Types
of Fires
Not
all fires are the same. Different fuels create different fires
and require different type of fire extinguishing agents.
CLASS
A - For fires in ordinary combustibles such as wood,
paper, cloth, trash and plastics.
CLASS
B - for fires in flammable liquids such as gasoline,
petroleum oil and paint and also include flammable gases such
as propane and butane. Class B fires do not include fires involving
cooking oils and grease.
CLASS
C - For fires involving energized electrical equipments
such as motors, transformers and appliances. Remove the power
and the Class C fire becomes one of the other classes of Fire.
Some
type of fire extinguishing agents can be used on more than one
class of fire.
Others
have warnings where it would be dangerous for the operator to
use a particular fire extinguishing agent.
Types
of Fire Extinguishers
FOAM(AFFF)
: AFFF(Aqueous Film Forming Foam) fire extinguishers
extinguish the fire by taking away the heat element of the fire
triangle. Foam agents also separate the oxygen element from the
other elements.
Foam extinguishers can be used on class A & B fires only.
They are not for use on Class C fire due to the shock hazard.
CARBON
DIOXIDE(CO2) :CO2 Fire Extinguishers extinguish the fire
by taking away the oxygen element of the fire triangle and also
by removing the heat with a very cold discharge.
CO2
can be used on Class B and C fires. They are usually ineffective
on class A Fires.
DRY
CHEMICAL POWDER (ABC) : Dry chemical fire extinguisher
extinguish the fire primarily by interrupting the chemical reaction
of the fire triangle.
Today’s
most widely used type of fire extinguisher is the multi purpose
dry chemical that is effective on Class A, B and C Fires
This
agent also works by creating a barrier between the oxygen element
and the fuel element on Class A Fires.
It
is important to use the correct fire extinguisher for the type
of fuel Using the incorrect agent can allow the fire to reignite
after apparently being extinguished successfully.
