10.8.7 Stowage
Breathing apparatus should be stowed fully assembled in a place where it
is readily accessible. Air bottles should be fully charged and the adjusting
straps kept slack. Units should be sited so as to be available for
emergencies in different parts of the ship.

10.8.8 Training

Practical demonstrations and training in the use of breathing apparatus
should be carried out to give personnel experience in its use. Only trained
personnel should use self-contained and air line breathing apparatus,
since incorrect or inefficient use can endanger the user’s life.

if disturbed or heated, could give off toxic or flammable gases. Effective
ventilation should be maintained and, where practicable, directed towards
the work area.

10.9.2 Opening Equipment and Fittings

Whenever cargo pumps, pipelines, valves or heating coils are to be

which could be a source of further flammable or toxic gas. Whenever
such equipment is to be opened, the safe management procedure should
identify the minimum safe working practices to be adopted, including any
requirement for additional gas tests.

10.9.3 Use of Tools
Tools should not be carried into enclosed spaces, but should be lowered
in a plastic bucket or canvas bag to avoid the possibility of their being
dropped. Before any hammering or chipping is undertaken, or any power
tool is used, the Responsible Officer should be satisfied that there is no
