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. [11] [12] Bromotrifluoromethane was also used as a filling of the bubble chamber in the neutrino detector ...
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 .
Halon 1301 total flooding systems are typically used at concentrations no higher than 7% by volume in air, and can suppress many fires at 2.9% v/v. By contrast, carbon dioxide fire suppression flood systems operate from 34% concentration by volume (surface-only combustion of liquid fuels) up to 75% (dust traps).
The Oshkosh P-19R is an Aircraft Rescue and Fire Fighting (ARFF) vehicle and it was selected by the United States Marine Corps in 2013. [3] The first delivery occurred in June 2017, Initial Operating Capability (IOC) followed in February 2018, and in service the P-19R serves as a first-response vehicle in aircraft fire emergencies at military bases and expeditionary airfields.
A vehicle for hire is a vehicle providing private transport or shared transport for a fee, in which passengers are generally free to choose their points or approximate points of origin and destination, unlike public transport, and which they do not drive themselves, as in car rental and carsharing. They may be offered via a ridesharing company.
1,2-Dibromotetrafluoroethane (C 2 Br 2 F 4) is a haloalkane.It is also known under codenames R-114B2 and Halon 2402.It is a colorless liquid with a boiling point of 47.2 °C. R-114B2 is occasionally used in fire suppression systems.
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. [3]
