Dear Mr. Barlen:

This is in response to your letter of July 17, 2000, requesting information on the applicability of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) to DOT specification cylinders for personal use.

As specified in § 17 1. 1, the HMR govern the safe transportation of hazardous materials in intrastate, interstate, and foreign commerce.  Therefore, a DOT specification cylinder used to supply liquefied petroleum gas for cooking and heating at a consumer location, which is filled at that location and never transported in commerce, is not subject to the HMR.  There is no need to remove the specification marking from the cylinder.

For your information, although not required by the HMR, we recommend testing of any cylinder beyond its retest date prior to refilling the cylinder.

I hope this information is helpful.



Edward T. Mazzullo
Director, Office of Hazardous
Materials Standards
