Proper Tagging

Every sling must include a tag. ASME B30.9 requires all slings to include identifiable and proper tags. Riggers should always reference the details of the tag before use and during inspection. For this reason, the tags need to always remain legible and easily identifiable on the sling. Additionally, a tag should never be used as an attachment point. Depending on the sling type, there are different requirements that must be featured on the tag. Learn more about the requirements for each sling:
