4.1 Classification of dangerous goods
4.1.1 Dangerous goods are divided into 9 categories according to their hazard or most significant hazard. Some categories are further divided into items. The numerical order of categories and items is not the order of danger. 4.1.2 Class 1: Explosives
-1.1: Substances and articles with mass explosion hazard; -1.2: Substances and articles with projection hazard but no mass explosion hazard; -1.3: Substances and articles with combustion hazard and local explosion hazard or local projection hazard or both, but no mass explosion hazard;
-1.4: Substances and articles that do not present a significant hazard; -1.5: Very insensitive substances with mass explosion hazard; -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;
-2.3: Toxic gases.
4.1.4 Class 3: Flammable liquids
4.1.5 Class 4: Flammable solids; substances liable to spontaneous combustion; substances which emit flammable gases in contact with water - 4.1: Flammable solids, self-reactive substances and solid desensitized explosives; 4.2: substances liable to spontaneous combustion;

GB 19359. 1-2003
- Item 6.2: Infectious substances.
4.1.8 Class 7: Radioactive materials
4.1.9 Class 8: Corrosive materials
4.1.10 Class 9: Miscellaneous dangerous substances and articles 4.2 Classification of dangerous goods packaging
4.2.1 The dangerous goods of Class 1, Class 2, Class 7, Item 5.2 of Class 5 and Item 6.2 of Class 6 and other dangerous goods other than self-reactive substances of Class 4 Item 4.1 are divided into three packaging categories according to their degree of danger: Class I packaging - high danger;
Class II packaging - medium danger;
Class III packaging - low danger.
Note: Class I packaging can usually contain dangerous goods of high, medium and low danger, Class II packaging can contain dangerous goods of medium and low danger, and Class III packaging can only contain dangerous goods of low danger. But sometimes it should depend on the characteristics of the specific dangerous goods contained, for example, the relative density of liquid substances should be considered. 4.2.2 In the list of dangerous goods in the United Nations "Recommendations on the Transport of Dangerous Goods Model Regulations" and "International Railway Dangerous Goods Regulations", the packaging categories into which the substances are classified are listed. 5 Requirements
5.1 General technical requirements
5.1.1 Each container must be marked with a permanent mark and logo. 5.1.2 The packaging of dangerous goods for railway transportation should have a reasonable structure, good protective performance, and comply with the specifications of the United Nations "Recommendations on the Transport of Dangerous Goods Model Regulations" and "International Railway Agreement on the Carriage of Dangerous Goods". Its design mode, process and material should be adapted to the characteristics of dangerous goods for railway transportation, facilitate safe loading and unloading and transportation, and withstand the risks under normal transportation conditions. 5.1.3 Dangerous goods should be packed in good quality containers that are strong enough to withstand the impact and loads usually encountered during transportation, including transshipment between transport devices and between transport devices and warehouses, and removal of pallets or outer packaging for subsequent manual or mechanical operations. The construction and closure of the container should prevent any loss of the contents which may occur during transport due to vibration or changes in temperature, humidity or pressure (e.g. caused by altitude) during normal transport conditions. No dangerous residues should adhere to the outside of the container during transport. These requirements apply to new, reused, reconditioned or remanufactured containers. 5.1.4 The parts of the container that are in direct contact with the dangerous goods: a) should not be affected by the dangerous goods or their strength should be significantly weakened by the dangerous goods; b) should not cause dangerous effects in the package, such as causing the dangerous goods to react or react with the dangerous goods. Where necessary, these parts should have an appropriate internal coating or be appropriately treated. 5.1.5 If the container contains liquid, sufficient underfill space should be left to ensure that the container will not leak or be permanently deformed due to expansion of the liquid caused by temperature changes that may occur during transport. Unless specifically required by regulations, liquids shall not fill the container at a temperature of 55°C.
