Part of Speech: Noun
Definition: A group of chemicals containing bromine, chlorine, or fluorine, used in fire extinguishers and fire suppression systems.
Pronunciations: US: /ˈheɪlɑn/; UK: /ˈheɪlɒn/
Origin and Usage: Halons were first developed in the 1960s as a replacement for other chemicals that were harmful to the environment. They were widely used in fire suppression systems, particularly in aircraft, until it was discovered that they were contributing to the depletion of the ozone layer. As a result, the production of halons was phased out in most countries in the 1990s, and they are now largely obsolete.
