Which storage group includes items that must have their own means of initiation?

The correct choice is Group F, as it includes items that require their own specific means of initiation. This means that substances within this group must have individual methods or devices that initiate their hazardous reactions or properties, indicating that they pose a higher risk and necessitate specialized handling and storage procedures to ensure safety. Understanding that these items cannot simply be affected by generic ignition sources is critical for compliance with safety regulations.

Other groups, such as Group G, Group A, and Group J, do not have this specific requirement. They may categorize items based on different criteria related to their hazardous characteristics, but they do not emphasize that each item requires its unique initiation mechanism, which sets Group F apart. Familiarity with these differences is essential for proper transport and management of hazardous materials.
