Halotron I is a fire extinguishing agent based on the raw material HCFC-123 (93%) mixed with

tetrafluoromethane Tetrafluoromethane, also known as carbon tetrafluoride or R-14, is the simplest perfluorocarbon ( C F4). As its IUPAC name indicates, tetrafluoromethane is the perfluorinated counterpart to the hydrocarbon methane. It can also be classified as a ...

Halon 1211 Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be d ...

of 1890, whereas Halotron I's GWP is 77, being a 96% reduction.

Performance

In December 2011, Halotron I was tested against "hidden fires", spurred by the effectiveness its predecessor demonstrated on an in-flight fire aboard a Delta L-1011 flight on March 17, 1991. The test was conducted at UL, and demonstrated similar effectiveness as Halon 1211, with significantly less human and global harm. Although the fire extinguishing effectiveness is similar, Halotron I requires a larger chemical volume to get the same ratings as Halon 1211.
