lead to a false positive result. Therefore, only sample

containers provided by the testing laboratory or medic may be used for microbiological

samples. These containers have been sterilised prior to despatch. and must be

carefully handled to prevent the introduction of bacteria from the hands or work

surfaces.

In addition, sterile surgical gloves should be worn, if available, when taking samples.

Water Sampling Procedures for Chemical Analysis

Samples for chemical analysis shall be collected from a tap located on the discharge

piping downstream of all water treatment units.

Prior to sampling for chemical analysis, the following guidelines shall be applied:

1. Check and calibrate all instrumentation required for field measurements

against known standards.

Field measurements will be made of:

 water level in the well or storage tank

 pH

 temperature (^oC)

 electrical conductivity (eC)

 dissolved oxygen (DO).

2. Decontaminate all required sampling equipment.

3. Record well water or storage tank levels in order to provide a record of the

groundwater / supply conditions at the time of sampling.

In addition, immediately prior to sample collection, measure and record field

parameters. Field parameters are:

 pH

 temperature (^oC)

 electrical conductivity (eC)

 dissolved oxygen (DO).

Sample Handling, Packing and Transportation

In most instances, a chemist from the testing laboratory or a medic from the company’s

medical contractor will visit the site to take samples. When this is not the case the

following custody and packaging guidelines must be followed:

 Samples will be stored in accordance with the requirements of the sample

preservation conditions specified by the testing laboratory.

 The containers provided by the laboratory shall be used for all samples and the

laboratory’s instructions for taking the sample shall be strictly followed.

 After sampling, all samples will be stored in sealed sample containers in a

refrigerator to maintain specified sample temperatures until transportation.

Note: Samples will not be frozen as this may fracture glass sampling

containers. Samples for metals analyses do not require refrigeration.

 Prior to transportation of the samples for analysis, the sample containers shall

be packed into thermally insulated containers to maintain the specified

temperatures during the transportation period.

Note: Sample containers must be kept in refrigerated storage or an ice

packed cool box during transportation.

Sample Documentation

Each sample is given a unique four-digit sample reference number. Sample information

will be transferred from the field record onto the Chain of Custody Record (see Figure 1

Water Custody Transfer Record) which forms the basis for communications between

the field and the analytical laboratory.

The Chain of Custody Record is completed by the sample taker for the analytical

laboratory so that the analyst is provided with relevant sampling information. This

document is completed prior to shipping the samples to the laboratory.

One copy of the completed document shall be kept by the sampler; a second copy

accompanies the sample container and a third copy shall be faxed to the analytical

laboratory.

Maintenance and Monitoring

The Requirement for Maintenance and Monitoring

Although the quality of water generated by reverse osmosis or distillation plant and the

quality of bunkered water is generally high, it is unlikely to be entirely free of suspended

solids and micro-organisms and as a result, storage and distribution systems are

ultimately affected by the build-up of sediments and harmful bacteria. When conditions

are favourable, harmful organisms that have colonised the system will multiply and

seriously contaminated water may be released to the workplace.

An appropriate maintenance regime is essential to prevent any deterioration in water

quality. Table 4 summarises the main contamination areas and the basic steps to be

taken to avoid or minimise bacteriological proliferation.

Potable Water System Maintenance Log

To ensure that a suitable system of maintenance is put in place Site Managers shall

identify a person from within their organisation to be responsible for producing and co-

ordinating a Potable Water System Maintenance Log. In addition to the information

given in Table 1 Biological Analysis - Criteria and Actions more detailed information

may be required in the log depending on the type and complexity of the system.

Usually, a relatively simple record should suffice which should include:

 identification of those responsible

 system operating procedures and schematic/plan

 legionella risk assessment

 maintenance and monitoring procedures (including testing schedule and record

keeping)

 log of monitoring data (see Table 3 Maintenance and Monitoring Schedule).

The log shall be regularly reviewed and updated as necessary to reflect changes and to

verify that all planned preventative measures are being fully and effectively

implemented.

Emergency Water Systems

In addition to the main potable water distribution system some consideration should be

given to emergency services such as showers and firefighting systems involving

sprinklers which may be permanently charged with water, often forming long ‘dead-

legs’ and with the possibility of temperatures higher than

20ºC. However it is

considered that in the event of the system being activated, the risk, especially from

legionellosis (see Paragraph 6) would be insignificant compared to that from chemical

contact or fire.

There may be some risk during the testing and maintenance of these systems.

Therefore the control measures applied to cold water systems should be adopted so far

is practicable. Testing procedures adopted should minimise the generation of aerosols,

and the tests should be conducted when the minimum number of persons are likely to

be affected.

