Welding accidents

Welding is a high-risk job involving a variety of potential hazards, including electric shock, fire, explosion, radiation, poisoning and burns. The following is an analysis of a welding accident.

A young female welder at a shipyard was welding in a cabin. Due to the high temperature in the cabin and poor ventilation, she sweated a lot and her work clothes and gloves were soaked. When she changed the welding rod, she touched the welding clamp and suffered an electric shock. When she was shocked, she fell backwards due to spasms, but the welding clamp accidentally fell on her neck. In the end, rescue was ineffective and she died.

Main causes of the accident

(1) The no-load voltage of the welding machine was high, exceeding the safety voltage;

(2) The temperature in the cabin was high, the welder sweated a lot, the body resistance decreased, and the risk of electric shock increased;

(3) After the electric shock, she failed to find it in time and seek help in time. The current passed through the human body for a long time, and important organs such as the heart and lungs were seriously damaged, and rescue was ineffective.

How to prevent accidents?

(1) When working in the cabin, a ventilation device must be installed to allow air convection to avoid excessive internal temperature;

(2) When working in the cabin, there must be a supervisor who pays attention to the welder's working status at all times and immediately pulls the switch to rescue people when there are signs of danger.
