Detailed explanation-1: -Halon 1301 (Bromotrifluoromethane) is the most effective fire extinguishing agent, but because of its high ozone depleting potential, the production of Halon 1301 was banned in 1994 as part of the Montreal Protocol. Since then we have specialized in safely and effectively reclaiming Halon 1301 for critical users.
Detailed explanation-2: -Halon is rated for class “B” (flammable liquids) and “C” (electrical fires), but it is also effective on class “A” (common combustibles) fires. Halon 1211 and Halon 1301 are low-toxicity, chemically stable compounds that, as long as they remain contained in cylinders, are easily recyclable.
Detailed explanation-3: -Halon-1301 is used in flooding systems for fire and explosive containment. Halon-2402 is used as a fire extinguishing agent in Japan, Russia, China, and the former states of the Soviet Union.
Detailed explanation-4: -Halons are fire extinguishing agents which are gaseous when discharged in the aircraft environment. Halons have, until recently, been in almost universal use in aircraft fire extinguishers, both portable and fixed.
Detailed explanation-5: -Halon 1301 is the optimum fire extinguishing agent for the aircraft industry. Almost every aircraft produced in the last thirty years has used Halon 1301 for engine fire protection and in many cases cargo and dry bay protection as well. Every organization associated with aviation is searching for a substitute agent.
