Global emission concernsEdit

It was originally introduced in 1992 to replace the severely ozone-depleting Halon 1211 (bromochlorodifluoromethane). Halon 1211 also has a global warming potential of 1890, whereas Halotron I's GWP is 77, being a 96% reduction.[2]

PerformanceEdit

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]

DOT classificationEdit
