Fire Extinguisher’s:
How and Which Ones
to Use
|
A fire extinguisher is your best defense against small,
contained fires that have just started. Extinguishers are not meant to supplement
the fire department, they are only meant to control flames until the fire
department arrives, or buy enough time to get you out of the burning structure.
In order for a fire extinguisher to be used to it’s full potential, you must
learn which type to use, and how to use it correctly.
Classification of Fuels
There are several types of fire extinguishers; each one is
designed to fight a certain class, or classes of fire. Each class of fire is determined by the type of fuel for which might burn. Your
knowledge of each class will help you to decide which is the appropriate
type of extinguisher. Not all extinguishers can put out the same type of fire,
using the wrong type can cause the fire to spread, and could place you in greater
danger. Below are the three most common classes of fire extinguishers.
|
|
|
Type A
extinguishers fight ordinary combustibles such as wood, cloth and paper. |
|
|
|
Type B extinguishers fight flammable liquids, grease
and gas fires. |
|
|
|
Type C
extinguishers fight energized electrical equipment including wiring, fuse boxes, circuit
breakers, machinery and appliances.
|
Fire extinguisher's can be used to fight more than one
class of fire, but be sure to check the manufacturer's label to ensure proper
usage.
Location, Location, Location…
The placement of your extinguisher is another important
aspect. They should be placed in highly accessible, high-traffic locations.
Mount extinguishers on wall brackets no higher than five feet from the floor to
the top of the extinguisher. Place them in hazardous areas, and near exits.
Do You Know the P.A.S.S. Word?
To use a fire extinguisher safely, stand six to eight feet
from the fire and use the PASS procedure.
Pull
- Pull the pin. This will unlock to extinguisher and allow you to discharge it.
Aim
- Aim the nozzle, horn or hose at the base of the flames.
Squeeze

Releasing the lever will stop the discharge.
Sweep
- Sweep from side to side moving carefully toward the fire, and keep the
extinguisher
aimed at the
base
of the flames, until the fire is extinguished.
Servicing
Be sure to service rechargeable extinguishers, and replace
disposable models immediately after use. Inspect extinguishers for damage,
corrosion, or tampering regularly.
