Portable Fire Extinguishers
 Portable fire extinguishers are intended as a
first line of defense to cope with fires of
limited size.
 Portable fire extinguishers are not a
substitute for assistance by the Emergency
Response Team (ERT), who are trained to
operate other fire Suppression Equipment.
 If a fire occurs, have another employee
activate the fire alarm to summon the ERT,
before operating portable fire extinguishers.

 Assess the fire and select the suitable
extinguisher by it’s classification.
(Extinguishers are classified by fire types
according to the extinguishing agent
loaded in them, and are effective for only
the types of fire indicated. Improper use
can cause personal injury as well as
aggravate the fire situation).
g
Symbols & Shapes
• In order to make the selection of the
correct fire extinguisher easier, fire
extinguishers have labels.
• Each label indicates the fire class the
extinguisher will extinguish.
• There are two ways to label fire
extinguishers.

Combinations
– Some extinguishers are suitable for putting out more than one
class of fire. A quick glance at the symbols will show the
classes of fire that can be extinguished.
– These are frequent combinations. A red line across the image
indicates this extinguisher may not be used for that class of
fire.
• This symbol indicates the extinguisher
may be used for Class A, B, & C fires.
• This symbol indicates the extinguisher
may be used for Class B, & C fires but

The P-A-S-S Method
• The easiest way to remember how to
use a fire extinguisher is by using the
P-A-S-S method.
P - Pull the pin
A - Aim the extinguisher
S - Squeeze the handle
S - Sweep the agent from
side to side at the base
of the fire

FIRE
If you encounter a fire, let the letters of
the word "FIRE" remind you of the
four basic steps for a safe and a proper
response.
g
Fight or Flee ?
• Incipient fire fighting (fighting a fire in it's early
stages) can save property and lives. But correctly
assessing the situation and determining if the fire
can be safely extinguished with a portable fire
extinguisher is the first and most important step
you must take.
• If there is too much smoke, or if the fire could
worsen and block your way of escape, then fleeing
to safety would be the safest choice.
g
Identify
• Identify the type of fire and quickly locate
the proper extinguisher for this type of fire.
If you cannot find the correct extinguisher,
it is best to not try to fight the fire.
g
Review
• Review how to properly use the
extinguisher BEFORE you approach the
fire. Use the P-A-S-S method for fire
fighting reviewed earlier in this course.
g
Extinguish
• Extinguish the fire. This can also remind
you to evacuate yourself and others and to
call emergency service personnel for help.
