Fire extinguishers use and inspection

1. Fire Extinguisher Use and inspectionFire Extinguisher Use and inspection
•Understand the combustion process and different
fire classes
•Understand fire extinguisher types, operating
procedures
•Understand basic firefighting concepts
P.A.S.S : PULL – AIM – SQUEEZE - SWEEP

2. The Combustion Process
•Three components
•Need all three components to
start a fire
•Fire extinguishers remove one
or more of the components.

3. Fire Classes

•Class “A” fires only
•2.5 gal. water
(up to 1 minute discharge time)
•Has pressure gauge to allow visual
capacity check
•30-40 ft. maximum effective range
•Can be started and stopped as
necessary
•Extinguishes by coolingcooling burning
material below the ignition point.

7. Fire Extinguisher Types (cont.)
•Class “B” or “C” fires
•2.5-100 lb. of CO
2 (8-30
seconds discharge time)
•Has NONO pressure gauge--capacity
verified by weight
•3-8 ft. maximum effective range
•Extinguishes by smotheringsmothering
burning materials
•Effectiveness decreasesdecreases as
temperature of burning material
increases.

8. Fire Extinguisher Types (cont.)
•Class “A”, “B”, or “C” fires
•2.5-20 lb. dry chemical
(ammonium phosphate)

11. Firefighting Decision Criteria
•Know department emergency procedures and evacuation routes
•Know locations of extinguishers in your area and how to use them
•Always sound the alarm regardless of fire size
•Avoid smoky conditions
•Ensure area is evacuated
•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
•If in doubt, evacuate!
