Dear Mr. Frerichs:

This responds to your November 19, 2001 letter requesting additional clarification of our response letter Ref. No. 01-0280 regarding segregation requirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  Specifically, you ask whether a dromedary unit that is attached to a Heavy Expanded Mobility Tactical Truck with a Load Handling System (HEMTT-LHS), equipped with a flatrack with cargo, is considered to be a separate transport vehicle from the dromedary box.  You intend to transport incompatible explosives separated in this manner.

It is the opinion of this Office that a dromedary box loaded with explosives attached to a HEMTT-LHS that also has a flatrack loaded with explosives is considered to be one transport vehicle, and, is not acceptable for hazardous materials, including incompatible explosives, that may not be transported on the same transport vehicle under § 177.848. However, if the flatrack loaded with explosives is loaded onto a separate trailer attached to the back of the HEMTT-LHS, the combination motor vehicle is considered to be two separate transport vehicles, and is acceptable for hazardous materials that require segregation of incompatible explosives on the same transport vehicle.

I hope this additional clarification on transporting incompatible explosives is helpful.

Sincerely,

 

Delmer F. Billings
