Dear Mr. Beavers:

This is in response to your letter dated March 30, 1999 concerning the technical name(s) requirements for a gas mixture as required by the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  You describe the mixture as "Compressed gas, n.o.s., 2.2, UN195611 and supply a material safety data sheet (MSDS) which includes ratios of the various gases which make up the mixture.  You ask for guidance in determining which components in the mixture would be listed as technical names.

Section 172.203 (k)(2) requires the technical names of at least two components most predominately contributing to the hazards of a mixture or solution which contains two or more hazardous materials be included in the shipping description.  In your scenario, the MSDS which you included lists oxygen and nitrogen as the two main components of the mixture.  While the mixture also contains small amounts of hydrogen sulfide and carbon monoxide, which are both Division 2.3 materials, the mixture is classified as a Division 2.2 material.  The technical names must identify the components which predominately contribute to the hazards the material exhibits, which was have determined to be Division 2.2. Thus, the technical names would be oxygen and nitrogen.

I hope this satisfies your request.

Sincerely,

Transportation Regulations Specialist
Office of Hazardous Materials Standards

172.203
