A worker in a tool workshop in a factory leads an apprentice to use a butt welder to weld knives. When installing the welding parts on the electrode clamp and aligning the position, the master verbally instructed the apprentice to support the tail of the workpiece. When the upper arm of the pneumatic clamp was pressed down, the apprentice had not pulled out the right index finger and was squeezed between the tail of the workpiece and the horn. Caused the end of the index finger to rupture and open fractures.

On the morning of February 1, 2016, an enterprise located in Wanli Street, Jinzhou New District, organized personnel to carry out die-casting processing of car engine gearbox housings. At 5:57, a worker Shi Zhengyue (male, 43 years old, from Heilongjiang Province) violated the rules and went over the protective device to check the die-casting effect while the die-casting machine was running. He was accidentally squeezed to death by the walking beam of the die-casting machine.
The severe disasters caused by mechanical accidents have shattered one family after another. Parents, wives and children are suffering in the pain of losing their loved ones.
In order for the tragedy not to repeat itself, for the lives that cannot be repeated, and to learn the lessons of the accident, we must take practical measures to avoid similar accidents.
1. Enterprises should strengthen safety management, establish safe operating procedures and require strict implementation, standardize the production environment, and provide on-the-job training for operators to operate the equipment correctly and proficiently; wear protective equipment in accordance with the regulations; dangerous when the equipment is started In the area, people are not allowed to enter or to extend their heads, hands, feet and other limbs.

2. The equipment itself must have good safety performance and necessary safety protection devices. For example: the installation location of the equipment should be easy to operate; the protective area of the machine should be equipped with a protective cover; or the installation of a stable, safe and reliable safety grating alarm device with accurate detection, the installation of a safety grating can help avoid mechanical injury accidents and avoid machine operation The work risk of workers reduces the cost of enterprise accidents.

3. Regularly check and repair the equipment and related grating protective devices to maintain good safety and solve problems in time.
4. The power supply must be cut off before maintenance, and a reminder sign must be hung up; when working in or off the machine, measures should be taken to prevent the machine from rotating; after the maintenance, the machine must be carefully inspected before trial operation.
