CO2 extinguisher
(gcide) | CO2 extinguisher \CO2 extinguisher\ (s[=e]"[-o]*t[=oo]`
[e^]ks*t[i^][ng]"gw[i^]sh*[~e]r),
a device for suppressing fire, consisting of a steel cylinder
containing compressed carbon dioxide, which may be released
by pressing on a handle. The release of the gas is usually
accomplished through a hose attached to a funnel-shaped vent
which is directed at the base of the fire, and when released,
part of the carbon dioxide is chilled sufficiently to
solidify into a powder. The large quantity of inert carbon
dioxide released on top of a small fire is usually sufficient
to exinguish the flame by excluding oxygen, and the cooling
effect also helps drive the temperature of the combustible
material below that required to support compustion. It is
used in situations where putting water on the fire might
cause undesirable damage.
