As far as selecting the right fire extinguisher is concerned, you have to pay attention to the combustible fluids and materials. These materials can be found in different areas of the workplace or home. Most of the fire extinguishers used in the workplace feature the plunger mechanism. This means they work by releasing extinguishing agents. The common types of fire extinguishers are:
Foam Extinguisher
This type of portable extinguisher is effective at extinguishing class B fires. In most cases, it is located near flammable liquids. The main types of Fire Extinguishers are mechanical and chemical. The chemical foam extinguisher uses aluminum sulfate and sodium bicarbonate chemicals. When you struck the plunger, the two chemicals mix to produce carbon dioxide, which forces out the foam. These fire extinguishers are not recommended in confined areas because they release poisonous gases.
Soda Acid Fire Extinguishers
This type of fire extinguisher is designed to put out Class A fires. These types of fire extinguishers are commonly installed in accommodation areas. The major components of the extinguishing agent include sulfuric acid and soda. When they are combined, they produce carbon dioxide gas that smothers the fire.
This fire extinguisher is designed to have a container that contains sodium bicarbonate, with a small part contain sulfuric acid. You need to strike the plunger to use it. It is not advisable to use this fire extinguisher in a confined place. That is because it releases toxic gases.
Water Extinguisher
This type of fire extinguisher is used to put off class A fires. The container is filled with water and features a carbon dioxide cartridge that ejects water out. When you apply pressure on the plunger, the cartridge ejects water to extinguish the fire.
Mechanical Foam
The extinguisher features two containers. Its outer one contains water, whereas the inner one contains foam solution and carbon dioxide. When the plunger mechanism is depressed, it releases carbon dioxide. This allows water and foam to mix, which then come out to extinguish the fire.
Carbon Dioxide Extinguisher
These types of fire extinguishers are used for class C and Class B fires. However, they are not recommended for confined areas. They contain carbon dioxide that is stored in liquid form. However, the liquid converts to gas when it is ejected.
Dry Powder Extinguisher
This fire extinguisher contains sodium bicarbonate that extinguishes nearly all types of fires. Some of these extinguishers contain a small amount of carbon dioxide.
