Parent topic: Part B - Fire Safety Measures for Passenger Ships

29.1.1 Self-closing type doors

 The door provided at this stairway enclosure should be of self-closing type.

29.2 Location of hazardous safety equipment, accessibility and size of corridors or lobbies for mustering of fire parties and application of regulation II-2/29.2 to lifts

  • 1 Safety equipment which may be hazardous (such as rockets) should not be accepted to be located in stairway enclosures. (See also interpretation 1 of regulations II-2/34.6 and 41-2.4.10)

  • 2 Small corridors or "lobbies" used to separate an enclosed stairway from galleys or main laundries may have direct access to the stairway and should be adequately sized to support the mustering of a fire party. In general, adequate size should be a minimum deck area of 4.5 m2 and a width of no less than 0.9 m. Such small corridors should be treated as category (3) spaces of regulation II-2/26.2.2 or category (2) spaces of regulation II-2/27.2.2 and contain a fire hose station. The spaces which open to these small corridors should have means of escape in accordance with regulation II-2/28

  • 3 Regulation II-2/29.2 does not need to be applied to lifts.

29.3 Arrangements for lift machinery rooms and lifts serving different categories of spaces

  • 1 For lifts totally within stairway enclosures, the relevant machinery should be arranged in a separate room, surrounded by steel boundaries, except that small passages for lift cables are permitted.

  • 2 Lifts which open on some decks into spaces other than corridors, public spaces, special category spaces, stairways and external areas (e.g. provision rooms, galleys, laundries, machinery spaces, etc.) can not open on other decks into stairways included in the means of escape.
