The safety device on the production equipment in the workshop is the key line of defense to isolate the operators from the production hazards. It plays an important role in preventing production casualties and cannot be dismantled, misappropriated or discarded at will.

However, some companies ignore safety and let safety devices work "ill"! Some employees even "don't want life", ignore safety devices and work in violation of regulations without authorization! Finally brings a lesson of "blood"! The following accident caused the death of a 21-year-old employee on the spot!

Regarding the accident

From 20 o’clock on the day of the incident, employees Lu and Zhou in the workshop of a packaging company in Kunshan started to work and operated 1# blister machine for production. Zhou was responsible for the collection of materials, and Lu was responsible for the maintenance of equipment, the abnormal handling of products, and the handling of materials. Management etc.

At around 21:10, Zhou found that the product had abnormal quality and went to the middle section of 1# blister machine to check and found that Lu was dealing with the abnormal quality.

 

 

 

At around 21:30, Zhou found blood on the product when he was cutting the 1# blister machine.

Immediately, Zhou ran to the middle section of the 1# blister machine and found that the technician Lu was lying inside the 1# blister machine with his head squeezed. After that, 120 first-aid personnel confirmed that Lu was dead.

Accident site survey

After investigation, it was found that the safety protection sensing device on the safety door of the incident equipment was artificially shielded (the two contact sensing points on the inner and upper side were abnormally pasted by stainless steel sheets), which means that the safety door of 1# blister machine will also be opened. Continue to operate, leaving room for people to enter the equipment that is being produced.

 

 

The direct cause of the accident

1# The safety door safety protection induction device of the blister machine is artificially shielded, so that the equipment can continue to operate after the safety door is opened. Lu enters the equipment to handle the abnormality while the equipment is running. Cause an accident.

 

 

 

Nature of the accident

After investigation, the accident investigation team determined that this mechanical injury accident was a production safety liability accident caused by employees' illegal operations, entering into the equipment during the operation of the equipment, and the failure of the safety protection device.

Of course, in the accident, apart from a certain person in Lu who worked illegally, the company involved in the incident had obvious loopholes in the management of safety protection devices. The investigation and management of hidden accidents was not in place, and the failure to eliminate safety hazards in time was also an important cause of the accident !

Enterprises must pay close attention to employee safety training, and more importantly, check and manage hidden dangers. They must not use employee life and production safety as a trifling matter!

Similar accidents happen from time to time. In the following accident, the man opened the safety door of the processing center and was involved in death instantly!

 

 

Accident prevention

So, what are the safety protection technical measures for mechanical equipment?

How can the safety device really play its protective role?

I've arranged it for you!

1. Types of mechanical damage

1. Strangulation: The exposed pulleys, gears, and screws directly twist clothes, sleeves and trousers, gloves, aprons, and long hair into the machine, causing personal injury.

2. Object strikes: rotating machine parts, parts that are not firmly stuck, and workpieces flying out during striking operations cause personal injury.

3. Crushing: injuries caused by punches, presses, shears, and forging hammers.

4. Smashing: Injury caused by falling parts and lifting objects at a high place.

5. Crushing injury: injury caused by squeezing the human body or a part of the human body.

6. Burns: Damage to the human body caused by high-temperature objects. Such as iron scraps, welding slag, solution and other high-temperature objects harm the human body.

7. Puncture cuts: injury to the human body caused by sharp objects.
