Wet Chemical Fire Extinguisher on pallet

Wet chemical extinguishers have a yellow label and are designed explicitly for Class F fires concerning kitchen fires caused by flammable cooking oils and fats, such as butter, lard, olive oil, and sunflower oil.

Moreover, wet chemical extinguishers can also be used for Class A fires caused by various organic materials, including wood, coal, textiles, and paper, but foam or water extinguishers are more commonly used. Although it is not typically used to extinguish Class B fires caused by flammable liquids such as diesel, alcohol, and paint, 3ltr Gloria wet chemical fire extinguisher is an exemption.

How It Works

The wet chemical extinguisher contains a solution of potassium which extinguishes the fire by spraying a fine mist that cools the fire to stop it from spreading. The mist also prevents the splashing of the scalding oil.

The potassium salts react with the hot oils, resulting in the saponification of the cooking oil’s surface, producing a foam layer. Saponify means to convert fats or oil into a soap due to the action of alkali. This soapy foam formed is non-combustible and acts like a cool blanket that serves as a barrier, sealing the surface and prevents reignition as it removes the heat and cuts off the oxygen supply. The chemical reaction that results in saponification only works on vegetable oils and animal fats; thus, most Class F fire extinguishers cannot be applied to Class B fires.

How To Use Wet Chemical Fire Extinguishers

This type of fire extinguisher should be located near the fire risk source in commercial kitchens and canteens.

Ensure that the pressure gauge is positioned in the green area and the safety pin is not bent to know if the extinguisher is fully charged.

If possible and safe, turn off the heat source and maintain a safe distance from the fire.

Remove the safety pin and squeeze the handle to apply the wet chemical.

Spray the mist in a gentle and slow circular motion to prevent splashing the hot oil.

Empty the extinguisher’s contents to ensure all the fire has been suppressed and to help prevent reignition.

When Not To Use Wet Chemical Fire Extinguishers

Wet chemical fire extinguisher is not advised to be used on fires involving electrical apparatus and equipment due to possible risks, including electrical shocks.
