ABS规范，没强制规定，不过从经验来看，我们所有船都装有CO2室风机

3.1.9 Storage of Medium Containers (1 July 2002)
i) Except as otherwise permitted, pressure containers required for the storage of fire
extinguishing medium, other than steam, are to be located outside the protected spaces.
When the fire-extinguishing medium is stored outside a protected space, it is to be stored
in a room, which is located behind the forward collision bulkhead, and is used for no
other purposes. Any entrance to such a storage room is to preferably be from the open
deck and is to be independent of the protected space. If the storage space is located below
deck, it is to be located no more than one deck below the open deck and is to be directly
accessible by a stairway or ladder from the open deck. Spaces which are located below
deck or spaces where access from the open deck is not provided are to be fitted with a
mechanical ventilation system designed to take exhaust air from the bottom of the space,
and is to be sized to provide at least 6 air changes per hour. Access doors are to open
outwards, and bulkheads and decks including doors and other means of closing any
opening therein which form the boundaries between such rooms and adjoining enclosed
spaces are to be gastight. The boundaries of the room is to have fire-rated integrity
equivalent to that of a control station (see Section 3-4-1). The ventilation for the
storeroom is to be independent of all other spaces.
ii) (1 July 2007) Fire-extinguishing media protecting the cargo holds (see 4-7-2/7.1.1) may
be stored in a room located forward of the cargo holds, but aft of the collision bulkhead,
provided that both the local manual release mechanism and remote control(s) for the release
of the media are fitted, and the latter is of robust construction or so protected as to remain
operable in case of fire in the protected spaces. The remote controls are to be placed in the
accommodation area in order to facilitate their ready accessibility by the crew. The
capability to release different quantities of fire-extinguishing media into different cargo
holds so protected is to be included in the remote release arrangement. |
