No. 15-0131 Dear Mr. Lepinski: This responds to your letter dated June 24, 2015 requesting clarification of the cylinder design requirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171- 180). Specifically, you asked whether the requirement found in § 178.71(d)(2) for valves to conform to International Organization for Standardization (ISO) 10297 applies to the "pressure relief type seal" that your company plans to use in the manufacturing of fire extinguishing systems with United Nations (UN)/ISO 9809-1 cylinders containing compressed nitrogen. The answer is no. Upon review of the information that you provided with your request, this Office agrees that the "seal" you plan to use is not a valve. Therefore, the requirement found in § 178.71(d)(2) for valves to conform to ISO 10297 is not applicable. Please note that there are not any regulations under the HMR pertaining to cylinder "seals." Furthermore, § 173.301b, paragraph (b), states that cylinders containing Division 2.2, valve." permanent gases (e.g., nitrogen) are not required to be equipped with an "individual shutoff In addition, in a related e-mail sent to PHMSA, you ask whether the proposed UN/ISO 9809-1 cylinder designs would be in compliance with the HMR. A cylinder that is designed and manufactured in accordance with the UN/ISO 9809-1 standard, as described in §§ 178.69 through 178.71, would be in compliance with the HMR provided that the design qualification testing of the cylinder is observed by a DOT-approved Independent Inspection Agency (IIA). The IIA will also select random samples from the production lot and send them to a laboratory designated by the Associate Administrator for verification testing, as described in § 178.70(f)(4). You may obtain additional information on the cylinder approvals process from our website at http://www.phmsa.dot.gov/hazmat/regs/sp-a/approvals/cylinders, or by contacting the Pressure Vessels Branch within PHMSA's Approvals and Permits Division at (202) 366- 4512. <<>> If the proposed cylinders are not in compliance with the HMR, you may need to apply for a DOT special permit to use the cylinders described in your request. To apply, you must submit an application to the Associate Administrator for Hazardous Materials Safety in conformance with the requirements prescribed in 49 CFR Part 107, Subpart B. In your application, you must provide justification that the packaging you are considering achieves a level of safety that is equal to or greater than that required under the HMR. You may obtain information on the special permit application process from our website at http://www.phmsa.dot.gov/hazmat/regs/sp-a, or by contacting PHMSA's Approvals and Permits Division at (202) 366-4511. I hope this answers your inquiry.

The attachment describes the concerns and provides support information. For a little bit of history, on 6-15-'15 we placed a call with the Title 49 Hazardous Materials Information Center and talked with Eileen. She provided the contact information for Mr. Mark Toughiry, and we conducted a conference call with him on 6-16-'15. As the result of this call with Mr. Toughiry, he felt the proposed design would be compliant. We asked to receive this in writing, for documenting purposes of our project files. Mr. Toughiry provided your contact information, and stated to work with you to receive the written statement. Thank you for your assistance in this matter.

Washington, DC 20590-0001 Subject: Interpretation of 49 CFR 178.71 Dear Charles Betts, I, on behalf of Tyco, would like to have an interpretation on the subject par 178.71(d) of 49 CFR. We are evaluating the possibility of sourcing two different UN/ISO 9809-1 cylinders for Restaurant and Vehicle fire extinguishing systems, and filling the cylinders with Nitrogen in Marinette, WI USA. The filled cylinders could then be shipped throughout the world. My plan is to use a non-refillable, pressure relief type seal on the cylinder. The seals are pierced by an external mechanical device to begin operation of the system. The cylinders are refillable once the seal is replaced. I would like to propose that this seal type would not qualify as a valve, and therefore not need to conform to ISO 10297. Please provide your interpretation on the proposed seal type and if it would need to conform to ISO 10297 when used on the UN/ISO 9809-1 cylinder. Attached are cylinder and system information for your review. Our goal is to be certain of DOT compliance when transporting the proposed pressurized cylinders out of Marinette, WI before we begin such an endeavor. As a side note, we have been using the same seal design on DOT 3AA cylinders for many years and it has proven to be very safe and reliable. Please let me know if you need any additional information. Thank you for your assistance.
