The only thing I could find that I think might apply is this:
(d) Functions not subject to the requirements of the HMR. The
following are examples of activities to which the HMR do not apply:
(1) Storage of a freight container, transport vehicle, or package
containing a hazardous material at an offeror facility prior to a
carrier taking possession of the hazardous material for movement in
transportation in commerce or, for a private motor carrier, prior to a
motor vehicle drivertaking physical possession of the hazardous material for movement in transportation in commerce.
(2) Unloading of a hazardous material from a transport vehicle or a
bulk packaging performed by a person employed by or working under
contract to the consignee following delivery of the hazardous material
by the carrier to its destination and departure from the consignee's
premises of the carrier's personnel or, in the case of a private
carrier, departure of the driver from the unloading area.
(3) Storage of a freight container, transport vehicle, or package
containing a hazardous material after its delivery by a carrier to the
destination indicated on a shipping document, package marking, or other
medium, or, in the case of a rail car, storage of a rail car on private
track.
(4) Rail and motor vehicle movements of a hazardous material
exclusively within a contiguous facility boundary where public access is
restricted, except to the extent that the movement is on or crosses a
public road or is on track that is part of the general railroad system
of transportation, unless access to the public road is restricted by
signals, lights, gates, or similar controls.
(5) Transportation of a hazardous material in a motor vehicle,
aircraft, or vessel operated by a Federal, state, or local government
employee solely for noncommercial Federal, state, or local government
purposes.
(6) Transportation of a hazardous material by an individual for non-
commercial purposes in a private motor vehicle, including a leased or
rented motor vehicle.
