Which of the following is NOT a requirement for securing metal coils during transportation?

The correct answer highlights that stacking coils neatly is not specifically a requirement for securing them during transportation. While it is certainly beneficial for organization and may help avoid shifting, the primary focus of securing methods is to ensure that the coils are properly restrained to prevent movement during transit, which is critical for safety.

Using chains rated for the weight of the coils ensures that the load can be adequately supported and minimizes the risk of slippage or breakage. Utilizing sufficient binding equipment is equally vital, as it prevents the coils from shifting or falling during transit. Regular maintenance of securing systems is necessary to ensure that all equipment is in proper working order, which helps in maintaining safety standards.

While proper stacking may contribute to stability, it does not address the essential safety measures required for the safe transportation of heavy metal coils. Thus, it's not classified as a strict requirement in the context of securing loads.
