Fire Extinguishers
Fire extinguishers aren't for everybody to use. They are only to be used if you're encountered with a small fire. You should also be an adult--and only then use one IF you know how to use it.
But don't put your extinguisher in a place that will take time to get to or find. That time spent searching or digging will allow the fire time to spread and become unmanageable for the extinguisher you want to use.
Extinguisher Types
There are three classes of extinguishers--A, B and C.
Class A extinguishers are labeled with a green triangle. These devices contain water, and can be used to put out wood, cloth or paper that has ignited.
Class B extinguishers are labeled with a red square. Class B extinguishers are used to put out flammable liquids such as gasoline, oil and oil-based paint. You can also use a Class B on a grease fire in a kitchen.
Class C extinguishers are labeled with a blue circle. These extinguishers are to be used on live electrical equipment--including wiring, fuse boxes, circuit breakers, machinery and appliances.
Don't use Class A (Water) Extinguishers on grease or electrical fires!
Multipurpose fire extinguishers with an A-B-C label may be used on all three types of fires.
A red slash through any of the symbols indicates you shouldn't use that extinguisher on that class of fire. A missing symbol tells you that the extinguisher hasn't been tested on that class of fire.
When to Use Them
Don't forget, fire extinguishers aren't made to do the job of a firefighter. If a fire is too hot or starting to spread--get out of the house!
Only use a fire extinguisher if:
- You are an adult
- You know how to operate it
- You are certain it's in working order
- It is readily accessible
- You have a clear escape route in case the fire spreads
- The extinguisher class matches the class of fire you're fighting
- The extinguisher is large enough to handle the fire
Some extinguishers are made to last only about 10 seconds. The label should tell you how long the device will last against a particular kind of fire.
How to Use Them
The National Fire Protection Association has devised an acronym to help you remember how to use a fire extinguisher: PASS. PASS stands for Pull, Aim, Squeeze, and Sweep.
Pull
the Pin - The pin unlocks the handle and lets you discharge
the extinguisher. But some devices have different handle-release
mechanisms. Be sure you're familiar with your extinguisher.
Aim
Low - Point the nozzle or hose at the base of the fire. That's
where the fire's fuel is--spraying the tops of the flames won't
do any good.
Squeeze
the Lever - Some extinguishers have a button instead of a lever,
but this is how you discharge the water or chemicals inside the
extinguisher. Releasing the handle or button stops the stream.
Sweep
the Base of the Fire from Side to Side - Carefully move toward
the fire as you move the stream from one side of the fire to the
other. Keep the stream aimed at the base of the fire. Sweep from
side to side until the fire is out. If the fire re-ignites, repeat
the process.
Remember, if a fire starts to get out of control, or your extinguisher runs out before the fire is out--get out and call the Fire Department!
