DC 20590 of Transportation Pipeline and Hazardous M.aterials Safety Administration JAN 192012 Mr. Marty Beyer Quality Analyst Chart Industries lric. 1300 Airport Drive Ball Ground, GA 30107 Ref. No.: 11-0144 Dear Mr. Beyer: This responds to your initial July 1,2011 request and subsequent July 13, 2011 email seeking clarification of the requirements in the International Air Transport Association's (IA TA) Dangerous Goods Regulations and the Hazardous Materials Regulations (HMR; 49 C.F.R. Parts 171-180). As information, the lATA regulations do not have official standing under the HMR. The regulations recognized by the HMR and conditionally authorized for use in § 171.22 are the International Civil Aviation Organization's (ICAO) Technical Instructions. Since the 2011-2012 edition of the ICAO Technical Instructions includes the same Packing Instruction 202, this letter interprets the ICAO provision. Your questions are paraphrased and answered below. Q1. Would the requirements in Packing Instruction 202 for open cryogenic receptacles allow the markings to be engraved or printed on a permanently attached data plate welded to the upper surface ofthe receptacle? A 1. Yes. Package Instruction 202 requires the marks to be "permanently affixed, e.g. by stamping, engraving or etching." Markings on a data plate welded to the upper surface of the receptacle would be considered permanently affixed. Q2. Would the requirements in Packing Instruction 202 for open cryogenic receptacles allow the markings to be on an adhesive label attached to the upper surface ofthe receptacle? A2. Yes. Package Instruction 202 ofthe ICAO Technical Instructions states that the receptacle must be "designed, manufactured, tested and equipped in such a way as to withstand all conditions, including fatigue, to which they will be subjected during their normal use and during normal conditions oftransport." Further, Package Instruction 202 requires that the marks be permanently affixed to the receptacle. While this office generally does not recommend the use ofa label for permanently affixing package markings to a receptacle, provided the label is of a permanent character and affixed in a permanent manner, it is our opinion that affixing a printed label is acceptable. <<>> Q3. Would the requirements in Packing Instruction 202 for open cryogenic receptacles allow the markings to be engraved on a tag that is attached by a cable or short chain to the upper surface of the receptacle? A3. No. It is our opinion that a tag is not affixed to the receptacle. Q4. May open top cryogenic receptacles with free liquid nitrogen in the bottom be shipped under Package Instruction 202 as a dry shipper? A4. No. Section 173.320(a) oftheHMR provides that cryogenic liquids in Dewar flasks designed and constructed so that the pressure will not exceed 25.3 psig under normal ambient temperature conditions when transported by rail and motor vehicle are not subject to the HMR requirements. However, for transportation by aircraft, an offeror must follow all applicable air transportation requirements. Additionally, when transported by aircraft, a dry shipper may not contain any unabsorbed liquid. Q5. When returned empty with some absorbed liquid nitrogen, is the container still considered a dry shipper? A5. Yes. A dry shipper, which is a specially designed Dewar flask that uses nitrogen, refrigerated liquid as a refrigerant, would still be considered a dry shipper if the absorbent material is saturated with nitrogen, refrigerated liquid, with no free liquid present in the packaging. Q6. What is the function of the UN number marking? A6. The UN number is an identification number assigned to each proper shipping name of a material designated as a hazardous material in the HMR or a dangerous good in the ICAO Technical Instructions. A list ofhazardous materials and their identification numbers is located in the Hazardous Materials Table in § 172.101 ofthe HMR, and in Table 3.1 ofthe ICAO Technical Instructions. I hope this answers your inquiry. If you need additional assistance, please contact the Standards and Rulemaking Division at (202) 366-8553.

I was directed David Brennan of lATA that in the US the Pipeline and Hazardous Materials Safety Administration (PHMSA) is the agency that enforce the regulations, and that I should confirm what I propose is acceptable. I work for Chart Inc. in Ball Ground GA. One of our product lines is Cryopreservation Equipment for Transport Systems for Biological Materials (Non pressurized open top cryogenic vessels with non oxidizing refrigerated liquid). After reviewing the responses below I have a couple questions regarding the new 52nd Edition of the lATA Dangerous Goods Regulations, specifically Packing Instructions 202. We manufacture Liquid Nitrogen biological receptacles, and I'm particularly concerned about the NEW requirement Packing Instructions 202 (i) that Open Cryogenic Receptacles must bear the following marks permanently affixed, e.g. by stamping, engraving or etching (model, manufacturer name & address, serial number, capacity, UN number) I would like to get an interpretation of what permanently affixed means. We manufacture aluminum units that are then painted and have a long life adhesive label for identification. The problem lies in the complexities of stamping or engraving the compound curve surface on the top of our units and would like clarification on acceptable alternatives. I would like to have this information so I can direct manufacturing on the correct path. Will it be acceptable to attach to the upper part of the container as an alternate to stamping, engraving or etching: 1 <<>> Engraved aluminum data plate welded on the data plate corners to the upper surface of the units.

My question(s) are the following: * Does this affect units already in the field i.e. will be need to develop a service plan to take units in and alter them with this engraving/stamping, or will they get to be "grandfathered" in? * Does size & location of the engraving/stamping matter? Can we place this information on the outer bottom of the unit (as not to disrupt our paint process)? * Since this is lATA and not DOT, it seems to be an international change only, does that mean we are currently okay in the US? Are there plans to harmonize with DOT? I know this is a lot, but any help would be greatly appreciated!! I believe one of my colleagues, Kevin Thissen, may have already contacted you.

Usa (PHMSA) Subject: Chart - Request For Formal Letter of Interpretation Attachments: MVE Doble Series - catalog page. pdf; MVE Cryro Shipper QWick Series - catalog page.pdf; MVE Doble QWick Series - catalog page.pdf Lisa I thank you for responding back. I am relatively new to this product line and process and I am trying to assist in getting information and interpretations. We are in the process of getting pictures of the different ways to identify the open cryogenic receptacles. Since we were only discussing these other options it will take us awhile to create and get the pictures for you to review. I have attached catalog pages as a representation of the 3 model lines that will probably be affected by the changes on Packaging Instruction 202 In the meantime I have a few other questions for clarification if you could assist us in clarification it would be greatly appreCiated. On our non pressurized open top cryogenic receptacles the MVE Doble Series & MVE Doble QWick Series are mostly used as dry shippers by our customers. The customers add liquid nitrogen into the unit and is absorbed in a hydrophobic compound so the liquid nitrogen is not in a free state. (Dry shipper). My question is some of our customers "top off lithe units with a little free liquid nitrogen in the bottom of the unit to extend the storage time when shipping. Will this still be acceptable under Packaging Instruction 202 as a dry shipper? Or would the unit change category as a Dry shipper to a liquid shipper. Or is there a limit- say only max 2/1 of free liquid in the bottom is acceptable? The next question is when the units need to be returned empty. It may still be cold with some absorbed liquid nitrogen or warm. Would this returning unit be considered a dry shipper or something else like standard freight? This next question came up in discussion and I am a little confused as I have not seen it stated or have missed it in the standard. The question is of the function of the UN number? Is this related to the new labeling or registration # ? Or is it something totally not related. Please assist me and clarify. I look forward to your reply as we looking forward to implement changes to meet the new requirements.
