What wet chemical fire extinguishers are used for?
Wet Chemical Extinguishers contain a solution of potassium, this solution smothers the fire and removes the element of heat. It prevents re-ignition by creating a barrier between the oxygen and fuel elements. They are most effective on Class A and Class F fires, which involve combustible materials such as wood, paper, and cooking oils.
Wet chemical fire extinguishers are typically used for fires that involve cooking oils and fats, such as in commercial kitchens. Wet chemical extinguishers work by spraying a fine mist of potassium acetate, potassium carbonate, or a similar agent onto the burning oil or fat. The mist cools the fire and forms a layer of foam that prevents oxygen from reaching the burning oil, which extinguishes the fire.
Where to Use Wet Chemical Fire Extinguishers?
If you own a restaurant, café, fast food, or any other type of food business, you probably know that kitchen cooking is the primary cause of fire in these kinds of businesses.
A wet chemical fire extinguisher is the only extinguisher safe to use for fires caused by grease, cooking oil, and fat fryers. The wet Chemical Fire Extinguisher comes with a specialized long applicator that is used to lay a cooling layer of extinguishing agent on top of the burning oil. To control the fire, remove the safety pin, aim the nozzle at the base of the flames, squeeze the lever gently, and make a sweeping motion from side to side to put out the fire thoroughly.
How do you identify a wet chemical fire extinguisher?
Wet chemical fire extinguishers can be identified by their red cylinder and a yellow band that runs around the top indicating the type of extinguishing agent inside. Wet chemical extinguishers are often used in kitchens to put out Class F fires involving cooking oils and fats. In addition to the label, wet chemical extinguishers typically have a unique nozzle or spray head that is designed to apply the extinguishing agent as a fine mist or spray.
It is important to note that wet chemical extinguishers should only be used on Class F fires and should not be used on other types of fires, such as electrical fires or fires involving flammable liquids. If you are unsure which type of fire extinguisher to use, you should evacuate the area and call the fire department for assistance.
How to use a Wet Chemical Fire Extinguisher?
Just remember the word PASS. It stands for the following:
P – This stands for pulling the pin off the top of the device. Pulling the pin is a way to unlock the device.
A – This stands for aiming at the base of the flame. Before releasing its content, point the nozzle at the source of the fire. Aiming at the flame will not stop the fire.
S – The first S stands for a squeeze. Squeeze the handle to release the content of the extinguisher.
S – The second S is for the sweeping motion. While squeezing the lever to release, do a sweeping motion. This is necessary to put out the fire from its base.
All the adults at home should know how to use the tool. In the workplace, you can invite someone to conduct fire safety training. Teaching the employees how to use the extinguisher is part of it.
Proper operation of the Wet Chemical Fire Extinguisher is essential because this would contribute to the effective extinguishing of the flames. Attempt to put out the fire only if it is still small and not yet spreading. You should have your back behind a fire exit to ensure that you can escape if it has gotten out of control. If these conditions are not present, you should evacuate the premises immediately and then call the fire brigade once you are safely out of the building.
