No. 15-0131\nDear Mr. Lepinski:\nThis responds to your letter dated June 24, 2015 requesting clarification of the cylinder\ndesign requirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-\n180). Specifically, you asked whether the requirement found in § 178.71(d)(2) for valves to\nconform to International Organization for Standardization (ISO) 10297 applies to the\n\"pressure relief type seal\" that your company plans to use in the manufacturing of fire\nextinguishing systems with United Nations (UN)/ISO 9809-1 cylinders containing\ncompressed nitrogen.\nThe answer is no. Upon review of the information that you provided with your request, this\nOffice agrees that the \"seal\" you plan to use is not a valve. Therefore, the requirement\nfound in § 178.71(d)(2) for valves to conform to ISO 10297 is not applicable. Please note\nthat there are not any regulations under the HMR pertaining to cylinder \"seals.\"\nFurthermore, § 173.301b, paragraph (b), states that cylinders containing Division 2.2,\nvalve.\"\npermanent gases (e.g., nitrogen) are not required to be equipped with an \"individual shutoff\nIn addition, in a related e-mail sent to PHMSA, you ask whether the proposed UN/ISO\n9809-1 cylinder designs would be in compliance with the HMR. A cylinder that is designed\nand manufactured in accordance with the UN/ISO 9809-1 standard, as described in\n§§ 178.69 through 178.71, would be in compliance with the HMR provided that the design\nqualification testing of the cylinder is observed by a DOT-approved Independent Inspection\nAgency (IIA). The IIA will also select random samples from the production lot and send\nthem to a laboratory designated by the Associate Administrator for verification testing, as\ndescribed in § 178.70(f)(4).\nYou may obtain additional information on the cylinder approvals process from our website\nat http://www.phmsa.dot.gov/hazmat/regs/sp-a/approvals/cylinders, or by contacting the\nPressure Vessels Branch within PHMSA's Approvals and Permits Division at (202) 366-\n4512.\n\n<<>>\n\nIf the proposed cylinders are not in compliance with the HMR, you may need to apply for a\nDOT special permit to use the cylinders described in your request. To apply, you must\nsubmit an application to the Associate Administrator for Hazardous Materials Safety in\nconformance with the requirements prescribed in 49 CFR Part 107, Subpart B. In your\napplication, you must provide justification that the packaging you are considering achieves a\nlevel of safety that is equal to or greater than that required under the HMR. You may obtain\ninformation on the special permit application process from our website at\nhttp://www.phmsa.dot.gov/hazmat/regs/sp-a, or by contacting PHMSA's Approvals and\nPermits Division at (202) 366-4511.\nI hope this answers your inquiry.

The attachment describes the concerns and provides support information.\nFor a little bit of history, on 6-15-'15 we placed a call with the Title 49 Hazardous Materials Information Center and\ntalked with Eileen. She provided the contact information for Mr. Mark Toughiry, and we conducted a conference call\nwith him on 6-16-'15. As the result of this call with Mr. Toughiry, he felt the proposed design would be compliant. We\nasked to receive this in writing, for documenting purposes of our project files. Mr. Toughiry provided your contact\ninformation, and stated to work with you to receive the written statement.\nThank you for your assistance in this matter.\nBest Regards,\nMarinette, WI 54143, USA\nJosh Lepinski / Research & Development Mechanical Engineer / Tyco Fire Protection Products\nTel: +1-715-735-7411 ext. 73739\nThis e-mail contains privileged and confidential information intended for the use of the addressees named above.

We\nare evaluating the possibility of sourcing two different UN/ISO 9809-1 cylinders for Restaurant and Vehicle\nfire extinguishing systems, and filling the cylinders with Nitrogen in Marinette, WI USA. The filled cylinders\ncould then be shipped throughout the world. My plan is to use a non-refillable, pressure relief type seal on\nthe cylinder. The seals are pierced by an external mechanical device to begin operation of the system. The\ncylinders are refillable once the seal is replaced. I would like to propose that this seal type would not qualify\nas a valve, and therefore not need to conform to ISO 10297. Please provide your interpretation on the\nproposed seal type and if it would need to conform to ISO 10297 when used on the UN/ISO 9809-1 cylinder.\nAttached are cylinder and system information for your review.\nOur goal is to be certain of DOT compliance when transporting the proposed pressurized cylinders\nout of Marinette, WI before we begin such an endeavor.\nAs a side note, we have been using the same seal design on DOT 3AA cylinders for many years and it\nhas proven to be very safe and reliable.\nPlease let me know if you need any additional information.\nThank you for your assistance.\nSincerely,\nJosh Lepinski\nOffice: 715-735-7411 x73739\nEmail: jlepinski@tycoint.com\nResearch & Development Engineer\nTYCO FIRE PROTECTION PRODUCTS\n\n<<>>\n\nCylinder #1 Design\n(124\n07-ARET\n13/4-TLNGT\nTechnical requirements\n1.
