U.S. FAA Approval for Airport Firefighting
Following the 1993-1994 test program, Halotron I was approved for use in airport ramp firefighting by FAA CertAlert 95–03 (a copy of this CertAlert is available upon request) as a replacement for halon 1211 (BCF). The primary application for Halotron I at commercial airports has been in aircraft rescue and firefighting (ARFF) vehicles. Halotron I is in use in 150 lb to 500 lb (68 to 227 kg) fire equipment systems at more than 80 U.S. and international airports. Multiple manufacturers, includingOshkosh Truck andE One, offer ARFF vehicles that incorporate high performance Halotron I systems with 50 ft (15 m) to 150 ft (46 m) hand lines.

U.S. FAA Approval for Onboard Aircraft Use
One Halotron I portable extinguisher is approved by the FAA and Underwriters Laboratories, Inc. (UL) for onboard aircraft use. This is in compliance with DOT/FAA/AR-01/37, Development of a Minimum Performance Standard for Hand-Held Fire Extinguishers as a Replacement for Halon 1211 on Civilian Transport Category Aircraft. This standard specifies a minimum 5-B:C UL rating or equivalent, passing the seat fire toxicity test and passing the hidden fire test (measuring total flooding capability). The FAA onboard approval is based on a combination of agent and hardware. Currently, the Amerex model B394TS is the only approved Halotron I containing hardware for this application.
