1.0 Purpose/Scope

The purpose of this document is to outline responsibilities and provide guidance on the

provision, control and use of breathing apparatus (BA), on KOC facilities.These guidelines describe the principal precautions that should be taken by all personneland apply to all KOC facilities.

2.0 Definitions

Breathing Apparatus (BA)

This includes self-contained sets for use by emergency response teams, airline sets, andself-rescue saver sets.

BA Wearer

Any personnel on KOC facilities who has cause to use BA equipment.

3.0 General Requirements

• KOC HSEMS Element HSE-05-4

4.0 Key Responsibilities

TL Safety/Asset HSE Team

• Ensuring that adequate BA sets are available at suitable locations aroundthe facilities and that all such locations are clearly identified on the Fire andEmergency Equipment Plans which are prominently displayed throughout thesite.





Operations/Maintenance Team Leader

• Ensuring that Operational/Maintenance staff are suitably trained with the various BAequipment they may have to use during emergency and normal operations and carryout regular training exercises in the use of BA equipment.

Operations Supervisor

• Ensuring that BA equipment used during training is serviced, cleaned andreturned to its designated location on completion of training.

• Ensuring that BA test & inspection records are maintained.

• Ensure that the pressure in BA cylinder must not be less than 80 % (i.e.240 Bar) at any time.

Maintenance Team Leader

• Ensuring that all maintenance and BA equipment checks are carried out in

Accordance with approved maintenance schedules.

• Ensuring that BA test and inspection records are maintained.

BA Wearer

• Ensuring that the BA set is in good working condition prior to use.

• Informing the Fire Team staff of any malfunctions or damage that is found,prior to and during use of BA equipment.

Specialist Vendors

In the event that BA equipment is brought onto a KOC facility by a specialist vendor then thevendor will be responsible for ensuring that the equipment is:

• In accordance with KOC specifications for use on KOC facilities.

• Fully certified.

• Fully functional and fit for the purpose for which it is to be used.

• Ensure adequate spare parts are available when requested.

• To inform of any changes or modifications to the system.





5.0 Procedure

General

5.1 General

The atmosphere in certain areas on a facility may, at times, present a hazard to the health ofpersonnel, by the generation of toxic or unpleasant gas, fumes, smoke, dust etc. Wheresuch an atmosphere occurs, if possible the source of the hazardous or toxic substanceshould be removed or rendered inert and the area subjected to forced ventilation.

The atmosphere in the area must then be tested before personnel are allowed to enter toensure that the air is free from hazardous or toxic substances and that the atmosphere issafe for breathing. Where this is not possible or air quality cannot be guaranteed, e.g. in anemergency situation, or where generation of gas or fumes may occur instantaneously andwithout warning, approved breathing apparatus (BA) must be worn.

BA equipment must comply with British Standards.

5.2 Breathing Apparatus (BA) Wearer

The BA Wearer must have a good working knowledge of the different types, duration andapplication of BA sets available, these include:

• Self contained rescue sets for emergency response team and rescue use(Maximum duration when full approx. 35 minutes).

• Airline sets supplied from a bank of BA cylinders located outside the area. TheseShould have a short duration backup cylinder incorporated into the apparatus foruse in planned vessel or confined spaces entry work.

• Self-rescue saver sets (which have a limited duration of approximately 10Minutes) for emergency evacuation use only.

All BA wearers must be appropriately trained in the use of BA, and be fully conversant withBA procedures, which must include, but not be limited to , the following:

• Minimum of two men present when using BA (Other than self-rescue saver sets).

• Standby men with standby BA sets present.

• BA control procedure established with a nominated BA controller.

5.3 Airline Breathing Apparatus

Airline BA has its own independent air supply normally from a bank of compressed BAcylinders located outside the area to be entered or a BA compressor. When this type of BAis being used the short duration backup cylinder for emergency evacuation must be fullyoperational.

In exceptional circumstances it is possible to use the facilities air system for airline BA butthis is only permissible provided that:





• An in-line air filtration unit and moisture trap, suitable for use with breathingair, is installed between the facilities air ‘take-off and the airline BA.

• The filtration unit is purposely made to provide breathing quality air and must beused in accordance with the manufacturers instructions.

• The facilities air supply to the air filtration unit and moisture trap is locked open andsuitably tagged.

• A short duration (minimum 10 minutes) back up cylinder is worn by the BA user.

5.4 Re-Charging BA cylinders

• RE-charging of BA cylinders should only be undertaken by authorized competentpersons using a BA compressor.

• Whilst re-charging BA cylinders the BA compressor should be located in an area

free from contaminants, e.g. hydrocarbon vapours, exhaust gases etc.

• The compressor should be operated, maintained and the filter elements replacedin accordance with manufacturer’s instructions and planned maintenance routines.

• Periodic checks should be made of the output air quality of the compressor. Thefrequency of these checks depends on the amount of use of the compressor but itshould be not less than every 3 months and after each filter change.

• The maximum levels of contaminant which are acceptable in air used for BA are:

- Carbon monoxide = 10 ppm or less (2.7 mg/m³)

- Carbon dioxide = 1,000 ppm (900 mg/m³)- Oil Mist = 5 mg/m³- Odor Should not have a pronounced odor- Water Water is not acceptable at all. However, moisture

content does not exceed a dew point of minus 50 FAt 1 atmosphere pressure. This requirement isIntended to prevent respirator valves from freezing andCould cause blockages in the flow of breathing air.

Above are Grade D Air Quality Specifications as specified by the American NationalStandards Institute (ANSI)

•

BA sets and spare rubber and neoprene components for BA equipment should notbe stored in the same enclosure as an air compressor due to the potential presenceof airborne contaminants, (e.g. oil mist, exhaust gases, ozone) which may cause thematerials to deteriorate.

5.5 Fit Testing

• Personnel with facial hair can sometimes have difficulty getting a seal when wearingBreathing Apparatus. It is important that you have been trained in the use of BA





before attempting to wear it and that the training includes “Fit Testing” to ensure thatthe person can get a good seal.
