TYPES OF FIRES
Class A fires are fires in
ordinary combustibles such
as wood, paper, cloth, trash,
and plastics.
Class B fires are fires in
flammable liquids such
as gasoline, petroleum oil,
and paint. Also included
are flammable gases such
as propane and butane.
Class B
fires involving
and grease.
fires do not include
cooking oils
• the fire is small and not
spreading
• you know how to operate
the fire extinguisher, and
• the fire won't block your
unobstructed escape route

Association (NFP

Class C fires are fires involving
energized electrical equipment
such as motors, transformers,
and appliances. Remove the
power and the Class C fire
becomes one of the other
classes of fire.
Class D fires are fires in
combustible metals such as
potassium, sodium, aluminum

TYPES OF EXTINGUISHERS
Dry Chemical fire extinguishers extinguish the
fire primarily by interrupting the chemical reaction
in the fire. Today’s most widely used type of
fire extinguisher is the multipurpose 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.
Ordinary dry chemical is for Class B & C fires only.
It is important to use the correct extinguisher for
the type of fuel! Using the incorrect agent can
allow the fire to re-ignite after apparently being
extinguished successfully.
Water and Foam fire extinguishers extinguish
the fire by taking away the heat from the fire.
Foam agents also separate the oxygen from the
fuel and heat. Water extinguishers are for Class A
fires only, they should not be used on Class B or C
fires. The discharge stream could spread the
flammable liquid in a Class B fire or could create a
shock hazard on a Class C fire. Foam extinguishers
can be used on Class A & B fires only. They are not
for use on Class C fires due to the shock hazard.
Carbon Dioxide fire extinguishers extinguish
the fire by separating the oxygen element from the
fuel and heat, and also by removing the heat with
a very cold discharge. Carbon dioxide can be used
on Class B & C fires. They are usually ineffective on
Class A fires.
Halogenated or Clean Agent extinguishers
are either based on halocarbon agents or on the
older and no longer made halon 1211 agent,
which can no longer be used for training.
Halocarbon agents replaced halon 1211 within the
last 8 years and are much more environmentally
acceptable. Commercialized halocarbon agents
extinguish the fire by removing heat from the
combustion zone. Halon 1211 extinguishers, however, were chemically active and interfered with
the chemical reactions occurring in the combustion
zone. Halocarbon and halon 1211 extinguishers
are effective on Class A, B, and C type fires,
although very small sizes do not achieve the
lowest UL Class A rating, 1-A.
Dry Powder extinguishers are similar to dry
chemical except that they extinguish the fire by
separating the fuel from the oxygen element of
the fire.
for Class D or combustible metal fires, only. They
are ineffective on all other classes of fires.
However, dry powder extinguishers are
Water Mist extinguishers are a recent develop-
ment that extinguishes the fire by taking away
the heat from the fire. They are an alternative to
the clean agent extinguishers where contamination
is a concern. Water mist extinguishers are primarily
for Class A fires, although they are safe for use on
Class C fir
es as well.
Wet Chemical is a new agent that extinguishes
the fire by removing the heat from the fire and
prevents re-ignition by creating a barrier between
the oxygen and fuel elements. Wet chemical or
Class K extinguishers were developed for modern,
high efficiency deep fat fryers in commercial
cooking operations. Some may also be used on
Class A fires in commercial kitchens.
