DEFINITIONS

The following definitions apply specifically to this paragraph—

A Class divisions

means those divisions formed by bulkheads and decks that are—

• (a)constructed of steel or other equivalent material; and
• (b)suitably stiffened; and
• (c)constructed so as to be capable of preventing the passage of smoke and flame to the end of the one hour standard fire test; and
• (d)insulated with non-combustible materials, with the effect that—
  • (i)the average temperature of the unexposed side will not rise above the original temperature by more than 139°C; and
  • (ii)the temperature, at any one point, including any joint, will not rise above the original temperature by more than 180°C, within the times listed below—

    	Class “A-60”	60 min
    	Class “A-30”	30 min
    	Class “A-15”	15 min
    	Class “A-0”	0 min

accommodation spaces

means those spaces used for public spaces, corridors, lavatories, cabins, offices, hospitals, cinemas, games and hobbies rooms, hairdressers, pantries containing no cooking appliances and similar spaces;

B Class divisions

means those divisions formed by bulkheads, decks, ceilings or linings that—

• (a)are constructed so as to be capable of preventing the passage of flame to the end of the first one-half hour of the standard fire test; and
• (b)have an insulation value such that—
  • (i)the average temperature of the unexposed side will not rise more than 139°C above the original temperature; and
  • (ii)the temperature, at any one point, including any joint, will not rise more than 225°C above the original temperature, within the time listed below—

    	Class “B-15”	15 min
    	Class “B-0”	0 min; and

• (c)are constructed of non-combustible materials, including all materials used in the construction and erection of “B” class divisions, with the exception that combustible coatings veneers may be permitted by a surveyor, provided the surveyor is satisfied that the use of a combustible coating veneer does not compromise the requirements of subparagraphs 1 and 2 of the Fire Protection provisions of Part 40D;

cargo area

means that part of the ship that contains—

• (a)cargo tanks, slop tanks and cargo pump-rooms, including pump-rooms, cofferdams, ballast and void spaces adjacent to cargo tanks; and
• (b)deck areas throughout the entire length and breadth of the part of the ship over the above mentioned spaces;

cargo spaces

are all spaces used for cargo (including cargo oil tanks) and trunks to such spaces;

control stations

are those spaces in which the ship’s radio or main navigation equipment or the emergency source of power is located, or where the fire recording or fire control equipment is centralised;

fire appliance

means any device, arrangement, apparatus or thing intended to provide protection against fire;

machinery spaces

means those machinery spaces of Category A and all other spaces containing propulsion machinery, boilers, fuel oil units, steam and internal combustion engines, generators, steering gear, major electrical machinery, oil filling stations, refrigerating, stabilising, ventilating and air conditioning machinery and similar spaces, and trunks to such spaces;

machinery spaces of Category A

means those spaces and trunks to such spaces that contain—

• (a)internal combustion machinery used for main propulsion; or
• (b)internal combustion machinery used for purposes other than main propulsion where such machinery has in the aggregate total power output of not less than 375 kW; or
• (c)any oil-fired boiler or oil fuel unit;

open ro-ro cargo spaces

mean ro-ro cargo spaces either open at both ends, or open at one end and provided with adequate natural ventilation effective over their entire length through permanent openings in the side plating or deck head to the satisfaction of the Chief Executive Officer or a surveyor;

passenger space

means space provided for the use of passengers;

ro-ro cargo spaces

mean spaces not normally subdivided in any way and extending to either a substantial length or the entire length of the ship in which goods (packaged or in bulk, in or on rail or road cars, vehicles (including road or rail tankers), trailers, containers, pallets, demountable tanks or in or on similar stowage units or other receptacles) can be loaded and unloaded normally in a horizontal direction;

service spaces

are those spaces used for galleys, pantries containing cooking appliances, lockers and store-rooms, workshops other than those forming part of the machinery spaces, and similar spaces and trunks to such spaces; and

special category A spaces

mean those enclosed spaces above or below the bulkhead deck intended for the carriage of motor vehicles with fuel in their tanks for their own propulsion, into and from which such vehicles can be driven and to which passengers have access.
