Fire Extinguisher Types_____ PRESSURIZED WATER Class “A” fires only. 2.5 gal. water at psi (up to 1 minute discharge time). Has pressure gauge to allow visual capacity check ft. maximum effective range. Can be started and stopped as necessary. coolingExtinguishes by cooling burning material below the ignition point.

Fire Extinguisher Types (cont.) CARBON DIOXIDE (CO 2 ) Class “B” or “C” fires lb. of CO 2 gas at psi (8-30 seconds discharge time). NO Has NO pressure gauge-- capacity verified by weight. 3-8 ft. maximum effective range. smotheringExtinguishes by smothering burning materials. decreasesEffectiveness decreases as temperature of burning material increases.

Fire Extinguisher Types (cont.) DRY CHEMICAL Class “B”, or “C” fires. 30 lb. dry chemical (ammonium phosphate) pressurized with CO2 gas cartridge and wheeled extinguishers are pressurized with nitrogen cartridge. (8-25 seconds discharge time) ft. maximum effective range. smotheringExtinguishes by smothering burning materials. C. Electrical B Liquid, Grease

Fire Extinguisher Types (cont.) MULTIPURPOSE DRY CHEMICAL Class “A”, “B”, or “C” fires lb. dry chemical (mono ammonium phosphate) pressurized with CO2 gas cartridge and wheeled extinguishers are pressurized with nitrogen cartridge. (8-25 seconds discharge time) ft. maximum effective range. smotheringExtinguishes by smothering burning materials.

Fire Extinguisher Types (cont.) DRY POWDER DRY POWDER Class “D” combustible metal fires only. 30 lb. pressurized dry powder optimized for specific combustible metal (also available in bulk containers for hand scooping onto fire to extinguish). 4-6 ft. maximum effective range. To activate, must first open CO2 cylinder cartridge on back to pressurize body.(28-30 seconds discharge time) smotheringExtinguishes by smothering burning materials. D D COMBUSTIBLE METALS

Fire Extinguisher Types (cont.) WET CHEMICAL C Electrical Equipment Class “A”, “C”, and “K” fires. 1.5 gal. of stored pressure PRX wet chemical extinguishing agent (40 sec. discharge time) ft. maximum effective range. after On Class “K” fires, don’t use until after fixed extinguishing system has activated. cooling Extinguishes by cooling and forming foam blanket to prevent reigniting.

Firefighting Decision Criteria KnowKnow department emergency procedures and evacuation routes. KnowKnow locations of extinguishers in your area and how to use them. Alwaysregardless Always sound the alarm regardless of fire size. Avoid Avoid smoky conditions. Ensure Ensure area is evacuated. Don’t Don’t attempt to fight unless: - Alarm is sounded. - Fire is small and contained. - You have safe egress route (can be reached without exposure to fire). - Available extinguishers are rated for size and type of fire. evacuate! If in doubt, evacuate!
