Laboratory staff must always keep in mind the principles of "safety first, prevention first" and "who is in charge is responsible" to do a good job in the safety of laboratory electricity use.
Instructions for safe use of electricity in laboratory
1, the use of electronic instruments and equipment, should first understand its performance, according to the operating procedures. Check the electrical equipment before the experiment, and then turn on the power supply; After the experiment, turn off the instruments and equipment first, and then turn off the power supply.
2. If the electrical equipment is overheated or burned, please turn off the power immediately.
3, laboratory personnel such as leaving the laboratory or in case of sudden power failure, should turn off the power supply, especially turn off the power switch of heating appliances.
4. After the fuse of power supply or electrical equipment is blown, check the cause of the fuse first, and then replace the appropriate fuse according to the original load after troubleshooting. Do not add or replace it with other metal wires at will.
5, there can be no bare wire head in the laboratory; If exposed, a safety cover should be set; Equipment requiring grounding wire should be grounded according to regulations to prevent leakage and electric shock accidents.
6, in case of electric shock, should immediately cut off the power supply, or use insulating objects to separate the wire from the electric shock, and then implement rescue.
