Types of Extinguishers

When it comes to flames a kitchen fire is a whole different situation than one set by combustible materials. Depending on the type of business, having different kinds of fire suppression may be necessary. Below are the general classifications of fire extinguishers based on the source:

Class A – Wood, paper or other combustibles
Class B – Flammable liquid or gas
Class C – Electrical fire
Class D – Metals
Class K – Animal fats or vegetable oils cooking fires

Along with the different classifications, there are different materials released to extinguish the flames.

ABC Powder – A multi-purpose type that sprays a fine chemical powder.
Carbon Dioxide – Removes oxygen from the flames, making it suitable for Class B use.
Wet Chemicals – For use on Class K fires and some Class A ones if it is wood or paper.
Water Mist – Emits de-ionized water molecules via a fog-like mist that are attracted to flames and is effective for Class A, B, C and K.
Foam – Mostly used for Class A and B, the foam expands to suffocate the fire.
Clean Agent – A gaseous suppression option for Class B and C fires.

How To Use
No matter which types are best for your business, all are fairly standard to use. Be sure to examine the unit for any damage before use and verify there is a safe exit route in case it doesn’t work. It’s better to be safe and call a fire damage and restoration company for repairs. Once you are ready to use, simply remember PASS:

• Pull pin.
• Aim nozzle at the base of the fire.
• Squeeze lever or handle.
• Sweep the nozzle back and forth.

Since not all fires and risks are the same, understanding how a fire extinguisher works and the different types available ensures your business is better prepared for the unexpected.
