1. A life was saved by a knife switch. This happened many years ago. There was a train on the fourth floor of a workshop in my factory. I was responsible for the power distribution system in that area. I installed a knife switch in a prominent location on the workshop floor. During equipment installation, a fitter accidentally touched the live sliding line and received an electric shock. He got stuck and couldn't let go, hanging in mid-air. Another worker nearby saw the knife switch and pulled it, cutting off the power. The shocked hand then released, and he fell from the height of half a floor. It turned out that he had not been electrocuted for a long time, and his landing position was good. He didn’t get injured at all! This was the second train in our factory. The first power distribution system was in a control cabinet, and very few people in the workshop knew how to cut off the power. If the same accident had occurred on the first train, the consequences could have been unimaginable. I often think that if we don’t take safety seriously, electrical engineers are always one mistake away from legal trouble. 2. Electric Shock Beauty. I once had a female electrician who was connecting a temporary power line in the distribution room. She accidentally caused a short circuit, and the arc from the high current burned her face and hands. After treatment at a military-affiliated hospital’s burn unit, she recovered well. Her face looked completely different—her skin had changed, and her original face was gone. Some said she became more beautiful than before. But ladies, would you really want to try this "beauty method"?
