Fire extinguishers for electrical fire or electrical appliances are always at risk of catching on fire. Knowing the types of fire extinguisher and how to use them is vital for fire safety. What type of fire extinguisher to use in the event of a fire depends on what material is burning. In the case of an electrical fire, one should use a fire extinguisher associated with class C fires.
A class C fire refers to a fire involving energised electrical equipment, that is, equipment that is connected to a power source. These fires can be especially dangerous as they have a steady supply of fuel coming to them. They can even turn into yet another type of fire if the electrical fire spreads to other places in the room.
Classes of Fire
First, let’s go over the classes of fire and what they refer to.
Class A: for fires involving organic materials like wood, paper, or fabric
Class B: for fires involving flammable liquids (petrol, diesel) and flammable gases (propane, methane)
Class C: for fires involving energized electrical equipment
Class D: for fires involving burning metals
Class F: for fires involving cooking oils (such as those found in deep-fat fryers)
Fires Involving Electrical Equipment or Fire Extinguishers For Electrical Fires
Electrical fires can happen due to a number of causes:
- Bad wiring
- Overcharged devices
- A circuit that has shorted
- Damaged power cords
- Overloaded power outlets
The thing about electrical fires is that they must be extinguished with a solution that isn’t conductive. If water fire extinguishers or foam extinguishers are used, there will be a significant risk of electrocution, which can be fatal.
What Type of Fire Extinguisher to Use
The best type of fire extinguisher to use for an electrical fire would either be a carbon dioxide extinguisher or a dry powder extinguisher.
The dry powder extinguisher contains substances like phosphates and potassium, which are non-conductive and very effective at putting out fires.
The carbon dioxide fire extinguisher contains, as the name suggests, CO2. This primary ingredient is excellent for putting out fires because it depletes an electrical fire of oxygen as well as takes away the fire’s heat (carbon dioxide is very cold when discharged from the extinguisher).
How To Use A Fire Extinguisher
You can use a fire extinguisher by remembering the”PASS” method.
The PASS method goes like this: 1. “P” for pulling the pin, 2. “A” aim at the fire, 3. “S” squeeze the handle, and 4. “S” sweep the nozzle from side to side.
If you know the PASS method, you know how to use any type of fire extinguisher. It’s easy to memorize and a perfect addition to your fire safety toolbox.
Fire Safety Tips For Fire extinguishers for electrical fires
As with any fire safety device, an extinguisher will require regular maintenance to keep it working properly.
Be sure to get any fire extinguishers that you own inspected as regularly as it is recommended to do so. Additionally, after using a fire extinguisher, ensure that you get it replaced or recharged, as you don’t want to be left with an empty extinguisher in the event of another fire.
