Halon an extinguishing agent was developed after World War II for the
protection of aircraft engines. Several types were developed, and several
were banned and discontinued such as halon 104. Other types were halon
1202, halon 1211, halon 1301, and halon 2402, which was never widely used
in the United States due to its high toxicological concerns. Halon type 1101
was widely utilized for aircraft engines. The two most common types being;
halon 1301 bromotrifluoromethane, CBrF3, which is most commonly used in
fixed system, and halon 1211 bromochlorodifluoromethane, CBrClF2, which
is used in portable systems. Halons are synthetic gases, grouped under the
category of halogenated hydrocarbons, that exhibit exceptional fire-fighting
and explosion prevention/suppression effectiveness when appropriately
applied. Halon chemically interferes with the combustion process of fire
resulting in extinguishment. Halon is stored as a liquid, which then vaporizes
into a gas. Its boiling......
