For combination packaging containing liquid dangerous goods, what orientation requirement must be observed?

• A. Closures oriented upright and orientation labels indicated
• B. Closures oriented sideways and orientation labels placed on exterior
• C. Orientation is optional for all packaging
• D. Labels may be applied without considering orientation

Answer: (A)

Keeping liquids in combination packaging upright is essential because liquids can leak or slosh if the package is not kept in the correct orientation. The outer packaging must have its closures oriented upright, and an orientation label must be affixed to the exterior to indicate the required upright position. This helps handlers and transport personnel maintain the proper orientation throughout loading, transit, and unloading, reducing the risk of leakage and exposure. The other options fail because sideways orientation is not acceptable, orientation is not optional, and simply applying a label without conveying the correct upright position does not meet the requirement.
