Section 3 Additional Requirements for High Speed Passenger Craft

301. Arrangement

1. For category B craft, the public spaces are to be divided into zones according to the following.

【See Guidance】

(1) The craft is to be divided into at least two zones. The mean length of each zone is not to ex- ceed 40 m .

(2) For the occupants of each zone there is to be an alternative safe area to which it is possible to escape in case of fire. The alternative safe area is to be separated from other passenger zones by smoke-tight divisions of non-combustible materials or fire-restricting materials extending from deck to deck. The alternative safe area can be another passenger zone provided the additional number of passengers may be accommodated in an emergency.

(3) The alternative safe area is to, as far as practicable, be located adjacent to the passenger zone it is intended to serve. There are to be at least two exits from each passenger zone, located as far away from each other as possible, leading to the alternative safe area. Escape routes are to be provided to enable all passengers and crew to be safely evacuated from the alternative safe area.

2. Category A craft need not be divided into zones.

3. Control stations, life-saving appliance stowage positions, escape routes and places of embarkation in- to survival craft are not, as far as practicable, to be located adjacent to any major or moderate fire hazard areas.

302. Ventilation

The ventilation fans of each zone in the accommodation spaces are also to be capable of being in- dependently controlled from a continuously manned control station.
