Category: About Halon
While the production of Halon ceased on January 1, 1994 under the Clean Air Act, it is still legal to purchase and use recycled Halon and Halon fire extinguishers. In fact, the FAA requires all commercial aircraft to exclusively use halon.
The FAA accepts hand held extinguishers approved by Underwriters Laboratories. For occupied spaces on aircraft, halon 1211 extinguishers should have a minimum fire rating of 5BC and contain not less than 2.5# of halon. Halon agents include halon 1211/1301 blends approved for use.
