What critical information can be found on a sling's identification tag?

The identification tag on a sling provides essential safety information, including the sling's capacity, material, and usage instructions. This information is vital for ensuring that the sling is used correctly and safely. Knowing the sling's capacity helps riggers avoid overloading it, which can lead to failure and accidents. The material information indicates compatibility with various loads and environmental conditions, while usage instructions guide the rigger on how to properly employ the sling in different situations.

Other options do not provide the necessary critical information required for the safe operation of a sling. For instance, while knowing the color of a sling may offer some visual identification, it does not convey any operational or safety details. Similarly, the manufacturer's history or repair instructions alone do not address how the sling should be safely and effectively used in rigging tasks.
