### Merchant Shipping (Safety) (Fire Protection) (Ships Built On or After 1 September 1984) Regulations 《商船(安全)(防火)(1984年9月1日或之後建造的船舶)規例》

50A. Inerting, ventilation and gas measurement
(1) This regulation shall apply to oil tankers which are post October 1994 ships.
(2) Double hull and double bottom spaces shall be fitted with suitable connections for the supply of air.
(3) On tankers required to be fitted with inert gas systems—
(a) double hull spaces shall be fitted with suitable connections for the supply of inert gas;
(b) where such spaces are connected to a permanently fitted inert gas distribution system, means shall be provided to prevent hydrocarbon gases from the cargo tanks entering the double hull spaces through the system;
(c) where such spaces are not permanently connected to an inert gas distribution system, appropriate means shall be provided to allow connection to the inert gas main;
(d) suitable portable instruments for measuring oxygen and flammable vapour concentration shall be provided. In selecting these instruments, due attention shall be given for their use in combination with the fixed gas sampling line systems referred to in paragraph (e);
(e) where atmosphere in double hull spaces cannot be reliably measured using flexible gas sampling hoses, such spaces shall be fitted with permanent gas sampling lines. The configuration of such line systems shall be adapted to the design of such spaces;
(f) the materials of construction and the dimensions of gas sampling lines shall be such as to prevent restriction. Where plastic materials are used, they should be electrically conductive.
(L.N. 410 of 1995)

51. Cargo pump rooms
(1) Except as otherwise provided in subregulation (2), in every tanker of Class VII(T) of 500 tons or over, each cargo pump room and each pump room having a similar hazard shall be provided with at least one of the fixed fire extinguishing systems required by regulation 33(1) and which shall be operated from a readily accessible position outside the pump room, provided that where the fixed extinguishing system is a gas system—
(a) the alarms referred to in Schedule 10 shall be safe for use in a flammable cargo vapour/air mixture;
(b) a notice shall be exhibited at the controls stating that due to the electrostatic ignition hazard, the system is to be used only for fire extinguishing and not for inerting purposes;
(c) where the extinguishing medium used in the cargo pump room system is also used in systems serving other spaces, the quantity of medium provided or its delivery rate need not be more than the maximum required for the largest compartment.
(2) In chemical tankers, where the fixed fire extinguishing system referred to in subregulation (1) is a gas system, the concentration shall be as specified in the Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk. (L.N. 410 of 1995)
