Fires can be devastating and cause immense damage, injury, and even loss of life. It is essential to have a proper understanding of the different types of fires and the right type of extinguisher to use to ensure safety and prevent the spread of fires.
There are five different classes of fires, and each requires a specific type of extinguisher to put them out safely.
Class A Fire
Class A fires are common and involve ordinary combustibles like wood, paper, and cloth. Water and foam-based extinguishers are effective for this type of fire. Water-based extinguishers are the best option for Class A fires as they cool the burning material and remove the heat source. A Class A fire extinguisher is typically labeled with a green triangle and can be used on fires that involve organic materials.
Class B Fire
Class B fires involve flammable liquids, such as gasoline, oil, and solvents. These fires are prevalent in garages and industrial settings, and it is important to use the correct extinguisher as water can worsen the situation. A dry chemical extinguisher or CO2 extinguisher works best to suffocate the fire by removing oxygen while dry chemical extinguishers work by smothering the flames with a dry powder.
Class C Fire
Class C fires involve electrical equipment, such as computers, wiring, and appliances. It is essential to turn off the power source before attempting to put out the fire. CO2 and dry chemical extinguishers are appropriate for Class C fires, as they do not conduct electricity. These types of fires are particularly dangerous because of the risk of electrocution. The CO2 extinguisher will suffocate the flames, while the dry chemical extinguisher will smother the flames.
Class D Fire
Class D fires involve combustible metals such as sodium, titanium, and magnesium. These types of fires are common in industrial settings and require a special dry powder extinguisher to put them out. Water, foam, and carbon dioxide extinguishers are not suitable for Class D fires. Class D fire extinguishers use a dry powder agent to smother the flames and prevent re-ignition.
Class K Fire
Class K fires occur in kitchens and involve cooking oils, fats, and grease. Wet chemical extinguishers are suitable for Class K fires and work by cooling the flames and creating a barrier between the fire and fuel source.
It is crucial to choose the right extinguisher for the specific type of fire to avoid worsening the situation or putting oneself in danger. Moreover, it is essential to receive proper training in using fire extinguishers.
Understanding the different types of fires and the appropriate extinguisher to use is crucial to prevent the spread of fires and ensure safety. It is important to have multiple types of extinguishers on hand and receive proper training in their use. Remember, if a fire is out of control or if there is any doubt about the ability to put it out safely, it is always best to call the fire department and evacuate the premises.
