Mazzullo,\nDirector, Haz Met Standards\nDepartment of Transportation,\nDear Mr. Mazzullo\nWe are specializing in analysis of blast furnace gas and coke oven gas (classified as\nmanufactured gases). We are trying to look into a possibility to do it by mail where\nindustrial clients shall fill gas sample in 1 liter Tediar gas sampling bag, enclose it in\na cardboard mailing tube or box and call UPS to pick up Although sample can reach\nby ground but we prefer to receive it by airmail overnight so that results are faxed the\nnext day. The gas is filled under a low pressure of 2-3psi.\nThe average percent composition of these gases is as follows:\nBlast furnace gas\nCoke oven gas\nHydrogen\n6 - 8%\n55-60%\nOxygen\n1%\n1%\nNitrogen\n45-55%\n4-5%\nMethane\ncO\n1%\n25%\n18-22%\n4-5%\n502\n19-20%\n3%\nEthylene\n< 1%\n2%\nEthane\n< 1%\n1%\nI am told by an expert that manufactured mixed gases like blast furnace gas are\nnonflammable but 1 need your advise. Which gas mixtures of above are classified as\nflammable and nonflammable, their UN numbers, labelling and shipping restrictions\nneed to be clearly spelled out. What is required of the clients shipping these samples\nto us ?. We would need written varliication of solutions to all of the\nquerrles, which can be faxed to us at 313 389 1639. Any relevant\npublished material be malled at above address.\nSincerely.\nSAST\nDr. Kuldeop Verma,","truncated":false,"body_characters":3537}
