UN number is a number with four digits on dangerous goods. Since the rules for handling hazardous materials were different in each country, the UN's specialized organization lists hazardous materials and numbers them so that they can be operated uniformly.
U.N. numbers are usually written with a UN on the head, such as UN0004, followed by a four-digit number. There is no clear regularity in this number, but if you can identify the number, you will be able to understand what kind of dangerous goods they are, how to handle them, how to load them, and how to isolate them.
Although the numbers are not regular, for example, among dangerous substances, gunpowder has been numbered from the 1st to the 500th series, such as UN0004 to UN0509. On the other hand, from UN1001 to UN3500 series, the categories of hazardous materials are mixed up, and it is impossible to say what kind of hazardous materials they are.
The meaning of the UN number is basically a unique number for identifying and identifying dangerous goods and dangerous goods. Although the numbers themselves are meaningless, they can be used to determine dangerous goods, so they are also listed on MSDS of products intended for export.
Once the UN number is established, there will be exceptions as well as transportation methods, containers that can be used, packaging methods, hazards, handling methods, loading methods, isolation methods, etc.
