Types Of Fire Extinguishers And Their Uses Chart
Fire is an ever-present danger that can cause significant damage to property and even loss of life. This is why it is essential to have appropriate fire safety measures in place, including the proper use of fire extinguishers. However, not all fires are the same, and using the wrong type of fire extinguisher can be ineffective, or even dangerous. In this article, we will discuss the different types of fire extinguishers and their uses.
Class A Fire Extinguishers
Class A fires involve ordinary combustibles such as wood, paper, or cloth. Class A fire extinguishers are suitable for use on these types of fires. They work by cooling the fire and removing heat from the fuel source. These extinguishers typically contain water, foam, or powder.
Class B Fire Extinguishers
Class B fires involve flammable liquids such as gasoline, oil, or grease. Class B fire extinguishers are suitable for use on these types of fires. They work by smothering the fire and preventing oxygen from reaching the fuel source. These extinguishers typically contain foam or powder.
Class C Fire Extinguishers
Class C fires involve electrical equipment such as computers, appliances, or motors. Class C fire extinguishers are suitable for use on these types of fires. They work by interrupting the electrical current and extinguishing the fire. These extinguishers typically contain carbon dioxide or dry powder.
Class D Fire Extinguishers
Class D fires involve combustible metals such as sodium, magnesium, or titanium. Class D fire extinguishers are suitable for use on these types of fires. They work by smothering the fire and preventing oxygen from reaching the fuel source. These extinguishers typically contain dry powder.
Class K Fire Extinguishers
Class K fires involve cooking oils and fats, which can quickly spread and cause significant damage. Class K fire extinguishers are suitable for use on these types of fires. They work by chemically reacting with the cooking oil or fat, and forming a soap-like substance that extinguishes the fire. These extinguishers typically contain wet chemical agents.
Water Mist Fire Extinguishers
Water mist fire extinguishers are suitable for use on Class A and Class C fires. They work by spraying a fine mist of water, which cools the fire and removes heat from the fuel source. These extinguishers are suitable for use in areas where there is a risk of electrical shock.
Carbon Dioxide Fire Extinguishers
Carbon dioxide fire extinguishers are suitable for use on Class B and Class C fires. They work by displacing the oxygen from the air, which extinguishes the fire. These extinguishers are suitable for use in areas where there are sensitive electronic equipment or flammable liquids.
Dry Powder Fire Extinguishers
Dry powder fire extinguishers are suitable for use on Class A, Class B, and Class D fires. They work by smothering the fire and preventing oxygen from reaching the fuel source. These extinguishers are suitable for use in areas where there are combustible metals.
Wet Chemical Fire Extinguishers
Wet chemical fire extinguishers are suitable for use on Class K fires. They work by chemically reacting with the cooking oil or fat, and forming a soap-like substance that extinguishes the fire. These extinguishers are suitable for use in commercial kitchens.
Conclusion
It is essential to choose the appropriate fire extinguisher for the type of fire that you are dealing with. Using the wrong type of fire extinguisher can be ineffective, or even dangerous. By understanding the different types of fire extinguishers and their uses, you can ensure that you are prepared to deal with a fire if it arises.
