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.

Do Chain Slings Need to Be Load Tested After a Repair Has Been Performed?

Do Chain Slings Need to Be Load Tested After a Repair Has Been Performed?

Chain SlingXavier, a salesperson for a CMCO distributor, asks the following question:
“I am doing some research on the guidelines and laws concerning repairs made to chain slings. I found some very conflicting information from OSHA and ASME. To summarize, ASME states that chain slings do not need to be load tested after a repair has been performed. OSHA says that new and repaired chain slings must be load tested before being returned to service. I was hoping to get your opinion and maybe Columbus McKinnon’s official stance on this issue.“

Peter Cooke, CMCO Training Manager, answers:
Thank you for reaching out to us with your concern. This is a great question. If the chain is a welded assembly (only certain companies are authorized to do this) and a welded link was repaired, then the sling needs to be load tested. If the sling is made up of mechanical components and those components have been individually load tested by the manufacturer, no load test needs to be done.

For example, I have a single-leg sling and I replace the top oblong link. The oblong link is connected with a mechanical coupler, such as a Hammerlok, and has been tested by the manufacturer. Under these conditions, I do not have to load test the sling, but I would recommend inspecting the sling, link by link, to be sure all components are safe to use per ASME B30.9 and OSHA 1910.184.

Missing Chain Sling ID Tags: Who Is To Blame?

Missing Chain Sling ID Tags: Who Is To Blame?

missing chain sling ID tagsJason asks:

Who is responsible for putting tags on chain slings?  Can I retag my chain slings with missing tags?  Do I have to load test a sling after I retag it?

Peter answers:

It is the sling manufacturer’s responsibility.  The sling manufacturer is a person or company assembling or fabricating sling components into their final form.  The sling manufacturer and the manufacturer of the sling materials may or may not be identical.  An end user who buys components and assembles them mechanically is the sling manufacturer. If the user does not know who the sling manufacturer is because the old tag fell off and went missing, then a decision needs to be made.  It is the user’s or rigger’s responsibility to maintain the tag and be sure it remains legible.  A rigger can not use a sling without a tag or when a tag is illegible or missing information.

Replacing missing chain sling ID tags becomes a question of competency.

Can the user properly inspect and retag the sling? For retagging, the user would need to start his own serial number for documentation purposes.  In doing so, this user would become the “sling manufacturer.” This can only be done if the user is properly trained and deemed competent.  Per OSHA,  a person who tags a sling must be a competent person designated by the employer.  ASME B30.9 states: replacement of the sling identification shall be considered a repair.  Slings shall be repaired only by the sling manufacturer or a qualified person. A repair shall be marked to identify the repairing agency. To be considered competent and or qualified, the user should have some inspection experience and complete a rigging gear inspection course from a reputable training organization.

If the user feels they are not competent to properly inspect and retag the sling, they would need to send the sling out to a rigging house with a competent person for inspection and retagging.  That rigging house now becomes the “sling manufacturer.”  Tags must have information per OSHA 1910.184(e) Alloy steel chain slings.  I have noted the key points below referencing both OSHA and ASME standards:

missing chain sling ID tags

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

ASME B30.9:  SECTION 9-1.7: Sling Identification
9-1.7.1 Identification Requirements

Each sling shall be marked to show:
(a) name or trademark of the manufacturer
(b) grade
(c) nominal chain size
(d) number of legs
(e) rated loads for the type(s) of hitch(es) used and the angle upon which it is based
(f) length (reach).

A load test is not required if a sling is made up of individual load tested components from the component manufacturer. If the sling is always found in acceptable condition per ASME B30.9, OSHA 1910.184 and manufacturers’ recommendations, then the sling can remain in service without ever needing another load test performed.

Is it Possible to Mix Chain Grades on a Sling?

Is it Possible to Mix Chain Grades on a Sling?

mixing chain gradesBen from Chicago asked the following question about mixing chain grades:

Is it possible to mix grade 80 chain and grade 100 components on a sling assembly?

Peter answers:

In simple terms, yes –  BUT the assembly can only be rated at the grade 80 WLL.  Here is an example:  A sling is made with grade 100 chain and the hooks used for the sling are grade 80. This sling would need to have a tag with a grade 80 working load limit (WLL) of the weakest component.

For your reference I have provided the following applicable standards:

ASME B30.9, 9-1.5.7

When components of a sling have a lower rated load than the alloy chain with
which it is being used, the sling shall be identified with a rated load consistent
with the lowest load rating of any of the components.

OSHA 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.
