Departmen f Transportation 400 Seventh Street, S.W Washington, D.C. 20590 Pipeline and Hazardous Materials Safety Administration NOT 11 Mr. Edward O'Brien Reference No.: 05-0266 Fire Protection Certification 8719 Pete Wiles Road Middletown, MD 21769 Dear Mr. O'Brien: This responds to your letter concerning the cylinder requalification marking requirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask it a pressure sensitive label displaying the requalification markings may be ›laced on the sidewall of a composite (fiber wrapped) cylinder used as a fire extinguisher. Section 180.213(c)(1) authorizes a cylinder used as a fire extinguisher to be marked by using a pressure sensitive label. It is permissible to place the label on the sidewall of a cylinder. Stamping the markings on the cylinder sidewall or any part of the fiber wrapped surface is prohibited. I trust this satisfies your request. Sincerely, Hattie L. Mitchell Chief, Regulatory Review and Reinvention Office of Hazardous Materials Standards BUT HAH 180.213 050266#

Section 180.2130 (1) states, a cylinder used as a fire extinguisher may be marked using a pressure sensitive label. It has been the practice that fiber wrapped cylinders when requalified are marked with a label that is affixed to the cylinder sidewall and epoxied. The request for interpretation is, does the prohibiting of sidewall marking such as fire extinguishers and fiber wrapped cylinders can be placed on the side apply to stamping of a cylinder only and that labels attached to requalified cylinders wall of these cylinders?. Sincerely Scondo Broni Edward O'Brien#