5.1.6 The inner container should be placed in the outer container in such a way that it will not rupture, be punctured or its contents leak into the outer container under normal transport conditions. For those inner packagings that are easy to break or puncture, for example, those made of glass, ceramics, stoneware or certain plastics, they should be fixed in the outer packaging with appropriate cushioning materials. If the contents leak, the protective performance of the cushioning material or the outer packaging should not be significantly impaired.
5.1.7 Dangerous goods should not be placed in the same outer packaging or large packaging if they react dangerously with dangerous goods or other goods and cause the following consequences:
a) Burn or release a large amount of heat;
b) Release flammable, toxic or asphyxiating gases; c) Produce corrosive substances;
d) Produce unstable substances.
GB19359.1—2003
5.1.8 The closure of containers containing moist or diluted substances should ensure that the percentage of liquid (water, solvent or phlegmatizer) will not drop below the specified limit during transportation.
5.1.9Liquids may only be packed into inner packagings that have the appropriate capacity to withstand the internal pressure that may be generated under normal transport conditions. If pressure may be generated in the package due to the release of gas from the contents (due to temperature increase or other reasons), a vent may be installed on the container, but the released gas should not cause danger due to its toxicity, flammability and emission volume. For containers to be transported, the vents should be designed to ensure that liquid leakage and foreign matter penetration are prevented under normal transport conditions. 5.1.10All new, modified and reused containers should be able to pass the tests specified in GB19359.2. Before loading and handing over for transportation, each container should be inspected in accordance with GB19359.3 to ensure that there is no corrosion, contamination or other damage. When a container shows signs of reduced strength compared with the approved design model, it should no longer be used, or it should be refurbished so that it can pass the design type test. 5.1.11Liquids should be packed into containers that have the appropriate capacity to withstand the internal pressure that may be generated under normal transport conditions. The container marked with the hydraulic test pressure specified in 6.2.2d) can only be loaded with liquids with the following vapor pressures: a) at 55℃, the total gauge pressure in the container (i.e. the vapor pressure of the loaded substance plus the partial pressure of air or other inert gas, minus 100kPa) does not exceed two-thirds of the marked test pressure; or b) at 50℃, it is less than four-sevenths of the sum of the marked test pressure plus 100kPa; or c) at 55℃, it is less than two-thirds of the sum of the marked test pressure plus 100kPa. 5.1.12 Each container intended to contain liquids must successfully pass the appropriate airtightness (sealing) test under the following conditions and be able to reach the appropriate test level specified in GB19359.2-2003: a) before being used for transportation for the first time;
b) before any container is used for transportation again after modification or arrangement. When conducting this test, the container does not need to be equipped with its own closure device. If the test results will not be affected, the inner receptacle of a composite container can be tested without an outer container. The following may be exempted from testing: - Inner receptacles of composite packaging (glass, ceramic or stoneware); Lightweight standard metal packaging.
5.1.13 Containers used for solids that will become liquid at temperatures that may be encountered during transportation should also be capable of containing the substance. 5.1.14 Containers used for powdered or granular substances should be sieve-proof or equipped with liners. 5.1.15 Inner packagings should be fixed and cushioned to limit their movement in the outer packaging. To prevent rupture and leakage under normal transportation conditions, when the inner packaging is glass or ceramic packaging, and Class I or Class II outer packaging is used to contain liquids of Class 3, Class 4, Class 8 and Class 5 Item 5.1, Class 6 Item 6.1, there should be absorbent cushioning material outside the inner packaging. The absorbent cushioning material should not react dangerously with the dangerous substances contained in the inner packaging, and the leakage of the contents should not cause dangerous chemical reactions or change the protective properties of the cushioning material. 5.1.16 The performance and thickness of the outer packaging material should ensure that the chemical stability of the contents will not be changed due to frictional heat generated during transportation. 5.1.17 When dangerous goods are contained in combination containers, the closure of the inner container cannot be inverted. The outer packaging should be clearly marked with a mark indicating the direction of operation.
5.1.18 Damaged, defective, leaking or non-compliant dangerous goods packages, or overflowing or leaking dangerous goods, can be transported in salvage containers.
