Minor questions regarding the classification of major hazard sources for hazardous chemicals
Thread Content
This post was last edited by three three three_KAspz on 2023-8-2 at 13:58. I found this description confusing today; how do you all understand the categories of hazardous chemicals listed in Table 2? For example, how are oxidizing solids and liquids of Category 1 and Category 2 distinguished?
In accordance with the series of standards on the Classification and Labelling of Chemicals (GB 30000.2–GB 30000.29), chemicals are divided into 28 categories and 95 hazard classes, in line with the United Nations’ Globally Harmonized System of Classification and Labelling of Chemicals (GHS). For example, “oxidizing solids” are classified into categories 1, 2, and 3 in accordance with standard GB 30000.15 \"Classification and Labelling of Chemicals – Part 15: Oxidizing solids\".
The classification categories for major hazardous sources of hazardous chemicals are used to categorize such chemicals based on their hazard nature and degree of risk. The categories in Table 2 are generally arranged from highest to lowest risk, with Category 1 representing the highest risk level and Category 2 representing a higher risk level. Oxidizing solids and liquids are hazardous chemicals that can cause combustion or accelerate combustion when in contact with air or other substances. In the identification of major hazard sources for hazardous chemicals, oxidizing solids and liquids are classified into Category 1 and Category 2, with the distinction possibly based on their specific physical and chemical properties as well as the degree of impact they have on the environment and humans. Specifically, if a chemical has a high oxidizing capacity, that is, it tends to cause combustion more easily when in contact with air or other substances, and may pose more severe hazards to the environment and humans, then it may be classified as Category 1 oxidizing solids or liquids. If a chemical has low oxidizing power, meaning it is less likely to cause combustion upon contact with air or other substances, and poses a lower level of hazard to the environment and humans, then it may be classified as an oxidizing solid or liquid of Category 2. In summary, the distinction between the categories of oxidizing solids and liquids mainly depends on their specific hazardous properties and the potential degree of harm they pose to the environment and human health. .
Thank you very much:handshake:handshake
You’re welcome. If you have any other questions, feel free to ask at any time! Wish you all the best! :blush::handshake: .
It is specified in the Implementation Guidelines for the Catalog of Hazardous Chemicals (2015 edition)
For specific classification criteria, refer to GB30000 \"Specifications for the Classification and Labelling of Chemicals\". For common hazardous chemicals, consult the Guidelines for the Implementation of the Catalogue of Hazardous Chemicals, which already provides a classification system
I felt that some parts were hard to confirm after reading it, so I found a catalog later on:lol:lol
