The Importance of Using the Right Fire Fighting Equipment
Using the wrong type of fire-fighting equipment can be not only ineffective but also dangerous. For example, using water on an electrical fire can cause electrical shock, while using the wrong extinguisher on a flammable liquid fire might spread the flames further. Therefore, it’s essential to choose the correct equipment based on the type of fire you’re dealing with.
Best Fire Fighting Equipment for Class A Fires: Ordinary Combustibles
Water Fire Extinguishers
Water fire extinguishers are the most common type of extinguisher used for Class A fires. They work by cooling the fire and removing the heat, which is one of the three essential elements a fire needs to continue burning. Water extinguishers are simple to use and effective against fires involving wood, paper, and fabric.
How to Use: Aim the nozzle at the base of the flames and sweep it side to side until the fire is out.
Foam Extinguishers
Foam extinguishers can also be used on Class A fires. They work by creating a barrier between the burning material and the oxygen in the air, suffocating the fire. Foam extinguishers are versatile and can also be used on Class B fires involving flammable liquids.
How to Use: Spray the foam in a sweeping motion, covering the entire area of the fire.
Fire Blankets
Fire blankets are another effective tool for putting out Class A fires, especially if the fire is small and contained. A fire blanket is made of a flame-retardant material that can be placed over the fire to smother it.
How to Use: Place the blanket over the fire, ensuring that it completely covers the flames. Leave it in place until the fire is completely out.
Best Fire Fighting Equipment for Class B Fires: Flammable Liquids
Carbon Dioxide (CO2) Extinguishers
CO2 extinguishers are highly effective against Class B fires. They work by displacing the oxygen around the fire, essentially suffocating the flames. CO2 is also non-conductive, making these extinguishers suitable for Class C fires involving electrical equipment as well.
How to Use: Hold the nozzle with care, as it gets very cold during use. Aim at the base of the fire and sweep the nozzle from side to side.
Dry Chemical Extinguishers
Dry chemical extinguishers, particularly those labeled for use on Class B and C fires, are very effective. They contain a powder that interrupts the chemical reaction taking place in the fire, effectively stopping it.
How to Use: Aim at the base of the flames and sweep from side to side until the fire is out.
Foam Extinguishers
As mentioned earlier, foam extinguishers are versatile and can be used on both Class A and B fires. When used on a Class B fire, the foam forms a blanket over the surface of the flammable liquid, preventing the fire from accessing more oxygen.
How to Use: Spray the foam in a sweeping motion, ensuring that the entire surface of the liquid is covered.
Best Fire Fighting Equipment for Class C Fires: Electrical Equipment
Carbon Dioxide (CO2) Extinguishers
CO2 extinguishers are a top choice for electrical fires. They do not leave any residue, which is crucial when dealing with sensitive electrical equipment. The CO2 displaces oxygen around the fire, cutting off the fuel source.
How to Use: Point the nozzle at the base of the flames and move it side to side. Be cautious, as the nozzle gets extremely cold during use.
Dry Chemical Extinguishers
Dry chemical extinguishers are also suitable for Class C fires. They can stop the fire by interrupting the chemical reaction and cutting off the fire’s fuel.
How to Use: Aim at the base of the fire and sweep side to side until the fire is completely extinguished.
Fire Blankets
For smaller electrical fires, especially those involving a single device, a fire blanket can be effective. It’s crucial, however, to turn off the electricity if possible before attempting to use a blanket.
How to Use: Carefully place the blanket over the fire, ensuring it covers the flames fully. Do not remove the blanket until the fire is entirely out.
Best Fire Fighting Equipment for Class D Fires: Combustible Metals
Class D Powder Extinguishers
Class D fires are unique and require special extinguishing agents. Class D powder extinguishers are designed specifically for combustible metals like magnesium, titanium, and sodium. These extinguishers contain a powder that can smother the fire and absorb the heat.
How to Use: Spray the powder directly onto the burning metal. It’s essential to apply a thick layer to completely cover the fire.
Sand
In some cases, simple sand can be an effective extinguishing agent for Class D fires. Sand can absorb heat and smother the flames, preventing the fire from spreading.
How to Use: Pour sand over the fire to completely cover it. Make sure to use enough sand to fully smother the flames.
Best Fire Fighting Equipment for Class K Fires: Cooking Oils and Fats
Wet Chemical Extinguishers
Wet chemical extinguishers are specifically designed for Class K fires, which are common in kitchens. These extinguishers contain a solution that cools the fire and reacts with the cooking oil to form a soapy layer that seals the surface, preventing re-ignition.
How to Use: Aim the nozzle at the base of the flames and apply the solution in a sweeping motion. Ensure the entire surface of the oil is covered.
Fire Blankets
Fire blankets are also effective against Class K fires, particularly for small stovetop fires. They can quickly smother the flames by cutting off the oxygen supply.
How to Use: Carefully place the blanket over the fire, making sure it covers the entire pan or pot. Leave the blanket in place until the fire is completely out.
Other Essential Fire Fighting Tools and Equipment
In addition to fire extinguishers and blankets, there are other tools and equipment that can help in fire emergencies. Knowing when and how to use these can make a big difference in controlling a fire before it gets out of hand.
Fire Hose Reels
Fire hose reels are a common feature in many commercial buildings. They provide a continuous supply of water, which can be crucial for tackling larger fires, particularly Class A fires.
How to Use: Unwind the hose and aim the nozzle at the base of the fire. Turn on the water and move the nozzle in a sweeping motion to cover the fire.
Fire Buckets
Fire buckets filled with water or sand can be useful in certain situations. They are often placed in strategic locations as a quick and easy means of fire control.
