Based on your home size, and the number of potential fire hazards, you should consider having one or more working extinguishers.
You should also choose the extinguisher type that best fits your needs.
Generally, there are three common classes of home fire extinguishers:
*Class A - These are for wood and paper fires. This class cools material below its ignition temperature and soaks fibers to prevent re-ignition.
*Class B - These extinguishers suppress flammable-liquid and grease fires. They work by removing oxygen from the area sprayed and preventing vapors from reaching the ignition source. The chemical reactions that remove oxygen and suffocate a fire.
*Class C - These models are for electrical fires. They use an extinguishing agent that is not capable of conducting electricity.
*Multi-Class - These chemical extinguishers can be used on different types of fires and are labeled with more than one letter-- A-B, B-C or A-B-C. (Note: Most multi-class extinguishers contain a corrosive agent that should be cleaned up immediately after use to percent damage to sprayed surfaces).
Extinguisher use - remember to P.A.S.S.:
*Pull the pin at the extinguisher top.
*Aim at the base of the fire.
*Squeeze the handle/lever to discharge. (Stand back 6-8 feet from the flame.)
*Sweep the spray back and forth at the base or source of the fire.
Home fire extinguishers along with maintained smoke detectors are important components to you home's fire defense system. Make certain all are working properly and maintained according to manufactures instructions.
