Thompson Hazardous Materials Specialist BOC Gases P.O. Drawer No. 272 : Riverton, NJ 08077 Dear Mr. Thompson: This is in response to your letter of April 17, 1998, requesting clarification of the placarding requirements for oxygen under the Hazardous Materials Regulations (HMR; 49 CFR parts 171- 180). Specifically you ask whether you may display the identification number for oxygen on an OXYGEN placard in lieu of the text. : The answer is yes. As provided by § 172.334 no person may display an identification number on a RADIOACTIVE, EXPLOSIVES, DANGEROUS or subsidiary hazard placard. It is acceptable to display an At GEN placard bearing an identification number on a bulk packaging containing oxygen. The apparent conflict with § 172.519(b)(3), which states that text is required on an OXYGEN placard, will be addressed in a future rulemaking. I hope this information is helpful. - Sincerely, !
