Dear Mr. Neitzel:
stamping and approval of Multiple-element gas containers (MEGC) under § 178.74 of the
This is in response to your request for a clarification of the requirements applicable to the
Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, your inquiry
concerns allowable pressure receptacle specifications fitted within a MEGC framework
manufactured in the United States after January 1, 2007.
In the scenario provided in your letter, you state that a MEGC has an attached data plate
displaying both the United Nations (UN) stamp and the "USA" mark, and that the MEGC has
been approved by an Independent Inspection Agency (IIA).
Your questions are paraphrased and addressed as follows:
Q1.
Can the MEGC described above be fitted with dual stamped and approved DOT-
and "USA" markings. Additionally, this arrangement has not been previousl
T/ISO 11120 pressure receptacles that are not additionally stamped with the "UN'
approved by the Associate Administrator as an "Alternative Arrangement."

The answer is no. In accordance with § 178.71(o), the UN symbol and the mark of the
country where the approval is granted must be marked on each UN pressure

country of approval in conformance with §§ 178.69 and 178.70. This requirement

A2.
The definition of a "multiple-element gas container," in § 171.8, references "UN
cylinders, tubes, or bundle of cylinders." DOT specification cylinders or tube are
not included.
I hope this information is helpful.

Subject: Request for Interpretation Concerning Stamping and Approval of MEG's
Dear Mr. Mazzullo:
I am requesting a written interpretation concerning allowable pressure receptacle
specifications fitted within a MEGC framework manufactured in the United States after
January 1, 2007. The MEGC has an attached dataplate displaying both the UN stamp of
approval and the "USA" mark, and has been IIA approved.
Specifically, I am requesting clarification if such an MEGC may be fitted with dual
tamped and approved DOT-3T/ISO 11120 pressure receptacles which are no
dditionally stamped with the UN stamp of approval and the "USA" mark if thi
arrangement has not been previously approved by the Associate Administrator as an
Alternative Arrangement.
In addition, I am also requesting clarification if the definition for a "multiple-element
gas container" as written in 49CFR § 171.8 specifically prohibits the use of DOT
specification cylinders or tubes" within a MEGC:
