When used properly, a portable fire extinguisher
can save lives and property by putting out a small fire or controlling
it until the fire department arrives. Portable extinguishers, intended
for the home, are not designed to fight large or spreading fires.
However, even against small fires, they are useful only under certain
conditions:
- The operator must know how to use the extinguisher.
There is no time to read directions during an emergency.
- The extinguisher must be within easy reach and in working
order, fully charged.
- Some models are unsuitable for use on grease or electrical
fires.
Choose your extinguisher carefully. A fire extinguisher
should bear the seal of an independent testing laboratory. It should
also be labeled with the type of fire it is intended to extinguish.
The extinguisher must be large enough to put
out the fire. Most portable extinguishers discharge completely
in as few as eight seconds.
Classes of fires: There are
three basic classes of fires. All fire extinguishers are labeled
with standard symbols
for the classes of fires they can put out. A red slash through
any of the symbols tells you the extinguisher cannot be used on
that class fire. A missing symbol tells you only that the extinguisher
has not been tested for use on a given class of fire.
Class A: Ordinary combustibles such as wood,
cloth, paper, rubber, and many plastics.
Class B: Flammable liquids such as gasoline,
oil, grease, tar, oil-based paint, lacquer, and flammable gas.
Class C: Energized electrical equipment including
wiring, fuse boxes, circuit breakers, machinery, and appliances.
Many household fire extinguishers are "multipurpose" A-B-C
models, labeled for use on all three classes of fire. If you are
ever faced with a Class A fire, and you don't have an extinguisher
with an "A" symbol, don't hesitate to use one with the "B
C" symbols.
Extinguisher sizes: Portable extinguishers are
also rated for the size of fire they can handle. This rating is
a number from 1 to 40 for Class A fires and 1 to 640 for Class
B fires. The rating will appear on the label. The larger the number,
the larger the fire extinguisher can put out. Higher-rated models
are often heavier. Make sure you can hold and operate the extinguishers
rated 1A or 2A and/or 5B, 10B, or 20B.
Extinguishers should
be installed in plain view, above the reach of children, near
an escape route and away from stoves and heating
appliances.
Extinguishers require routine care. Read your
operator's manual and ask your dealer how your extinguisher should
be inspected
and serviced. Rechargeable models must be serviced after
every use.
Disposable fire extinguishers can be used only once; they must
be replaced after one use. Following manufacturer's instructions,
check the pressure in your extinguishers once a month.
Stand 6 to 8 feet away from the fire and follow
the four-step PASS procedure. If the fire does not begin to go
out immediately, leave the area at once. Always be sure the fire
department inspects the fire site.
PULL the pin out: This unlocks the operating
lever and allows you to discharge the extinguisher. Some extinguishers
have other devices that prevent inadvertent operation.
AIM low: Point the extinguisher nozzle (or hose)
at the base of the fire.
SQUEEZE the lever below the handle: This discharges
the extinguishing agent. Releasing the lever will stop the discharge.
Some extinguishers have a button that you press.
SWEEP from side to side: Moving carefully toward
the fire, keep the extinguisher aimed at the base of the fire and
sweep back and forth until the flames appear to be out. Watch the
fire area. If the fire re-ignites, repeat the process.
Before you begin to fight a fire:
- Make sure everyone has left, or is leaving, the building.
- Make
sure the fire department has been notified by dialing 911.
- Make sure the fire is confined to a small area and that it
is not spreading beyond the immediate area.
- Make sure you have
an unobstructed escape route where the fire will not spread.
- Make sure that you have read the instructions and that you
know how to use the extinguisher.
It is dangerous to fight a fire under any other circumstances.
Instead, leave immediately and close off the doors and windows
if possible.
