Halon System for Extinguishing Machinery Space Fire On Cargo Ships
Fire protection on ships is provided by detection and fire-fighting equipment together with structural features which are intended to contain an outbreak of fire and the employment when required of non-combustible materials to prevent its spread.
Halon 1301 (BTM) and Halon 1211 (BCF) are two halogenated hydrocarbon gases with special fire extinguishing properties. Unlike other extinguishing agents which cool the fire or displace oxygen the Halon gases inhibit the actual flame reaction. As a result of its low vapour pressure when liquefied Halon can be stored in low-pressure containers. Alternatively if a standard carbon dioxide cylinder is used then approximately three times as much gas can be stored. An additional advantage is that the atmosphere in a Halon flooded space is not toxic, although some highly irritant gases are produced in the extinguishing process.
