No.: 09-0223\nDear Mr. Wright:\nThis responds to your facsimile letter regarding the correct identification number under the\nHazardous Materials Regulations (HMR; 49 CFR Parts 171-180) for a shipment of fully\ncharged \"Amerex Model 600, Halon 1211 Flightline Wheel Units\" from NAS in Corpus\nChristi, Texas to JRB in Fort Worth, Texas.\nAccording to your letter, \"Flightline Wheel Units\" are DOT 4BW240 specification cylinders,\nmaintained by your organization, and placarded with the identification number \"UN1956\"\n(containing Halon 1211 + N2). The MSDS uses the identification number \"UN 1974.\" You\nask for guidance in determining the correct identification number to use to ship these\ncylinders.\nYou did not provide sufficient information (e.g., hazard characteristics, MSDS, etc.,) on your\nproduct to enable us to make a determination regarding classification. Under 49 CFR\n173.22, it is the shipper's responsibility to properly classify a hazardous material. This office\ndoes not perform that function. Under the HMR, the UN numbers \"UN1956\" and \"UN1974\"\nare the identification numbers for the descriptions \"Compressed gas, n.o.s., 2.2\", and\n\"Chlorodifluorobromomethane, 2.2\" or \"Refrigerant gas, R 12B 1\", respectively.\nThe HMR specify requirements for classification, packaging, preparation of shipping papers,\nmarking, labeling, placarding, emergency response information, and training. The definition\nand packaging requirements for compressed gases are found in 49 CFR 173.115 and 173.302,\n\n<<<PAGE 2>>>\n\nrespectively. A list of commercial suppliers ofthe HMR is enclosed.

These wheel units are DOT 4BW240 spec. cylinders. I have\nheld maintenance on these units and as per regs. have placarded them as UN1956 (Halon 1211\n+ N2). All of the MSDS's that have been found use UN1974 in section 14 of the sheet which\nis the Transport Information Section. Supply Department will not ship because of the\ndifference in UN numbers. Can you please me specific guidance? It seems to me that\nsense BOTH are division 2.2 gases they could be shipped under the division code.\nViR\nDavid A.
