GBZ230-2010 \"Classification of the Hazard Levels of Occupational Exposure to Toxic Substances\" defines them as substances that workers are exposed to during their occupational activities; these substances exist in forms such as raw materials, finished products, semi-finished products, intermediates, reaction by-products, and impurities, and they enter the human body through the respiratory tract, skin, or mouth, thereby posing a threat to the workers’ health.
Basic definition: 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.

Occupational exposure to toxins refers to the situation in which workers come into contact, during production, with 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, thereby posing a threat to health. 2 Classification Principles 2.1 The classification of the degree of hazard associated with occupational exposure to toxins is based on six criteria: acute toxicity, symptoms of acute poisoning, conditions resulting from chronic poisoning, consequences of chronic poisoning, carcinogenicity, and the maximum allowable concentration. 2.2 The grading principle involves a comprehensive analysis based on six grading criteria, with careful consideration given to all of them; the level of hazard is determined according to the classification of the majority of these criteria. However, for certain special toxins, the level can be determined based on their prominent hazards such as acute toxicity, chronic effects, or carcinogenicity. 3 Classification criteria

Occupational exposure to toxins: Substances that workers are exposed to in their professional activities, existing in forms such as 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, thereby posing a threat to the workers’ health. Harm: The health damages and adverse health effects that may occur to workers as a result of occupational exposure to toxins.

These substances can enter the human body through the respiratory tract, skin, or mouth during handling, thereby posing a threat to health. Based on the degree of hazard associated with such toxins, they are classified into four categories: extremely hazardous, highly hazardous, moderately hazardous, and slightly hazardous
