Dangerous goods are generally industrial raw materials or products. Due to their special physical and chemical properties, corresponding rules must be observed during contact and handling to avoid accidents and disasters. The transportation link is a highly technical and professional. The main features of the work are:

1. There are many categories and different properties

According to the danger of dangerous goods, the "Classification and Numbering of Dangerous Goods" (GB6944-2005) divides dangerous goods into 9 categories and 22 items. Each item also contains specific dangerous goods. There are 2,763 product names registered in the "List of Dangerous Goods" (GB12268-2005). The physical and chemical properties of 2763 kinds of dangerous goods and the new ones that are added every year are very different.

2. Dangerous

Dangerous goods, as a special category, are very dangerous in road transportation and are likely to cause casualties and property losses. Dangerous goods transportation accidents caused great harm. For example, the liquid chlorine leakage accident on the Beijing-Shanghai Expressway occurred on March 29, 2005. The driver and the escort fled after reporting the case, delaying the time of emergency evacuation, resulting in 28 deaths. More than 20,000 mu of land was polluted, and the direct economic loss was 29.01 million yuan. Among the 9 categories of dangerous goods, each category has its own unique hazard and has strict requirements on external conditions.

3. There are many relevant rules and regulations in transportation management

The transportation of dangerous goods is an important part of the entire road cargo transportation. In addition to complying with the common regulations for road cargo transportation, such as the "People¡¯s Republic of China Road Traffic Management Regulations" and the "Highway Traffic Management Measures", many special Provisions include:

(1) Relevant United Nations regulations

"Recommendations on the Transport of Dangerous Goods" and "International Agreement on the Transport of Dangerous Goods by Road", etc.

(2) National standards for road transportation of dangerous goods

"Classification and Numbering of Dangerous Goods" (GB6944-2005), "List of Dangerous Goods" (GB12268-2005), "Dangerous Goods Packaging Marks" (GB190-90), "General Technical Requirements for Dangerous Goods Transportation Security" (GB12463-90) ), "Road Transportation of Dangerous Goods Vehicle Signs" (GB13392-2005), "General Technical Requirements for Atmospheric Pressure Vessels (Tanks) for the Transportation of Liquid Dangerous Goods by Motor Vehicles" (GB18564-2001), "Classification and Marking of Commonly Used Dangerous Chemicals" ( GB13690-92), "Picture Signs for Packaging, Storage and Transportation" (GB191-2000), "Regulations for the Safe Transportation of Radioactive Materials" (GB11806-2004), etc.

(3) Industry Standards for Road Transport of Dangerous Goods
