1, chemical factors.
Productive poison. It mainly includes lead: manganese, chromium, mercury, organochlorine pesticides, organophosphorus pesticides, carbon monoxide, carbon dioxide, ammonia sulfide, methane, ammonia and nitrogen oxides. Contact with or working in the environment of these poisons may cause a variety of occupational poisoning, such as mercury poisoning and benzene poisoning.
Productive dust. It mainly includes talcum powder dust, lead dust, wood dust, bone dust and synthetic fiber dust. Working in this dust-producing environment for a long time may cause various pneumoconiosis, such as asbestos lung, coal lung and metal lung.
2. Physical factors.
Abnormal climatic conditions. Mainly refers to the temperature, humidity, airflow and thermal radiation in the production site. Working under high temperature and strong thermal radiation may lead to heatstroke, thermal spasm, heatstroke and so on.
Abnormal air pressure. High pressure and low pressure. Diving under high pressure may cause decompression sickness; Mountain and aviation operations may lead to altitude sickness or aviation sickness.
3. Biological factors. Such as anthrax, forest encephalitis virus and brucellosis on fur.
4. Other factors. The labor organization and system are unreasonable. Excessive labor intensity or improper production quotas. Excessive pressure on individual organs or systems. The building facilities in the production site do not meet the requirements of the design hygiene standards. Lack of appropriate safety technical measures, such as mechanical ventilation and artificial lighting. Lack of dust-proof, anti-virus, heatstroke prevention and cooling, cold-proof and warm-keeping facilities, or imperfect facilities. The safety protection equipment or protector is defective.
