The HFC-227ea fire suppression agent was the first non-ozone-depleting replacement for Halon 1301. [citation needed] In addition, HFC-227ea leaves no residue on valuable equipment after discharge. [2] HFC-227ea contains no chlorine or bromine atoms, presenting no ozone depletion effect. Its atmospheric lifetime is approximated between 31 and 42 ...
Halon systems are among the most effective and commonly used fire protection systems used on commercial aircraft. Halon 1301 is the primary agent used in commercial aviation engine, cargo compartments, and auxiliary power unit fire zones. [9] [10] Efforts to find a suitable replacement for Halon 1301 have not produced a widely accepted replacement.
In the 1970s, Halon 1211 came over to the United States from Europe where it had been used since the late 1940s or early 1950s. Halon 1301 had been developed by DuPont and the United States Army in 1954. Both 1211 and 1301 work by inhibiting the chain reaction of the fire, and in the case of Halon 1211, cooling class A fuels as well.
PhostrEx meets the requirements of both the Montreal Protocol and the Clean Air Act, and is the first commercially viable Federal Aviation Administration and United States Environmental Protection Agency certified halon replacement fire extinguishing agent. The EPA awarded the company with a 2007 Stratospheric Ozone Protection Award for the ...
Since the early 1990s manufacturers have successfully developed safe and effective Halon alternatives. These include DuPont's FM-200, American Pacific's Halotron, FirePro's FPC Compound, Plumis’ Automist and 3M's Novec 1230 Fire Protection Fluid. Generally, the Halon replacement agents available today fall into two broad categories, in-kind ...
The brand name "Halon" is frequently used interchangeably for BFCs. owever, not all Halons are technically BFCs (some contain chlorine also). BFCs attack the ozone layer even more aggressively than chlorofluorocarbons (CFCs), [ 2 ] and are powerful greenhouse gases , although due to shorter atmospheric lifetimes not as powerful as equivalent ...
Halotron I was originally introduced in 1992 as a replacement for Halon 1211(bromochlorodifluoromethane), a substance known for its significant ozone-depleting properties. While Halon 1211 has a global warming potential (GWP) of 2,070, [ 2 ] Halotron I's GWP is considerably lower at 77, reflecting a 96% reduction in environmental impact.
Tribromofluoromethane [1] or Halon 1103 or R 11B3 is a fully halogenated mixed halomethane or, more exactly, a bromofluorocarbon (BFC). It is a colorless to yellow liquid. It is a colorless to yellow liquid.