Legionella

Description and Causes of Legionnaires Disease

Legionella pneumophila is the bacteria that can cause the condition legionellosis or

‘Legionnaires’ disease, a severe form of pneumonia. Infection is attributed to inhaling

aerosols of legionella contaminated water. Infection by drinking or person-to-person

spread has not been documented. Risks of developing the disease are believed to be

low due to its need for aerosols, suitable infective doses and susceptible individuals (for

example those in poor health).

Legionella organisms frequently colonise domestic hot and cold water systems,

particularly humidifiers, calorifiers and shower heads where they can multiply under

certain conditions (for example, temperatures between 20 - 40 C, stagnant water and

presence of biofilm/scale).

Risk Assessment

A Risk Assessment shall be carried out and suitable controls to prevent any harm to

health must be put in place. For detailed guidance on how to assess the risks and

control options available see Paragraph 1.4 References. Generic Risk Assessments

may be used for similar installations.

Risk Reduction Strategy

The strategy to reduce the risk of legionellosis, is to design, maintain and operate water

services under conditions which prevent or minimise the proliferation of legionella.

Design

 Protect systems against external contamination.

 Avoid water stagnation by careful sizing of system capacity.

 Eliminate dead legs.

 Provide efficient heating for hot water systems & adequate insulation for all

pipes/fittings.

 Tanks, calorifiers etc. should be readily accessible for cleaning.

Operation

 Establish effective control levels for temperature, biocide etc.

 Ensure delivery of effective control levels by measurement.

 Maintain records of the procedures /precautions.

Maintenance

 Water system components require routine cleaning/maintenance.

 A suitable maintenance strategy is outlined in Table 4 Legionella Control -

Criteria and Actions.

Screening For Legionella

Accommodation units with shower facilities must be sampled for the presence of

legionella annually using a water sample from a shower head. The acceptance criteria

are given in Table 4 Legionella Control - Criteria and Actions.

Route Identification and preparation

Locating and Marking Existing Pipelines

Note: At locations where there is hydrocarbon or a suspected leak a gas survey

must be carried out before pipeline location activities begin.

Prior to the commencement of any excavation a site survey shall be carried out in order

to:

 locate, identify and mark any existing pipelines and foreign services and utilities

and any cathodic protection system components, using pipe locating equipment

and hand excavated trial holes

 peg out the pipeline routing

 define and log the point of excavation.

Pipeline Crossing Points

Requirements

Construction traffic and other plant shall cross the pipeline only by:

 public roads

 previously agreed and clearly marked crossing lanes or bridges.

Construction

All crossing lanes shall be fenced on both sides over a width to be specified and

agreed by the Pipeline Patrolman as far as is reasonably practicable as dictated by

local conditions and acts of vandalism. These fences shall be returned along the edge

of the wayleave strip for a distance of 6 m away from the crossing.

Where it is necessary at crossing points to install a temporary bridge to protect the

pipeline. Such a bridge will consist of the laying of steel plates of adequate thickness

with hard core laid in, or an approved sleeper raft, or a combination of these methods.

The design and construction of such bridges and crossings shall be by a competent

person or approved civil engineering subcontractor where it is deemed necessary.

Markings

Any temporary crossing or bridge, must be clearly marked by appropriate notices and

flags, and additionally with lights at dusk, at night or in foggy conditions.

Site Safety

Access and Security

Guards and Barricades

Open excavations in a plant or near public areas must be

 attended by a watchman

or…

 protected by a barricade and mark with a warning sign.

All other open excavations should be attended by a watchman, marked or barricaded. If

there is a recognised chance of people or cattle falling into the excavation, a decision

may be taken regarding the use of a night watchman.

Note: If a night watchman is used, he shall be equipped with appropriate

communications and shelter for use in case of prowling animals, sickness or

other emergency. Vehicle for night watchman to be provided as far as is

reasonably practicable.

Fencing, Gates and Safety Notices

Erection of stock fencing, gates and bunting safety notices, etc., shall be undertaken

over access ways and worksites.

When the pipeline is exposed outside normal working hours a security presence will be

required over and above that of the normal construction personnel. This service shall

be supplied by a BP approved Contractor.

Vehicle Traffic

All light vehicles shall be fitted with “DRIVE RIGHT” vehicle monitoring software.

Vehicular traffic should not operate within 1 m of a trench or excavation. Vibration

created by traffic may cause cave-ins.

Personnel

Warning: Workers should not stand on the edge of an excavation or between a

pipeline ditch and strung pipe resting on skids. The bank might slough,

or temperature changes in the pipe could cause skids to fail and allow

the pipe to fall.

Protective Equipment (PPE)

With temperatures experienced in Azerbaijan and Georgia the use of Inherently Fire

Resistant or Flame Retardant Coveralls during summer where personnel are working

all day outside could be unbearable. An alternative to IFR/FR coveralls for the low flash

risk applications is 100% cotton. Personnel involved in specific work activities should

wear Flame Retardant coveralls.

