3.2.1 No accommodation or service
spaces or control stations shall be located within the cargo area
except over a cargo pump-room recess or pump-room recess that complies
with SOLAS regulations II-2/4.5.1 to
4.5.2.4 and no cargo or slop tank shall be aft of the forward
end of any accommodation.
3.2.2 In order to guard against
the danger of hazardous vapours, due consideration shall be given
to the location of air intakes and openings into accommodation, service
and machinery spaces and control stations in relation to cargo piping
and cargo vent systems.
3.2.3 Entrances, air inlets
and openings to accommodation, service and machinery spaces and control
stations shall not face the cargo area. They shall be located on the
end bulkhead not facing the cargo area and/or on the outboard side
of the superstructure or deck-house at a distance of at least 4% of
the length (L) of the ship but not less than 3 m from the end of the
superstructure or deck-house facing the cargo area. This distance,
however, need not exceed 5 m. No doors shall be permitted within the
limits mentioned above, except that doors to those spaces not having
access to accommodation and service spaces and control stations, such
as cargo control stations and store-rooms, may be fitted. Where such
doors are fitted, the boundaries of the space shall be insulated to
"A-60" standard. Bolted plates for removal of machinery may be fitted
within the limits specified above. Wheelhouse doors and wheelhouse
windows may be located within the limits specified above so long as
they are so designed that a rapid and efficient gas- and vapour-tightening
of the wheelhouse can be ensured. Windows and sidescuttles facing
the cargo area and on the sides of the superstructures and deck-houses
within the limits specified above shall be of the fixed (non-opening)
type. Such sidescuttles in the first tier on the main deck shall be
fitted with inside covers of steel or equivalent material.
