Английская Википедия:Halotron I
Шаблон:Chembox Halotron I is a fire extinguishing agent based on the raw material HCFC-123 (93%) mixed with tetrafluoromethane and argon as propellants.
Global emission concerns
It was originally introduced in 1992 to replace the severely ozone-depleting Halon 1211 (bromochlorodifluoromethane). Halon 1211 has a global warming potential of 2,070,[1] whereas Halotron I's GWP is 77, a 96 percent reduction.[2]
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.[3] Although the fire extinguishing effectiveness is similar, Halotron I requires a larger chemical volume to get the same ratings as Halon 1211.
