Lincoln Park, MI 48146 : Deax Dx. Verma: •panese - This is in response to your letter xegarding the classification "Tedlax" gas sampling bag, enclosed in a cardboard mailing tube ot gas samples (blast fuxnace and coke oven gas) in a 1 liter ox box. I apologize for the delay in responding and hope it has The average pexcent composition of these gases is as follows: Gases Blast furnace das Coke even gas Hydzogen 6 - 8% 55 - 60₴ Oxygen 18 Nitxogen 45 - 55₴ Methane 1% 4 - 5* CO 25₴ 18 - 22% 4 - 57 CO2 19 - 20% Ethylene ‹ 1% Ethane 2% < 1% 1% Specifically, you asked whether the above-mentioned gas mixtures axe flammable or nonflammable, and what UN numbers, labeling, and shipping restrictions apply. You did not províde sufficient information on these materials to make a determination regarding classification. Undex 49 CER hazardous matexial. 173.22, It is the shipper's responsibility to properly classify a This office does not perform that function. The requirements for shipping hazardous materials (e.g., gas 49 CER Paxts samples) are found in the Hazaxdous Materials Regulations (HMR; 171-180). A list of suppliers is enclosed. Ihe HMR address requirements for classification, packaging, preparation of shipping papers, marking, labeling, placarding, emergency response information, and training.#

I hope this information is helpful. If we can be of further sincerely, Delmex F. Billings Office of Hazardous Materials Standards Chief, Regulations Development Enclosure#

Mazzullo, Director, Haz Met Standards Department of Transportation, Dear Mr. Mazzullo We are specializing in analysis of blast furnace gas and coke oven gas (classified as manufactured gases). We are trying to look into a possibility to do it by mail where industrial clients shall fill gas sample in 1 liter Tediar gas sampling bag, enclose it in a cardboard mailing tube or box and call UPS to pick up Although sample can reach by ground but we prefer to receive it by airmail overnight so that results are faxed the next day. The gas is filled under a low pressure of 2-3psi. The average percent composition of these gases is as follows: Blast furnace gas Coke oven gas Hydrogen 6 - 8% 55-60% Oxygen 1% 1% Nitrogen 45-55% 4-5% Methane cO 1% 25% 18-22% 4-5% 502 19-20% 3% Ethylene < 1% 2% Ethane < 1% 1% I am told by an expert that manufactured mixed gases like blast furnace gas are nonflammable but 1 need your advise. Which gas mixtures of above are classified as flammable and nonflammable, their UN numbers, labelling and shipping restrictions need to be clearly spelled out. What is required of the clients shipping these samples to us ?. We would need written varliication of solutions to all of the querrles, which can be faxed to us at 313 389 1639. Any relevant published material be malled at above address. Sincerely. SAST Dr. Kuldeop Verma,#
