- A compound in which the hydrogen atoms of a hydrocarbon have been replaced by bromine and other halogen atoms; very stable; used in fire extinguishers although it is thought to release bromine that depletes the ozone layer
- (Halons) The haloalkanes (also known as halogenoalkanes or alkyl halides) are a group of chemical compounds derived from alkanes containing one or more halogens. They are a subset of the general class of halocarbons, although the distinction is not often made. ...
- (halons) chemical compounds developed from hydrocarbons by replacing atoms of hydrogen with atoms of halogens, such as fluorine, chlorine or bromine. CFCs are halons (see above). Halons are widely used as fire extinguishing agents.
- (Halons) These man-made substances (also known as bromofluorocarbons) are chlorofluorocarbons that contain bromine. See also Chlorofluorocarbons and Related Compounds.
- A gas used to extinguish fires effective only in closed areas.
- Bromine-containing compounds with long atmospheric lifetimes whose breakdown in the stratosphere causes depletion of ozone. Halons are used in firefighting.
- Chemical gas fire extinguishing or liquid agent for diminishing the combustion reaction rate by acting as a thermal ballast; used mainly in closed computer rooms, aircraft, and other high-value installations where corrosive chemicals or water extinguishers are judged inappropriate. ...
- A very stable and unreactive chemical commonly used in fire extinguishment.
- A series of ionized hydrocarbon gases and liquids (halogenated hydrocarbons) that have the ability to halt chemical reactions and thus extinguish fires rapidly.
