What is not permitted regarding the complete profile of the C-channel forklift pocket side?

The correct answer is that it's not permitted to have sections cut out of the complete profile of the C-channel forklift pocket side. This is crucial because the structural integrity and load-bearing capacity of the container are highly dependent on the C-channel's design being fully intact. Cutting out sections could weaken the pocket, leading to potential failure during lifting, which poses safety risks and compromises the functionality of the container.

Maintaining the complete profile ensures that the forklift pockets can adequately support the weight of the container during handling and transportation. Any modifications that compromise the design specifications can lead to operational hazards or structural issues, which is why this aspect is strictly regulated.

The other options relate to other forms of alterations or overlaps that may not directly compromise the functional integrity as drastically as cutting out sections. However, maintaining the complete design profile is the priority to ensure safety and reliability.
