The extinguisher must be appropriate for the type of fire being fought. Multipurpose fire extinguishers, labeled ABC, may be used on all three classes of fires. If you use the wrong type of extinguisher, you can endanger yourself and make the fire worse. In some cases, it may be dangerous to use any type of fire extinguisher. An extinguishing agent released under pressure could, for example, spread a grease fire in a frying pan rather than put it out.
Extinguishers require routine care.
Read your operator's manual to learn how to inspect your extinguisher. Follow manufacturer's instructions for maintenance. Rechargeable models must be serviced after every use. Disposable fire extinguishers can be used only once and must be replaced after use. Remember the PASS-word KEEP YOUR back to an unobstructed exit and stand six to eight feet away from the fire.
