It is also the primary component of the Halotron I fire-extinguishing mixture. Its ozone depletion potential is ODP = 0.012, and global warming potential is GWP = 76. HCFC-123 will eventually be phased out under the current schedule of the Montreal Protocol. It was discontinued in new HVAC equipment in 2020 in developed countries but will still ...
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.
Halon 1301 is widely used by the U.S. Military [7] and NASA in a 2-3/4 lb portable extinguisher with a sealed, disposable cylinder for quick recharging. Other agents such as CO 2 and FE-36 (HFC-236fa) wet chemical are largely replacing halon 1301 for environmental concerns. Civilian models in 2-3/4, 3, and 4 lb sizes were also made.
In other words, a fast flow extinguisher expels a higher volume of agent in less time than a standard compliance flow extinguisher. As a result, fast flow extinguishers have lower UL class A&B ratings than compliance flow extinguishers (the class B numerical rating is the approximate square feet of burning fuel a novice operator could expect to ...
Heavy-duty CO 2-powered fire extinguisher on standby at a temporary helicopter landing site. CO 2, a clean gaseous agent which displaces oxygen. Highest rating for 20 lb (9.1 kg) portable CO 2 extinguishers is 10B:C. Not intended for class A fires, as the high-pressure cloud of gas can scatter burning materials.
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br.It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [1]
Bromochloromethane or methylene bromochloride and Halon 1011 is a mixed halomethane.It is a heavy low-viscosity liquid with refractive index 1.4808.. Halon 1011 was invented for use in fire extinguishers in Germany during the mid-1940s, in an attempt to create a less toxic, more effective alternative to carbon tetrachloride.
Effective fire suppression requires introducing a concentration of the HFC-227ea agent between 6.25% and 9% depending on the hazard being suppressed. Its NOAEL for cardiac sensitization is 9%. The United States Environmental Protection Agency allows concentration of 9% volume in occupied spaces without mandated egress time, or up to 10.5% for a ...
