• What type of extinguisher(s) are available

• Where they are• That they are ready to use• How to use them

Fire Tetrahedron

• Fuel• Heat enough to raise

the fuel to its ignition temperature

• Oxygen enough to support combustion

• Chemical Chain Reaction

Pre-work Check

• Gauge– Extinguisher is full– If no gauge, check weight

• Hose and nozzle– In good repair with no damage

• Canister– In good repair with no damage– Hydro testing date

When to Fight the Fire

Attempt to use an extinguisher only if:

• Occupants are being evacuated or relocated to a safe area

• The fire department is being called or alarm has notified

• The fire is small and contained

• The exit is clear and you can fight fire with your back to the exit

When to Fight the FireThink about this:

Because of the speed of fire development and FD response times

staff use of extinguisher may be the only hope

for non-self preserving individuals

in a vehicle fire

When to Fight the Fire

Attempt to use an extinguisher only if:

• The proper extinguisher type is available

• You are trained and confident about using the fire extinguisher

• You can stay low and avoid breathing smoke

Use extinguishers safely

• Never turn your back on the fire• Never put the fire between you

and the exit• Use the reach of the extinguisher

for safety• If you don’t think that you can

fight the fire effectively don’t even attempt it

Fire is:

FAST

Portable fire extinguishers should be viewed as a

defensive weapon to aid in safe evacuation or relocation if

needed