During all activities on site all personnel shall wear minimum PPE (helmet, safety

boots/shoes, fire coveralls, and eye protection).

Personnel involved in specific work activities shall wear additional PPE to suit the

requirements of the work as agreed/detailed at the pre-work toolbox talk.

Excavator Operators

Only experienced operators shall operate the excavating equipment.

Banksmen

Trained and qualified banksmen shall attend all operations involving excavating

equipment and movement of heavy plant to prevent personnel entering the field of work

and to ensure safe working of the equipment.

Equipment

Type and Location

All equipment shall be checked and registered on the appropriate checklists and

registered in accordance with the site operating procedures. All operatives’ certificates

shall be checked and logged prior to works commencing.

Warning: Machinery vibration may cause cave-in. No running plant shall be

located within 1 m of an excavation.

Equipment Inspection

Equipment shall be inspected daily and maintained as necessary to ensure that it is in

good working order. This includes the inspection of brakes, pivot pins, hydraulic

cylinders, hoses, snap rings, main attaching bolts, etc.

Adjustments and Repairs

Refuelling

A method statement covering spill containment and management of personnel injury

risks shall be prepared for all refuelling operations

In all cases, equipment shall be shut down prior to being refuelled.

Lighting

All lighting shall be either explosion proof or located outside Zone 2.

The Use of Mechanical Equipment Near Overhead Power Lines

Introduction

All personnel working near overhead power lines with a machine or mechanical

equipment shall be made aware of:



the dangers associated with power lines



the precautions they should follow to deal with those dangers



what to do if they make contact with a power line.

Warning: Physical contact with high-voltage overhead power lines is likely to be fatal

or cause severe and irreversible maiming.

It is impossible to say whether an overhead cable is a power line or a

telephone line from observation alone. The only sure method is to make

contact with the line owner.

Safe Vertical Working Clearance

The minimum safe working distance between mechanical excavation equipment and

live overhead power lines will vary according to:

 type of power line (for example, insulated or uninsulated)

 voltage carried by the power line

 ground and weather conditions.

To establish and maintain safe vertical working distances between mechanical

equipment and overhead power lines the following practice shall always apply:

1. Establish and record the maximum vertical reach of all machines on site.

2. Identify the routes of all overhead lines on or near the land to be excavated and

clearly mark these routes on site plans.

3. For each overhead power line, identify the line owner.

4. From the line owner find out:

a. if the line can be conveniently made DEAD

b. the line type (for example, insulated or uninsulated)

c. the voltage carried

d. minimum safe working clearance for mechanical machinery operating

near the power line.

5. If the line cannot conveniently be made DEAD then the established minimum

safe operating clearance shall be adhered to at all times.

Reducing the Risk from Overhead Power Lines

Risks associated with working close to overhead power lines can be reduced by:

 taking care not to damage poles and stays

 fitting shorter radio aerials or repositioning existing ones on high machines so

they cannot cause danger

Originating Dept: HSE

 carrying long items (for example, pipes or ladders) horizontally and not storing

pipes or other materials and equipment near or under power lines and their

supports

 designating safe areas for high-risk activities; for example, tipping trailers

 using barriers and goalposts: by erecting goalposts and barriers, machines

which have to pass beneath lines can be limited to a safe height - an option

especially suited to gateways and tracks.

If Contact is made With an Overhead Power Line

 Never touch an overhead line - even if it has been brought down by machinery,

or has fallen through other means.

 Never assume that lines are dead.

 When a machine is in contact with an overhead line, electrocution is possible if

anyone touches both the machine and the ground. Stay in the machine and

lower any raised parts that are in contact or drive the machines out of the lines if

you can.

 If you need to get out to summon help or because of fire, jump out as far as you

can without touching any wires or the machine - keep upright and away from

the machine.

 Get the line owners to disconnect the power supply. Even if the line appears

dead, do not touch it - automatic switching may reconnect the power.

Working Hours

Excavation work shall only be carried out during daylight hours where practicable. If the

task overruns dayshift then the area will be barriered off and illuminated using

approved out side site lighting. Preferably this should be a mobile tower, diesel driven

arc light if available. These are additional requirements in addition to the site being

fenced off.

Fires

Storage of material for lighting of fires within the pipeline wayleave or in the vicinity of

above ground installations associated with it is not permitted.

Pre-excavation requirements and Procedure

Note: Excavation activity should preferably be undertaken in the summer as far as

is reasonably practicable, in order to minimise both ground disturbance and

soil compaction.

BP Consent

Excavations may only take place on BP managed or owned property with formal

consent from BP, with 72 hours notice as far as is reasonably practicable. Where

excavation is to take place, a Permit to Work and an Excavation Certificate shall be

obtained before work begins.

