Fire Extinguishers

The ABC’s of Fire Extinguishers

Fire extinguishers when properly used, are able to keep a small house fire from turning into a major fire emergency. Typical household fires are one of three types: combustible solids, flammable liquids or electrical. In order to protect against all three, get a fire extinguisher labeled ABC.

Class A fires consume combustible solids such as paper or wood. This type of extinguisher emits water or foam to put out the Class A fire.

Class B fires are those caused by flammable liquid such as grease, oil or gasoline. Foam, dry chemical and carbon dioxide will put out this fire. Do not use water because it will only spread the fire.

Class C are fires started by live electricity. With the power turned off, the fire lessens in severity and becomes a Class A or Class B fire.  Use CO2 or dry chemical extinguisher on electrical fires. Never use foam or water because you could suffer a serious electrical shock or spread the fire.

Steps in Using an Extinguisher

1)      Have someone call the fire department. Alert everyone to flee the building. Remove the extinguisher, set it on the floor and pull the lock pin as shown on the side of the extinguisher.

2)      Stand at least 6 feet away from the flames. Keep your back to the doorway so you can make a speedy exit. Hold the extinguisher upright with both hands and aim at the bottom of the flames.

3)      Squeeze the levers of the release handle together and sweep the stream of propellant across the base of the flames. Spray until the flames are extinguished or fire becomes too severe to continue.

4)      Leave the house and let the firefighters do the rest.

Shopping Tips

Just as when purchasing an alarm system it is important also to have the extinguisher you chose be rated by a non-biased independent testing agency such as Underwrites Laboratory. Also keep in mind the size of the extinguisher you want. Home models typically range from 10 to 36 pounds. Think about the number of extinguishers you will need. Buy one for each kitchen, basement and garage. Read the instructions carefully and with the whole family to make sure everyone can operate it. Recheck the fire extinguishers monthly to ensure they are fully charged. Mount each extinguisher near a doorway and away from fireplace or wood stove. Place it at least five feet about the ground for easy access and away from low burning flames.
