What is a DOT Label?
Labels are pictograms that indicate the Hazard Class or
Division of the hazardous material in a package, covering both the primary
hazard and any subsidiary hazards. Some labels also include special
instructions, such as the "Cargo Aircraft Only" Label.
The regulations include specific pictograms and
colors for each Label. The full text of the requirements can be found in 49 CFR Part 172
Subpart E.
How is a DOT Label Used?
A label is generally applied to non-bulk packages,
such as compressed gas cylinders and fiberboard boxes. Placards are utilized
for bulk packages, such as shipping containers.
When applying a DOT label, it is important that it must
be visible and is not covered up by any other labels that get applied to the
package. It is also important that any designs on the box cannot be confused
with the DOT label. Therefore, it is best that hazardous materials are shipped
in plain containers without any printed patterns.
If multiple DOT labels are needed, such as a package with
both a Hazard Class label and "Cargo Aircraft Only" label, the labels
must be placed next to each other, not overlapping, on the same side of the
package.
What is the Difference Between OSHA and DOT Labels?
OSHA also has separate labeling requirements for packages
containing hazardous chemicals related to workplace safety. These include the
GHS pictograms, which are different than the DOT pictograms.

Labels versus DOT Labels.
