Types Of Fire Extinguishers And Fires They Put Out

Blog

Putting out fires before they spread helps save lives and property, and that's where portable fire extinguishers come in handy. They're light to lift and carry, easy to operate, and don't take up much space in a home or office. Each fire extinguisher has a fire category it handles, making selection challenging for many. Before choosing a fire extinguisher, check the likely cause of the fire and the size of your establishment, as these will determine the type and size of the fire extinguisher you need. Here are fire extinguisher types and the fires they put out.

Water Fire Extinguishers   

Portable water fire extinguishers are simple and prevalent in many homes and offices. They put out the fire by soaking the materials, thereby absorbing heat and cooling other flammable objects around the fire. They're preferred by many since they're easy to handle and safe as they contain only water. They're perfect for Class A fires that involve carbon-based materials like wood, paper, and textiles.    

Foam Fire Extinguishers 

These fire extinguishers work similarly to water extinguishers, the only exception being the Aqueous Film Forming Foam (AFFF) they produce. They're perfect for Class B fires caused by flammable liquids like petrol, paraffin, oil, or diesel. They also work on Class A fires, and that's why you'll find them in offices, warehouses, hotels, and garages. Foam fire extinguishers work by cooling the fire and covering the flames and other materials with the foam, preventing them from reigniting. Moreover, they do not pose any health risks. 

Carbon Dioxide Extinguishers 

These fire extinguishers contain pressurized carbon dioxide, an effective fire suppressant. They don't leave any residue and are perfect for electrical fires, making them suited for office use. They're also suitable for Class B fires. They work by suffocating fire (cutting the oxygen supply, which is crucial for combustion) and preventing it from spreading. However, the extinguishers get cold when discharging, so they have frost-free swivel horns to protect users. They also don't damage the electronics and are residue-free. 

Dry Powder Extinguishers

These fire extinguishers are perfect for Class C fires caused by combustible gasses and Class A and B. The dry powder forms a crust around the burning object suffocating the fire in the process. It's always best to use this extinguisher in a well-ventilated space. 

Conclusion

Fire extinguishers are perfect for putting out fires instantly to avoid further damage. Choosing the suitable fire extinguisher depends on where you'll be using it and the likely class of fire to break out at your premises. Many places are suited for Class A, B, and C.
