In your letter, you state that the material is not a\nhazardous material and you provide a safety data sheet as supporting documentation. Further,\nyou state that you would like to transport the liquid material in a non-DOT specification cylinder\ninstead of your current practice of using a 55-gallon steel drum. You note that internationally\nthese cylinders are used to transport pressurized liquified gases such as other fire suppression\nagents. You state that this change in manner of transport is to facilitate filling of the associated\nfire suppression system upon delivery. Specifically, you request confirmation that this shipment\nis not subject to the requirements of the HMR and that the use of these cylinders is permitted.\nIn accordance with § 173.22, it is the shipper s responsibility to properly classify a hazardous\nmaterial. If you have determined that the liquid fire suppression agent is not a hazardous material\nin accordance with applicable HMR criteria, then it is not subject to the HMR and may be\ntransported in the packages you noted without restriction from the HMR.\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nDirk Der Kinderen\nChief, Standards Development Branch\nStandards and Rulemaking Division\n\n<<<PAGE 2>>>\n\nCasey\n23-0032\nFrom: INFOCNTR (PHMSA)\nTo: Hazmat Interps\nSubject: FW: Request for interpretation - Using liquid in gas cylinder\nDate: Friday, March 31, 2023 10:43:15 AM\nAttachments: 926L-6mm cylinder.pdf\nSDS-FK-5-1-12-US-Version-4.1-2021-05-07.doc (5).pdf\nHello,\nPlease see attached and below request for letter of interpretation.\nAlso here is the mailing address:\nMichael Kiamanesh\n2032 Robert Browning St, Austin, TX 78723\n737-999-3367\nThanks,\nJonathon, HMIC\nFrom: Mike Kiamanesh <mike@waysmosusa.com>\nSent: Friday, March 24, 2023 2:03 PM\nTo: INFOCNTR (PHMSA) <INFOCNTR.INFOCNTR@dot.gov>\nSubject: Request for interpretation - Using liquid in gas cylinder\nCAUTION: This email originated from outside of the Department of Transportation (DOT). Do\nnot click on links or open attachments unless you recognize the sender and know the content\nis safe.\nHi DOT,\nI am interested in importing a fire suppression agent that we manufacture called FK-5-1-12 (SDS\nattached), in non-dot approved gas cylinders (drawing of cylinder attached).\nThe molecule FK-5-1-12 as you can see on the SDS is not considered hazmat, right now the most\ncommon way of transporting it is as general cargo in 55 gallon steel drums.\nWhy we want to use the cylinders is because our customers want a larger bulk packaging where they\ndo not need to switch containers (drums) as much when filling their fire suppression system\ncylinders. For reference the drums each hold about 250kg of the FK-5-1-12 while the cylinder we\nwant to use holds 1000kgs.\nThese cylinders are used internationally (not in USA) to bulk transport pressurized liquified gases,\nsuch as another fire suppression agent HFC-227ea. We just want to start using them in the USA for\nmoving this non pressurized non hazmat bulk liquid fire suppression agent.\nLet me know anything else you need from me. I am available anytime for a call as well.\n\n<<<PAGE 3>>>\n\nRegards\nMike\n737-999-3367\n\n<<<PAGE 4>>>\n\nSafety Data Sheet\nSection 1 – Chemical Product and Company Identification\nProduct Name FK-5-1-12\nChemical Name 1,1,1,2,2,4,5,5,5-Nonafluoro-4-(trifluoromethyl)-3-pentanone\nSynonym FLUOROKETONE, Perfluoro(2-Methyl-3-Pentanone), NOVEC1230™\nProduct Use Fire extinguishing agent\nManufacturer Address Shanghai Waysmos Fine Chemical Co., Ltd.\n388 Liangle Road, Laogang, Pudong New Area, Shanghai, China\nEmail sales@waysmos.com\nTelephone +86-571-85069383\nFax +86-571-85069385\nSection 2 –Hazard Identification\nHazard classification This material is not considered hazardous by the OSHA Hazard Communication\nStandard (29 CFR 1910.1200)\nHazard pictograms\nSignal word Warning\nHazard statements Precautionary statements\nOther Hazard H412: Harmful to aquatic life with long lasting effects.\nP261: Avoid breathing vapours.\nP273: Avoid release to the environment.\nP280: Wear protective gloves/protective clothing.\nOverheating and over pressurizing may cause gas release or violent container\nbursting.\nSection 3 – Composition/Information on Ingredients\nIngredient name CAS No. %(weight)\n1,1,1,2,2,4,5,5,5,-Nonafluoro-4-(t\nrifluoromethyl)-3-pentanone 756-13-8 ≥99. 0\nSection 4 – First Aid Measures\nRevision date: May.7,2021 Version 4.1\n1\n\n<<<PAGE 5>>>\n\nSafety Data Sheet\nInhalation\nSkin\nEyes Ingestion Note to physician Remove victim to fresh air and keep at rest in a position comfortable for\nbreathing.\nIf not breathing, if breathing is irregular or if respiratory arrest occurs, provide\nartificial respiration or oxygen by trained personnel.\nIf unconscious, place in recovery position and get medical attention immediately\nRemove and isolate contaminated clothing and shoes.
