- C5,000 lbs
- D500 lbs
Show answer & explanationAnswer & explanation
Correct answer: C. 5,000 lbs
For Division 1.4 (Explosives) materials, a special routing or escort is not required if the aggregate gross weight of the explosives does not exceed 5,000 lbs. Above this limit, specific routing and escort requirements may apply.
Why the other options are wrong
- A. This limit is incorrect; it's often associated with other hazardous materials for placarding thresholds.
- B. This limit is too high for Division 1.4 materials without special routing/escort.
- D. This limit is too low for Division 1.4 materials.
