How to Use a Fire Extinguisher

Underwriters Laboratories Inc. (UL) offers the following tips for selecting and properly using a fire extinguisher:

Select a multi-purpose extinguisher (rated A, B or C) with the UL Mark that can be used on all types of home fires such as wood, cloth, paper, flammable liquids such as gasoline, oil, grease, oil-based paint, and energized electrical equipment including wiring, fuse boxes, circuit breakers and appliances.
Know how the extinguisher works before you need to use it. When there's a fire, there is no time to find the instruction booklet or study instructions printed on the extinguisher.
To operate a fire extinguisher, remember the word PASS:

Pull the pin, hold the extinguisher away from you and release the locking mechanism
Aim low, pointing the extinguisher at the base of the fire
Squeeze the lever slowly and evenly
Sweep the nozzle from side to side

Stand at least 6 feet away from the fire and have your back to a door so you can escape easily, if necessary.
