Fire are classified
into 4 categories according to the types of materials involved.
It is considered
that electricity does not constitute a class of fire because electricity is a
source of energy.
Is normal procedure is to isolate the
electricity and use fire extinguisher on the burning material. Only when this
cannot be done with certainty will special extinguishing agents be required
which are non-conductors of electricity and non-damaging to equipment: these
include dry power and carbon dioxide, although the latter’s cooling and
condensation effects may damage sensitive electronic equipment. Never use
water on electrical equipment, as water is good conductor of electricity
shock or electrocution may result if water is used on live electricity
