Dear Mr. Erdheim:
This is in response to your January 28, 2005 letter regarding
the applicability of the Hazardous Materials Regulations (HMR;
49 CFR Parts 171-180) to radioactive articles and mercury. Your
questions concern lamps that contain both mercury and limited
quantity radioactive materials. Your scenarios and questions
are paraphrased and answered as follows:
Q1. Is an excepted package for a radioactive article subject to
the multiple hazard limited quantity requirements in § 173.423
if the package contains less than a pound of mercury and is
transported by highway?
Al. No. As indicated by the letter "A" in Columr 1 of the
Hazardous Materials Table (HMT), "Mercury contained in
manufactured articles", UN 2809, is subject to the HMR when
meets the definition in S 171.8 for a hazarcous substance or
transported by aircraft. It is regulated by highway only when it
hazardous waste. Mercury has an RQ of one pound. Therefore,
since your package contains less than one pound of mercury and
is not a hazardous
waste, it is only subject to the HMR for the
radioactive material.
an excepted package for a radioactive article subject to
the multiple hazard
limited quantity requirements in § 173.423
if it has a presence of mercury with
a net weight of less than
100 mg per article and one gram per package for an air shipment?

A2. No.
A package containing the amount of mercury described
package is only subject to the HMR for the radioactive material.
is not subject to HMR (see § 173.164 (b)). Therefore, your
I hope this information is helpful.

Dear John:
The National Electrical Manufacturers Association (NEMA) represents manufacturers of
lamps. Some lamps contain both mercury and limited quantities of radioactive material.
With reference to the new RSPA regulations dealing with use of the UN2911 label, there
has been discussion in the industry as to how to apply this new requirement to
commercial use. We have the following questions regarding interpretation of USDOT
regulations, pertaining to the domestic ground and domestic air transportation of lamps
containing both of these materials.
Pursuant to 49 CFR 173.2a (a), these lamps must be classified as Class 8 - Corrosive.
Therefore, they are subject only to the requirements of 49 CFR 173.424 (a) through (g)
related to packaging.
Based on this interpretation, please answer the following questions:
1. Does a Radioactive material excepted package - article, fall under the requirements
of 173.423 for multiple hazard limited quantity radioactive materials when the second
hazard is the presence of mercury in net package weight of less than one-pound for
highway shipment?
2. Does a Radioactive material excepted package - article, fall under the requirements
of 173.423 for multiple hazard limited quantity radioactive materials when the second
hazard is the presence of mercury in net weight of less than 100 mg per article and one
gram per package for air shipments?

We would appreciate the opportunity to have a conference call between the appropriate
RSPA staff and NEMA lamp manufacturers to discuss these issues. We will contact you
to set up such a call.
Thank you for your attention.
