Risk grade of occupational hazards

Occupational disease refers to the long-term effects of chemical, physical and biological harmful factors in the occupational environment on the health of workers. In order to better protect the health of workers, China has formulated occupational disease risk grades. Let's have a brief look.

I. Classification of Occupational Hazards

Occupational hazard factors mainly include chemical factors, physical factors, biological factors and other factors. Among them, chemical factors include toxic substances, harmful substances and dangerous goods; Physical factors include noise, vibration and radiation. Biological factors include pathogens, viruses, etc. Other factors include dust, high temperature, low temperature, high pressure and low pressure.

Two. Classification of risk grades of occupational hazards

The risk levels of occupational hazards are mainly divided into five levels, namely, particularly significant, significant, large, general and harmless.

1. Extremely serious hazard: refers to the occupational hazard factors with very serious degree and scope, which can cause serious harm to the human body and have very serious consequences or are difficult to recover.

2. Major hazard: refers to the occupational hazard factors with large degree and scope, which can cause serious harm to human body and cause serious consequences or are difficult to recover.

3. Great harm: refers to the occupational hazard factors that have a large degree and scope, can cause certain harm to the human body, and cause serious consequences or are difficult to recover.

4. General hazard: refers to the occupational hazard factors with a general degree and scope, which can cause a certain degree of harm to the human body and light consequences.

5. Harmless: refers to the occupational hazard factors with low concentration or intensity in the occupational environment, which will not cause harm to human body.

Three. Importance of Risk Grade of Occupational Hazards

The classification of occupational hazard risk grades is to better protect workers' health and prevent occupational diseases. In the workplace, enterprises should take corresponding protective measures according to the risk level of occupational hazards to reduce the concentration and intensity of occupational hazards, so as to protect the health of workers.
