It's not rocket science... but have you ever used a fire extinguisher?
PULL the pin out
AIM the extinguisher nozzle at the base of the fire
SQUEEZE the handle of the fire extingusher
SWEEP from side-to-side at the base of the flame
Stay low, out of the smoke, as it contains superheated gases, carbon monoxide and other toxins.
Fire extinguishers work by eliminating one or more element of the fire triangle 🔺 HEAT OXYGEN FUEL
Remove any one element, and you will extinguish the fire.
Do you know which extinguishers to use on different types of fires?...
-Water (plain red): Class A fires which include papers, textiles, woods, most plastics and rubber fibres.
Water lowers the temperature of the burning material to below ignition point (removes the heat).
REMEMBER NEVER TO USE WATER ON COOKING OIL/FAT FIRES, FUEL FIRES & ELECTRICAL FIRES.
-Foam (red with blue band): Class A & B which include papers, textiles, woods, plastics, rubbers, petrol, oils and paints.
The foam covers a burning flammable liquid with a blanket, cutting off the air supply to the fire and preventing the release of flammable vapours (removes the oxygen).
-CO2 (red with black band): Class C which includes energised electrical items.
Carbon dioxide is a non-conductive, non-corrosive gas used to reduce the amount of oxygen available to the fire. There is a high likelihood of re-ignition, because heat and fuel sources are not removed, and oxygen returns once the CO2 dissipates.
-Powder/Dry Chemical (red with white band): Class A, B & E which includes a wide range of fires that may occur in a house, workplace, boat, garage, car or caravan. This is the most versatile and widely used extinguisher.
The fine powder absorbs fuel molecules, depriving the fire of a fuel source.
