According to the arrangement of the State Administration of Petroleum and Chemical Industry, the National Chemical Equipment Design Technology Center organized the compilation and revision of the design standards and technical regulations for chemical equipment design. As a directive industry standard guiding the design and manufacture of chemical equipment, this standard classifies hundreds of common chemical media according to their degree of toxicity and explosion hazard based on the classification and technical requirements of pressure vessels, and determines the corresponding classification principles and basis. This standard is edited by Huatai Engineering Company (formerly the Second Design Institute of the Ministry of Chemical Industry and Shanghai Chemical Toxicity Testing Institute.

Scope of Application
In order to determine the categories and technical requirements of pressure vessels, this standard classifies the toxic hazards and explosion hazard levels of the media.
This standard has classified the toxic hazards and explosion hazard levels of chemical media (including raw materials, finished products, intermediates, reactants, reaction by-products and impurities, etc.) used or stored in chemical pressure vessels, and determined the categories and technical requirements for compactness and sealing of pressure vessels accordingly. 2. Reference Standards
GB5044-85 (Classification of Hazard Levels of Occupational Exposure to Toxic Substances, State Administration of Quality Supervision, Inspection and Quarantine, Regulations on Safety Technical Supervision of Pressure Vessels (1999) (hereinafter referred to as "Regulations") 3
Classification Principles
3.0.1 The toxicity hazard and explosion hazard of chemical media determined in this standard refer to the severity of the pressure vessel causing the medium to come into contact with the human body due to an accident during the production process, resulting in explosion, or the severity of occupational chronic hazards caused by frequent leakage. 3.0.2 The degree of toxicity hazard of chemical media is classified based on the six classification indicators specified in GB5044 (see Appendix A "Basis for Classification of Toxicity Hazard Degree" for details). According to the degree of toxicity hazard, it is divided into extremely hazardous, highly hazardous and moderately hazardous categories. (6) 3.0.3 When used to determine the category of pressure vessels, the degree of toxicity hazard should be classified according to the accident status and the hazards caused by the contact between the medium and the human body. For this reason, this standard is based on the two indicators of acute toxicity and maximum allowable concentration, and considers the attributes of other indicators, and conducts comprehensive analysis and comprehensive weighing for classification. Table 3.0.3-1 to Table 3.0.3-3 lists chemical media with common toxicity levels of extreme hazard, high hazard and moderate hazard. 3.0.4: When determining the technical requirements for the tightness and sealing of chemical pressure vessels, in addition to the accident status, the chronic potential hazards caused by frequent leaks should also be taken into account. For this reason, the three indicators of acute toxicity, maximum allowable concentration and carcinogenicity are mainly considered, and the classification is carried out after comprehensive analysis and comprehensive weighing considering the attribution of other indicators. For some media, they are classified according to their prominent hazard level (such as carcinogenicity). Therefore, the category attribution of a few media listed in Table 3.0.3-1 to Table 3.0.3-3 has been adjusted. See the notes in the table for details. 3.0.5
Based on the provisions of the "Regulations on Safety Technical Supervision of Pressure Vessels", the categories of explosive hazardous media are defined (Note 2). Explosive hazardous media refer to gases or liquids whose vapors, thin films and air form explosive mixtures, and whose lower explosion limit is less than 10%, or the difference between the upper and lower explosion limits is greater than or equal to 20%. See Table 3.0.5 for details. 3.0.6 When multiple chemical media are involved in use, the media with the highest toxicity or explosion hazard among the components of the media should be considered: When the content of a hazardous substance in the medium is extremely small, it should be comprehensively considered according to its degree of hazard and its meaning. According to the classification principles of this standard, the process design of the design unit or the production technology department of the user unit shall determine the category. 3.0: For chemical media not included in this standard, the above classification principles shall be avoided and classified with reference to the classification categories of similar media:
Table 3.0. 3-1
Acetoacetaldehyde (Diboron)
Ethylenimine (Ethyleneamine)
Dimethylnitrosamine

Note: When the classification of group toxicity is used to determine the technical requirements for the tightness and sealing of pressure vessels, chloroethylene and ethylene glycol should be included in this standard as extremely hazardous chemical media.
Note 1: Chemical media with a toxicity level of "mildly hazardous" should not be included in this standard. Note 2: The "explosive hazardous media" referred to in this standard are also the "flammable media" referred to in the "Regulations on Safety Technical Supervision of Pressure Vessels". 3
