Specifically you ask if a\nDOT-SP 7737-1800 aluminum cylinder may be used as an inner packaging with a 4GV outer\npackaging for \"UN2986, Chlorosilanes, Corrosive, Flammable, n.o.s.\" You state that the\nchlorosilanes can be corrosive to steel, and aluminum has better chemical compatibility for your\napplication.\n49 CFR 173.206 authorizes the use of combination packagings with steel or glass inner\nreceptacles for materials described as \"UN2986, Chlorosilanes, Corrosive, Flammable, n.o.s.\"\nSection 173.206(c) authorizes certain single packagings for these materials except for\ntransportation by passenger aircraft. For PG I liquids, specification or UN standard cylinders,\nexcept Specification 3HT and those prescribed for acetylene, are authorized. For PG II liquids,\nspecification cylinders, except Specification 8 and 3HT cylinders, are authorized.\nEven though the HMR specifies certain packagings, it is the responsibility of the person offering\nthe hazardous material for transportation to ensure that such packagings are compatible with\ntheir lading. This particularly applies to corrosivity, permeability, softening, premature aging\nand embrittlement. Further, packaging materials and contents must be such that there will be no\nsignificant chemical or galvanic reaction between the materials and the contents of the package.\nSee § 173.24(e).\n\n<<<PAGE 2>>>\n\n2\nDOT-SP 7737-1800 aluminum alloy cylinders are authorized for the transportation of any\nDivision 2.1, 2.2, and 2.3, and Class 3 material for which DOT specification 3AL cylinders is\nprescribed or authorized in 49 CFR Part 173. See section 6 of the special permit. As such,\nUN2986, Chlorosilanes, Corrosive, Flammable, n.o.s., may not be offered for transportation or\ntransported in a DOT-SP 7737-1800 aluminum cylinder as an inner packaging of a combination\npackaging or as a single packaging.\nYou may apply to PHMSA for permission to use the non-DOT specification packaging described\nin your request under the terms of a special permit. To apply, you must submit an application to\nthe Associate Administrator for Hazardous Materials Safety in conformance with the\nrequirements prescribed in 49 CFR Part 107, Subpart B. In your application, you must provide\njustification that the packaging design you are considering achieves a level of safety that is equal\nto or greater than that required under the HMR. You may obtain information on the special\npermit application process from our website at http://www.phmsa.dot.gov/hazmat/regs/sp-a, or\nby calling PHMSA's Approvals and Permits Division at (202) 366-4511.\nI hope this satisfies your inquiry. Please feel free to contact us if you need further assistance.\nSincerely,\nDuane A.

(Glass is not desirable for our application.) We believe\nOur concern is the chlorosilanes can be corrosive to steel resulting in corrosion. Our customers\nthat aluminum has better chemical compatibility for our application.\nthe inner package is acceptable in a 4GV outer box for shipping.\nThe request is for a formal interpretation if an Aluminum bottle with DOT SP 7737-1800 cylinder as\nI have outline our complete packaging as part of your interpretation should there be additional\nquestions.\n1.
