Halon fire extinguisher
The Halon fire extinguishers contain Halon 1211
which can be used against all types of fires.
Halon 1211 is a liquid chemical which, when ex-
pelled from the nozzle, contains approx. 85% liquid
and 15% gas. The liquid, when hitting the fire, forms
a cloud. The extinguishing effect is obtained
through a chemical reaction in the flames. The
extinguishant leaves no residue and is considered
non
−
toxic; however, there may be a slight ”narcotic”
effect.
Halon fire extinguisher operation:
−
Hold extinguisher upright.
−
Release safety catch.
−
At a distance of 1
−
2 m (3
−
7 feet), aim at base of
flames and depress trigger fully.
Only the fully developed cloud of extinguishant is
most effective, not the stream immediately ejected
from the nozzle outlet. If the cloud does not develop
around base of flames, move further back.
When extinguishing liquid fires, never aim full
stream into liquid.
When fighting fires in solid combustibles, apply
extinguishant shot

wise.
