7.6.1 Each special category space should be fitted
to the satisfaction of the Administration with one of the following
fire extinguishing systems, taking into account the size of the space
and the number of vehicles carried:
-
(a) an approved fixed water-spraying system for
manual or automatic operation, to protect all parts of the space;
-
(b) an approved fixed gas fire extinguishing system
effective in dealing with petrol fuel;
-
(c) an approved system for providing high expansion
foam in effective quantities to protect all parts of the space;
-
(d) semi-portable fire extinguishers readily available
for use in the space, but with a minimum of two such extinguishers
to each such space.
Systems required under sub-paragraphs (a), (b) and (c) of this
paragraph should be controlled from outside the space.
7.6.2 Equipment which may constitute a source
of ignition of flammable vapours, and in particular electrical equipment
and wiring in such spaces, should be installed at least 0.45 metre
above the deck.
7.6.3 Special category spaces should be structurally
separated from the operating compartment, passenger accommodation
and evacuation routes as effectively as practicable. If the Administration
permits the adjacent arrangement of these spaces, provision should
be made for easy evacuation from the passenger accommodation in the
direction opposite to the special category space.
