How do I replace my chain sling identification tag? One of the frequent issues we see in the field are inelligible or damaged sling tags. This creates a challenge not only for OSHA compliance but for the safety of those using slings due to the printed WLL (working load limits) on each sling. If you have any questions just let us know. Standards: ASME B30.9 Standard OSHA 29 CFR 1910.184
