Three ways to extinguish a fire
• Starvation - Removal of fuel
• Smothering - Removal of oxygen
• Cooling - Removal of heat
• Remove any one of the three
components and fire cannot start or be
sustained

Remember!Extinguishers are only for dealing with
small fires.
DO NOT CONTINUE TO FIGHT A FIRE IF:
• it is dangerous to do so,
• there is a possibility that your escape route may be cut off by the fire or smoke,
• the fire continues to grow in spite of your efforts,
• there are gas cylinders threatened by a fire.
• If you have to withdraw, close windows and doors behind you whenever possible.
• Do NOT use a fire extinguisher to put out a fire involving burning gas. Turn off the gas supply if it is safe to do so, or leave such fires to the fire brigade.
