Describe Halon 1211 (BCF) in technical terms
Halon 1211 is a liquefied gas which, when discharged leaves the nozzle in a stream that is about 85% liquid and 15% gas. This gives it a range of about 2,5 - 4,5m.
Halon works by chemically reaction with the fires components. It stops the components of the “Fire Triangle” from working together.
It also doesn’t produce any residue which is good cause there is less secondary damage to assets and has relatively low toxicity
