Voorbeeldzinnen

1. .15 Fire detection systems with a zone address identification capability shall be so arranged that:
2. wetted zone stops the fire for at least 4 minutes and
3. There shall not be more than fifty enclosed spaces in one fire detection zone.
4. In order to avoid delays in detecting the origin of the fire, the number of enclosed spaces included in each fire detection zone shall be limited.
5. On passenger vessels which do not have a fire detection system with remote identification of individual fire detectors, a fire detection zone shall not comprise more than the area constituted in accordance with Article 15.11(10).
6. The activation of a fire detector in an individual cabin in this fire detection zone shall set off a visual and acoustic signal in the passageway outside that cabin.
7. .3.1 Hinged fire doors in stairway enclosures, main vertical zone bulkheads and galley boundaries which are normally kept open shall be self-closing and be capable of release from a central control station and from a position at the door.
8. .4a Fire doors in main vertical zone bulkheads, galley boundaries and stairway enclosures other than power-operated watertight doors and those which are normally locked, shall satisfy the following requirements:
9. In ships fitted with individually identifiable fire detectors, a section may serve spaces on both sides of the ship and on several decks but may not be situated in more than one main vertical zone.
10. .5 All fire doors in stairway enclosures, main vertical zone bulkheads and galley boundaries which are normally kept open shall be capable of release from a central control station and from a position at the door.
11. .3.2 A panel shall be placed in a continuously manned central control station to indicate whether the fire doors in stairway enclosures, main vertical zone bulkheads and galley boundaries are closed.
12. .4 In determining the applicable fire integrity standard of a boundary between two spaces within a main vertical zone or horizontal zone which is protected by an automatic sprinkler system complying with the provisions of Regulation II-2/A/8 or between such zones both of which are so protected, the lesser of the two values given in the tables shall apply.
13. .1 In ships carrying not more than 36 passengers and in ships with a length of less than 24 metres there shall be installed throughout each separate zone, whether vertical or horizontal, in all accommodation and service spaces and in control stations, except spaces which afford no substantial fire risk such as void spaces, sanitary spaces, etc., either:
14. Ventilation ducts passing through a main fire zone division without serving spaces on both sides or passing through a stairway enclosure without serving that enclosure need not be fitted with dampers provided that the ducts are constructed and insulated to “A-60” standard and have no openings within the stairway enclosure or in the trunk on the side which is not directly served.
15. At least one of the means of escape required in the paragraphs .1.1 and .1.2 shall consist of a readily accessible enclosed stairway, which shall provide continuous fire shelter from the level of its origin to the appropriate lifeboat and life-raft embarkation decks or to the uppermost weather deck if the embarkation deck does not extend to the main vertical zone being considered.
