148 (1) In addition to any other requirements of this Part respecting the fire integrity of bulkheads and decks,
- (a) where a bulkhead separates a space described in Column I of an item of Table I to this section from a space described in any of Columns II to XI of that table, the bulkhead shall have the applicable minimum fire rating set out in Columns II to XI for the space described in Column I of that item; and
- (b) where a deck separates a space described in Column I of an item of Table II to this section from a space described in any of Columns II to XI of that table, the deck shall have the applicable minimum fire rating set out in Columns II to XI for the space described in Column I of that item.
(2) For the purposes of Tables I and II to this section, where a bulkhead or deck that is required to have a minimum ‘A’ Class fire rating is fitted with continuous ‘B’ Class linings or continuous ‘B’ Class ceilings, the Board may accept the continuous ‘B’ Class linings or continuous ‘B’ Class ceilings as contributing, in whole or in part, to the required ‘A’ Class fire rating of the bulkhead or deck.

machinery space of Category A

machinery space of Category A has the same meaning as in section 144; (local des machines de la catégorie A)

open deck

open deck includes any open deck space, any enclosed promenade that does not contain a fire risk and any space outside a superstructure or deckhouse; (pont découvert)

other machinery space

other machinery space means a machinery space as defined in section 144 but does not include a machinery space of Category A; (autre local des machines)

service space (high risk)

service space (high risk) includes any galley, pantry containing cooking appliances, paint room, lamp room, locker and store-room that has an area of 2 m or greater, and workshop, other than a workshop forming part of a machinery space; (local de service (risque élevé))

Notes

Return to footnote ^1.Bulkheads separating the wheelhouse, chartroom and radio room from each other may have a ‘B-0’ Class fire rating.
Return to footnote ^2.See sections 170 and 171 for specific requirements.
Return to footnote ^3.Bulkheads separating cargo pump rooms and machinery spaces of Category A may be penetrated by cargo pump shaft glands and similar glanded penetrations if gas-tight seals with efficient lubrication or other means of ensuring the permanence of the gas-tight seals are fitted in way of the bulkhead.
Return to footnote ^4.A bulkhead of the rating shown is only required where the adjacent space is used for a different purpose. For example, a galley adjacent to a galley does not require an ‘A-0’ Class bulkhead but a galley adjacent to a paint room requires an ‘A-0’ Class bulkhead.
Return to footnote ^*Where an asterisk appears in the table, the bulkhead shall be constructed of steel or an equivalent material but the bulkhead is not required to have an ‘A’ Class fire rating.

Return to footnote ^1.Decks separating cargo pump rooms and machinery spaces of Category A may be penetrated by cargo pump shaft glands and similar glanded penetrations if gas-tight seals with efficient lubrication or other means of ensuring the permanence of the gas-tight seals are fitted in way of the deck.
Return to footnote ^2.A deck of the rating shown is only required where the adjacent space is used for a different purpose. For example, a galley adjacent to a galley does not require an ‘A-0’ Class deck but a galley adjacent to a paint room requires an ‘A-0’ Class deck.
Return to footnote ^*Where an asterisk appears in the table, the deck shall be constructed of steel or an equivalent material but the deck is not required to have an ‘A’ Class fire rating.
