In your email, you reference § 173.301(f), which\nincorporates by reference Compressed Gas Association (CGA) publication S-1.1 (2011), and\nthus requires pressure relief devices to comply with the CGA pamphlet on pressure relief device\nstandards.\nWe have paraphrased and answered your questions as follows:\nQ1. You ask whether CG-7 pressure relief valves commonly found on 20, 40, 60, and 100\npound propane cylinders require requalification if they are not used in “industrial motor\nfuel” service.\nA1. The answer is no. Paragraph 9.1.1 in CGA S-1.1 states that CG-7 pressure relief valves\n(other than those used in industrial motor fuel service) shall be replaced or requalified\nwithin 10 years of the valve’s manufacture date. However, § 173.301(f)(1) states that\n“except as provided in paragraphs (f)(5) through (f)(7) and (j) of this section, and\n§ 171.23(a) of this subchapter, a cylinder filled with a gas and offered for transportation\nmust be equipped with one or more pressure relief devices sized and selected as to type,\nlocation, and quantity, and tested in accordance with CGA S-1.1 (compliance with\nparagraph 9.1.1 is not required)1 and CGA Pamphlet S-7 (IBR, see § 171.7 of this\nsubchapter).” As noted in your incoming email, your CG-7 pressure relief valves meet\nthe exception provided by § 173.301(f)(1) of not requiring requalification in paragraph\n9.1.1 of CGA S-1.1.\nQ2. You ask whether PHMSA can provide a definition for “industrial motor fuel.”\n1 https://www.ecfr.gov/current/title-49/part-173/section-173.301#p-173.301(f)(1)\n\n<<>>\n\nA2. While there is no definition for “industrial motor fuel” in the HMR or CGA S-1.1, the\nintent behind paragraphs 9.1.1 and 9.1.2 of CGA S-1.1 was to correspond with National\nFire Protection Agency (NFPA) publication 58, paragraph 5.9.2.14. This paragraph states\nthat “all cylinders used in industrial truck service (including forklift truck cylinders) shall\nhave the cylinder’s pressure relief valve replaced by a new or unused valve within 12\nyears of the date of manufacture of the cylinder and every 10 years thereafter.”\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nEamonn Patrick\nActing Chief, Regulatory Review and Reinvention Branch\nStandards and Rulemaking Division\n\n<<>>\n\n23-0026 Wolcott\nFrom: Foster, Glenn (PHMSA)\nTo: Pollack, Arthur (PHMSA)\nSubject: FW: 49 CFR 173.301(f) - Confirmation\nDate: Wednesday, March 22, 2023 8:37:27 AM\nFrom: INFOCNTR (PHMSA) \nSent: Tuesday, March 21, 2023 10:51 AM\nTo: Dodd, Alice (PHMSA) \nCc: Hazmat Interps \nSubject: FW: 49 CFR 173.301(f) - Confirmation\nHi Alice,\nPlease see the below interpretation request and attached pictures.\nLet us know if you need anything.\nRegards,\n-Breanna\nFrom: Sieloff, Kurt \nSent: Friday, March 10, 2023 4:44 PM\nTo: PHMSA HM InfoCenter \nSubject: 49 CFR 173.301(f) - Confirmation\nCAUTION: This email originated from outside of the Department of Transportation (DOT).
