Is halon a hazardous material?
Inhalation: Halon 1211 is a simple asphyxiate. Hazardous Combustion Products: Under certain conditions, fluorocarbon vapors may decompose on contact with flames or hot surfaces, creating the potential hazard of inhalation of toxic decompostion products such as hydrogen bromide, hydrogen fluoride, and hydrogen chloride.
What causes Class D fires?
Most class D fires occur when the combustible metals are in dust, flake, shaving forms or molten. A class D fire cannot be extinguished by water as it produces hydrogen at high temperatures and eventually an explosion occurs and spreads of fire further. Sands are also effective in putting out a class D fire.
How does Halon work on a fire?
Halons are electrically non-conducting and have been acknowledged as the most effective universal extinguishing agent for aircraft use. They work mainly by chemically interrupting the reaction described as the ‘Fire Triangle’ (Fuel-Oxygen-Heat) which must be sustained for a fire to continue.

Why do Halon fire extinguishers contain nitrogen?
HALON 1211 is a liquefied gas, pressurized with nitrogen, which discharges as a vapor causing no cold or static shock and no impairment of the operator’s vision. This “CLEAN” agent quickly penetrates difficult-to-see and hard-to-reach areas and leaves no residue. It is recommended for protection of delicate, sensitive, and expensive computers, electrical equipment, tapes and film
When did Halon fire extinguishers become illegal?
The production of Halon has been banned in most countries since 1994 as per the Montreal Protocol. Since then the remaining supplies in extinguishers are being recycled, and can be used to refill new extinguishers.
