Fire Protection ^

Helicopter Deck -and Fuel-Dispensing Facility Area

17 (1) Subject to subsection (3), an approved foam fire-extinguishing system should be installed, sufficient to cover with foam the obstacle-free area of the helicopter deck and, as applicable, the hangar, fuel dispenser and portable helicopter-fuel tank, by means of monitors or fixed pipes with nozzles; the distance from the nozzle to the furthest extremity of the deck should not be more than 0.75 x the foam throw in still air conditions.

(2) The foam should be of either the protein type or the aqueous film-forming type and be deliverable at rates not less than 6 L and 4.1 L, respectively, of foam solution per minute for each m² to be covered sufficient foam should be available at these rates for a discharge period of not less than five minutes.

(3) For a ship operating in extremely cold temperatures and where there is a frost hazard, the location of the water piping to the foam system should be carefully considered; if necessary, a hose system from a protected space, such as a heated hangar, will be acceptable for foam discharge in lieu of deck monitors or fixed pipes with nozzles.

(4) At least two fire hydrants should be fitted immediately adjacent to the helicopter deck, each complete with hose and dual-purpose (spray/jet) nozzle, such that two water sprays will be able to reach any part of the deck and, as applicable, the hangar, fuel-dispenser and portable helicopter-fuel tank.

(5) The fire hydrants should be located on opposite sides of the area so that at least one hydrant and hose will be operable during a localized fire.

(6) Mobile or portable dry-chemical fire extinguishers, each having a suitable applicator and a total capacity of at least 45 kg, should be fitted immediately adjacent to the helicopter deck.

(7) Portable gas-type fire extinguishers, each having a suitable applicator and a total capacity of at least 18 kg Of C0₂ or its equivalent, should be fitted immediately adjacent to the helicopter deck.

(8) Where a fuel dispenser is not on the same deck as the helicopter deck, an additional portable 9 kg dry-chemical fire extinguisher or its equivalent, should be located beside the dispenser.

(9) For a ship operating in extremely low temperatures and where fire extinguishers are to be exposed to such cold conditions, the low-temperature characteristics Of CO₂ should be taken into account when this gas is considered for fire extinguishing.

Helicopter Hangar and Workshop ^

18 (1) Where fire-extinguishing equipment for the helicopter deck is immediately available, no additional equipment is necessary for the helicopter hangar.

(2) Where problems may exist in making all or some fire-extinguishing equipment of the helicopter deck immediately available for use in the helicopter hangar, fire-extinguishing equipment to be permanently located in the hangar should meet types and quantities specially determined by the Board.

(3) At least one portable 2 kg dry-chemical (multipurpose), fire extinguisher or its equivalent, should be located in the helicopter workshop.

Winching Area ^

19 (1) At least two fire hydrants should be fitted on deck immediately adjacent to the winching area, each complete with hose and dual-purpose (spray/jet) nozzle such that two water jets will be able to reach any part of the area

(2) The fire hydrants should be located on opposite sides of the area so that at least one hydrant and hose will be operable during a localised fire.

(3) During winching operations, at least two of a ship’s portable 4.5 kg dry-chemical (multipurpose) fire extinguishers, or their equivalents, should be available immediately adjacent to the winching area.

Aviation Fuel Pump Room ^

20 (1) An aviation-fuel pump room should be provided with fixed fire protection to conform with the requirements for a cargo pump room on a tanker as prescribed in the Fire Detection and Extinguishing Equipment Regulations.
