Specifically, you ask whether the transport vehicle in the photographs provided is subject the placarding requirements of Part 172, Subpart F of the HMR. The answer is no. Provided the permanently mounted propane tanks meet the requirements of 49 CFR 393.65 and 393.67 of the Federal Motor Carrier Safety Regulations (FMCSR) for fuel systems and are used only for supplying fuel for the operation of the motor vehicle or its auxiliary equipment, the mounted propane tanks are not subject to the HMR with respect to their use on the vehicle. I hope this information is helpful. Please contact us if we can be of further assistance.

Avenue SE Washington, DC 20590 FROM: Tom Allen 1 <<>> SUBJECT: General Manager KASI Infrared C orporation 931 John Stark Highway . Newport, NH 03773 Request for determination of placarding We have periodically been asked by customers if placarding and hazmat certification was required on this equipment. In each instance we called you folks and were told that as long as the fuel tanks meet FMCSA 49 CFR 393.65 and.67 regulation as the fit for this equipment and that the tanks were permanently mounted and for the sole purpose of powering the truck mounted equipment that no placarding was required. The key points we were referred to were that this is a permanently mounted system with permanently affixed tanks ;md the propane vapor was utilized solely for the operation of the system. We have two tank configurations depending on the amount of fuel necessary for operation of the systems. The smaller systems carry five 100 LB DOT Multi-Valve LPG Vapor Draw Tanks and the larger systems carry two 420 LB DOT Multi-Valve LPG Vapor Draw Tanks. We would like to have an interpretation to make certain we are Correct regarding placarding. I have attached photos of the systems referred to above Thank you 2 <<>> <<>> ## Provenance - Official: Yes - Source: - Source ID: `phmsa` - SHA-256: `6a6f887150c96d0c2f7ac8ba912916a7c5c79bbdf8777717d45d2daecdf6b587` - Retrieved: 2026-08-20T00:59:31.977Z - Exported: 2026-08-22T14:58:08.686Z - Document slug: `phmsa-interpretation-18-0086` ### Source metadata ```json { "materialSubtype": "interpretation", "interpretationArea": "hazardous_materials", "representation": "full_text_from_official_pdf", "companies": [ "KASI Infrared Corporation" ], "individuals": [ "Tom Allen" ], "refIds": [ "18-0086" ], "catalogDates": [ "2018-09-20" ], "catalogParts": [ 172 ], "catalogRowCount": 1, "sourceRecordUrls": [ "https://www.phmsa.dot.gov/node/70876" ], "linkedAttachmentUrls": [], "unavailableResponseUrls": [], "duplicateRepresentationUrls": [], "citedSections": [], "catalogPageUrls": [ "https://www.phmsa.dot.gov/regulations/title49/part/172" ], "pdfUrls": [ "https://www.phmsa.dot.gov/sites/phmsa.dot.gov/files/docs/standards-rulemaking/hazmat/interpretations/69251/180086.pdf" ], "representations": [ { "viewUrl": "https://www.phmsa.dot.gov/sites/phmsa.dot.gov/files/docs/standards-rulemaking/hazmat/interpretations/69251/180086.pdf", "detailUrl": null, "detailHtmlPath": null, "pdfUrl": "https://www.phmsa.dot.gov/sites/phmsa.dot.gov/files/docs/standards-rulemaking/hazmat/interpretations/69251/180086.pdf", "pdfArtifactPath": "data/sources/phmsa-interpretations/18-0086-75f11dc0a7.pdf", "pdfArtifactSha256": "dfc7de64a327ece1e7d7cf851e2a3c07e0a0c4ec6772217361d37908778cb4e0", "extractedTextPath": "data/sources/phmsa-interpretations/18-0086-75f11dc0a7.v2.txt", "extractedTextSha256": "cfb29077f569f58c675e377378c10c449ebd6b8fda0e487d52a69692183a5a64", "pageCount": 5, "extractionVersion": 2 } ], "caveat": "Interpretations apply regulations to the facts presented and do not create independently enforceable requirements.", "jurisdiction": "US" } ```
