How much columns does The Hazardous Materials Table contain?

Each type of item that the US Department of Transportation has identified as a hazardous material for transportation reasons is included in the Hazardous Materials Table (almost 3,000 so far). This table might serve as a reference for shippers and carriers. The Hazardous Materials Table comprises eight columns that list the material's name, danger class, identification number, and other information along with the route of transportation (air, ground, water, etc.). Consult the official CDL manual in your state for more details.
