Dear Mr. Anderson:

This responds to your November 3, 2009 letter regarding the exceptions for limited quantities of compressed gases under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if a metal container filled with a liquefied compressed gas (LPG) designed to expel a non-poisonous paint for air brush painting kits may utilize the exception in § 173.306(a)(3). The container would contain a flammable compressed gas propellant but would not contain the corresponding liquid, paste, or powder.

The exception in § 173.306(a)(3) is limited to aerosol containers not exceeding one liter capacity in which one or more gases are used to expel other material that is a liquid, paste or powder. An LPG packaged without a liquid, paste, or powder in the container, is not eligible for the exception.

I hope this answers your inquiry. If you have further questions, please do not hesitate to contact this office.
