Don't use water to extinguish an electrical fire
When it comes to electrical fires, it is important to remember that water is not an effective or safe method of extinguishment. Using water on an electrical fire can not only be ineffective but also extremely dangerous and lead to serious injuries or even death. Here's why you should never use water to put out an electrical fire:
Electricity and water do not mix: Water is an excellent conductor of electricity. When you pour water on an electrical fire, you are essentially providing a pathway for the electricity to travel. This means that the water will carry the electrical current, potentially increasing the size and spread of the fire. The water can also come into contact with exposed wires or damaged electrical equipment, creating a shock hazard and endangering anyone nearby.
Steam and splash back: When water is introduced to a burning electrical source, it can cause a violent steam explosion. This happens because the water instantly turns to steam due to the high temperatures, and this rapid expansion can cause a dangerous blast. Additionally, the water may also splash back at you, potentially spreading the burning material and causing burns or spreading the fire further.
It won't cool the fire: One of the principles of fire extinguishment is to remove heat, and water is usually an effective way to cool down a fire. However, in the case of electrical fires, water's cooling effect is minimal compared to the energy released by the electrical current. The electrical energy will continue to fuel the fire, and the water will have little impact on reducing the temperature.
It can make the situation worse: Using water on an electrical fire can actually make the situation worse. As mentioned earlier, water conducts electricity and can spread the fire to other areas. The steam and splash back can also spread burning material and ignite nearby flammable objects or liquids. This can quickly turn a small, contained electrical fire into a much larger and more dangerous blaze.
Increased risk of electrocution: Pouring water on an electrical fire significantly increases the risk of electrocution. The water provides a path for the electricity to travel, and if you are standing in or near the water, you could become a part of that path. This could lead to serious electrical shocks, burns, and even death. It's crucial to remember that electricity is extremely dangerous and that water only amplifies these dangers.
So, what should you use instead? There are specific types of fire extinguishers designed for electrical fires, such as a Class C or multi-purpose dry chemical extinguisher. These extinguishers use non-conductive materials to smother the fire and interrupt the chemical reaction without conducting electricity. It's important to have these extinguishers easily accessible in homes and businesses to ensure a quick response and minimize potential damage.

Cut off the electricity supply
If an appliance has caught fire, the first step is to disconnect it from its power source. Unplug the appliance if you can do so safely. If the plug itself has caught fire, or if you cannot reach the plug, go straight to the main electrical switchboard and turn off the electricity supply to the entire property. This will prevent the fire from spreading and reduce the risk of electrical shocks.
If you cannot reach the switchboard safely, or if the fire is too big to control, do not attempt to tackle it yourself. Instead, call the emergency services. In Australia, the number for the fire department and ambulance is 000.
It is important to act quickly when dealing with an electrical fire, but you should also take a moment to analyse the origin of the fire before taking action. This will help you to avoid making the situation worse. For example, water should never be used to put out an electrical fire, as water conducts electricity and could lead to electrocution.
If the fire is small, you may be able to control it by throwing baking soda onto it. The sodium bicarbonate in baking soda is a chemical also used in fire extinguishers. However, this method is not suitable for larger fires, and you should always prioritise your safety by cutting off the electricity supply and evacuating the building.

Use baking soda or a CO2 fire extinguisher
Electrical fires are serious and potentially deadly, so it's important to know how to respond. The first step is to cut off the electricity supply to the fire. If possible, unplug the appliance from the wall. If the plug itself is on fire, or you can't reach the plug, switch off the main power supply. This will prevent the fire from spreading and reduce the risk of electrical shocks.
Once you've cut off the power supply, you can focus on putting out the fire. One effective method is to use baking soda. Baking soda, or sodium bicarbonate, is a common kitchen ingredient and a powerful tool for fighting electrical fires. It's also a chemical used in Class C fire extinguishers, which are designed for electrical fires. To use baking soda to put out an electrical fire, simply throw it directly onto the flames.
Another option is to use a CO2 fire extinguisher, which is specifically designed to combat electrical fires. CO2 extinguishers are safe to use on electrical fires because they don't contain a conducting agent, so they won't conduct electricity or make the fire worse. It's important to have a CO2 fire extinguisher readily available in your home or workplace and to ensure that everyone knows where it is and how to use it.
If the fire is small, you may be able to smother it with a heavy blanket or article of clothing. However, it's important to ensure that the fabric is not combustible, as this could make the fire worse.
If the fire is too big or can't be controlled with baking soda or a CO2 extinguisher, it's crucial to call the fire department or emergency services for help.
