Dear Mr. Morenz:

This responds to your August 27, 2009 letter regarding the definition of an aerosol in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171"180). Specifically, you ask if a metal container filled with a liquefied compressed gas but without the corresponding liquid, paste, or powder, can be defined as an aerosol.

The answer is no. In accordance with § 171.8, an aerosol means any non-refillable receptacle containing a gas compressed, liquefied or dissolved under pressure, the sole purpose of which is to expel a nonpoisonous (other than a Division 6.1 Packing Group III material) liquid, paste, or powder and fitted with a self-closing release device allowing the contents to be ejected by the gas. Also see related §§ 171.23(b)(1) and 173.306(a)(3).

I trust this satisfies your inquiry. Please contact us if we can be of further assistance.
