After the flood more hidden dangers, electricity safety should pay attention to!
Long-term immersion of electrical appliances in water will lead to the decline of insulation performance, easy to cause leakage accidents after power transmission.Therefore, when the flood enters the room, please turn off the power switch in time, so as to avoid the leakage of electricity and cause others to get electric shock accident.
1. Before entering the house after the disaster, check whether there are any fallen or exposed wires around the house. If there are any fallen or exposed wires, it should be regarded as electricity and do not touch them to avoid electric shock.
2. When entering the house, first of all, check whether the main switch of the power supply has water and whether it is wet from the appearance. Do not touch the damp wall and damp electrical equipment.(When conditions are available, use ohmmeter to check the insulation of the line, and only when qualified can power be delivered)
3. After entering the house, due to water and moisture, some electrical wires and sockets and appliances are soaked in water, which are easy to be corroded, causing the danger of leakage and short circuit.Therefore, it is necessary to carefully check the electrical facilities in the house, including electrical wires, sockets, lights, televisions, refrigerators, air conditioners, etc., to see if there is any water or moisture.
4. If the electrical wires, sockets and appliances in the house are flooded or severely affected by moisture, do not rush to use electricity. Open all doors and Windows and transfer the household appliances to a dry environment for a few days.
5. If the flooding is not serious, first send the main air switch, and then send the air switch one by one. After the power supply, please use the test pen to check whether the water pipe, electrical equipment shell, ground wire and jack in the house are live.It is recommended to purchase and install leakage protector, which can greatly reduce the risk of electric shock.
6. When using high-power electrical equipment, use your nose to smell whether there is burning smell. If there is burning smell, power should be cut off immediately.Use yellow sand and carbon dioxide extinguisher to extinguish fire. Do not use water to extinguish fire.
