- AAny quantity, as it is a "Table 1" hazardous material
- B5,000 pounds (2,268 kg)
- C2,205 pounds (1,000 kg)
- D1,001 pounds (454 kg)
Show answer & explanationAnswer & explanation
Correct answer: D. 1,001 pounds (454 kg)
Division 2.2 materials are considered 'Table 2' hazardous materials. For Table 2 materials, placards are required when the aggregate gross weight of the hazardous material is 1,001 pounds (454 kg) or more.
Why the other options are wrong
- A. Only 'Table 1' hazardous materials require placarding in any quantity.
- B. This weight is a higher threshold sometimes used, but not for general Table 2 placarding.
- C. This weight is relevant for certain specific materials or exceptions, but not the general Table 2 threshold.

For hazardous materials listed in Hazardous Materials Table 2, placards are required on a transport vehicle when the aggregate gross weight of these materials is 1,001 pounds (454 kg) or more.
- Applies to most common hazardous materials.
- Threshold is 1,001 pounds.
- Does not apply to Table 1 materials.
