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 whither 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 OXYGEN 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.