5.1.19 Appropriate measures should be taken to prevent damaged or leaking packages from moving excessively in the salvage container. When the salvage container contains liquid, sufficient inert absorbent material should be added to eliminate the presence of free liquid. 5.2 Special packaging requirements for Class 1 explosives 5.2.1 The provisions of 5.1 should be met.
5.2.2 All containers for Class 1 goods shall be designed and manufactured to meet the following requirements: a) They shall be able to protect explosives so that they will not leak out or increase the risk of unintentional ignition or initiation under normal transport conditions, including when there are foreseeable changes in temperature, temperature and pressure; b) Complete packages can be safely moved under normal transport conditions; 5
GB19359.12003
c) Packages shall be able to withstand any load imposed on them by foreseeable stacking during transport, without increasing the danger of explosives, the protective function of the container will not be impaired, and the way or degree of deformation of the container will not reduce its strength or cause instability in the stack.
5.2.3 All explosive substances and articles for transport shall be classified in accordance with the procedures specified in the United Nations "Recommendations on the Transport of Dangerous Goods Model Regulations" and "International Railway Dangerous Goods Regulations". 5.2.4 Class 1 goods shall be packaged in accordance with the provisions of the United Nations "International Railway Dangerous Goods Regulations". 5.2.5 Containers shall comply with the Class II packaging test requirements in GB19359.2-2003, and shall comply with the provisions of 5.1.13 and 6.1.4. Metal containers shall not be used for Class I packaging.
5.2.6 The closure device of the container containing liquid explosives shall have a double protection device to prevent leakage. 5.2.7 The closure device of the metal drum shall include a suitable gasket; if the closure device includes a thread, the explosive substance shall be prevented from entering the thread. 5.2.8 The container of water-soluble substances shall be waterproof. Containers for transporting desensitized or desensitized substances must be closed to prevent changes in concentration during transportation.
5.2.9 When the packaging comprises a double envelope with an intermediate water filling and the water may freeze during transport, sufficient antifreeze should be added to the water to prevent freezing. Antifreeze agents which may cause combustion due to their inherent flammability should not be used. 5.2.10 Nails, clasps and other closures made of metal without a protective coating should not be inserted into the interior of the outer packaging unless the inner packaging is capable of preventing the explosive from coming into contact with the metal.
5.2.11 Inner packagings, fittings and cushioning materials and the placement of explosive substances or articles in the packages should be such that the explosive substances or articles will not disperse in the outer packaging under normal conditions of transport. Metal parts of articles should be prevented from coming into contact with metal packagings. Articles containing explosive substances not enclosed in outer shells should be separated from each other to prevent friction and impact. This purpose can be achieved by using cushions, pallets, partitions in inner or outer packagings, molded liners or receptacles. 5.2.12 The material of the packaging should be compatible with the explosives contained in the package and impermeable to the explosives to prevent interaction or leakage between the explosives and the packaging materials that would make the explosives unsafe for transport or cause a change in the hazard division or compatibility group. 5.2.13 Explosive substances should be prevented from entering the recesses of seamed metal containers. 5.2.14 Plastic containers should not easily generate or accumulate sufficient static electricity that, when discharged, could cause the explosive substances or articles in the package to be triggered, ignited or started.
5.2.15 Large, solid explosive articles normally used for military purposes may be transported unpackaged if they are without a means of initiation or with a means of initiation that contains at least two effective protective devices. When such articles are propelled or self-propelled, their initiation system should be protected from stimuli encountered under normal conditions of transport. Such unpackaged articles may be fixed to a frame or packed in a crate or other suitable handling or storage device so that they will not move loose under normal conditions of transport. 5.2.16 Explosive substances should not be packed in inner or outer packagings where the internal and external pressure differences caused by thermal or other effects may cause explosion or rupture of the package.
5.2.17 If loose explosive substances or explosive substances without shells or partially exposed explosive substances may come into contact with the inner surface of metal packagings (1A2, 1B2, 4A, 4B and metal receptacles), the metal packagings should have inner linings or coatings. 5.2.18 Inner packagings, accessories, cushioning materials and explosive substances should be firmly placed in the packaging to ensure that they will not cause dangerous movement during transportation.
