What feature distinguishes the handling labels from other labels?

Handling labels are specifically designed to provide crucial instructions on how to safely manage and transport packages containing dangerous goods. This information is vital to ensure that the handlers understand the necessary precautions, storage conditions, and any specific handling techniques to minimize risks associated with the materials. By offering clear guidance, handling labels help prevent accidents, ensuring both safety and compliance with regulatory standards.

The other features mentioned in the options do not uniquely define handling labels. While color-coding can be helpful in identifying different categories of hazardous materials, it is not a distinctive feature of handling labels. Symbols are often used across various labels to communicate hazards but do not specifically denote handling requirements. Finally, including shipping information is common across multiple types of labels and does not serve as a distinguishing factor for handling labels specifically.
