Ref. No. 10-0075
Dear Mr. Pace:
This responds to your April 14, 2010 request for clarification ofthe Hazardous Materials Regulations
(HMR; 49 CFR Parts 171-180). Your scenario involves a flatbed trailer with mUltiple pallets ofnonbulk
packages (e.g., 5 gallon pails) that have been individually shrink wrapped and properly secured
to a transport vehicle. Specifically, you ask whether the requirements in § 172.516 are met ifthe
required placards (adhesive backed) are placed on the shrink wrapped pallets so that the placards are
visible from all four sides ofthe transport vehicle.
The required placards may be attached or affixed to the load ofpackages instead ofthe truck itself.
However, the shipment must conform to all the display and visibility requirements. Each placard
must be readily visible from the direction it faces except when the vehicle is attached to another
motor vehicle (§ 172.516(a». The required placards must be securely attached or affixed to the load
of packages, and they must be located clear of appurtenances and devices (e.g. ladders, pipes, doors,
and tarpaulin). The placards must also be affixed to a background of contrasting color or have a
dotted or solid line outer border which contrasts with the background color (§ 172.516(c).
I hope this answers your inquiry. If you need additional assistance, please contact this Office.
Sincerely,
~~

Mr. Mazzullo,
Please except this letter as my request for an interpretation of49CFR 172.516 (Visibility and Display of
Placards). Specifically, I'm requesting clarification on the use of placards on shrink wrapped pallets of
non-bulk packages on a flat bed to meet the transport vehicle placard requirements.
The scenario is, a flatbed trailer with multiple pallets of non-bulk packages (5 gallon pails for example)
which have been individually shrink wrapped and are properly secured on the transport vehicle. Would
the requirements of 172.516 be met ifthe required placards (adhesive backed) were placed on the shrink
wrap of pallets in a manner where placards are visible from all four side of the transport vehicle?
There is no specific reference to this scenario in 172.516 (c) and it would seem as though the intent of the
rule would be met when a transport vehicle had been placarded in the method described.
Your assistance is greatly appreciated.
Sincerely,
Wes Pace
