What is the recommended action for transferable burn marks that could damage dry-van cargo?

Power sanding the marks is recommended as it effectively removes transferable burn marks that can potentially damage dry-van cargo. Burn marks can create a surface that might stick to or mar the cargo inside the container, leading to significant issues for the cargo integrity. By power sanding these marks, the surface can be restored, reducing the risk of cargo damage. This action helps ensure that the container is in an optimal condition for transporting goods, which is crucial in maintaining cargo quality and minimizing liability.

In contrast, the other options do not adequately address the risks posed by burn marks. For instance, stating that no repair is necessary overlooks the potential harm to cargo. Ignoring minimal damage could lead to bigger issues down the line if the damage, while appearing minor, affects the cargo. Replacing the floor is an excessive measure that typically wouldn’t be warranted for just burn marks, especially since power sanding can achieve a suitable repair without the need for significant changes or expenses.
