Dear Ms. Giusiana:
This is in response to your letter concerning the applicability of the Hazardous Materials Regulations
(HMR; 49 CFR Parts 171-180) to government contract employees moving hazardous materials on
private property.
You are correct in your understanding that hazardous materials moyed entirely on private property on
roads which do not have public access are not considered in transportation and are not regulated by the
HMR. Section 171.1(b) states that persons under contract with local, state and Federal agencies are
subject to the HMR. The letters of clarification from our office, which you included with your request
(Bonekemper to Williams, 4/26/93 and Kaleta to Denny, 4/23/91), state that shipments are not in
commerce unless they move across or along roads to which the public has access.
I hope this satisfies your request.
Sincerely,
we till

Dear Hattie:
Q1
Under HM 215C toluene diisocyanate (TDI) has been updated to include + in
column one of the 171.101 table.
I understand this is a signal that a shipper is not to change this shipping name
even when in a mixture!. Is this true?
The discussion in HM215C in regards to epichlorohydrin appears to me to state
that this is not the case. I find this confusing and conflicting with
172.101(b)(1).
02
If TDI is mixed into adhesives as part of a formula that ends up as a flammable
mixture would I be required to use the name toluene diisocyanate or could I
use the shipping name adhesives??
We would like a written answer. Thank you once again for your expertise.
