Use Of a Fire Extinguisher

HOW TO IDENTIFY THE PROPER FIRE EXTINGUISHER

All ratings are shows on the extinguisher faceplate. Some extinguishers are marked with multiple ratings such as AB, BC and ABC. These extinguishers are capable of putting out more than one class of fire.

Class A and B extinguishers carry a numerical rating that indicates how large a fire an experienced person can safely put out with that extinguisher.

Class C extinguishers have only a letter rating to indicate that the extinguishing agent will not conduct electrical current. Class C extinguishers must also carry a Class A or B rating.

Class D extinguishers carry only a letter rating indicating their effectiveness on certain amounts of specific metals.

Remember the acronym, "P.A.S.S."—
P	......Pull the Pin.
A	......Aim the extinguisher nozzle at the base of the flames.
S	......Squeeze trigger while holding the extinguisher upright.
S	......Sweep the extinguisher from side to side, covering the area of the fire with the extinguishing agent.
