Final answer:
Transportation regulations require the use of a securement device, such as a chain or strap, over the top of coil loads like flat rolled steel to prevent shifting during transit, ensuring safety and stability.
Step-by-step explanation:
The question you've asked pertains to the proper securement of coil loads during transportation. It is important to use a securement device such as a chain or strap over the top of coil loads to ensure they do not shift or move during transit, which can be dangerous and cause accidents. This is a requirement stated by transportation regulations and guidelines for load securement, particularly in the trucking and logistics industry.
For example, flat rolled steel coils, which are often transported on flatbed trucks, require adequate securement to maintain stability on the road. Depending on the orientation of the coil (eye horizontal or eye skyward), the securement methods can vary, but all require the use of chains or straps to prevent movement.
