Fires come in 6 different classes:
|Class A||Combustible materials|
|Class B||Flammable Liquids|
|Class C||Flammable Gas|
|Class D||Flammable Metals|
|Class E||Electrical Fire|
|Class F||Cooking Oils & Fats|
Suitable for Class A Fires only, water extinguishers take away the heat element from combustible materials such as wood, paper or general trash.
Foam agents help to eliminate heat, and separate oxygen from other elements. It is useful in both Class A and B fires, while its effectiveness is limited in Class F fires.
Powder extinguishers involve dry chemicals, and such extinguishers are often used in homes. It is most effective in Class A, B and C fires.
CO2 extinguishers use carbon dioxide to extinguish electrical fires, or flammable liquid fires (Class B and E). The extinguisher is highly pressurized, and utilizes the property of non-flammability of CO2 for its function.
Wet Chemical Extinguishers are very useful for Class A and Class F fires, designed especially to quell fires started by cooking oils and fatty materials.
