Dear Mr. Bartley:
This responds to your July 11, 2012letter requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to marking requirements
for cargo containers. Specifically, you state that your company ships refrigerated cargo in
reefer containers. The reefer containers have safety markings (as pictured in your letter) on
the back door of the container to provide guidance to equipment users. These marking are
generally placed on the container by the manufacturer and have been noted on similar reefer
equipment used by other container carriers. You ask if these markings would be a violation
of§ 172.502(a)(2).
The answer is yes. Displaying or affixing a sign, advertisement, slogan, or device on a
transport vehicle or freight container that, by its color, design, shape, or content, could be
confused with, or mistaken for, a hazard warning label or placard is prohibited under
§§ 172.401(b) and 172.502(a)(2)) of the HMR. This prohibition is intended to limit the
potential for dilution of hazard warning communication provided by the appropriate
hazardous materials labels and placards. It is the opinion of this Office that the marking
pictured in your letter is not sufficiently distinct from a placard referenced by the HMR.
Therefore, this logo is prohibited under the provisions of §§ 172.401(b) and 172.502( a)(3 ).
I hope this satisfies your inquiry. Please contact us if we can be of further assistance.
Sincerely,
~,#~~

Re: 49CFR172.502(a)(2)- Prohibited Placarding
Dear 1t1r Betts,
Our Company, Horizon Lines, LLC, is a domestic ocean container water carrier who ship
containerized cargo to offshore domestic locations. We also ship refrigerated cargo in reefer
containers that have safety markings on the back door of the container to provide guidance to the
equipment user. The markings are generally placed on the container by the manufacturer and
have been noted on similar reefer equipment used by other container carriers.
Please provide guidance on whether the marking are a violation of 49CFR172.502(a)(2).

Refrigerated contairrcrs or reefer~ rarely carry hazardous cargo so I have placed an Oxidizer
placard on the back of a reefer container to illustrate the differences in the two attachments. The
text on the marking is illegible at a distance of about 15 feet.
Thank you for taking the time to provide guidance on this question.
Sincerely,
