Wet Chemical Fire Extinguishers

Depending on the type or class of fire, there are different kinds of fire extinguishers that are accessible in the market and are used to extinguish the fire in case of emergencies and fire accidents. The fire class is determined by the type of combustible material that is being ignited in the fire incident. It can be paper, wood, fabric, flammable gas and liquids, flammable metals and fire caused by electrical wires and even fire caused by cooking fats and cooking oils.

Choosing the right fire extinguishers

The most common fire accidents are those, which occur when combustible materials like paper, wood, fabric, etc. are ignited. This type of fire is known as the Class ‘A’ fire. Another fire class common in households, hotels, and restaurants is that which is caused by cooking fat and cooking oil known as Class ‘F’ fire. When an accident of fire occurs due to these types of combustible materials and cooking fats, it is imperative that you choose the right extinguishers to put out the fire.

When you are choosing the right type of fire extinguisher, it is a must that you keep the type of material that has caused the fire, in mind. In the case of Class ‘F’ fire; if you use the usual extinguisher of fire, the water, foam, CO2 or foam will cause the ignited combustible materials like the oil or fat to jet out due to the high pressure of the extinguisher. This would be extremely dangerous. In that case, you need to choose the wet chemical extinguishers.
Mechanism of the wet chemical extinguishers.

Wet Chemical Fire Extinguishers

The wet chemical fire extinguishers use a solution of potassium that can effectively extinguish the fire by attacking it in two ways. Firstly the misty potassium solution will cool down the fire and also the temperature of the combustible material will also fall. Moreover, the oil and fat that could have jetted out would also not splash around, and the fire would not spread.

Another very advantageous working mechanism of the wet chemical fire extinguishers is that the salt of potassium reacts with the lard, sunflower oil, olive oil, butter and maize oil and all other types of cooking fats and oils. Thus, along with reducing the temperature, it also reacts with the oil and forms a soap-like solution through saponification process. This soapy material forms a layer of the fat, and this is incombustible. Hence, there is no further possibility of the fire spreading around.

Having wet chemical extinguishers handy:

For fire protection from Class ‘A’ fire and Class ‘F’ fire, it is a must that you have these wet chemical fire extinguishers at your access. It is of particular importance to have them available and accessible easily at restaurants, hotels and even at home kitchens. But, before you buy one for you, make sure that it abides by the Code of Practice as given by the BSI or British Standards Institution. A fire safety equipment installer that follows the BSI standards and offers maintenance services along with the installation of new systems and equipment can always be trusted.
