Short Answer 
To safely extinguish a fire involving electrical equipment, use a Class C fire extinguisher, as it is designed for such fires and will not conduct electricity. Ensure safety measures like circuit breakers are in place, and follow the four steps for using a fire extinguisher: pull the pin, aim at the fire’s base, squeeze the handle, and sweep side to side until the fire is out.
Step 1: Choose the Right Extinguisher
When dealing with a fire involving power strips or electrical equipment, it is crucial to use a Class C fire extinguisher. This type of extinguisher is specifically designed to tackle fires caused by electrical equipment, ensuring that the chemicals used will not conduct electricity. Avoid using water, as it can lead to electrocution due to its ability to conduct electricity.
Step 2: Understand Electrical Safety Measures
To prevent electrical fires, it’s vital to be aware of safety devices like circuit breakers and fuses. These devices serve to interrupt electrical circuits if the current exceeds safe levels, thereby protecting wiring from overheating. Always ensure these safety measures are in place to mitigate the risk of fires.
Step 3: Properly Use the Fire Extinguisher
To effectively use a fire extinguisher, remember the four essential steps:
- Pull the pin to unlock the extinguisher.
- Aim the nozzle at the base of the fire.
- Squeeze the handle to release the extinguishing agent.
- Sweep the nozzle side to side until the fire is fully out.
By following these steps, you can increase your chances of safely extinguishing a small electrical fire.
