### Merchant Shipping (Safety) (Fire Protection) (Ships Built Before 25 May 1980) Regulations 《商船(安全)(防火)(1980年5月25日之前建造的船舶)規例》

57. Additional requirements for ships carrying explosives
(1) Where any ship to which these regulations apply (other than a passenger ship) carries explosives of such nature and of such quantity that had the ship been a passenger ship, the explosives would not have been permitted on such ship by Chapter 7.1 of the IMDG Code, such explosives shall not be carried in any compartment in the ship which is fitted with steam fire smothering arrangements. A fire detection system complying with regulation 68 or a smoke detection system shall be provided in any compartment containing such explosives and in every adjacent compartment. (L.N. 252 of 2018; L.N. 151 of 2022)
(2) For the purposes of this regulation “compartment” (艙室) means all spaces contained between 2 adjacent permanent bulkheads and includes the lower hold and all cargo spaces above it. The whole of any shelter deck space not sub-divided by steel bulkheads the openings in which can be closed by steel closing plates shall, for the purpose of this regulation, be considered as a single space. Where steel bulkheads with openings closed by steel closing plates are fitted, the enclosed spaces in the shelter deck shall be considered as part of the compartment or compartments below.

63. No provision.

64. Fixed pressure water spraying systems for machinery spaces
(1) Every fixed pressure water spraying system fitted in compliance with these regulations shall be provided with a pump, piping system, control valves, and spraying nozzles.
(2) The spraying nozzles of a system mentioned in subregulation (1) shall be of such a type, sufficient in number and so arranged as to ensure distribution of water spray such as will effectively extinguish oil on fire in the spaces protected thereby. Spraying nozzles shall be fitted above bilges, tank tops and other areas over which oil fuel is liable to spread and above other main fire hazards in the spaces to be protected.
(3) A water spraying system mentioned in subregulation (1) may be divided into sections and shall be controlled from distribution manifolds the valves of which shall be capable of being operated from easily accessible positions which are outside the spaces to be protected and which will not be readily cut off by an outbreak of fire.
(4) A water spraying system mentioned in subregulation (1) shall be kept charged at the designed pressure and the pump supplying the water for the system shall be automatically put into action by a pressure drop in the system.
(5) The pump of a system mentioned in subregulation (1) shall be capable of supplying water at the designed pressure simultaneously to all sections of the water spraying system in any one compartment. The pump and its controls shall be installed outside the space or spaces to be protected. The system shall be so arranged that it cannot be put out of action by a fire in the space or spaces it is designed to protect.
(6) As regards a system mentioned in subregulation (1), means shall be provided which will prevent nozzles from becoming clogged by impurities in the water or corrosion of piping, nozzles, valves and pump.
(7) A water spraying system mentioned in subregulation (1) shall include mobile sprayers ready for immediate use in the firing area of the boiler or in the vicinity of the oil-fuel unit.
(8) No part of a water spraying system mentioned in subregulation (1) shall be situated forward of the collision bulkhead in any passenger ship.
(9) Operating instructions in clear and permanent lettering shall be affixed to every water spraying system mentioned in subregulation (1) or in a position adjacent thereto.

66. Fixed foam fire extinguishing installations
(1) Subject to subregulation (2), every fixed foam fire extinguishing installation fitted in compliance with these regulations other than the deck foam system specified in regulation 67 shall be capable of discharging through fixed discharge outlets in not more than 5 minutes, a quantity of foam sufficient to cover to a depth of 150 millimetres the largest single area over which oil fuel is liable to spread. Such installation shall be capable of generating foam suitable for extinguishing oil fires and shall include means for the effective distribution of the foam through a permanent system of piping and control valves or cocks to discharge outlets and fixed sprayers directing the foam on to oil fire hazards in the protected space and which shall be capable of being operated either simultaneously or separately. Such installation shall include mobile sprayers ready for immediate use in the firing area of the boiler and in the vicinity of the oil-fuel unit.
(2) Every fixed foam fire extinguishing installation fitted to meet the requirements of regulation 49(3) for the protection of the cargo oil tanks shall be capable of distributing on the decks over such tanks through fixed discharge outlets in not more than 15 minutes a quantity of foam sufficient to cover to a depth of at least 50 millimetres the whole of the tank deck area. Such installation shall be capable of generating foam suitable for extinguishing oil fires and shall include means for the effective distribution of the foam through a permanent system of piping and control valves or cocks to discharge outlets. There shall be sufficient mobile foam sprayers capable of being connected to the installation whereby foam can be directed into any tank.

For the purpose of this subregulation, “tank deck area” (液艙甲板面積) means an area equivalent to the extreme length of the cargo tanks multiplied by the breadth of the ship.
(3) Every fixed foam fire extinguishing installation herein before referred to shall be so arranged that a fire in any of the spaces it protects will not render the controls inaccessible nor put the installation out of action.
(4) Operating instructions in clear and permanent lettering shall be affixed to every fixed foam fire extinguishing installation or in a position adjacent thereto.
