How many tiedowns are required at a minimum for a secure transport of metal coils?

For the secure transport of metal coils, it is required to use at least one direct tiedown and one indirect tiedown to ensure that the load is adequately secured during transit. This combination of tiedowns provides stability and prevents shifting, which is crucial given the weight and shape of metal coils.

A direct tiedown connects directly to the cargo and anchors the load to the transport vehicle, creating a secure hold. An indirect tiedown, on the other hand, serves as a supplementary measure that helps distribute the load's weight and further minimizes movement. Together, these tiedowns help comply with safety regulations and industry standards, ensuring both the cargo and the surrounding environment are protected during transport.

The other options do not meet the necessary requirements for securely transporting metal coils. Simply having one tiedown at each end may not adequately prevent vertical or lateral movement, while relying solely on two direct ties without an indirect one can compromise load stability. Lastly, stating that no minimum is specified fails to recognize the essential safety measures that must be adhered to in transporting such materials effectively. Therefore, using both a direct and indirect tiedown is essential for safe and compliant transport.
