Types of Fire Extinguishers
Fire extinguishers are available in a variety of styles and types. Whether it is for home or office, there is an extinguisher to meet your needs. The most popular type of fire extinguisher is made of water. Water-based extinguishers are made to be compact and easy to use. Other types of extinguishers are available in dry chemical or powder form.
Graphite-based extinguishers contain dry graphite and smother fires made of metal. While they were originally designed to suppress magnesium fires, these extinguishers can be effective against other types of metals as well. Graphite powder is non-sticky and does not stick to fires made of lithium or flowing liquids. Because of this, they are ideal for use on all types of fires, including electrical ones.
The wet chemical in a fire extinguisher is designed to put out small or large fires. It consists of a chemical that forms a frothy blanket over the burning fuel. This chemical is effective for fires in class A, B, and C materials. However, it is not effective for fires that reach deep levels in ordinary combustibles. A fire extinguisher with a high class rating should be available in every home or business.
A fire extinguisher is typically available in buildings, but can also be found on vehicles, boats, and aircraft. Some jurisdictions require the use of fire extinguishers in certain vehicles, such as delivery vans and truck trailers. Fuel tankers, for example, are required to carry a 20-pound (9.1 kg) extinguisher. Most other vehicles can carry a five-lb extinguisher.
A water-based fire extinguisher can be used on fires involving flammable liquids, such as cooking oils. Water-based extinguishers are more expensive than those made of foam. A foam fire extinguisher will leave a residue, while a water-based extinguisher will smother an electrical fire. This is the most common type of fire extinguisher.
Dry chemical fire extinguishers should be used only in areas where the fire is confined and strong air currents can result in quick dissipation. Moreover, these agents will reduce the oxygen level in the area. They should not be used in confined spaces, where they might spread the fire and cause more damage. There are various types of extinguishers for every purpose. You can buy a fire extinguisher in the market.
CO2 extinguishers, on the other hand, have a horn that becomes extremely cold and can easily damage skin. The handle of a CO2 fire extinguisher should be squeezed to release the extinguishing agent, and the fire should be at the base of the fuel source. If the extinguisher is empty, it is time to evacuate. If you can’t get out quickly, be sure to seek help immediately.
Fire extinguishers come in three types: water mist extinguishers, dry chemical extinguishers, and foam extinguishers. Water mist extinguishers contain pressurized alkali salts in water. The mist of water from these extinguishers cools the flames and prevents them from spreading. Multipurpose dry chemical extinguishers, on the other hand, contain ammonium phosphate.
