2.9.1 All materials and equipment used in connection
with the diving system should be, as far as is reasonably practicable,
of fire-retardant type in order to minimize the risk of fire and sources
of ignition.
2.9.2 Spaces in the interior of ships or floating
structures in which the diving system or its auxiliary equipment is
carried should be provided with structural fire protection in a way
similar to control stationsfootnote bounding main
zones.
2.9.3 Interior spaces containing diving equipment
such as surface compression chambers, diving bells, gas storage, compressors
and control stands should be covered with an automatic fire detection
and alarm system and a suitable fixed fire-extinguishing system.
2.9.4 Portable fire extinguishers of approved
types and designs should be distributed throughout the space containing
the diving system. One of the portable fire-extinguishers should be
stowed near the entrance to that space.
2.9.5 When pressure vessels are situated in enclosed
spaces, a manually actuated water spray system having an application
rate of 10 1/m2/per minute of the horizontal projected
area should be provided to cool and protect such pressure vessels
in the event of external fire. When pressure vessels are situated
on open decks, fire hoses may be considered as providing the necessary
protection.
2.9.6 Each compartment in a surface compression
chamber should have a suitable means of extinguishing a fire in the
interior which would provide rapid and efficient distribution of the
extinguishing agent to any part of the chamber.
