Just like Halon 1211, Halotron® 1 (HCFC Blend B) expels as a rapidly evaporating liquid and leaves no residue. Model B385TS effectively extinguishes Class B and C fires by cooling and smothering and it will not conduct electricity back to the operator. Recommended for a 1-6 person aircraft, including the pilot. Halotron® 1 is the most widely tested and accepted Halon 1211-alternative agent for streaming applications. Do not use in confined spaces less than 350 ft3.
