What is the cleaning requirement for dry dust that is acceptable for open tops but not for dry-vans?

For open-top containers, the requirement for cleaning dry dust is relatively lenient. These containers are typically designed to carry bulk materials, and a simple dusting or sweeping of the interior may suffice for cleaning. This method ensures that any accumulated dust is removed without the need for extensive cleaning processes, which can be time-consuming and costly.

In contrast, dry vans have different cleaning standards due to their use, which is often for transporting goods like food or sensitive cargo. The cleanliness of dry vans is more critical to ensure that no residues that could contaminate the products are present. Consequently, while open-top containers can manage with just a dust removal process, dry vans require more thorough cleaning protocols, often necessitating a wash, either hot or cold, based on the cargo type previously carried.

This distinction emphasizes the difference in the purpose and expected cleanliness standards for the two types of containers, validating why no repair is an acceptable cleaning standard for open tops but not for dry vans.
