Each extinguisher is required to have a label from the Underwriters Lab., or Factory Mutual Testing Lab. The Underwriters Laboratory labels are identified by the letters UL in a circle. Once you find the label look for the word "classification." On the right side or just below this, you will see a series of numbers and letters. For example you may see "2-A:10-BC." Remove the numbers and what you have are the letters "ABC", this is the designation of the class of fire(s) the unit is to be used on. The numbers may be different but you still read them the same, i.e., 60-BC would be for class B & C fires only.

Stainless steel, weighs about 35 lbs., holds 2 1/2 gals., it will reach up to about 35 ft., and will last approx. 1 minute. Class "A" only. It cannot be used on electrical or flammable liquid fires. This type works better as a spray by putting your finger over the end of the nozzle.

The best general purpose extinguisher. Comes in "BC" or "ABC" (multipurpose). Available in different sizes. It has a range of 8 to 12 ft. It will empty in 10 to 20 seconds. This is an excellent choice for home use. It can be messy when used, but it is nontoxic. We recommend all homes have at least two dry chemical-type fire extinguishers (at least one per floor) with a minimum size rating of 2A-10BC, including an earthquake restraining strap, a hose-type nozzle, and a metal head.

These are "BC" only. It is a gas that smothers the fire. They do not have a gauge. They reach about 2 to 5 ft., you have to get fairly close to the fire. For that reason always give a test shot before committing to the fire. Do not hold the coneshaped nozzle because it may freeze to your hand.

These are also "BC" only. They come in various sizes. They are used in specialized applications involving electronics and aircraft. Older types are illegal to refill because of ozone depletion. Newer formulas are becoming available.

Classifications of Fires

• "A"-type fires are common combustibles, i.e., wood, paper, cloth

• "B"-type fires are flammable liquids, i.e., gas, oil, grease 

• "C"-type fires are electrically energized fires, i.e., computers, toasters, heaters, appliances

For Fire Extinguisher Operation Remember

• P - Pull the pin

• A - Aim at the base of the fire

• S - Squeeze the handle

• S - Sweep the fire
