Dear Dr. Wians:

This responds to your letter regarding the applicability of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if the HMR apply to the manual (non-motorized) transfer of infectious substances between two contiguously located medical facilities.

The HMR do not apply to the rail and motor vehicle movement of a regulated hazardous material exclusively within a contiguous facility boundary where public access is restricted. Moreover, the HMR only apply to the movement of hazardous materials transported by rail car, aircraft, motor vehicle, or vessel in commerce. Because the manual (non-motorized) transfer of infectious substances between two contiguously located medical facilities does not fall into either category, such transfers are not subject to the HMR.

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