Fire Extinguishers…
The proper class of fire extinguisher should be used in case of fire.
Class A extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics.
The numerical rating on these types of extinguishers indicates the amount of water it holds and the amount of fire
it can extinguish. Geometric symbol (green triangle).
Class B fires involve flammable or combustible liquids such as gasoline, kerosene, grease and oil. The numerical
rating for class B extinguishers indicates the approximate number of square feet of fire it can extinguish.
Geometric symbol (red square).
Class C fires involve electrical equipment, such as appliances, wiring, circuit breakers and outlets. Never use
water to extinguish class C fires - the risk of electrical shock is far too great! Class C extinguishers do not have a
numerical rating. The C classification means the extinguishing agent is non-conductive. Geometric symbol (blue
circle).
ABC fire extinguishers are a dry chemical type used for multiple purposes. See above information for description.
Ensure fire extinguishers are serviceable and replace any that are discharged or out of inspection dates.
