Explosive Solid or liquid substances that can undergo violent chemical reactions under external influences (such as heat, pressure, impact, etc.), instantly produce a large amount of gas and heat, cause the surrounding pressure to rise rapidly and explode, and cause damage to the surrounding environment. It also includes items that have no overall explosion hazard but have combustion, projection and smaller explosion hazards. 3.2 Gas Substances with a vapor pressure greater than 300kPa at 50℃.

Miscellaneous dangerous substances and articles: miscellaneons are substances and articles that may cause dangers during transport that are not included in other categories. This category includes, among other things, liquid substances submitted for transport at a temperature greater than or equal to 100°C or solid substances submitted for transport at a filtration rate greater than or equal to 240°C. 4 Classification 4.1 Classification of dangerous goods 4.1.1 Dangerous goods are divided into 9 categories according to their specific hazard or most important hazard. Some categories are further divided into items. The reverse order of the category and item numbers is not the order of hazard level. 4.1.2 Class 1: Explosives -1, Item 1: Substances and articles with a mass explosion hazard -1, Item 1: Substances and articles with a projection hazard but no mass explosion hazard; -1, Item 1: Substances and articles with a combustion hazard and a local explosion hazard or a local projection hazard or both of these hazards, but no mass explosion hazard; -1, Item 1: 4: Substances and articles that do not present a significant hazard -1, Item 1: 5: Very insensitive substances with a mass explosion hazard; -1, Item 1: 6: Extremely insensitive articles with no mass explosion hazard. 4.1.3 Class 2: Gases -2.1: Flammable gases; -2.2: Non-flammable and non-toxic gases; -23: Toxic gases. 4.1.4 Class 3: Flammable liquids 4.1.5 Class 4: Flammable solids; substances that are prone to spontaneous combustion: substances that emit flammable gases when in contact with water - 4.1: Flammable solids, self-igniting substances and decomposing explosives #4.2: Substances that are prone to spontaneous combustion! 4.3: Substances that emit flammable gases when in contact with water. 4.1.6 Class 5: Oxidizing substances and organic peroxides - 5.1: Oxidizing substances: - 5.2: Organic peroxides. 4.1.7 Class 6: Toxic and infectious substances - 6.【Item: Toxic substances; -- 6.2 Item: Infectious substances. 4.1.8 Class 7: Radioactive substances 4.1.9 Class 8: Corrosive substances 4.1.10 Class 9: Miscellaneous dangerous substances and articles 4.2 Classification of dangerous goods packaging CB19458-2004 Except for dangerous goods of Class 1, Class 2, Class 7, Items 5.2 and 6.2, the packaging of other types of dangerous goods can be divided into three packaging levels according to the degree of danger, namely, I level packaging -- · Highly dangerous substances: Packing level II - Medium dangerous substances: Packing level III - Mildly dangerous substances. The classification of the degree of danger of various emergency goods can be determined by tests with dangerous characteristics. 5 Requirements 5.1 Safety requirements 5.1.1 The manufacturer of a new product or the party entrusting the application for the classification of the product shall provide all available safety data about the product, such as toxicity data. 5.1.2 When explosiveness is suspected, a small-scale preliminary test should be carried out first, and then a larger amount of material should be tested. Preliminary tests include determining the sensitivity of the substance to mechanical stimulation (impact and friction) as well as to heat and flame. 5.1.3 In tests involving the initiation of potentially explosive substances or articles, a safe waiting time should be maintained after initiation. 5.1.4 Special care should be taken when handling tested samples, and tested samples should be destroyed as soon as possible after testing. 5.2 Test requirements 5.2.1 Tests on hazardous properties should be carried out according to the test conditions. If no tolerance is given in the test, this means that the accuracy is determined by the decimal place of any given dimension, for example 1.1 means 1.05 to 1.15. If the conditions during the test deviate from the given conditions, the reason for the deviation should be stated in the test report. 5.2.2 The composition of the test sample should be consistent with the concentration of the substance intended for transport. The content of each active substance and each diluent should be listed in the test report with an accuracy of at least 2% (mass fraction). Ingredients that may have a significant effect on the test results should be clearly stated in the test report. 5.2.3 All test materials in contact with the test substance should not affect the test results. If the effect cannot be excluded, precautions should be taken to prevent the effect on the test results. The precautions taken should be stated in the test report. 5.2.4 The test should be carried out under conditions (temperature, density) that represent the transportation conditions. If the listed test conditions do not include transportation conditions, additional tests of the intended transportation conditions are required. 5.2.5 If the test results are related to the particle size of the substance, the relevant physical conditions should be stated in the test report. 6 Tests 6.1 The 9 major categories of dangerous goods classification tests specified in the United Nations "Recommendations on the Transport of Dangerous Goods Model Regulations (13th revised edition)" are tested item by item, unless there is a clear basis for exempting some items. 6.2 When a substance, mixture or solution has more than one hazard and its name is not listed in the Dangerous Goods List in Chapter 3.2 of the United Nations "Draft Model Regulations for the Transport of Dangerous Goods (13th revised edition), the category is determined in the following order: a) Class 1 substances and articles: GB 19458-2004 b) Class 2 gas; c) Class 3 desensitized explosives; d) 4.1 self-reactive substances and desensitized explosives: e) 4.2 pyrophoric substances; f) 5.2 substances: g) 6.1 substances with Class 1 packaging absorption; h) 6.2 substances; i) Class 7 substances, except for radioactive substances in excepted packages, radioactive substances with other dangerous properties should be classified into Class 7, and subsidiary risks should also be determined. 6.3 For goods with multiple hazards and no specific names in the Dangerous Goods List in Chapter 3.2 of the United Nations Recommendations on the Transport of Dangerous Goods Model Regulations (13th Edition), it means that the general strict packaging category of the goods related to the hazard takes precedence over other packaging categories, see Appendix A. 7 Mark 7. 1 Types of signs There are 9 categories and 21 types of signs for the hazardous characteristics of dangerous goods, which are listed in Appendix B. 7.2 Shape of the sign The shape of the sign is a square (diamond) with a 45° angle, and the general minimum size is 100mm×100mm. It consists of four parts: pattern, text description, background color, hazard class number. 7.3 Use of signs 7. 3. 1 Principles of use of signs When a dangerous good has more than one hazard, in addition to using signs to indicate the main hazard class, corresponding signs should also be used to indicate other important hazard classes. 7.3.2 Methods of use of signs Follow the relevant provisions of GR190. 8 Inspection rules 8.1 Inspection: According to Chapter 5 and Section 6 of this standard 8.2 Under the following circumstances, the manufacturer shall request the relevant inspection department to conduct the inspection of hazardous characteristics when submitting the new product for transportation: When one of the following circumstances occurs, the factory shall conduct the inspection of hazardous characteristics: When a new product is not produced or the old product is changed: After formal production, if there are major changes in materials and processes, which may affect product performance: Once every six months during normal production: When the product is resumed after a long period of suspension of production, when the factory inspection results are significantly different from the previous performance inspection results: When the national quality supervision and inspection agency It is proposed to conduct performance test. 8.3 Each type of hazardous characteristic should be tested and determined according to an effective test method. 8.4 When multiple tests are required to determine the hazardous characteristics, an effective test procedure should be established. 8.5 When the hazardous characteristic report is obtained, the dangerous goods with known hazards shall not be transported, sold or used.