5.2.19 Electric detonators should prevent electric and magnetic radiation and stray current. Explosives equipped with ignition or initiation devices must be effectively protected to prevent accidents under normal transportation conditions. 5.3 Special packaging requirements for organic peroxides (Class 5, Division 5.2) and self-reactive substances (Class 4, Division 4.1) 5.3.1 For organic peroxides, all receptacles should be "effectively closed". If the package may generate a large internal pressure due to the release of gas, it may be equipped with a vent, but the discharged gas should not cause danger, otherwise the filling degree should be limited. The structure of any venting device should prevent the liquid from leaking when the package is upright, and should prevent impurities from entering. If there is an outer container, it should be designed so that it will not interfere with the function of the venting device.
5.3.2 The packaging of organic peroxides with explosion hazards should also comply with other relevant requirements of the "Regulations for the International Transport of Dangerous Goods by Rail".
GB19359.1—2003
5.3.3 The packaging of organic peroxides should ensure that it does not chemically react with all materials in contact with the contents, has no effect on the characteristics of the contents, and when leakage occurs, the cushioning material is not easy to burn and will not cause the decomposition of the organic peroxide. 5.4 Special requirements for various packages shall comply with Appendix A. 6 Coding and marking

The barrel of a metal barrel with a capacity greater than 60L shall usually be equipped with at least two expansion roll hoops or two separate roll hoops. If separate roll hoops are installed, they shall be installed firmly and shall not move. The roll hoops shall not be spot welded.
The diameter of the openings on the barrel or cover of a non-removable cover (1N1) metal barrel for filling, emptying and ventilation shall not exceed 7cm. Metal barrels with larger openings shall be regarded as removable cover (1N2) metal barrels. The openings on the barrel and cover Closures shall be designed and installed so that they remain tight and leak-proof under normal conditions of transport. Closure flanges shall be welded to make the seams leak-proof. Gaskets or other seals shall be used unless the closure itself is leak-proof.
The closures of removable-top metal drums shall be designed and installed so that they remain tight and leak-proof under normal conditions of transport5
. Gaskets or other seals shall be used for all removable caps. The body and lid shall be made of steel plate, at least 99% (mass fraction) pure aluminum or aluminum alloy. Appropriate type and sufficient thickness of material shall be used according to the capacity and purpose of the tank. 2 The flanges of steel shall be mechanically joined or welded. The seams of the body of steel tanks for liquids containing more than 40L shall be welded. The seams of the body of steel tanks for liquids containing less than or equal to 40L shall be mechanically joined or welded. For aluminum tanks, all seams shall be welded. If the flange has seams,An additional reinforcing ring should be added. 3 The opening diameter of the can (3AI and 3B1) should not exceed 7 cm. Cans with larger openings will be considered as removable head models (3A2 and 3B2). Closures should be designed to remain tight and leakproof under normal transport conditions. Unless the closure itself is leakproof, a gasket or other seal should be used.
4 If the materials used for the can body, cover, closure and connectors are incompatible with the substances transported, an appropriate internal protective coating or treatment should be applied. Under normal transport conditions, these coatings or treatments should always maintain their protective properties. The wood used should be thoroughly air-dried to the commercially required dryness and have no defects that would impair the performance of the barrel. If a material other than plywood is used to make the barrel cover, its quality should be equal to that of the plywood.
2 The barrel body should be made of at least two layers of plywood, and the barrel cover should be made of at least three layers of plywood. The layers of plywood should be firmly bonded together with a water-resistant adhesive according to the cross grain. 3 The barrel body, barrel cover and their joints should be designed according to the capacity and purpose of the barrel. 4 To prevent leakage of the contained materials, kraft paper or other materials with equivalent performance should be used as the barrel cover lining. The lining should be tightly fastened to the barrel cover and extend around the entire barrel cover. 450
