FACT:
Portable fire extinguishers save lives and property! Knowing
this, the Orwigsburg Fire Department has always encouraged
home and business owners to maintain a currently inspected
and working fire extinguisher in their home and or business.
The Orwigsburg Fire Department strongly encourages that
everyone understands the types of fire extinguishers that
are available, how to identify them, and how to operate
the extinguisher during a fire situation.
Common
Types of Fires
There
are FOUR common types of fires that any household or business
could experience. They are described, and labeled, as such:

CLASS
A fires consist of only ordinary combustibles such as
wood and common household trash (paper).
CLASS B fires are those that are burning due to a
flammable liquid such as gasoline or kerosene.
CLASS C fires are fires that have a continuous feed
of electrical current to the object that is on fire (i.e
your computer). Once the electrical current has been broken,
or cut, the electrical equipment that is on fire is now
considered a Class A or Class B fire, depending on the situation
and object(s) on fire. Never cut any wires or cables to
break the flow of electrical current to an object that is
on fire! If it is safe, you can cut power to the object
from a grounded source like a power switch or breaker. Always
take the proper precautions and treat the fire as a Class
C fire. This is why it is always ideal to keep a Class A-B-C
extinguisher in your home, or in the office.
CLASS D fires, and least common, are fires that are
caused and maintained due to combustible metals such as
magnesium.
Types
of Fire Extinguishers
There
are several types of fire extinguishers available to the
public.
- Dry
Chemical Extinguishers.
The terms dry chemical and dry powder are often incorrectly
used interchangeably. Dry chemical extinguishers are commonly
used on Class A-B-C fire and or Class B-C fires. Dry powder
agents, or dry powder extinguishers, are for Class D fires
only.
- Halon
Extinguishers.
These extinguishers are the least common due to their
ozone-depletion potential. Generally, halon extinguishers
are most common for Class B and Class C fires only. Because
halon extinguishers leave very little residue, they are
the most common for using on electrical equipment fires.
-
Water Extinguishers. Water
extinguishers are only water and are generally contained
under pressure. These extinguishers should only be used
for Class A fires.
- Carbon
Dioxide (CO2) Extinguishers.
These extinguishers are most effective on Class B and
Class C fires. The carbon dioxide is stored as a liquid
and will cool as it extinguishes. Because of this natural
reaction, cold frost crystals will form on the nozzle,
or horn, of a CO2 extinguisher.
Which
One Is Best For Me?
The
environment you either live in, or work in, will determine
which kind of extinguisher to own. Generally, all homeowners
and business owners should own a suitable amount of dry
chemical extinguishers, because of their effective use on
Class A-B-C fires. Always remember to use the appropriate
extinguisher for the job! For example, if your computer
is burning, or on fire, DO NOT use an extinguisher that
has this marking:

Please
use one that has this making instead!

Also,
please make sure that the extinguisher specifically shows
the symbol for Class C fires, because it is your computer
burning, not your dinner because you over cooked it!
How
Do I Use A Fire Extinguisher?
Always
remember P.A.S.S!
Pull
the pin. Hold the extinguisher with the nozzle pointing
away from you, and then release the locking mechanism.
Aim
low. Point the nozzle to the base of the fire.
Squeeze
the lever slowly and evenly.
Sweep
the nozzle from side to side as the extinguisher releases
its agent.
Last
Thoughts?
Choose
a fire extinguisher that carries the label of an independent
testing laboratory.
Read the instructions that come with the fire extinguisher
and become familiar with its parts and operation before
a fire breaks out. Local fire departments or fire equipment
distributors often offer hands-on fire extinguisher trainings.
Install
fire extinguishers close to an exit and keep your back to
a clear exit when you use the device so you can make an
easy escape if the fire cannot be controlled. If the room
fills with smoke, leave immediately.
Know
when to go. Fire extinguishers are one element of a fire
response plan, but the primary element is safe escape. Every
household should have a home fire escape plan and working
smoke alarms.
- Always
remember to have your fire extinguisher inspected yearly.
- Occasionally
check the pressure gauge on the extinguisher to ensure
proper pressure and to make sure the extinguisher is charged(full).
Remember, once you use a fire extinguisher once, it must
be recharged by a certified extinguisher service center.
You can find certified service centers in your local phone
book.
