[Jianshe Tong] another accident: the hand-held grinding machine was misoperated and hit an employee in the chest


Jianjiantong media ID: jianzhong001 recently, another cutting piece accident happened

.

The grinder without protective cover is a rogue

.

The grinder is one of the most commonly used auxiliary equipment inside and outside the industry and is widely used in factories

.

Grinding wheel is brittle, high speed, frequent use, slight negligence, very easy to hurt people

.

Whether the installation position of grinding wheel is reasonable, whether it meets the requirements, whether its use method is correct, whether it meets the safety operation regulations, these problems are directly related to the personal safety of every employee

.

Once a link goes wrong, it may cause serious personal injury accidents, so we must pay attention to it in practical use! 01 cutting machine cuts artery, bleeding too much, death! It is understood that men in the use of hand-held grinding wheel cutting machine, did not notice that the switch of the cutting machine is open

.

After the man plugged in the power, the cutting machine suddenly jumped up and cut the man’s thigh

.

At first, the man thought it was ok, so he didn’t go to the hospital in time

.

Now the initial suspicion is due to excessive blood loss, died! 02 grinding wheel out of control, face split in two! One day, worker Wang went to the construction site as usual, came to his familiar grinding wheel to polish products

.

Unexpectedly, an unexpected situation happened

.

The grinding wheel that is rapidly rotating suddenly breaks, and the crack with great inertia is embedded in Wang’s face

.

The next scene is even more miserable

.

The crack of grinding wheel has been nailed on Wang’s face like a pile

.

It directly penetrated into his bilateral eyes and embedded into his brain, almost splitting his face into two parts

.

After the workers found him, they immediately called 120 and sent him to a nearby hospital

.

After simple debridement, he was transferred to the Second Affiliated Hospital of Medical College of Zhejiang University, which has more treatment experience

.

According to the chief physician, Wang had been in shock when he came

.

Although his whole face was covered with gauze, he could still see the blood and blood oozing out from the wound

.

The foreign body was inserted into the left eye until the diameter of the right eye was about 10 cm, and the eyeball was displaced and protruded

.

03 improper operation of grinder, workers suffered caesarean section! Grinding wheel machine is often used in the construction site, but it is easy to be ignored! But the accident is often a major event, an insignificant shield, may be able to protect life! Have not seen a similar accident, do not know the importance of protection, hope this kind of accident case can cause attention! 04 grinding wheel hit the worker in the neck and died on the spot! At a construction site in Shenzhen, when a worker used a grinder to cut steel wire rope, the grinding wheel was broken and the flying debris hit the worker’s neck, causing the worker to die on the spot! Preliminary analysis on the causes of similar grinder accidents left at the accident site: 1

.

The grinder was not equipped with a protective cover; 2

.

The workers involved did not check the safety of the grinder before use

.

05 wheel burst, hit the head, died on the spot! When a equipment supplier was debugging the grinding head of a turning grinder, the grinding wheel burst, and the flying grinding wheel hit Liu’s head, causing Liu’s death on the spot! Cause analysis of the accident: 1

.

The operator failed to operate according to the requirements of the operation procedure during the test run, violating the test run operation procedures

.

2

.

The designed maximum working speed of the grinding wheel is 930 rpm

.

In case of an accident, the speed of the grinding wheel is 1848.9 rpm

.

When the speed exceeds the breaking limit speed of the grinding wheel, the grinding wheel is broken due to serious overspeed

.

3

.

The manufacturing of grinding wheel protective cover can not meet the jb4029-2000 “technical requirements for safety protection of grinding wheel protective cover of grinding machine”, which has lost its due protective effect; 4

.

The person in charge of shift operation failed to fulfill the obligation of informing and did not strictly implement the test specifications

.

5

.

Liu’s lack of understanding of technical standards and safety awareness is an act of bravado; how to avoid similar injuries? The following precautions are very important: 1

.

The grinder with protective cover must be used; 2

.

The size of grinding wheel must match; 3

.

The grinding wheel must be in good condition without damage and crack; 4

.

The protective glasses and safety helmet must be worn correctly during operation; 5

.

The operator must not be in the tangent direction of grinding wheel; 6

.

The grinding direction of grinding machine during operation is strictly prohibited to face the surrounding workers and all inflammable and explosive hazards 7

.

When using the hand-held grinder, remember not to use too much force, and use it slowly and evenly, so as to avoid the breakage of the grinding wheel

.

Don’t think that there is no risk in grinding operation, all workers must be clear and carefully treat the existing risks! Before using the grinder, we should learn how to eliminate, reduce and prevent the risk from turning into injury

.

Remember, as long as we operate in strict accordance with the rules and regulations, strictly abide by the safety operation procedures, so that: people machine environment, are in the best state, then the accident of the grinder will be greatly reduced! If it is found that the grinder is not operated in accordance with the safety behavior in the workplace, the corresponding operators should be educated or guided; if it is found that in the workplace, the accident of the grinder will be greatly reduced If there are other workers within 3 meters around your grinding operation site, they should also be equipped with the same labor protection articles as you
