Dear Mr. Deveaux:

This is in response to your letter and subsequent telephone conversation with a member of my staff requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) with regard to the requirements for the proper orientation of labels on packagings containing hazardous materials.  Your understanding of the terms, “diamond (square-on-point)” in the HMR and "set at an angle of 450" in the International Civil Aviation Organizations Technical Instructions for the Safe Transport of Dangerous Goods by Air, is that they do not have the same meaning.

The terms  “a 45 degree angle” and diamond (square-on-point)”  are synonymous and refer to the orientation of the label design for the placement of the pictorial symbol, text, class or division number and compatibility group.  Section 172.406 addresses the placement of labels on packages.  The HMR do not prohibit the placement of hazard warning labels in an orientation where the square-on-point is located with its flat sides parallel to the sides of the packages.  The labels may be placed square-on-side when square-on-point is not practicable.

I hope this information is helpful.  Please contact us if you have additional questions.
