How does the occupational disease network identify the occupational hazard factors in the workplace?

At present, the situation of occupational health prevention and control is grim, and occupational hazard identification plays an important role in reducing and preventing occupational diseases and reducing the probability of occupational hazards. Generally speaking, occupational hazard identification is to identify the factors that may cause harm to human health in the workplace environment, so as to take preventive measures in advance and reduce the occurrence of occupational diseases! Let's explain the identification methods of several occupational hazard factors!

(1) Monitoring of occupational health hazards in the workplace

This method is the most popular and commonly used method at present, through the analysis and detection of occupational health hazards that may exist or occur in the workplace, including qualitative and quantitative detection.

(2) Literature retrieval methods

Literature retrieval is a method to identify occupational health hazards by consulting the information about occupational health hazards in workplaces, types of work and production processes and their reports on the health of their workers in preventive medicine, hygiene and other journals at home and abroad.

(3) Occupational health survey

This method is suitable for identifying occupational health hazards in traditional industries or traditional process projects, but it may be limited by knowledge or work experience for some new production process projects.

(4) Engineering analysis method

Engineering analysis method is to analyze the general situation of the project, project scale, project composition and main project contents, production technology, production equipment layout, chemical reaction principle, production raw materials and products. For the identified objects, the possible occupational health hazards are speculated. When evaluating new technology and new process construction projects, if analogy objects and analogy data cannot be found, engineering analysis method is generally used to identify occupational health hazards.

(5) Health monitoring

Health monitoring refers to understanding the impact of occupational health hazards on the health of contacts and studying the contact-response (effect) relationship of occupational health hazards through medical examination and occupational health examination file analysis. This result is an important index to judge and verify the identification result of occupational health hazards.

(6) Analogy survey

When using this method, we should pay attention to the similarity between the identified object and the analog object, including the similarity of general engineering characteristics, occupational health protection facilities and environmental characteristics.

(7) Empirical method

Empirical method is an identification method to judge the possible occupational health hazards in the workplace according to the professional knowledge and work experience mastered by professionals. This method is mainly suitable for traditional process industrial projects. Its advantage is simple and easy to operate, but its disadvantage is that it is limited by the appraiser's knowledge, experience and information, and it is easy to appear omissions and deviations in the appraisal process.
