The inspection should follow a formal written inspection procedure to ensure complete examination:

  1. Clean each chain sling prior to inspection.  Chain that is coated with paint, dirt or oil may hide nicks, gouges or other damage.
  2. Check the identification tag legibility.  Ensure that its serial number, name of manufacturer, size, grade, working load limit and reach correspond to the original Chain Sling Certification when the sling was manufactured.
  3. Measure the reach of sling legs to make sure they correspond to the values stamped on the chain sling identification tag.  If one or more legs are longer, there is a possibility that the sling has been subjected to overloading or excessive wear.
  4. Make a link-by-link inspection of the chain slings for:
    1. Excessive wear.  If the wear on any portion of any link exceeds the allowable wear shown on this table remove from service.
    2. Twisted, bent or cut links.
    3. Cracks in the weld area or any portion of the link.
    4. Nicks or gouges.
    5. Stretched links.
    6. Severe corrosion.<
