What does 49 CFR 178.33a-5 (Material) require?

Short answer

49 CFR 178.33a-5 requires uniform quality steel plate or nonferrous metal of uniform drawing quality for the material, and prohibits material with seams, cracks, laminations, or other injurious defects.

The rule says

"Uniform quality steel plate such as black plate, electrotin plate, hot dipped tinplate, ternplate or other commercially accepted can making plate; or nonferrous metal of uniform drawing quality." (49 CFR 178.33a-5(a))

"Material with seams, cracks, laminations or other injurious defects not authorized." (49 CFR 178.33a-5(b))

In plain English

This rule is about the material used to make inner nonrefillable metal receptacles, which are used to transport hazardous materials. The material must be of high quality and free from defects that could cause it to fail during transportation.

What to do

• Verify that the material used for the receptacle meets the requirements of 49 CFR 178.33a-5.
• Check for any defects in the material, such as seams, cracks, or laminations.
• Ensure that the receptacle is made from uniform quality steel plate or nonferrous metal of uniform drawing quality.
• Keep records of the material used and the inspections performed to ensure compliance with the regulation.
