Which fire extinguisher is used for electrical fire?

The five types of fire extinguishers that are used depending on the type of fire An electrical fire is a type of fire that is caused by faulty or damaged electrical equipment, wiring, or outlets. Electrical fires can be very dangerous and difficult to extinguish, as they can spread quickly and create shock hazards. Therefore, it is important to know which fire extinguisher is suitable for electrical fire and how to use it safely and effectively.

Classifications

Fire extinguishers are classified according to the types of fires they can put out. There are five main classes of fire extinguishers: A, B, C, D, and K. Each class corresponds to a different kind of fuel that feeds the fire. For example, class A fire extinguishers are designed for ordinary combustible materials such as wood, paper, or cloth; class B fire extinguishers are for flammable liquids such as gasoline, oil, or paint; class D fire extinguishers are for combustible metals such as magnesium, titanium, or sodium; and class K fire extinguishers are for cooking oils and fats.

Class C fire extinguishers are the ones that are used for electrical fires. These fire extinguishers contain non-conductive agents that do not conduct electricity and can safely extinguish fires involving energized electrical equipment. The most common types of class C fire extinguishers are carbon dioxide (CO2) and dry chemical. CO2 fire extinguishers work by displacing oxygen and smothering the fire. Dry chemical fire extinguishers work by interrupting the chemical reaction of the fire and creating a barrier between the fuel and the oxygen.

Extinguisher Usage Tips

Class C Fire Extinguisher

To use a class C fire extinguisher for an electrical fire, follow these steps:

  1. Before attempting to fight the fire, make sure that the power source is turned off or disconnected if possible. This will reduce the risk of electrocution and reignition.
  2. Check the label and the pressure gauge of the fire extinguisher to make sure that it is suitable for class C fires and that it is fully charged.
  3. Stand at a safe distance from the fire, usually about 6 to 10 feet away.
  4. Pull the pin at the top of the fire extinguisher to break the seal.
  5. Aim the nozzle or hose at the base of the fire, where the fuel source is.
  6. Squeeze the lever or trigger to release the extinguishing agent.
  7. Sweep the nozzle or hose from side to side until the fire is out.
  8. Watch for any signs of re-ignition and repeat if necessary.

Some fire extinguishers are multipurpose and can be used for more than one class of fire. For example, some dry chemical fire extinguishers are labeled as ABC, meaning that they can be used for class A, B, and C fires. However, not all fire extinguishers are compatible with all types of fires. For example, water or foam fire extinguishers should never be used for electrical fires, as they can conduct electricity and cause shock or electrocution. Therefore, it is important to read the label carefully and choose the right fire extinguisher for the situation.

Fire extinguishers are essential tools for preventing and controlling small fires in emergencies. However, they are not intended for large or out-of-control fires that require professional intervention. If you encounter an electrical fire that is beyond your ability or capacity to handle, do not hesitate to call 911 or your local emergency number and evacuate the area immediately. Remember that your safety is always the priority.
