What You'll Learn
Firefighters disconnect the power supply
Firefighters have a challenging task when responding to electrical fires due to the unique characteristics of these blazes. Electrical fires can ignite from various sources, often stemming from issues within electrical systems, such as old or improperly installed wiring, frayed wires, loose connections, or overloaded outlets. Defective appliances, especially those with damaged cords or internal faults, can also be catalysts. The conductivity of electricity can interfere with standard firefighting methods, requiring specialized equipment and techniques.
One crucial step in tackling electrical fires is disconnecting the power supply. Firefighters work to cut off the electricity to the affected area or building to minimize the risk of electric shock and prevent the fire from spreading further. This is often done by pulling the meter, which disconnects the power source to the premises. Fire departments may have agreements with utility companies to pull the meter and provide them with the meter's location. This step is essential to ensuring the safety of both firefighters and occupants of the building.
In some cases, firefighters may work with utility electricians to take additional measures, such as defusing transformers or branch lines or shutting down an entire circuit. These steps are crucial in ensuring that the power supply is completely disconnected and that there is no risk of the fire reigniting due to hidden smoldering embers or damaged wiring when the power is restored.
The process of disconnecting the power supply is a critical aspect of firefighting strategy, especially in electrical fires. It ensures the safety of the firefighters and allows them to proceed with more effective firefighting methods without the risk of electric shock or the fire spreading through electrical systems. This step, along with the use of specialized equipment, demonstrates the unique challenges and strategies involved in combating electrical fires.

They use specialised equipment
Firefighters use specialised equipment to put out electrical fires, as they present distinct challenges. Electrical fires are caused by electrical failures or malfunctions, and the conductivity of electricity can interfere with standard firefighting methods.
Firstly, water should never be used to extinguish electrical fires, as it can lead to electrocution and damage wiring, electronics, or machinery. Firefighters will often disconnect the power supply to the building before tackling the fire, either by pulling the meter or working with utility companies to shut down circuits.
For small electrical fires, a fire extinguisher designed for electrical fires, a fire blanket, or a heavy, non-flammable material can be used to smother the flames and cut off the oxygen supply. These methods are effective for smaller fires on electrical equipment.
Class C fire extinguishers are recommended for electrical fires. They are developed using chemicals that do not conduct electricity, so they can be used even if the power is still on. Sodium bicarbonate is one agent used in these extinguishers.
In the case of electrical car fires, a recommended method is to use a crane to pick up the vehicle and drop it into a shipping container full of water.

Water is not used
Water should not be used to put out electrical fires. Electrical fires are a unique hazard that requires specialised firefighting measures. The use of water can lead to electrocution and may damage wiring, electronics, or machinery. Even when the power is off, water can still cause damage to electrical equipment.
Electrical fires involve energised electrical equipment, and the conductivity of electricity can interfere with standard firefighting methods. Firefighters must employ specialised equipment and techniques to address these fires effectively. The potential for hidden pockets of fire within walls or electrical systems also poses a challenge, as complete extinguishment may be difficult to achieve.
The recommended approach to extinguishing electrical fires is to use Class C fire extinguishers, which are designed specifically for this purpose. These extinguishers utilise chemicals that do not conduct electricity, allowing for safe use even if the power is still on. Sodium bicarbonate is one of the agents found in Class C extinguishers.
In addition to Class C fire extinguishers, fire blankets, or heavy, non-flammable materials can be used to smother the flames and deprive them of oxygen, a crucial element for combustion. This method is suitable for smaller fires on electrical equipment. However, if the fire cannot be controlled, it is crucial to prioritise safety by evacuating the premises and calling the fire service for professional assistance.
The prevention of electrical fires is also crucial. Old or improperly installed wiring, defective appliances, and overloaded circuits can all contribute to electrical fires. Regular inspections by qualified electricians can help identify potential hazards and ensure that homes or buildings meet safety provisions.

Fire blankets or non-flammable materials are used to smother flames
Firefighters face distinct challenges when tackling electrical fires. Electrical fires are often caused by issues within electrical systems, such as old or improperly installed wiring, defective appliances, or overloaded circuits. These fires pose a severe threat to life and property and require specialised firefighting methods due to the conductivity of electricity.
One effective way to extinguish small electrical fires is to use a fire blanket or a heavy, non-flammable material to smother the flames. This method involves placing the blanket over the fire, depriving it of oxygen, a crucial element for combustion. Fire blankets are designed to be fire-resistant and can effectively contain and control small fires by preventing the spread of flames and reducing the amount of oxygen available for combustion. They are typically made of woven or fibreglass fabric and can be found in homes, kitchens, laboratories, and other high-risk areas. Fire blankets are easy to use and can be wrapped around a person whose clothing is on fire to extinguish the flames quickly and safely.
When using a fire blanket, it is important to ensure that the blanket is large enough to cover the fire completely. If the fire is small and contained, one edge of the blanket can be lifted and placed behind the burning object to effectively trap the fire and deprive it of oxygen. It is crucial to act quickly and confidently when using a fire blanket, as every second counts in an emergency situation. After the fire has been extinguished, it is important to leave the blanket in place until it has cooled down completely to prevent the fire from reigniting.
In addition to fire blankets, non-flammable materials such as sand, soda ash, or sodium bicarbonate can also be used to smother electrical fires. These materials can be poured or dumped onto the fire to deprive it of oxygen and prevent its spread. However, it is important to note that while these materials can effectively extinguish flames, they may not address the underlying electrical issue that caused the fire. Therefore, it is crucial to address any electrical faults or malfunctions to prevent future fires.
