Which condition would NOT likely lead to the condemnation of a chain sling?

Minor rusting is typically not a condition that would lead to the condemnation of a chain sling, provided it does not affect the overall integrity and functionality of the sling. Some level of surface rust can occur during regular use, especially when a chain sling is exposed to moisture or a corrosive environment. Minor rust can often be addressed through cleaning and maintenance, ensuring the sling remains safe and effective for use.

In contrast, conditions like heat damage, cracked links, and stretching can significantly compromise the strength and safety of a chain sling. Heat damage can alter the material properties, weakening its load-bearing capacity. Cracked links indicate failure in the chain's structure, making it unsafe for lifting tasks. Stretching suggests that the sling has been subjected to loads beyond its designed capacity, risking failure during use. Therefore, these conditions would likely result in condemnation to prevent potential accidents.
