Never use water to put out electrical fires
Firefighters must be suspicious of electrical fires and be aware of their surroundings. They must determine the environmental risk and any possible hazards to civilians. Electrical fires are extremely dangerous and can be started by severe weather, accidents, poor connections, or aging infrastructure.
When dealing with electrical fires, it is important to remember to never use water to put them out. Water is a conductor of electricity, and using it to extinguish an electrical fire can lead to electrocution. Not only will water not put out the fire, but it can also cause the fire to spread by conducting electricity to other areas, especially if there are flammable materials in the vicinity, such as curtains or fabric furniture.
The odds of knowing the purity of the water are rare, and even if it were pure, water evaporates at 100°C (212°F) and will instantly boil away. This rapid boiling and bubbling will cause the flaming grease or oil to be thrown around, expanding the surface area of the fire and making it stronger.
If you know what device is causing the electrical fire and it is safe to do so, unplug it to separate the fire from its fuel source. Small electrical fires can be put out with baking soda or by smothering them with a heavy blanket to remove the oxygen source. It is important to only use these methods if the fire is small and the materials used will effectively separate the flame from its fuel or oxygen source.
For larger electrical fires, it is recommended to use CO2 or dry chemical extinguishers. If these are not available, a narrow fog stream can be used as a last resort. If the fire cannot be controlled, it is crucial to evacuate the building and call for emergency services.

Fire prevention strategies
Firstly, it is important to understand the common causes of electrical fires. These fires can be caused by a range of issues, such as faulty wiring, overloaded appliances, or aging infrastructure. Severe weather conditions, like hurricanes or storms, can also cause electrical fires, so it is important to be cautious during such events.
One key strategy is to ensure regular electrical inspections by qualified electricians. They can identify potential hazards, such as poor wiring or overloaded circuits, and recommend necessary upgrades, like AFCI protection, which detects electrical hazards that standard breakers might not. It is also important to pay attention to warning signs, such as flickering lights, buzzing sounds, frequently blown fuses, or discoloured outlets, and address them promptly.
Another strategy is to practice safe electrical usage. This includes using light bulbs with the correct wattage, installing child-proof safety measures to prevent electrocution, and avoiding the overuse of extension cords, especially with heating or cooling units. It is also important to use electrical devices properly and avoid using any that show signs of wear or fraying.
Additionally, it is crucial to have the right fire safety equipment and know how to use it. Ensure you have a C-rated or ABC-rated fire extinguisher, which is suitable for electrical fires, and learn how to operate it. Fire blankets can also be used to smother small electrical fires.
By implementing these fire prevention strategies, the risk of electrical fires can be significantly reduced, helping to protect both property and lives.

Fire extinguishers and fire blankets
Fire extinguishers are the primary tool used by firefighters to combat electrical fires. It is important to use the correct type of fire extinguisher, which, in the case of electrical fires, is a C-rated or ABC-rated extinguisher. These extinguishers are specifically designed to fight fires involving electrical equipment and will be clearly labelled. If you do not have a C-rated extinguisher, it is advised to only use an A- or B-rated extinguisher if you are certain that the power source has been cut off, as these rely on conductive materials to put out fires.
When using a fire extinguisher, always ensure that you are standing a safe distance away from the fire and follow the instructions on the extinguisher. Aim the spray at the base of the fire, where the flames meet the fuel source, and sweep back and forth until the fire is out. It is important to remember that fire extinguishers have a limited range, so keep a safe distance and do not put yourself at risk.
Fire blankets, often made from thick, fire-resistant materials, are another effective tool for fighting electrical fires. They work by cutting off the oxygen supply to the fire, which smothers the flames and prevents it from spreading. Fire blankets are particularly useful for small fires and can be used to extinguish flames on a person's body or to cover flammable liquids that have ignited. When using a fire blanket, ensure that you are able to do so safely, without putting yourself at risk. Place the blanket over the fire, making sure to cover it completely, and then slowly pull the blanket towards you, ensuring the fire is fully extinguished.
In addition to fire extinguishers and fire blankets, it is important to take preventative measures to reduce the risk of electrical fires. This includes regularly inspecting electrical devices for wear and tear, using light bulbs with the recommended wattage, and not overloading power outlets. It is also crucial to pay attention to warning signs, such as flickering lights or frequently blown fuses, and to call an electrician if you suspect any electrical issues.