Landowners

Ensure that access has been granted by the landowner, that a pre-entry survey with

photographs has been done and that compensation, access route and area protection

have also been agreed.

Landowners and neighbours in close proximity to the proposed excavation must be

informed that work is about to begin and that the inspection is of a routine nature.

Note: This requirement may be negated under an emergency situation.

Third Party Services

Owners of third party services shall be contacted before the excavation of their services

begins. A No Objection Certificate shall be obtained when applicable.

Excavation Boundaries

The extent of required excavation shall be clearly marked out prior to commencement

of the work.

Drainage Patterns

Prior to excavation, existing drainage patterns should be noted, so that subsequent

drainage schemes can mimic the original pattern (see 9.1 Drainage).

Excavation design requirements

Access

Whenever personnel will be in an excavation, ramps, stairways or ladders should be

kept within 7.6m of workers for all excavations over 1.2m deep.

A ladder, stairway or ramp shall be installed on both sides of the pipeline to provide

ingress and egress for workers.

Windsocks

Wherever the presence of hydrocarbons is reasonably suspected, for example in all

Red Zones, windsocks or flags must be positioned on both sides of the excavation in

order to determine wind direction.

Slope Requirements and Ground Type

Excavations deeper then 1m shall have the sides benched or battered back, as per

Figure 1 Minimum Acceptable Excavation Design Profiles for battered profile or figure 2

for benched profile. Shoring shall be used when required and site specific drawings, for

approval by BP, shall be prepared.

Except in stable rock, all excavations must be shored, shielded (i.e., trench box),

benched or sloped if:

 the excavation is 1.2m or more in depth

 a worker’s head is below the level of the excavation when bending or stooping

to perform the work task - as far as is reasonably practicable and/or required by

Risk Assessment.

tracer cables that are within the excavation zone, overhead and below ground,

must be located and identified).

 The Task Workpack, if applicable, are approved and onsite.

In addition, the procedures listed in

1.3 Related Procedures should be consulted

wherever there is a potential for:

 possible energy release

 the presence of hydrogen sulphide or hydrocarbon gas

 an oxygen deficient environment

 the presence of carbon dioxide or other chemical substances.

Environmental Impact Assessment

For new excavations in areas not previously excavated or areas containing refurbished

sections of the old GIOC pipeline, before any excavation

(mechanical or non-

mechanical) may begin, an Environmental Impact Assessment must be conducted to

establish whether or not the area of excavation is of ecological or archaeological

importance. An Environmental Impact Assessment Report

/ Letter

(based on the

findings of the assessment) shall be sent to the State Committee of Ecology (SCE) for

approval. Only when this report / letter has been approved can excavation commence,

and even then, only in accordance with any requirements specified by the SCE.

Note: Protection of Historical and Cultural Monuments shall be implemented in

accordance with the EMS Manual and Procedure No. EP - 003

Site Supervisor - Assessment Responsibilities

The Site Supervisor shall review archaeological maps, ensure that the Environmental

Adviser is notified of any scheduled ground disturbance (inside and outside the right-of-

way) and shall ensure all relevant personnel are made aware of the resulting

Environmental Assessment.

Environmental Adviser - Assessment Responsibilities

Upon notification of the intended excavation, the Environmental Adviser shall:

 provide the Site Supervisor with GIS information regarding natural and

archaeological features on the site

 provide the Site Supervisor with GPS coordinates and photographs of any

important features

 conduct a presentation identifying relevant natural and archaeological features

on the site. Attendees for the presentation shall include the Site Supervisor and

machinery / excavator operators.

Excavation Procedures

Note: No excavation shall be performed:

 without a BP representative being on site as far as is reasonably practicable

 until adequate communications with management and/or the emergency

response team are assured (the communications protocol to be adopted

shall be included in the Emergency Response Bridging Document) and/or in

the relevant operations procedures).

Note: No mechanical excavation shall take place closer than1m to any existing

live pipelines, cables, services, that belong to other parties. Use of

mechanical excavation to within 1m is subject to said pipelines, cables or

services being identified, located and suitably protected.

Excavation Inspections

Where personnel are required to work in excavations of 1.2m or deeper a safety

inspection by a competent person must be carried out on each shift as follows:

 before work is started

 after rainstorms

 after other occurrences which may increase the hazard of cave-ins.

All high-risk excavations as defined by the Risk Assessment must be attended by a

geo-technical engineer/person trained in soil analysis.

Toolbox Talks

A toolbox talk shall be carried out prior to works commencing with all parties involved in

the works. Talks shall be carried out during the works when the initial shift handover

takes place and when new works come on site.

Note: Toolbox talks shall be recorded.

Non-Mechanical Excavation

Once the position of the pipeline has been found, mechanical excavation may proceed

down to 500mm from the top of the pipe, leaving the remainder to be removed by hand.

