Labeling requirements establish clear and accurate communication about the material in a package. This means that each package must have the specific hazard labels displayed in the chemical table for the appropriate service. These requirements specify the design, size and color of the labels. Hazard labels cannot be bent or wrapped around corners.
Some hazardous materials have multiple risks and require more than one hazard label.
All subrisk labels must be displayed on the same side of the package as the primary label and the associated marking. Their class numbers must be covered. Covering the class number on a hazard label denotes subrisk status. There are exceptions to the hazard labeling requirements. However, you may use the appropriate label to ensure maximum hazard communications, and UPS urges you to do so.
