Ref. No. 12-0139

Dear Sergeant Wagner:

This responds to your June 19, 2012 request for clarification on prohibited placarding under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you asked if a red "N" on a white square on point background shown in your attached photographs constitutes a prohibited sign under § 172.502(a)(2).

Section 172.502(a)(2) provides that: [N]o person may affix or display on a packaging, freight container, unit load device, motor vehicle or rail car"any sign, advertisement, slogan (such as "Drive Safely"), or device that, by its color, design, shape, or content, could be confused with any placard prescribed in this subpart.

This prohibition is intended to limit the potential dilution of hazard communication provided by the appropriate hazardous materials placards. The display in the photographs you provided is similar in "shape" (square on point configuration) to that of hazardous materials placards, and could be confused with prescribed placards in the HMR. Therefore, the red "N" on a white square on point background is prohibited under § 172.502(a)(2).

I hope this answers your inquiry. If you need additional assistance, contact this office at (202) 366-8553.
