This place cannot be touched during welding

1. The accident passed by a shipyard. A young female welder was welding in the cabin. Due to the high temperature in the cabin and poor ventilation, she sweated a lot and made her work clothes and leather gloves soaked. When changing the welding rod, the welding jaws fell back due to spasm and the welding jaws fell on the neck and failed to get rid of them, causing electric shock. He died after the accident after ineffective rescue.

2. Analysis of main reasons

(1) The no-load voltage of the welding machine is higher than the safety voltage.

(2) The temperature in the cabin is high, the welder sweats a lot, the body's resistance is reduced, and the risk of electric shock increases.

(3) After electric shock, it is not discovered in time that the current passes through the human body for a long time, causing serious damage to important organs such as the heart and lungs, and the rescue is ineffective.

3. Main preventive measures
When working in the cabin, you must set up a guardian and pay attention to the welder dynamics at any time. When encountering dangerous signs, you must immediately open the gate for rescue.
