Dear Dr. Verma:
This is in response to your letter regarding the classification of gas samples (blast furnace and coke oven gas) in a 1 liter "Tedlar" gas sampling bag, enclosed in a cardboard mailing tube or box. I apologize for the delay in responding and hope it has not caused any inconvenience.

Specifically, you asked whether the above-mentioned gas mixtures are flammable or nonflammable, and what UN numbers, labeling, and shipping restrictions apply.
You did not provide sufficient information on these materials to make a determination regarding classification. Under 49 CFR 173.22, it is the shipper's responsibility to properly classify a hazardous material. This office does not perform that function.
The requirements for shipping hazardous materials (e.g., gas samples) are found in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). A list of suppliers is enclosed. The HMR address requirements for classification, packaging, preparation of shipping papers, marking, labeling, placarding, emergency response information, and training.
The definitions for a Division 2.1 (flammable) gas and a Division 2.2 (non-flammable) gas are located in § 173.115. Packagings for both Division 2.1 and 2.2 are found in § 173.302. You may wish to have these gas mixtures tested in a laboratory to determine their proper classification.
I hope this information is helpful. If we can be of further assistance, please contact us.
Sincerely,
Delmer F. Billings
Chief, Regulations Development
