Ref. No.: 12-0064

Dear Mr. Araniz:

This responds to your February 15, 2012 letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the highway compatibility and segregation requirements for Division 1.1 materials. Specifically, you ask whether "UN0065, Cord, detonating, flexible, 1.1D, PG II" can be transported by highway on the same motor vehicle as "UN0048, Charges, demolition, 1.1D, PG II."
The answer is yes. As provided in § 177.848(d), the highway segregatio

n requirements indicate how hazardous materials must be stored, loaded, or transported in accordance with the Segregation Table. A "*" in the Segregation Table indicates that segregation among different Class 1 (explosive) materials is governed by the Compatibility Table in paragraph (f). Per the Compatibility Table for Class 1 (explosive) materials provided in § 177.848(f), these two hazardous materials are authorized to be transported on the same motor vehicle. Additionally, per the definitions of "Cord, detonating, flexible" and "Detonators" in § 173.59, UN0065 is not defined as a detonator and therefore is permitted to be transported on the same motor vehicle with UN0048.

I hope this satisfies your inquiry. Please contact us if we can be of further assistance.
