Dear Mr. Clark:
This responds to your August 2, 2012 request for clarification on the classification of aerosols under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if the proper shipping name, "UN 1950, Aerosols, flammable, n.o.s. (engine starting fluid) (each not exceeding 1 L capacity), 2.1" is used only for engine starting fluid or may it be used with any hazardous material aerosol that contains toluene, acetone, or isobutene.
Section 173.22 states that it is the shipper"s responsibility to properly classify a hazardous material. This office does not perform that function. However, upon review of the information you supplied, it is the opinion of this office, that the most appropriate proper shipping description for aerosols used as engine starting fluid is "UN 1950, Aerosols, flammable, n.o.s. (engine starting fluid), (each not exceeding 1 L capacity), 2.1." There are five different entries in the Hazardous Materials Table (HMT; § 172.101) for UN 1950. Therefore, the most appropriate proper shipping description for aerosols containing toluene, acetone, or isobutene not used as engine starting fluid is "UN 1950, Aerosols, flammable (each not exceeding 1 L capacity), 2.1."
I hope this answers your inquiry. If you need additional assistance, contact this office at (202) 366-8553.
Sincerely,
Robert Benedict
