Table of all UN Number Chemical Codes[edit]

  • If it is at all possible, I suggest we attempt to make a complete table of all these chemical codes and their real chemical names for reference. I know we link to a document that has them, but having a table on Wikipedia itself might be useful for people that can not view the pdf format, and for archival purposes. -JR 15:21, 9 November 2006 (UTC)

  • The two are separate subjects so should stay as separate topics. A number of substances will overlap the two though so linking between the two topics would be beneficial

NA numbers are not the same as DOT numbers[edit]

An NA number is NOT a DOT Number as explained in the article. A DOT number identifies a carrier, driver or vehicle. An NA number identifies a substance. NA numbers, identified in 49 CFR 172.101, are in the range of NA0000 through NA3999, and NA9000 through NA9999. Please correct the article.

"Hazardous Substances" used in wrong manner[edit]

The use of the phrase "hazardous substances" is misleading. These UN numbers are the identifiers of "Hazardous Materials" in the US or "Dangerous Goods" in the rest of the world (don't get me started.) "Hazardous Substances" are materials, that are packaged above their "reportable quantitites" and are known and listed by US EPA as materials that pose environmental dangers for transportation purposes--they are then regulated as "hazardous materials."

They are not dangerous goods "in the rest of the world".

Scope of article[edit]

I think we need to change this article a little along with all the lists associated with it. This is the base article for the UN and NA numbering schemes. The two are essentially the same thing, all UN numbers are NA numbers. The NA adds some additional numbers and changes descriptions on others. The lists should be updated to include all the NA numbers and descriptions. This would simplify the whole subject area. List of NA numbers and NA/UN exceptions would not be needed as they would be incorporated into the Lists of UN numbers at appropriate locations with an additional list for the NA numbers above 3600. -- GB fan 22:46, 21 November 2016 (UTC)