This also applies to each side of the pipe except that the last 1000mm is to be removed

by hand. Machine excavation down to a depth of 500mm to top of pipe is only allowed if

combined with hand excavation as follows:

 Hand excavate a slit trench across the intended excavation up to a depth of

300mm

 Probe the hand excavated area to confirm the pipeline is at 500mm or greater

depth

 Machine excavate the remaining area to a depth not exceeding the depth of the

hand excavation

 Hand excavate a slit trench as above, probe and the if pipe cover below depth

of hand excavation is greater than

500mm again machine excavate the

remaining area to a depth not exceeding the depth of the hand excavation

 Repeat the above until a cover of 500mm over the pipeline remains. This shall

then be remove by hand excavation only.

Note: An entry certificate will be required for work in an excavation that is deeper

than 1.2m.

Note: Excavator buckets shall not be fitted with teeth during excavations in the

vicinity of pipelines or any other service.

Soil below the pipeline shall be removed by hand to the side of the excavations where it

can be mechanically removed.

If the pipeline at any time is exposed by excavation, it shall be properly supported and

protected against damage to the satisfaction of the Area Authority or BP representative.

On completion, permanent support shall, if necessary, be constructed to avoid future

settlement.

Temporary supports shall be installed under exposed services, where required and the

Contractor shall submit a sketch of proposed support for approval prior to excavating.

To avoid damage during work, any exposed part of the pipeline shall be protected by

cladding (for example, timber) as directed by the Area Authority/BP representative and

any damage to the protective wrap/coating of the pipeline, whether existing or caused

by excavation work, etc., shall be brought to his notice.

Mechanical Excavation

Before machine excavation begins

 Pipelines, should be depressurised as far as is reasonably practicable, and

 hand digging should be completed around pipelines, utilities, and cathodic

protection system components.

Note: Use caution when excavating around live lines and / or lines that may be

severely corroded.

Note: Excavator buckets shall not be fitted with teeth during excavations in the

vicinity of pipelines or any other service.

Operating restrictions

The following are operating restrictions for excavating equipment.

 Tracked vehicles should be used in preference to wheeled equipment on the

side of the excavation to minimise soil compaction.

 Equipment must be operated within its rated capacity.

 Personnel must stay clear of excavating equipment while in operation.

Examples of unsafe areas include: under or beside the bucket of a backhoe,

near hydraulic rams of a bulldozer, etc.

 Roll Over Protective Structure (ROPS) is required by PUWER 98 to be fitted on

any mobile equipment as far as is reasonably practicable.

Decision whether or not ROPS is required, is based on pre-job Risk

Assessment and exemptions from this rule are as follows:

o The ROPS would increase the overall risk to safety

o It is not reasonably practicable to operate the mobile work equipment

with such a device fitted

o If mobile equipment was purchased for use in the business before 5

December 1998.

 A seat belt must be installed on equipment manufactured with a ROPS.

 Do not use equipment if the ROPS has been removed.

 Avoid using the full reach or swinging a loaded bucket to the downhill side.

Note: This will prevent upsets when operating in a slope.

 Attach towlines at a point below the rear axle.

Note: Attaching above this level increases the risk of rollover.

Waste Management

Waste management on the excavation site shall be implemented according to the EMS

Manual and Procedure No. EP 80.

Power Lines

Before operating equipment, all utility lines and overhead power lines must be located

and identified.

Note: See 4.5 The Use of Mechanical Equipment Near Overhead Power Lines.

Hydrocarbon Pipelines

Mechanized excavation in close proximity to hydrocarbon lines poses an increased risk

of fire/explosion in the event of hydrocarbon release.

Note: Mechanical excavation shall not occur within 15.2m of an open flame, such as

a flare, an equipment burner without a flame arrester, cutting torch, etc.

Excavated Materials

Excavated material shall be placed at least 1m away from the edge of the excavation

and shall be stockpiled within the Right of Way area.

Topsoil

The stripped topsoil shall be stored for re-use away from the side of the excavation and

separate from the sub-soil.

The height of stored soils should be limited to 2m in order to reduce erosion problems

and prevent the development of anaerobic conditions within the stockpile. Weed growth

may need to be controlled by spraying with approved herbicides.

Warning: Do not pile topsoil under overhead power lines.

Subsoil

The stripped sub-soil shall be stored for re-use away from the side of the excavation

and separate from the topsoil.

Warning: Do not pile subsoil under overhead power lines.

Contaminated Soil

Note: Any excavation where contaminated ground is encountered shall have a

Hazard Risk Assessment completed. This Risk Assessment shall take into

consideration the duration that the excavation is expected to be open.

All excavations in contaminated ground conditions will be bounded to prevent the

ingress of surface water and shall be monitored on a regular basis for any change in

the level of the ground water or liquid level (particularly in the event of heavy rainfall).

