5. An exception to the shipper's certification requirement is when the __________

• A. package is provided by the carrier.
• B. shipper is a private carrier transporting a product for another company.
• C. both A and B
• D. neither A nor B

Explanation:
When the shipper packages hazardous materials, he/she certifies that the package has been prepared according to the rules. The signed shipper's certification appears on the original shipping paper. The only exceptions are when a shipper is a private carrier transporting their own product and when the package is provided by the carrier (for example, a cargo tank). Unless a package is clearly unsafe or does not comply with the HMR, you may accept the shipper's certification concerning proper packaging. Some carriers have additional rules about transporting hazardous materials. Follow your employer's rules when accepting shipments.
