FIRE detection AND EXTINCTION.

 promptly detected.

 means. On vessels of less than 4,000 tons there shall be two, and on larger vessels three of 

 these pumps. The pumps shall be capable of delivering a sufficient quantity of water in two 

 powerful jets simultaneously in any given part of the vessel, and shall be available for im- 

 mediate use before the vessel leaves port.

 directed on any given part of a deck occupied by passengers and crew, when the watertight

 hose can be easily coupled to them.

 supply of steam may be conveyed to every space filled with cargo. Provision for the supply 

 of steam need not be required in vessels of less than 1,000 tons.

 type referred to above. A Government which accepts a new type of extinguisher shall send 

 a description of the apparatus and particulars of the trial to the Governments of the other 

 Contracting Parties.
