Dangerous goods refer to dangerous substances that may cause harm to human body, objects and environment in the process of production, transportation, storage and use, and may cause explosion, combustion, radioactivity, corrosion and so on. In order to ensure human safety, material safety and environmental safety, countries have formulated strict laws and regulations on the transport of dangerous goods, and adopted a series of norms and measures.

According to the United Nations "Recommendations on the Classification and Labelling of Dangerous Goods", dangerous goods are divided into 9 categories, namely:

1. Explosives and articles;

2. Compressed gases and liquefied gases;

3. Flammable liquids;

4. Flammable solids, self-reactive substances and moisture-reactive substances;

5. Oxidants and organic peroxides;

6. Poisonous and infectious substances;

7. Radioactive substances;

8. Corrosive substances;

9. Other dangerous goods.

For these 9 categories of dangerous goods, different hazard levels and nature requirements are different, and the required packaging, marking, use temperature, and transportation requirements are also different.

in order to ensure the safety of dangerous goods transport, countries have formulated relevant laws and regulations, such as China's "dangerous chemicals safety management regulations", "road truck safety law"; international dangerous goods transport rules are also widely used, such as the United Nations "dangerous goods road transport rules", "dangerous goods maritime rules", "dangerous goods rail transport rules" and so on. These rules impose strict restrictions and requirements on the transport of dangerous goods, stipulate the requirements for packaging, marking, transport vehicles and drivers, and formulate relevant training systems to ensure that all aspects of the transport of dangerous goods can be guaranteed and monitored.

in the process of dangerous goods transportation, but also need to pay special attention to some safety matters, in all aspects must be carefully observed to ensure the safety of dangerous goods transportation. For example, when selecting transportation routes, it is necessary to avoid densely populated areas, concentrated areas of explosive materials, areas susceptible to rainfall, sewage, or floods; standardization, standardization and specialization must be achieved in loading and unloading, packaging, and marking; Attach great importance to the maintenance, inspection and use of transport vehicles to avoid accidents to personnel and the environment.

In short, the safety of dangerous goods transportation is closely related to the safety of the country, enterprises and individuals. Only by attaching great importance to and earnestly complying with relevant regulations can we ensure the safety of dangerous goods transportation and ensure the safety of people's lives and property and social stability.
