Occupational hazard factors include:
1, chemical factors: toxic substances, such as lead, mercury, butadiene, styrene, high aromatic oil and productive dust, such as petroleum coke dust, metal dust and cement dust.
2. Physical factors: abnormal meteorological conditions, abnormal air pressure, noise, vibration, non-ionizing radiation, ionizing radiation, etc.
3. Biological factors, such as Bacillus anthracis and mold on bagasse.
4. Time factors, such as long working hours at night and unreasonable rest system. In actual production, occupational hazards often do not exist alone, and the joint existence of multiple occupational hazards will often aggravate the impact on workers' health.
Occupational hazards refer to various hazards that may lead to occupational diseases for workers engaged in occupational activities. Occupational hazard factors include: various harmful chemical, physical and biological factors existing in occupational activities and other occupational hazards generated in the process of operation.
Occupational taboo refers to a special personal physiological or pathological state in which workers are more vulnerable to occupational hazards and occupational diseases than the general occupational population when they are engaged in specific occupations or exposed to specific occupational hazard factors, or may aggravate their own diseases or induce diseases that may pose a danger to the lives and health of others in the process of engaging in operations.
Occupational hazards and factors harmful to human body in work.
Not all the factors harmful to human body in work are occupational hazards, only those listed in the Catalogue of Occupational Hazards are occupational hazards. If it is included, the enterprise should declare the occupational hazard factors and entrust a third-party agency to carry out testing every year, and the control should not exceed the standards allowed by the state. The occupational health supervision department will check this and face a fine if it violates the law.
Harmful factors that are not included do not involve occupational diseases and are managed by enterprises themselves. Of course, those involving dangerous goods will be supervised by other regulatory authorities.
Dust is often a mixture, some can cause pulmonary fibrosis and lead to pneumoconiosis, some contain toxic and harmful substances that can cause poisoning, some can cause allergies, some can cause cancer, some have biological hazards such as brucellosis and anthrax, and some can be flammable or promote combustion to cause fire or explosion, so dust is often listed separately.
Radiation is very harmful to human body, which will cause damage to local and whole body. As we all know, nuclear radiation has caused great casualties to local people.
