2. each cabin crew member descends an evacuation slide from a height representative of the aeroplane's main deck sill height;
3. .2 As far as practicable, the bulkheads forming the boundaries of the main vertical zones above the bulkhead deck shall be in line with watertight subdivision bulkheads situated immediately below the bulkhead deck.
4. At least one hand fire extinguisher must be located in, or readily accessible for use in, each galley not located on the main passenger deck;
5. at least one hand fire extinguisher must be located in, or readily accessible for use in, each galley not located on the main passenger deck;
6. When partial watertight bulkheads and webs are fitted on the bulkhead deck, above or in the immediate vicinity of main subdivision bulkheads, they shall have watertight shell and bulkhead deck connections so as to restrict the flow of water along the deck when the ship is in a heeled damaged condition.
7. 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.
8. .5 At least one of the means of escape required by 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 deck if the embarkation deck does not extend to the main vertical zone being considered.
9. .3 On ships constructed on or after 1 January 2003 isolating valves shall be installed for all open deck fire main branches used for purposes other than fire-fighting.
10. .9 Main vertical zones are those sections into which the hull, superstructure, and deckhouses are divided by ‘A’ class divisions, the mean length and width of which on any deck does not in general exceed 40 metres.
11. .9 Main vertical zones are those sections into which the hull, superstructure, and deckhouses are divided by “A” class divisions, the mean length and width of which on any deck does not in general exceed 40 metres.
12. .3 In ships constructed on or after 1 January 2003 isolating valves shall be installed for all open deck fire main branches used for purposes other than fire-fighting.
13. a further descent is made when the cabin crew member qualifies on an aeroplane type in which the main deck exit sill height differs significantly from any aeroplane type previously operated.
14. The length and width of main vertical zones may be extended to a maximum of 48 metres in order to bring the ends of main vertical zones to coincide with subdivision watertight bulkheads or in order to accommodate a large public space extending for the whole length of the main vertical zone provided that the total area of the main vertical zone is not greater than 1600 m2 on any deck.
15. .1 Every ship shall be provided with a self-contained emergency source of electrical power with emergency switchboard located above the bulkhead deck, in a readily accessible space which shall not be contiguous to the boundaries of machinery spaces of category A or of those spaces containing the main source of electrical power or main switchboard.
