If you use the wrong type of extinguisher, you can endanger yourself and make the fire worse. Cooking oil fires in a pan can be snuffed out by using a tight-fitting lid and turning the heat source off. The only appropriate agents are sodium or potassium bicarbonate. Discharging the extinguisher closer than six to eight feet may spread the fire. Installation and Maintenance Extinguishers should be installed in plain view, above the reach of children, near an escape route, and away from stoves and heating appliances.
Extinguishers require routine care.
Read your operator's manual to learn how to inspect your extinguisher. Follow manufacture's instruction for maintenance. Rechargeable models must be serviced after every use. This unlocks the operating lever and allows you to discharge the extinguisher. Some extinguishers may have other lever-release mechanisms.
