Hull Construction Regulations

54 (1) In every ship in which Method I or Method III of fire protection has been adopted, a fire alarm and fire detection system complying with section 57 shall be installed which will detect the presence of fire in any accommodation space or service space and will indicate the presence and position of the fire by a signal given at one or more points in the ship so as to come rapidly to the notice of the master and crew of the ship.

(2) The Board may exempt any ship from the requirements of this section to the extent that it is satisfied that the accommodation spaces and service spaces afford no substantial fire risk.