Monitoring shall be on a 24hour basis in high-risk areas as determined by the Hazard

Risk Assessment.

Excavated contaminated soil shall be placed into a bounded area lined with heavy -

duty plastic sheeting to avoid seepage and shall be segregated from uncontaminated

soil.

All excavated soil grossly contaminated with hydrocarbons and not re-used shall be

transported to a designated treatment facility approved by BP.

Where work in an area of contaminated ground cannot proceed in accordance with the

schedule, consideration will be given to back-filling the excavation

Backfilling Procedures

Preparation

Notice, Approval and Supervision

Adequate notice shall be given to BP of the intention to backfill within the wayleave of

the pipeline.

In addition, backfilling of the trench shall not commence without the approval of the Site

Team Leader or the Area Authority/BP representative and shall only proceed in the

presence of the Area Authority/BP representative. The Area Authority/BP

representative shall advise on the specification of the backfill and the method of

consolidation around the pipeline.

Backfill Materials

No perishable materials such as vegetable growth, timber bush, etc are to be filled into

the trench.

Special care must be taken to prevent any stones, cinders, slag, debris of made up

ground or other harmful matter such as will be likely to set up corrosion from coming

into contact with the pipe.

Stony or gravely trenches are frequently a problem at river crossings and old riverbeds.

If rock, stones or gravel are present in the bottom of the trench then fine material is first

placed above the pipeline to ensure that only fine material surrounds the pipe.

Backfilling Guidelines

Backfilling operations in well-compacted layers should be carried out in such a manner

as to prevent heavy loads passing over the pipeline. Allowance should be made for

sufficient overfilling or mounding of the filled trench to compensate for subsequent

settlement.

The following guidelines apply to backfilling operations:

Note: If a compactor is used, area gas monitoring shall be conducted throughout

the compacting activity

1. All water shall be removed from the trench before backfilling commences.

2. The bottom of the trench shall be padded as far as is reasonably practicable

with a minimum of 150mm of suitable granular material, i.e., building sand, to be

approved by the Area Authority/BP representative, free from hard objects which

might damage the pipe coating. This padding shall be compacted in layers of

150mm.

Note: The removal of any fine materials from riverbanks and / or riverbeds is

strictly prohibited.

3. Before backfilling, it must be checked that the pipe is evenly bedded on the

trench padding throughout its length.

4. Imported granular or selected excavated materials, i.e., building sand, shall then

be rammed at sides (150mm) and around the pipe until 300mm of cover over

the top of the pipe has been hand rammed.

5. The original topsoil is to be replaced in the top of the trench with the same

depth as that on the working width.

6. All surplus excavated materials, rock, welding rods, waste and all unwanted

material shall be removed from the site of the works and the site left in a tidy

condition.

7. The backfill can be compacted if deemed necessary using a diesel driven plate

compacter but must not be used on the top or sides of the pipeline.

8. On completion of backfilling all fields, verges, tracks, paths, garage drives and

access roads should be permanently reinstated to a condition equivalent to that

before the commencement of the work.

9. Any damage to field drains etc must be repaired and local farmer/land owner be

invited to inspect the repair(s) prior to backfill.

Site Reinstatement

Reinstatement of the site shall be implemented in accordance with the EMS Manual

and Procedure No. EP-100.

Drainage

Any field drains that have been damaged should be repaired or replaced.

Drainage patterns should be returned to their original state (see 5.5 Drainage Patterns)

by using the same permeable materials that were excavated.

Topsoil reinstatement should take place in dry conditions to prevent permeability and

drainage characteristics from being altered through compaction.

Topography

In addition, excavated soils should be redistributed across the entire right-of-way to

restore the natural topography. Any areas outside the trench area that have been

compacted by moving vehicles should be loosened using deep-tine cultivators.

The responsible department in order to ensure that restoration is satisfactory or to

ensure that monitoring should continue should carry out a final inspection.

Documentation

The following documentation and information must be maintained and readily available:

 Risk Assessments

 Tr@ction electronic database

 Permits and Supplementary Certificates

 Equipment inspection reports

 Operator certificates

 Notices to 3^rd parties

 Notices received

 Excavation Report

5.4 WORKING ON SCAFFOLDING

All scaffolding must have:

 guard rails on all open sides: top rail 42 inches above the work platform

surface, middle rail 21 inches above the work surface.

 toe boards on all sides

 side screens on sides adjacent to passageways or thoroughfares

 scaffold boards in good condition and extending not less than six inches, nor

more than 12 inches, beyond their end supporters (unless otherwise secured

from being dislodged)

 an access ladder secured to the scaffold with minimum required clearances

between ladder rungs and away from obstacles that interfere with safe use of

the ladder.

Note: Loose articles and materials must be kept to an absolute minimum on

scaffolding platforms. All necessary precautions must be taken to prevent

objects from falling from scaffolds, e.g., by use of toe boards.

