Dear Me. Cooper:
This responds to your March 30, 2011 letter requesting clarification of the Hazardous Materials
Regulations (HMR; 49 CFR Parts 171-180) applicable to marking requirements. Specifically,
you state in your letter that you have designed an orange panel holder to protect orange panels
from damage. You ask whether your orange panel holder is permissible under the HMR so that
you may produce this item for commercial sale.
This Office does not provide approval for comniercial products. However, provided the orange
panel itself meets the identification number marking requirements specified in § 172.332(b), and
the orange panel holder does not prevent the marking from meeting the visibility requirements
specified in § 172.304, the orange panel holder would be permitted to be used under the HMR.
I hope this satisfies your inquiry. Please contact us if we can be of further assistance
Sincerely,
T. Glenn Foster
Chief, Regulatory Review and Reinvention Branch
Standards and Rulemaking Division

Re: New Design Example #2
Mr. Eichenlaub,
We also talked about a new placard holder for the orange panel type placards. There is no holder for
these, they "peel and stick". However, they do not stick if the trailers are dirty, cold or wet. This results in
the same problem we are having with the placards that do have holders. They fly off.
What I came up with is a similar design as the original placard holder taking out the center supports and
changing the frame size to 16 7/8" wide and 10" high, riveting a clear acrylic sheet to the back of the front
of the frame and 2 retainer clips at the top to secure the placard. If the acrylic sheet cracks or needs to be
replaced, simply drill out the rivets and replace. The acrylic can be coated with an anti-fog agent as well
as an anti-scratch agent.
Dimension size for the Orange Panel Placard Holder
Aryclic .080" thick 15 W' wide X 6 % " high
Frame made of .025" thick aluminum 167/8" wide X 7 W' high
Backmount plate .025" thick aluminum 16 7/8" wide X 10" high
Four 1/8" X1/8" aluminum rivets to hold acrylic to frame
Seven 3/16" X1/8" aluminum rivets to hold frame to back mount plate
Two snap retainer clips
Attached are pictures of the prototype for this design.
What I am asking for is a letter of approval so I can go forward with these projects.
If you need more information or specifications, please feel free to contact me bye-mail
