7.1.1 The following basic principles underlie
the provisions in this chapter and are embodied therein as appropriate,
having regard to the category of craft and the potential fire hazard
involved:
-
.1 maintenance of the main functions and safety
systems of the craft, including propulsion and control, fire-detection,
alarms and extinguishing capability of unaffected spaces, after firein
any one compartment on board;
-
.2 division of the public spaces for category
B craft, in such a way that the occupants of any compartment can escape
to an alternative safe area or compartment in case of fire;
-
.3 subdivision of the craft by fire-resisting
boundaries;
-
.4 restricted use of combustible materials and
materials generating smoke and toxic gases in a fire;
-
.5 detection, containment and extinction of any
fire in the space of origin;
-
.6 protection of means of escape and access for
fire fighting; and
-
.7 immediate availability of fire-extinguishing
appliances.
7.1.2 The requirements in this chapter are based
on the following conditions:
-
.1 Where a fire is detected, the crew immediately
puts into action the fire-fighting procedures, informs the base port
of the accident and prepares for the escape of passengers to alternative
safe area or compartment, or, if necessary, for the evacuation of
passengers.
-
.2 The use of fuel with a flashpoint below 43°C
is not recommended. However, fuel with a lower flashpoint, but not
lower than 35°C, may be used in gas turbines only subject to compliance
with the provisions specified in 7.5.1 to
7.5.6.
-
.3 The repair and maintenance of the craft is
carried out in accordance with the requirements given in chapters 18 and 19.
-
.4 Enclosed spaces having reduced lighting, such
as cinemas, discothèques, and similar spaces, are not permitted.
-
.5 Passenger access to special category spaces
and open ro-ro spaces is prohibited during the voyage except when
accompanied by a crew member responsible for fire safety. Only authorised
crew members shall be permitted to enter cargo spaces at sea.
