Dear Ms. Gorsky:
Thank you for your letter dated 14 June 2005 (Reference No. 05-0086), in response to our
request regarding the applicability of HMR 49 CFR Parts 170 - 180 to radioactive articles and
mercury. I have replaced Ron Runkles as the liaison for this issue within NEMA and would like
to verify our interpretation of your answers to the questions Ron posed in his letter to PHMSA
dated 7 April 2005. Would you please review the following example involving products
containing both radioactive materials and mercury and indicate whether our understanding is
correct?
Each article contains 60 mg of mercury, packaged at 12 articles per package for a total of 0.72
grams of mercury per package. Each article also contains radioactive thorium at 24 Becquerels
per article, for a total of 288 Becquerels per package. A typical consignment of 48 such
packages exceeds the activity limit for exempt Class 7, UN2911 consignments.
As provided by Answer A2 of your recent response, the shipper may choose to forgo use of the
non-mandatory exception of § 173.164(e) for mercury contained in manufactured articles (at less
than 1 pound of mercury per package), and may properly mark each package of the consignment
with UN2809. The consignment may be properly transported in compliance with § 173.423 for
multiple hazard, limited quantity, Class 7 materials.
Similarly, if the above consignment were to be shipped by domestic air, the shipper may also
choose to forgo use of the non-mandatory exception of § 173.164(b) for mercury contained in
mercury per package), and mark each package with UN2809. The consignment may be
manufactured articles (at less than 100 mg of mercury per article and less than 1 grarn of
properly transported in compliance with § 173.423, as long as the phrase "limited quantity
radioactive material" appears on the shipping papers per § 172.204(c).

To summarize,
1) If the lighting product contains any mercury and qualifies for the exception frorn the HMR
in 49 CFR 173.164(b) or (e), we may, at our discretion, label each package in such
shipments as, "Mercury contained in manufactured articles, UN2809"; as long as the
shipping requirements for multiple hazard, limited quantity, Class 7 provisions are met.
2) If the lighting product contains any mercury and does not qualify for the exception from the
HMR in 49 CFR 173.164(b) or (e), we must label each package in such shipments as,
"Mercury contained in manufactured articles, UN2809"; again as long as the shipping
requirements for multiple hazard, limited quantity, Class 7 provisions are met.
I would be grateful if you would respond to this letter as soon as it is convenient. I am hoping to
arrange a face-to-face meeting later this summer involving you and me and representatives of the
NEMA companies most affected by DOT's labeling provisions. One of our planned topics of
discussion will be any remaining uncertainty related to the UN 2809 labeling issue, so it would
be helpful to have your answer beforehand. We have more general concerns in this area as well
and look forward to discussing them with you.
Thank you again for your consideration in this matter.
Sincerely,
Mark Kohorst
