Diagram – Fire safety
Suitable for all providers
For a fire to start and to continue to burn, three things are needed: a heat source or source of
ignition, fuel and oxygen.
FUEL (flammable gases, liquids or solids
such as petrol, paper, wood, flammable
fabric, cooking fats, etc.)
FIRE
OXYGEN (present in the air
– small fires can be put out
by removing oxygen, i.e.
smothering)
HEAT OR SOURCE OF
IGNITION (such as a spark
from electrical equipment,
arcing, an open flame, friction,
chemical reaction, etc.)
Taking away any of these three components will prevent a fire from starting or will stop it from
continuing to burn. Taking steps to avoid the three coming together will therefore reduce the
chances of a fire occurring.
