What general requirement ensures no release under normal transport conditions?

• A. They must be designed, tested, properly filled, and closed to prevent release
• B. They must be color coded
• C. They must be vented
• D. They must be stamped with hazard code

Answer: (A)

Preventing a release during normal transport hinges on packaging that can retain its contents. The general requirement is that hazardous material packaging be designed to withstand the stresses of transport, tested to verify its integrity, properly filled to the specified capacity, and closed so that seals and closures remain secure. When these elements are in place, the packaging resists leaks and spills under normal conditions, even with vibration, temperature changes, and stacking. Features like color coding and hazard stamping aid safety and recognition, and venting is used only when specific materials require pressure relief; they do not by themselves guarantee containment.
