Dear Mr. Parks:
This responds to your letter dated May 19, 2005, requesting clarification of the classification procedures for aerosols under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask whether an aerosol that does not meet the definition of a Division 2.1 or 2.3 material, or any other hazard class, and does not exert in the packaging an absolute pressure of 280 kPa (40.6 psia) or greater at 20 °C (68 °F), should be classed as a Division 2.2 material.
The answer is no. If a material does not meet the definition of a hazard class or division, and is not a hazardous substance or hazardous waste, it is not regulated under the HMR. See § 173.115(b)
I trust this satisfies your inquiry. Please contact us if we can be of further assistance.
Sincerely,
Hattie L. Mitchell
Chief, Regulatory Review and Reinvention
