In-Depth Alloy Chain Sling Inspection Part 5: OSHA Chain Sling Inspection

In-Depth Alloy Chain Sling Inspection Part 5: OSHA Chain Sling Inspection

This article is Part 5 of a 5-part blog series that will cover what professional riggers should consider when performing an in-depth alloy chain sling inspection. Today, we’ll discuss OSHA chain sling inspection regulations and guidelines.

Since first published on July 27, 1975, the OSHA Chain Sling Inspection section has undergone very few changes. These regulations have and continue to serve as a comprehensive guide for those responsible for chain sling inspection.

Chain SlingSpecifically, the applicable sections of the Code of Federal Regulations (29 CFR 1910.184) include:

1910.184(d) Inspections
Each day before being used, the sling and all fastenings and attachments shall be inspected for damage or defects by a competent person designated by the employer. Additional inspections shall be performed during sling use, where service conditions warrant. Damaged or defective slings shall be immediately removed from service.

1910.184(e) Alloy steel chain slings

1910.184 (e)(1) Sling identification
Alloy steel chain slings shall have permanently affixed durable identification stating size, grade, rated capacity, and reach.

1910.184(e)(2) Attachments

  • 1910.184(e)(2)(i)
    Hooks, rings, oblong links, pear shaped links, welded or mechanical coupling links or other attachments shall have a rated capacity at least equal to that of the alloy steel chain with which they are used or the sling shall not be used in excess of the rated capacity of the weakest component.
  • 1910.184(e)(2)(ii)
    Makeshift links or fasteners formed from bolts or rods, or other such attachments, shall not be used.

1910.184(e)(3) Inspections

  • 1910.184(e)(3)(i)
    In addition to the inspection required by paragraph (d) of this section, a thorough periodic inspection of alloy steel chain slings in use shall be made on a regular basis, to be determined on the basis of (A) frequency of sling use; (B) severity of service conditions; (C) nature of lifts being made; and (D) experience gained on the service life of slings used in similar circumstances. Such inspections shall in no event be at intervals greater than once every 12 months.
  • 1910.184(e)(3)(ii)
    The employer shall make and maintain a record of the most recent month in which each alloy steel chain sling was thoroughly inspected, and shall make such record available for examination.
  • 1910.184(e)(3)(iii)
    The thorough inspection of alloy steel chain slings shall be performed by a competent person designated by the employer, and shall include a thorough inspection for wear, defective welds, deformation and increase in length. Where such defects or deterioration are present, the sling shall be immediately removed from service.

Please note that while the requirements under (d) for daily inspections are not explicit as to scope or maintenance of records, it is possible that individual OSHA inspectors may have different views on conformity. However, the minimum 12-month interval inspections required under (e) call for thorough inspection and written records. It is this thorough type of inspection that the procedures recommended in our Rigging Catalog and CMCO Training Classes are designed to satisfy.

Of course, the fundamentals are equally applicable to the more cursory daily inspections made by riggers, users or inspectors (individuals deemed a “competent person”) and will enable them to fulfill their responsibility efficiently.
