AVAILABILITY

Fire extinguishers are available campus-wide to put out small fires in University buildings. Do not attempt to put out a larger fire with a fire extinguisher. See 8.20. Report all fires to the local area fire department at 911.

RATINGS OF FIRE EXTINGUISHERS AND FIRES

Look on the front of a fire extinguisher to determine what sort of fire the extinguisher will put out. Usually, extinguishers are labeled with the letters A, B, C, or D. Each letter signifies a class of fires the extinguisher will suppress.

An extinguisher marked "A, B, C" will put out fires involving ordinary combustibles (e.g., paper and wood), flammable liquids, and electrical equipment.

IMPORTANT: Do not use an inappropriate extinguisher on a given fire. Such a practice can make the fire worse and/or cause injury to the user. A common error is the use of a water extinguisher (A) on a grease or electrical fire (B or C).

The higher the numerical classification rating on the extinguisher, the more fire it will put out.

A: Ordinary Combustibles

Fires in paper, wood, drapes, and upholstery require an extinguisher labeled A.

B: Flammable Liquids

Fires in fuel oil, gasoline, paint, grease in a frying pan, solvents, and other flammable liquids require an extinguisher labeled B.

C: Electrical Equipment

Fires started in wiring, overheated fuse boxes, conductors, and other electrical sources require an extinguisher labeled C.

D: Metals

Certain metals, such as magnesium and sodium, require special dry powder extinguishants labeled D.

USING A FIRE EXTINGUISHER

To operate most fire extinguishers:

Pull the pin. Some units require the releasing of a lock latch, pushing a puncture lever, inverting or other motion.

Aim the extinguisher nozzle (horn, or hose) at the base of the fire.

Squeeze or press the handle.

Shoot the retardant at the base of the fire, sweeping from side to side. Watch for re-flash. Do not discharge the total contents of the extinguisher unless necessary. If necessary, send another person for additional extinguishers in case of re-flash.

Although the above instructions apply to most extinguishers, there are exceptions, e.g., foam and water extinguishers require slightly different actions. Read the instructions on all extinguishers in or near the work area.

Before attempting to fight an electrical fire, turn off the power to the involved electrical device. Turn off the circuit breaker or switch, or unplug the device.

Training

Employees are encouraged to obtain training in fire extinguisher use. Employees may not obtain enough information from reading the labeled instructions on the fire extinguishers to properly use the extinguishers in an emergency.

The WSU Fire Marshal arranges training in the proper use of fire extinguishers upon request. Departments contact the WSU Fire Marshal to schedule training sessions; telephone 335-8548.
