Learn More About the Different Types of Fire Extinguishers

• Pressurized water models -These are appropriate for use on a Class A fire only. These must never be used on electrical or flammable liquid fires.
• Carbon dioxide - These extinguishers contain pressurized liquid carbon dioxide, which turns into a gas when expelled. These models are rated for use on Class B and C fires but can also be used on a Class A fire. Carbon dioxide does not leave a residue.
• Dry chemical extinguishers - They come in either stored-pressure models or cartridge-operated models. The stored-pressure models have a lever above the handle for operation. The cartridge-operated models require two steps: depress the cartridge lever and then squeeze the nozzle at the end of the hose. The dry chemicals leave a residue that must be cleaned up after use.
• Ammonium phosphate - This is a dry chemical that can be used on Class A, B, and C fires but should never be used on a fire in a commercial grease fryer because of the possibility of reflash and because it will render the fryer's automatic fire protection system less effective.
• Sodium bicarbonate - This dry chemical, suitable for fighting Class B and C fires, is preferred over other dry-chemical extinguishers for fighting grease fires. Where provided, always use the extinguishing system first. This also shuts off the heat to the appliance.
• Potassium bicarbonate, urea-based potassium bicarbonate, and potassium chloride - These dry chemicals are more effective and use fewer agents as compared to sodium bicarbonate on the same fire.
• Foam (or AFFF and FFFP) extinguishers - These extinguishers function by coating the surface of a burning flammable liquid with chemical foam. When using a foam extinguisher, blanket the entire surface of the liquid to exclude the air.
