One day, while employee A was working in the workshop, the light bulb inside suddenly went out. Thinking the bulb was broken, A stepped on an iron stool to replace it. While replacing the light bulb, Person A accidentally touched the metal part of the lamp socket and got an electric shock. Employee B noticed this and promptly turned off the light switch, causing Employee A to fall off the stool. Employee B quickly came over to check and found that Employee A had a head injury with bleeding, was unconscious, and the amount of blood loss from the head was not significant. Everyone discusses: 1. How to provide first aid to Employee A on the spot? 2. In this case, what are Employee A’s incorrect actions? 3. What lessons should we learn from this case?
1. First, determine whether Party A’s breathing is normal; if breathing has stopped or is weak, cardiopulmonary resuscitation can be performed. Of course, you should call the police first. If it’s just a minor head injury from a collision, it can be simply bandaged and the person taken to the medical room. 2. When replacing a light bulb, the power must not be turned off, insulating gloves must be worn, and stools are also conductive materials. 3. When working on live electrical circuits, the power must be turned off and insulating protective clothing must be worn
Employee A’s incorrect actions: 1. Failure to check for electricity. 2. Installing electrical appliances by non-electricians. 3. Use an iron stool. 4. Parts in contact with metal.
The incorrect aspects in Person A’s approach: 1. Whether Person A is a qualified electrical professional. 2. The power supply should be turned off first. 3. It is necessary to check whether the wires are live. 4. One should not stand on metal stools; insulated ones should be used instead
