Dear Mr. Classic:

This responds to your request concerning your company’s line of restaurant kitchen fire suppression systems. One of the system components is a 4BW cylinder containing potassium carbonate and pressurized with nitrogen to 195 psi. The filled cylinder is packaged and transported as a separate component. You ask if “Nitrogen, compressed, mixture, UN 1066” is the correct shipping name and identification number under the Hazardous Materials Regulations (HMR; 49 CFR, Parts 171-180).

The answer is yes, the proper shipping description for the component is “Nitrogen, compressed, mixture, 2.2, UN 1066.” The potassium carbonate is not a regulated material and is not subject to the HMR. The cylinder must be marked, labeled and packaged as prescribed. You may not take advantage of the exceptions in § 173.309 because the 4BW cylinder is not equipped to function as a fire extinguisher.

I trust this satisfies your request.
