Water Extinguishers –

These extinguishers are water-filled tanks using carbon dioxide or nitrogen as propellants. Water extinguishers are the most widely used type of extinguisher, helping eliminate heat from fire while cutting off the supply of oxygen.


Foam Extinguishers

These are foam-filled extinguisher tanks using nitrogen as their propellants. Foam extinguishers work by smothering the fire, absorbing its heat. When used, the foam spreads thinly over the fire, cutting oxygen supply and containing the heat. Its heat-absorbing property is aided the water the foams contains..


Dry Powder Extinguishers

These extinguishers contain dry powder, using nitrogen as their propellants. In this use case, dry powders help absorb heat, then melt and coat the fuel, consequently cutting off the oxygen supply and containing the fire. Dry powder is typically a mixture of chemicals, including mono-ammonium phosphate, potassium bicarbonate, sodium bicarbonate, etc..


Carbon Dioxide Extinguishers

CO2 extinguishers have gaseous and liquid carbon dioxide in their tanks, stored under high pressure to liquify it even further. When released, the gas expands, smothering oxygen and absorbing surrounding heat when it turns from a liquid into a gas (the latent heat of vaporization).
