Is it true that higher packing group numbers indicate greater chemical danger?

Is it true that higher packing group numbers indicate greater chemical danger?

• A. True
• B. False
• C. Not Determined
• D. Depends on substance

Answer: (B)

Packing Groups are used to indicate how hazardous a material is for transport, and the numbering is arranged so that Group I is the most dangerous, Group II is moderately dangerous, and Group III is the least dangerous. A higher number does not mean greater danger; it means less danger. So a highly hazardous substance would be placed in Group I, while a less hazardous one would be in Group III. This is why the statement is false: danger increases with a lower packing group number, not a higher one.
