9.3.3 – Lists of Regulated Products

Placards. Placards are used to warn others of hazardous materials. Placards are signs put on the outside of a vehicle and on bulk packages, which identify the hazard class of the cargo.

A placarded vehicle must have at least four identical placards. They are put on the front, rear, and both sides of the vehicle. Placards must be readable from all four directions. They are at least 10 3/4- inches square, square-on-point, in a diamond shape.

Cargo tanks and other bulk packaging display the identification number of their contents on placards or orange panels or white square-on-point displays that are the same size as placards.

Identification numbers are a four-digit code used by first responders to identify hazardous materials. An identification number may be used to identify more than one chemical. The letters “NA” or “UN” will precede the identification number. The United States Department of Transportation’s Emergency Response Guidebook (ERG) lists the chemicals and the identification numbers assigned to them.

There are three main lists used by shippers, carriers, and drivers when trying to identify hazardous materials. Before transporting a material, look for its name on three lists. Some materials are on all lists, others on only one. Always check the following lists:

  • Section 172.101: Hazardous Materials Table.
  • Appendix A to Section 172.101: List of Hazardous Substances and Reportable Quantities.
  • Appendix B to Section 172.101: List of Marine Pollutants.

I'm not sure if they'll ask about this or not, but just remember that number 172.101. If you see anything on the test about these lists, that number will be the key to identifying the answer.
