What does "over-packaging" mean in the context of dangerous goods?

In the context of dangerous goods, "over-packaging" refers to placing a larger container around packages of dangerous goods for added protection. This practice is crucial for ensuring the safe transportation of hazardous materials, as it enhances the structural integrity and safety of the contents. Over-packaging helps to prevent leaks, spills, or contamination during transport, which is vital given the potential risks associated with dangerous goods. By using a larger container, the items can be better secured, and any potential hazards can be mitigated, protecting both the transport personnel and the environment.

In contrast, using multiple layers of packaging to confuse authorities does not align with safety protocols and could lead to compliance issues. Transporting goods without proper labeling is also not permissible, as all dangerous goods must be clearly marked to inform handlers and responders of the materials being transported. Lastly, minimizing the use of space in a transport vehicle does not directly relate to the safety of handling dangerous goods and is more of a logistical consideration rather than a safety one. Thus, the notion of adding a larger protective layer through over-packaging is essential for ensuring safety and regulatory compliance.
