A driver is preparing to transport a shipment of UN1760, Corrosive liquid, N.O.S., Class 8, PG II. What is the maximum number of hazardous materials that can be listed on a single shipping paper?
- ANo more than 5 different hazardous materials.
- BThere is no maximum limit, provided all entries are properly listed.
- CNo more than 10 different hazardous materials.
- DThe limit is determined by the total weight of the shipment.
Show answer & explanationAnswer & explanation
Correct answer: B. There is no maximum limit, provided all entries are properly listed.
Federal Hazardous Materials Regulations (49 CFR) do not specify a maximum number of different hazardous materials that can be listed on a single shipping paper. The key requirement is that each hazardous material entry must be accurately and completely described, and all other shipping paper requirements (e.g., emergency response information, total quantity) must be met.
Why the other options are wrong
- A. Incorrect. There is no such numerical limit specified in the regulations.
- C. Incorrect. There is no such numerical limit specified in the regulations.
- D. Incorrect. The total weight of the shipment affects placarding and other requirements, but not the number of distinct hazardous materials that can be listed on one paper.
Shipping Paper Entries: Quantity of Materials
Hazardous Materials Regulations specify the content and format of shipping papers, but not a numerical limit on how many distinct hazardous materials can be listed on a single document.
- Each hazardous material requires a complete and accurate basic description.
- Emergency response information must be provided for every HazMat.
- Total quantity of each HazMat must be indicated.
- The number of entries is limited only by practical space and clarity.
Memory trick: Many HazMats on one sheet? If clear, it's a treat!
