Dear Mr. Christafore:
This responds to your March 3, 2015. e-mail requesting clarification on the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to life-saving appliances.
In your e-mail, you describe a small cylinder carrying "UN1072, Oxygen, compressed," a
Division 2.2 compressed gas, which you have suggested could be incorporated in an
"oxygen box assembly" for purposes of use on a passenger aircraft, and subsequently re-
classified as "UN3072, Life-saving appliances, not self-inflating," a Class 9 hazardous
material. You have also provided a schematic diagram of the assembly. Your questions are
paraphrased and answered as follows.
Q1. Can compressed oxygen contained in a cylinder manufactured according to DOT-SP
14399 and incorporated in the above described assembly be re-classified as "UN3072, Life-
saving appliances, not self-inflating"?
Al. Under § 173.22, it is the shipper's responsibility to classify a hazardous material. This
Office does not normally perform this function. However, based on the information
provided, it is the opinion of this Office that the assembly could be re-classified as
"UN3072, Life-saving appliances, not self-inflating" provided that the assembly as
configured during transportation is intended to perform a life-saving function.
Q2. You state that the cylinder, which would form part of the life-saving appliance, is
manufactured according to a special permit (i.e., DOT-SP 14399). Is the shipper required to
identify the special permit on the outer package and prepare copies of the special permit for
the carrier?
A2. Yes. Section 172.301(c) requires the outside of each package authorized by a special
permit to be durably marked "DOT-SP" followed by the special permit number assigned.
The special permit in question does not waive this requirement. In addition, under
§ 173.22a(c), "...the offeror shall furnish a copy of the current exemption or special permit
to the carrier before or at the time a shipment is tendered." Further, in DOT-SP 14399,
paragraph 10, modal requirements, states, "A current copy of this special permit must be
carried aboard each cargo vessel, aircraft or motor vehicle used to transport packages

covered by this special permit. The shipper must furnish a copy of this special permit to the
air carrier before or at the time the shipment is tendered."
Compressed oxygen contained in a cylinder manufactured according to DOT-SP 14399
would need to comply with the provisions under § 173.302(f)(3), (4), and (5) (Thermal
Resistance Test, Flame Penetration Test, and marking requirements) when transported by
aircraft. If a DOT-SP 14399 cylinder containing compressed oxygen is re-classed as
"UN3072, Life-saving appliances, not self-inflating," it would still be required to comply
with § 173.302(f)(3), (4), and (5) as the requirements in § 173.219(b)(1) provide that
"Division 2.2 compressed or liquefied gases must be packed in cylinders in accordance with
the requirements of this subchapter [C]"
I hope this answers your inquiry. If you need additional assistance, please contact this
Office again.
Sincerely
Dirk Der Kinderen
Acting Chief, Standards Development Branch
Standards and Rulemaking Division

Subject: Letter of Interpretation Requested
Good afternoon,
I am in need of some assistance with the possible reclassification of a part. I know that your office does not provide
classifications, but I was hoping that some guidance could be provided.
I have reviewed some other interpretations, but DOT Interpretation Ref No. 00-0028 provided for Essex PB&R
Corporation seems to be the most relevant.
We are currently required to ship small Oxygen, compressed cylinders to customers worldwide.
• The dimensions of the bottle are 9.2" L x 2.75" D
• They are used on aircraft to supply emergency oxygen to passengers in the lavatory and are being used to
replace oxygen generators that were previously installed.
• These cylinders are manufactured under DOT-SP 14399, which is basically a DOT-39 cylinder with some
exceptions.
• When this cylinder is sent separately it is classified as UN1072 Oxygen, compressed.
1. I need to determine, if the same cylinder is attached to a panel, can be reclassified as UN3072 Life-saving
appliances, not self-inflating. (Pictures attached)
2. Also, if acceptable to reclassify as UN3072, since the cylinder is manufactured under a special permit, is
there still a need to identify the DOT-SP 14399 on the outer package and paperwork as required by the
regulations? (UN3072 is not currently an allowable proper shipping name under the terms of the special
permit) Per my understanding there are other life-saving appliances with attached special permit cylinders
that are not required to have the special permit identified.
49CFR 173.219 for Life-saving appliances, allows them to contain 2.2 compressed gases packaged in cylinders that are an
integral part of the appliance and the only reference to size is that the quantities don't exceed those appropriate for the
actual appliance when in use.
In addition to the pictures referenced above, I have also attached details and drawings for the part.
