to undertake the work.
Two air supplies should be available to the wearer of breathing apparatus, except in the case of emergency, or where this is impractical because movement in the space would be seriously impeded. A continuous supply provided from outside the space should be used. Should it prove necessary to change over to the self-contained supply, the person should immediately vacate the space.
Precautions should be taken to safeguard the continuity of the outside source of air during occupation of the space by the wearer of breathing apparatus. Special attention should be given to supplies originating from the engine-room.
A single air supply may be acceptable, where remote testing of the space is not reasonably practicable, provided prolonged presence in the space is not required and the person is situated so that he or she can be hauled out immediately in case of emergency.
A rescue harness should be worn and lifelines should be used where practicable.
Portable lights and other electrical equipment should be of a type approved for use in a flammable atmosphere.
If the person becomes unwell, an immediate check should be made that the air supply to ensure it is being maintained at the correct pressure.

7.7              Breathing apparatus and resuscitation equipment
Only self-contained breathing apparatus, specifically designed for confined space entry should be used.
Before entry, the responsible person and competent person should undertake the full pre-wearing check and donning procedures recommended by the manufacturer. In particular the following should be checked:
       sufficient clean air is at the correct pressure;
       low pressure alarms are working properly;
       the face mask fits correctly against the wearer's face, so that, there will not be an ingress of oxygen-deficient air or toxic vapours when the user inhales. It should be noted that facial hair or spectacles will prevent the formation of an airtight seal between a person's face and the face mask;
       the wearer of the breathing apparatus is aware of the emergency procedures;
       when work is being undertaken in the space, the wearer should keep the self-contained supply ready for use in case there is a failure of the continuous supply from outside the space.
When in the confined space, the breathing apparatus should not be removed and shared with others unless it is necessary to save a person's life.

7.8              Maintenance of equipment and training
The operator must ensure that all equipment used in connection with entry to or work in a confined space or during an emergency or rescue response is appropriately maintained and periodically inspected for correct operation. A maintenance record must be kept.
Equipment for testing the atmosphere of dangerous spaces must be regularly serviced and calibrated.
