But what are poisons in the context of occupational health and safety? In GBZT157-2009 \"Terminology for the Diagnosis of Occupational Diseases\", it is defined as any natural or synthetically produced chemical substance that can have a harmful effect on the body. Generally, chemicals that require only small doses to cause functional or organic damage to the body, or even pose a threat to life, are referred to as poisons. There are neurotoxins, hepatotoxins, nephrotoxins, and hematotoxins. Neurotoxins are chemical poisons that target the nervous system primarily, causing health damage. Hepatotoxins are chemical toxins that cause health damage by targeting the liver as their primary organ. Nephrotoxins are chemical toxins that cause health damage by targeting the kidneys as their primary organ. Hematotoxic agents are chemical toxins that selectively damage the blood and hematopoietic tissues, or target the blood or hematopoietic system as their primary organs.
Toxins are exogenous chemicals that, under certain conditions, can cause damage to living organisms or lead to abnormal reactions in them at relatively low doses. Poisons can be solids, liquids, or gases; upon coming into contact with or entering the body, they can interact with it, triggering physicochemical or biochemical reactions that cause functional or organic damage to the body, and in severe cases, can even be life-threatening.

CO, dust, chlorine, mercury, ammonia, and so on
Whenever I think of chemicals, I imagine them to be toxic
It mainly refers to: dust, radioactive substances, chemical substances, physical factors, biological factors, hazards that cause occupational skin diseases, hazards that cause occupational eye diseases, hazards that cause occupational ear, nose, throat, and oral diseases, hazards that cause occupational tumors, as well as other hazards related to occupational diseases.
Under certain conditions, chemical substances that can disrupt the normal physiological functions of living organisms upon exposure to even small doses, thereby causing certain temporary or permanent lesions, are known as poisons. Various toxic substances generated or used during the production process are collectively referred to as industrial toxins.
Benzene and its harmful substances produced by the coke industry, harmful substances such as hydrogen sulfide and aromatic hydrocarbons generated by the refining industry, as well as harmful substances from the chemical industry.
Occupational exposure to toxins refers to the situation in which workers are exposed, during production, to substances that exist in the form of raw materials, finished products, semi-finished products, intermediates, reaction by-products, and impurities; these substances can enter the human body through the respiratory tract, skin, or mouth during handling, thereby posing a threat to health
