Do you understand the root cause of machine safety accidents?

It is very necessary for production units to pay attention to safety accidents, because once a safety accident occurs, it may have a serious impact on the life safety and health of personnel, the integrity of equipment and facilities, and the normal progress of production activities. According to the definition of relevant standards (such as GB/T 6441), there are up to 20 safety accident categories in production activities, of which mechanical injury accidents and electric shock accidents are the most common safety accident categories, and they are also the types of accidents that production units need to pay special attention to and prevent when using machines for production activities.

Definition of production safety accident

According to the definition of "Interpretation of the Production Safety Law of the People's Republic of China", "production safety accident" refers to the sudden occurrence of a production and business entity in the production and business activities (including activities related to production and business), which harms personal safety and health, damages equipment and facilities or causes direct economic losses, resulting in the temporary suspension or permanent termination of production and business activities.

According to the safety theory, the causes of production safety accidents can be mainly attributed to four aspects: unsafe behavior of people, unsafe state of things, management defects and unsafe environmental factors. In the production of factory machines, the causes of safety accidents mainly focus on the unsafe behavior of people and the unsafe state of things.

First: people's unsafe behavior

Human unsafe behavior is one of the important reasons leading to factory machine safety accidents. For example, operator negligence, improper operation, violation of operating procedures, lack of safety awareness and training and other behaviors may lead to the occurrence of safety accidents. Therefore, to strengthen the safety training of operators, improve their safety awareness, strict implementation of operating procedures and other measures are essential to prevent safety accidents.

Second: the unsafe state of the object

The unsafe state of the material is another important cause of factory machine safety accidents. The machine itself has design defects, manufacturing defects, aging, wear and other problems, lack of safety protection devices or imperfect safety protection devices may lead to safety accidents. Therefore, measures such as ensuring the safety of machinery and equipment, regular inspection and maintenance of machinery and equipment, and timely repair of safety hazards are essential to prevent safety accidents.

Eliminating unsafe behavior of people VS eliminating unsafe state of things

In the production process, the interaction between human and machine is inevitable, and the implementation of production, debugging, maintenance and other tasks also increases the risk of safety accidents. In order to ensure the safety of the production process, effective safety precautions must be taken to eliminate the unsafe behavior of people and the unsafe state of things, so as to prevent the occurrence of accidents to the greatest extent.

Domestic regulatory requirements

In the Production Safety Law of the People's Republic of China, there are a number of provisions on the elimination of unsafe behavior of people and the elimination of unsafe conditions of things, such as: "Article 29 When a production or business entity adopts a new process, new technology, new material or uses new equipment, it must understand and master its safety and technical characteristics, take effective safety protection measures, and conduct special education and training on production safety for its employees." "Article 36 The design, manufacture, installation, use, testing, maintenance, transformation and scrapping of safety equipment shall conform to national standards or industry standards, and production and business units must carry out regular maintenance and maintenance of safety equipment, and regularly test to ensure normal operation." Maintenance, maintenance, testing should be recorded, and signed by the relevant personnel."

To sum up, the elimination of unsafe behavior of people and the elimination of unsafe state of things should at least be carried out at the same time, complement each other, and jointly ensure the smooth progress of safe production, but from the relevant legal requirements and safety production management practice, the elimination of unsafe state of things is the premise and basis for effectively avoiding machine safety accidents, and is also the preferred measure. Through regular inspection, maintenance of equipment, installation of safety protection devices, equipment updates and other measures, can effectively reduce the impact of equipment itself on safety production, improve workplace safety.
