Biological occupational hazards include

Biological factors are an important part of occupational hazards. Pathogenic microorganisms, parasites, animals and plants, insects, etc. Substances existing in raw materials and production environment that are harmful to the health of occupational population and their bioactive substances are collectively referred to as biological hazards. Such as Bacillus anthracis and Brucella attached to animal fur, irritating, toxic or allergic bioactive substances produced by some animals and plants, schistosomiasis cercariae of livestock and poultry, etc. Occupational harmful biological factors mainly refer to pathogenic microorganisms and pathogenic parasites, such as Brucella, anthrax and forest encephalitis virus. According to occupational exposure limits-Chemical Harmful Factors in Workplace (GBZ 2. 1-2007), the allowable concentrations of Beauveria bassiana spores and subtilisin in workplace air are shown in Table 1.

Hazardous factor operation

Common biological harmful factors mainly exist in the experimental research of pathogenic microorganisms, medical and health technical services, biotechnology industry, animal breeding and slaughtering, plant planting and other related industries.

(1) pathogenic microorganism laboratory

Laboratory staff engaged in research, teaching, detection, diagnosis and other activities related to pathogenic microorganisms (viruses) may cause corresponding health damage due to contact with highly pathogenic microorganisms.

(2) Medical and health industry

Workers engaged in medical and health technical services may cause corresponding health damage due to contact with pathogenic microorganisms.

(3) Biological high-tech industry

The object of modern biotechnology represented by DNA recombination technology is mainly living organisms. Workers often come into contact with pathogenic microorganisms or non-pathogenic microorganisms or their toxic and harmful metabolites in the process of production and operation, which may cause harm to their health.

(4) Animal related industries

Workers engaged in animal-related industries such as animal husbandry, animal feeding and animal slaughter are at risk of being infected with animal-borne infectious diseases.

(5) Industries related to plants

Agricultural production personnel may cause farmers' lungs due to exposure to organic dust; Mushroom cultivation and picking workers can induce mushroom lung by inhaling a large number of fungal spores; People who work in rice fields will have various skin diseases; You may come into contact with the forest encephalitis virus in the operation activities in the forest area.

Legal basis:

Law of People's Republic of China (PRC) on the Prevention and Control of Occupational Diseases

Article 2 This Law is applicable to occupational disease prevention and control activities in People's Republic of China (PRC).

Occupational diseases mentioned in this Law refer to diseases caused by workers of enterprises, institutions and individual economic organizations who are exposed to dust, radioactive substances and other toxic and harmful factors in their professional activities.

The classification and catalogue of occupational diseases shall be formulated, adjusted and published by the administrative department of health of the State Council in conjunction with the administrative department of labor security of the State Council.
