1, cut off the power supply in time.

If only a few fires are caused by electrical short circuit, you can immediately turn off the electrical power switch and cut off the power supply. If the whole circuit burns down, you must pull down the main switch and cut off the main power supply. After the power supply is cut off, the fire can be extinguished by conventional methods. If there is no fire extinguisher, it can be doused with water.

2, can't directly wash the appliance with water.

After the electrical equipment is on fire, it cannot be washed directly with water. Because water is conductive, it is easy to get an electric shock after entering live equipment, which will reduce the insulation performance of equipment and even cause equipment explosion, endangering personal safety. After the oil-filled equipment such as transformer and oil circuit breaker has a fire, water can be sprayed into mist to put out the fire. Because of the large water mist area and small water droplets, it is easy to absorb heat and vaporize, and the flame temperature drops rapidly.

3, the use of safety fire equipment.

When electrical equipment catches fire in operation, it must first cut off the power supply and then put it out. If you can't cut off the power supply quickly, you can use carbon dioxide, dry powder fire extinguishers and other equipment. When using, a sufficient safe distance must be kept, and the distance should not be less than 40 cm for the equipment below 10 kV. Be careful not to use acid, alkali or foam extinguisher, because its fire extinguishing liquid is conductive, and the person holding the fire extinguisher will get an electric shock. This potion will strongly corrode electrical equipment and is not easy to remove afterwards.

Matters needing attention in the use of electrical equipment

1. If the wire insulation outside the electrical equipment is damaged, do not continue to use it. You must wrap the insulating material before continuing to use it.

2. Pay attention to regularly check the grounding device of electrical equipment to see if there are problems such as disconnection.

3, electrical switch, fast action, and pay attention to the face, you can wear protective equipment.

4, pay attention to check the temperature of the electrical equipment shell, check can't touch with the palm, so as not to be absorbed by electricity, can't leave.

5. Don't touch the unfamiliar electrical equipment, and don't repair the equipment without authorization.
