Reference No. 22-0106

Dear Mr. Prevosti:

This letter is in response to your October 6, 2022, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to prohibited display of placards. Specifically, you ask whether a flip placard displaying "blank" white panels constitutes prohibited placarding in accordance with § 172.502(a)(2). When turned to the "blank" side, a flip placard maintains the square-on-point design (i.e., shape of a placard) but does not display any hazard communication information.

The answer is no, display of a "blank" white flip placard does not constitute prohibited placarding. Similarly, an empty placard holder frame also does not constitute prohibited placarding.

I hope this information is helpful. Please contact us if we can be of further assistance.

Sincerely,

Dirk Der Kinderen
Chief, Standards Development Branch
Standards and Rulemaking Division

172.502(a)(2)
