What is the difference between inner packaging and outer packaging?

• A. Inner packaging contains the hazard; outer packaging provides containment and protection.
• B. Outer packaging contains the hazard; inner packaging is for branding.
• C. Both are identical in function.
• D. Outer packaging is only for export shipments.

Answer: (A)

The key idea is how packaging layers work to keep a hazard from leaking and being damaged during transport. Inner packaging is the actual container that holds the material and is designed to keep the hazard contained at the source—it's typically leakproof and compatible with the substance. Outer packaging surrounds that inner container to provide containment and protection during handling and shipment. It catches any potential leakage, shields the inner container from impacts, and gives space for labels and cushioning. An example would be a hazardous liquid placed inside a leak-tight inner container, then placed in a padded outer box with absorbent material to protect against shocks and leaks. The other options don’t fit because the outer packaging alone doesn’t contain the hazard, branding isn’t the purpose, the two packaging levels aren’t identical in function, and outer packaging isn’t only for export shipments.
