Thompson\nHazardous Materials Specialist\nRef. No. 98-0230\nBOC Gases\n600 Union Landing Road\nRiverton, NJ 08077\nDear Mr. Thompson:\nThis is in response to your letter dated August 5, 1998, requesting clarification on the proper\ndescription of your gas mixtures under the Hazardous Materials Regulations (HMR; 49 CFR Parts\n171-180). Specifically, you are requesting clarification on the proper shipping name and identification\nnumber for a mixture of any one or more of the following gases: argon, helium, krypton, neon or xenon\nin oxygen. You ask whether the proper shipping name for your mixtures should be \"rare gases and\noxygen mixtures, compressed, UN 1980\" or \"compressed gas, oxidizing, nos, UN 3156\" when the\noxygen concentration is greater than 23.5%.\nSection 172.101 requires that the closest name for the material compatible with the hazard class of the\nmaterial be used. A mixture containing more than 23.5% oxygen is considered to be an oxidizing gas.\nTherefore, the proper shipping name, \"compressed gas, oxidizing, nos, UN 3156\" is more appropriate.\nI hope this satisfies your inquiry.\nSincerely,\nJah\nelmer F.

What if the\noxygen concentration was greater then 23.5%, would it then be described as\nCompressed gas, oxidizing, N.O.S., UN 3256?\nIn the Hazardous Materials Table you have Carbon dioxide and oxygen mixtures,\ncompressed listed with Special Provision 77, which requires you to add a subsidiary\noxidizer hazard label when the oxygen concentration is greater then 23.5% would\nnot or could the same be applied to the Rare gases and oxygen mixtures, compressed\nentry?\nWe want to insure that we are properly labeling these cylinders in compliance with\nthe regulations.
