How must labels on packages containing hazardous materials be affixed?

Labels on packages containing hazardous materials must be securely affixed to ensure that they remain in place throughout the handling and transport process. This is vital for safety, as the labels provide essential information regarding the nature of the hazardous materials, including risks and handling instructions. A securely attached label minimizes the risk of it becoming detached or obscured, which could lead to dangerous situations if handlers are unaware of the hazards.

The requirement for secure attachment enhances compliance with safety regulations and ensures that emergency responders can accurately identify hazards in the event of an incident. Labels that can be loosely attached, placed on the underside of the package, or that can be interchangeable with other labels do not comply with standard safety practices and could create confusion regarding the materials being handled.
