3.2.1 Tanks or tank batteries located above deck
should be shielded with class A-60 insulation towards accommodation,
service stations, cargo spaces and machinery spaces.
3.2.2 The tank room boundaries and ventilation
trunks to such spaces below the bulkhead deck should be constructed
to class A-60. However, where the room is adjacent to tanks, voids,
auxiliary machinery spaces of little or no fire risk, sanitary and
similar spaces, the insulation standard may be reduced to class A-0.
3.2.3 The fire and mechanical protection of gas
pipes lead through ro-ro spaces on open deck should be subject to
special consideration by the Administration depending on the use and
expected pressure in the pipes. Gas pipes lead through ro-ro spaces
on open deck should be provided with guards or bollards to prevent
vehicle collision damage.
3.2.4 The bunkering station should be separated
by class A-60 divisions towards other spaces, except for spaces such
as tanks, voids, auxiliary machinery spaces of little or no fire risk,
sanitary and similar spaces where the insulation standard may be reduced
to class A-0.
3.2.5 When more than one machinery space is required
and these spaces are separated by a single bulkhead, the bulkhead
should be class A-60.
3.2.6 A compressor room in a ship not subject
to the IGC Code should be regarded as a machinery
space of category A for fire insulation requirements.
