METAL FIRESPotassium, sodium and ca

METAL FIRES
Potassium, sodium and calcium decompose water readily, liberating
hydrogen. These metals are all used in industry but not as widely as the “light
metals” which are widely used in aircraft and motor vehicles industries and in
the trades where lightness is desirable attribute. Magnesium, some of its
alloys and titanium are easily ignited when in the forms of wire, powder,
turnings of swarf: aluminum in similar forms is capable of burning.
The dusts may form inflammable and explosives mixture with air.
Water applied to any of these fires is decomposed, giving off hydrogen,
which aggravates the fire and may give rise to explosions which would
scatter the burning metal. Other metals too, e.g. zinc, in finely – divided
form are combustible.
Water, foam, carbon tetrachloride, methyl bromide, chlorobromomethane
or carbon dioxide, in fact, none of the usual extinguishers may be used on
metal fires. They are all ineffective and most of them are dangerous, because
they are liable either to cause the explosion or to do more harm than good by
scattering the burning metal.
Gas-expelled dry powder extinguishers are unsuitable for the latter
reason, but there is one specially-constructed model which discharges
through a long tube in a cone-shaped nozzle by which powder is delivered
lightly onto the fire. The solid extinguishing agents that find little application in
firefighting generally, are of value in dealing with metal fires. They must be
applied gently in order to cover the burning metal without disturbing it, and
care is necessary, as some scattering may, nevertheless, occur. Dry sand,
talc, mixture of asbestos dust and graphite may be used. Asbestos handclothes
or blankets are useful where small quantities of metal are involved,
not so much to extinguish the fire as to prevent its spread.
