Wet Chemical Fire Extinguishers

Wet Chemical Fire Extinguisher Use

Wet chemical fire extinguishers have been developed to effectively extinguish fires involving cooking oil - Class F fires.  Class F fires are notoriously difficult to tackle due to the high temperature of the burning oil. 

At Life Safety Online, our range of chemical fire extinguishers is best for cooking fires caused by fat and oils. Other fire extinguishers such as water extinguishers, foam, powder, and Co2 fire extinguishers will not put out big cooking fires and can be extremely dangerous if used for this type of fire. The oil and heat also break down standard fire extinguisher foam, rendering it useless.

How do Wet Chemical Extinguishers Work?

Wet chemical fire extinguishers are used to tackle kitchen fires with fat and grease (Class F), for example, deep fat fryer fires. Some wet chemical extinguishers can also tackle wood and paper fires (Class A) and petrol fires (Class B).

Wet chemical extinguishers work by a chemical reacting with the oil and forming a crust over the top, preventing burning or reignition - a process called saponification. This blocks the supply of oxygen and preventing the fire from growing.   The long applicator lance and fine spray make the application easy and safe.

The new MultiChem multi-class Foam Fire Extinguishers are also rated to tackle Class F fires due to the innovative and thick foam they produce.
