Fire Extinguisher 30
Fire Extinguisher 30 : Clean agents and carbon dioxide: Halon (including Halon 1211 and Halon 1301): A gaseous agent that inhibits the chemical reaction of the fire. Classes B: C for lower weight fire extinguishers (2. 3 kg; under 9 lbs) and A: B: C for heavier weights (4. 1-7. 7 kg; 9-17 lbs). Banned from new production, except for military use, as of January 1, 1994 as its properties contribute to ozone depletion and long atmospheric lifetime, usually 400 years. Halon was completely banned in Europe resulting in stockpiles being sent to the United States for reuse. Although production has been banned, the reuse is still permitted. Halon 1301 and 1211 are being replaced with new halocarbon agents which have no ozone depletion properties and low atmospheric lifetimes, but are less effective