5.5 SAFE USE OF LADDERS

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

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

Note:

Ladders are potentially dangerous. The must common type of accident

occurs through a ladder slipping.

 Always place a ladder on a firm base, set the angle near to 75

 Make sure the ladder projects well above the level at which the user

stands.

 Ensure sufficient overlap between stages of extension ladders.

 Do not load ladder beyond maximum intended load.

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

guard doorways in which a ladder is placed.

 Keep area around the top and bottom of ladder clear.

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

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

 Do not stand on cross bracing.

 Always face the ladder when ascending or descending.

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

3 SCAFFOLDING DESIGN REQUIREMENTS

3.1 MATERIALS

3.1.1 All Materials

Before use, a competent person must inspect all scaffolding and material used in

construction in order to ensure:

 it is in good condition and is serviceable

Note: Damaged or deteriorated equipment shall not be used

 It is in compliance with BS 5973 & other relevant British Standard

documentation.

3.1.2 Wooden Boards

Wooden boards should be inspected to see that they are:

 graded for scaffold use

Note: Wooden boards used for scaffolding must be specifically graded

for scaffold use by a nationally recognised grading agency.

 is sound and in good condition

 straight grained, free from saw cuts, splits and holes.

 In the case of 38mm thick, are banded at either end or nail plates fitted

3.2 CONSTRUCTION

3.2.1 National Requirements

The scaffold assembly must be designed to comply with local state or United

Kingdom requirements, whichever is the higher.

Scaffolds required with a loading capacity greater than 2.5kn/m2 must always be

subject to qualified scaffold designer input / approval.

3.2.2 Load Calculations

Frame spacing and mud sill size can only be determined after the total loads to be

imposed on the scaffold and the strength of the supporting soil or structure are

calculated and considered. A qualified person prior to the scaffold structure being

built must do this analysis.

Note: Manufacturers load carrying information shall be used for design calculations

3.2.3 Construction, Dismantling and Alteration

Competent workmen under competent supervision must carry out the erection,

dismantling and alteration of scaffolding.

Plumb and level scaffold until connections can be made with ease. Do not force

members to fit. Be sure scaffold stays level and plumb as erection progresses.

During dismantling of scaffolding, tubes and fittings shall not be dropped to the

ground but always carefully lowered. Tubes shall be stacked flat and fittings collected

into bags or containers.

3.2.4 Support and Bracing

Scaffolding must be securely supported or suspended, and where necessary braced

to ensure stability. Unless constructed as freestanding independent scaffolding, it

must be rigidly connected with the building or structure (not to pipe work).

Ties, guys, bracing and/or outriggers may be needed to assure a safe stable scaffold

assembly. Determine the need for stability bracing.

If in doubt - ask.

The requirement for stability bracing is dependent upon:



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

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

or 3.5 times externally, the minimum base width dimension must

always be secured to a rigid structure or seek alternative means of

support.

Internally = no wind loading

Externally = relatively sheltered locations / minor wind loading



wind loads



the use of brackets or cantilevered platforms



imposed scaffold loads.

Ties:



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

base width and every four (4) meters vertically thereafter. Ties should be

placed as close to the top of the scaffold as possible and, in no case, more

than three (3) times the minimum base width of the scaffold from the top.



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

than 4meters horizontal intervals in between.



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

the scaffold is dismantled to that height.



Ties should be constructed to

6.25kn

(slipload) unsheeted &

12.5kn

sheeted

Guys:



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

above or otherwise restrained to prevent tipping or overturning.

Note: Circular scaffolds erected completely around or within a structure

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

members.

3.2.5

Planks

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

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

platforms in good condition.

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

be cleated / securely tied for example, 3 metre board on 2.8 meter spans

 must be cleated/securely tied.

 Board must not extend beyond the support by more than 4.5 x thickness

Such overhangs should be separated from the work platform by guard-

railing so that they cannot be walked on.

 Spans of full thickness, 50mm by 250mm scaffold grade boards, should

never exceed 2.6m. Loads on boards should be evenly distributed and not

exceed the allowable loads for the type of board being used.

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

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

prevent uplift or displacement due to high winds or other job conditions.

3.2.6

Guardrails and Toe Boards

 The scaffolds shall be supplied with the toe boards and guardrails when

the height of board location is 1,3 m and over.

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

distance between the posts of guardrails should not exceed 2.7 metres.

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

Both top and mid-rails are required. Local codes specify the minimum

heights where guardrails are required, however, use at lower heights if falls

can cause injury.

3.2.7

Transoms

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

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

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

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

3.2.8 Scaffold Access

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

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

frames with built-in ladders are used, cleated boards or fabricated boards must be

used at platform levels to minimize or eliminate platform overhang. Access ladders

must extend at least 1 metre above platforms.

