1. Chemicals
Refers to chemical elements, compounds and mixtures, both natural and synthetic.
2. Hazardous Chemicals
All chemicals with explosive, flammable, poisonous, and corrosive properties that are likely to cause personal injury and property damage during production, storage, operation, use, transportation, and disposal require very strict safety measures and special protective chemicals.
3. The Dangerous Goods Name List (GB 12268-2005) divides dangerous goods into nine major categories
The first category: explosives;
The second category: gas;
The third category: flammable liquids;
The fourth category: flammable solids, substances that are easy to spontaneously combust, and substances that emit flammable gases in contact with water;
The fifth category: oxidizing substances and organic peroxides;
The sixth category: toxic substances and infectious substances;
The seventh category: radioactive materials;
Class 8: Corrosive substances;
Ninth category: Miscellaneous dangerous substances and articles.
4. Method for determining hazardous chemicals
According to the characteristics of the chemical itself such as flammability, toxicity, corrosivity, explosiveness, oxidation, reactivity, etc., according to the "Dangerous Goods Name List" (GB12268-2005), "Very Toxic Chemicals Catalog" and "Dangerous Chemical Name List 》 Determine whether the chemical is a hazardous chemical, and determine the hazardous category.
5. Chemical safety technical specifications and chemical safety labels (one book, one sign)
Article 14 of the "Regulations on the Safe Production of Dangerous Chemicals" clearly stipulates that: enterprises that produce hazardous chemicals should attach a chemical safety technical manual that is completely consistent with hazardous chemicals in the packaging of hazardous chemicals, and include The outer package) is affixed or tied with a chemical safety label that is exactly the same as the hazardous chemical in the package.
When a hazardous chemical production enterprise discovers that the hazardous chemicals it produces have new hazardous characteristics, it shall immediately make an announcement and promptly revise the safety technical specifications and safety labels.
Based on the above regulations, hazardous chemical production and operation units must understand the safety technical specifications and safety labels of hazardous chemicals.
(1) Safety label: refers to the combination of words, graphic symbols and codes to indicate the hazards and safety precautions of chemicals. Specific labels affixed, tied or sprayed on chemical packaging.
For example, Guangzhou Petrochemical's methanol safety label is as follows:
(2) Safety Technical Manual (abbreviated as MSDS): It is a comprehensive document on chemical explosion, toxicity and environmental hazards, safe use, emergency disposal of leakage, main physical and chemical parameters, laws and regulations, etc. Including chemical and company identification, composition / composition information, hazard overview, first aid measures, firefighting measures, leakage emergency treatment, handling and storage, exposure control / personal protection, physical and chemical properties, stability and reactivity, toxicological data, There are 16 parts of ecological information, waste disposal, transportation information, regulatory information, and other information.
PVC Resin is easy to process, and can be processed by molding, lamination, injection molding, extrusion, calendering, blow molding and other hollow methods. Polyvinyl chloride is mainly used to produce artificial leather, film, wire sheath and other plastic soft products, but also can produce plates, doors and windows, pipes and valves and other plastic hard products.
