11.5.1 The cargo compressor
and pump rooms of any ship should be provided with a carbon dioxide
system as specified in SOLAS regulation
II-2/10.9.1.1. A notice should be exhibited at the controls
stating that the system is only to be used for fire-extinguishing
and not for inerting purposes, due to the electrostatic ignition hazard.
The alarms referred to in SOLAS regulation
II-2/10.9.1.1.1 should be safe for use in a flammable cargo
vapour-air mixture. For the purpose of this requirement, an extinguishing
system should be provided which would be suitable for machinery spaces.
However, the amount of carbon dioxide gas carried should be sufficient
to provide a quantity of free gas equal to 45% of the gross volume
of the cargo compressor and pump-rooms in all cases.
11.5.2 Cargo compressor and
pump rooms of ships which are dedicated to the carriage of a restricted
number of cargoes should be protected by an appropriate fire-extinguishing
system approved by the Administration.