3.2.9 Bridging Scaffold

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

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

fitted.

3.2.10 Mud Sills and Screw Jacks

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

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

surface.

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

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

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

3.2.11 Dismantling Scaffold

3.3 ROLLING SCAFFOLDS

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

minimum base dimension. Outrigger frames or outrigger units on both sides of the

tower may be used to increase base width dimension when necessary.

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

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

the capacity of the casters.

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

must be kept level and plumb at all times.

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

at least every alternate lift. Fabricated boards with hooks may replace the top

diagonal brace.

 All frames must be fully cross-braced.

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

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

4 INSPECTIONS AND SCAFFTAGS

4.1 SITE INSPECTION (PRE-CONSTRUCTION)

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

supporting structure, and for proximity of electric power lines, overhead obstructions,

wind conditions, the need for overhead protection or weather protection coverings.

Special care is needed when scaffolding is to be erected on fill or other soft ground or

on frozen ground. These conditions must be evaluated and suitably provided for.

4.2 SITE INSPECTION (POST-CONSTRUCTION)

A competent person shall inspect scaffolding:

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

 following any alteration

 if it has been exposed to weather conditions likely to affect its strength or

stability.

Details of inspections must be recorded & must be auditable.

4.3 SCAFFTAGS

“Scafftags” shall be used on all scaffold structures, whether complete or part

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

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

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

to be unsafe for any reason, the green scafftag must be pulled to display the red (Do

Not Use) tag.

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

5 SCAFFOLDING USE

5.1 INSPECTION

Inspect the scaffold assembly before each use. In particular, check:

 the Scafftag - Pay particular attention to the load rating

 that the scaffold is assembled correctly:

 that it is level and plumb

 base plates are in firm contact with sills

 bracing is in place and connected

 platforms are fully boarded with guardrails in place

 safe access is provided

 that the scaffold is properly tied and/or guyed

 there are no overhead obstructions or electric cables within 4 meters of the

scaffold assembly.

5.2 ACCESS

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

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

5.3 WORKING SAFELY

5.3.1 Personnel Movement on Scaffold

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

work practices shall apply:

 Climb safely. In particular, when on ladders:

 face the rungs as you climb up or down.

 use both hands on the ladder and maintain „three point‟ contact

(keep one hand firmly on frame or ladder at all times)

 do not try to carry materials while you climb

 ensure footing and balance before releasing hand grips

 do not work on / from the access ladder

 do not overload platforms with materials

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

person.

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

boxes or ladders on scaffold platforms

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

Alterations shall only be carried out by suitably qualified

/ authorised

personnel under the supervision of a qualified person.

Note: Any removed component should be immediately replaced.

5.3.2 Dropped Objects

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

platforms. All necessary precautions must be taken to prevent objects from falling

from scaffolds, e.g. by use of toe boards.

5.3.3 Cantilevered Platforms

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

been designed to support material loads.

(These types of platforms cause

overturning and uplift forces, which must be compensated for. All frames should be

fastened together to prevent uplift an overturning moment compensated for with

counterweights or adequate ties).

5.3.4 Hoisting and Lifting

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

the assembly is designed for that purpose.

5.4 ROLLING SCAFFOLDING

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

the tower while it is being moved.

 Lock all casters before getting on the tower.

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

area by reaching out over guard railing.

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

 Secure all materials before moving scaffolds.

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

scaffold.

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

path of rolling scaffold.

 Rolling towers must only be used on level surfaces.

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

top.

5.5

“QUICK ERECT” ALUMINIUM SCAFFOLDING

The use of “quick erect” aluminium scaffold systems can be used subject to local

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

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

6 LADDERS

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

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

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

occurs through a ladder slipping.

6.1 TRANSPORTING AND MOVING LADDERS

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

ground.

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

Note: Do not walk under a ladder

Tie ladders down securely when transporting.

6.2 MAINTENANCE

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

inspections shall be registered not be longer than six months.

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

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

Use" notice and withdraw the ladder from service.

6.3 PREPARATION

Inspect ladder prior to EVERY use.

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

hand and that it is in good condition

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

danger of sparks when the ladder impacts steel).

Use ladders only for the purpose for which they were designed

(refer to

manufacturer's labelling and recommendations).

6.4

SAFE USE OF LADDERS



Always place a ladder on a firm base, set the angle near to 75.



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

stands.



Ensure sufficient overlap between stages of extension ladders.



Secure the ladder in place wherever reasonably practicable.



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

ladder is in use.



Do not load ladder beyond maximum intended load.



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

guard doorways in which a ladder is placed.



Keep area around the top and bottom of ladder clear.



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



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



Do not stand on cross bracing.



Always face the ladder when ascending or descending.



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

hands/1 foot should be in contact with ladder at all times).



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

items such as tool boxes or materials.
