FIRE
?
How do you extinguish a fire?
!
To eliminate the ignition of a fire, precautions must be taken
to reduce the combination of heat sources, flammable/
combustible materials and oxygen. Knowledge of how to
use a fire extinguisher safely in the event of a fire is critical.
Prevention Points
Fire is made of three components:
oxygen, heat and fuel. The elimination
of any one of the three components
will extinguish a fire either by
smothering, absorbing the heat or
shutting off and/or eliminating the fuel
source. Most fires can be put out with
a fire extinguisher marked A, B, C.
Fire Types
CLASS MATERIALS
A Ordinary combustibles (wood, paper, textile)
B Flammable liquids (gasoline, oil)
C Electrical currency (motor appliances)
D Combustible metals (magnesium, potassium)
Fire Safety Tips
Review the General Health & Safety Best Practices section on
page 11 before performing any task.
GENERAL
Store flammable and combustible materials away from all
heat sources.
Never fuel equipment inside a building. Store fuels outside the
building in clearly marked containers.
