What must be included in the design of outer packaging for transport?

The design of outer packaging for the transport of dangerous goods is critical for ensuring safety, compliance, and protection during transit. The requirement that it must be weatherproof and impact-resistant is particularly important because outer packaging is responsible for shielding its contents from environmental factors and physical impacts that may occur during handling and transportation.

Weatherproofing ensures that the packaging can withstand exposure to moisture, temperature fluctuations, and other environmental conditions, which is essential for preventing leaks or degradation of the hazardous materials inside. Impact resistance is equally crucial, as it protects against physical shocks, drops, or collisions that might occur during loading, unloading, or transport.

In contrast, while factors like being lightweight or disposable might be beneficial for general transport considerations, safety and security take precedence for dangerous goods. Also, the aesthetic aspect of bright colors does not contribute to the protective qualities required for packaging hazardous materials. Therefore, the emphasis on weatherproof and impact-resistant packaging aligns with the regulatory standards and safety principles needed for transporting dangerous goods effectively.
