Rigging equipment like slings, chains, and shackles must be inspected daily for damage or defects and removed from service if unsafe. Proper personal protective equipment should be worn when handling loads. Accidents can occur if loads are not properly secured during lifting or if rigging is overloaded or used at angles that reduce its rated capacity. OSHA regulations specify standards for inspection, maintenance, and use of rigging hardware to prevent injuries and fatalities from falling or shifting equipment.

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.

14. May 2014
• Providence RI
• 8 hurt in fall
• The US Occupational Safety and
Health Administration said the
rigging used put excessive weight
on a carabiner, causing the metal
loop to fail, and the acrobats, who
were hanging by their hair, to fall
15 to 20 feet
• According to OSHA, circus staff
violated both industry practice and
the manufacturer’s instructions for
using the carabiner by attaching it
so it was pulled in three directions,
rather than two.

15. Key Changes in Z359.1
• Section 3.2.1.4
• Gate face strength
requirements have
changed from 220 lbs.
(1kN) (old Standard) to
3,600 lbs. (16kN) (new
Standard).

16. June 2013
• Officials canceled
work on the St.
Charles County
bridge after a 55-
gallon drum being
lifted by a crane fell
on 51-year-old
Jerseyville IL man.
• He was pronounced
dead at the scene.

17. Drums 2015

18. Definitions
• One wire rope lay
1910.184(f)(1)
Sling use. Employers must use only wire-rope slings that have
permanently affixed and legible identification markings as
prescribed by the manufacturer

19. Definitions
Wire rope – consists of many individual wires laid
into a number of strands which are in turn, laid
around a center core.
1910.184(f)(5)(i)
Ten randomly distributed broken wires in one rope lay, or five broken wires in
one strand in one rope lay.

20. Definitions
• Kinked Sling
1910.184(c)(3)
Sling legs shall not be kinked.

21. Definitions
Rated capacity – the maximum allowable working load.

22. Wire Rope

23. Slings• Remove from service
immediately if:
– Acid or caustic burns
– Melting or charring of any
part of the sling surface
– Snags, punctures, tears
or cuts
– Broken or worn stitches
– Distortion of fittings
Not exactly - “If you see red, the
sling is dead.”

24. Synthetic Slings Exercise
5/5/2016 24
1910.184(c)(1)
Slings that are damaged or defective shall not be used

25. Inspection
• Wire rope and synthetic slings
addressed in the B30.9 ASME
standard require:
• 1. Documented periodic
inspection at least annually, but
condition of individual slings not
required. • 9-6.9.3 Periodic Inspection
• (d) Documentation that the most
recent periodic inspection was
performed and shall be maintained.
• (e) Inspection records of individual
slings are not required.

26. Rigging Safety
• Allow for D/d ratio on all wire rope slings.

27. Loss Factor

28. Rigging
• Protect sling from sharp surfaces
• Dekalb accident 1997
• Employees were positioning a 22,000 pound
generator with the use of a truck-mounted
crane and four synthetic web slings.
• While the employees were moving the
generator, the slings contacted a steel purlin
and were cut.
• The generator fell and rolled onto the
employees.
• Employee #1 suffered fatal internal injuries.
• Employee #2 suffered back injuries and was
hospitalized.
• Photo is an example

29. Chain Slings
Only Grade 8 or better Alloy Chain can be used for overhead lifting
purposes! All chain is not rated the same!
Chain must have a capacity tag attached to it.
Chains will withstand more rough handling and abuse, but a chain
with the same rated lifting capacity of wire rope will be much
larger in diameter and heavier in weight

30. Chain Slings 2015

31. Chain Slings
• Four grades:
– Grade 28 General Utility Chain
– Grade 43 High Test Chain
– Grade 70 Binding Chain
– Grade 80 Alloy Steel Chain: The only one used for overhead
lifting
G 80

32. Alloy Steel Chain Slings
• All Slings
Permanently affixed durable
identification stating
• Size
• Grade
• Rated capacity
• Sling manufacturer
• Table H-1 for wear

33. Shackles Pins

34. Shackles
• In rigging applications,
the maximum included
angle at the top, if a
shackle is used would
be:
• 1. 90 Degrees
• 2. 120 Degrees
• 3. 180 Degrees
• 4. 360 Degrees

35. ANSI standards
• ASME non-inspection standards
• ASME B30.5: Mobile and Locomotive Crane
• ASME B30.9: Slings
• ASME B30.10: Hooks
• ASME B30.20: Below-the-Hook Lifting Devices
• ASME B30.26: Rigging Hardware

36. Mar 2014
• Cedar Rapids IA
• Jacob B. "Jake"
Harper, 28, died
Friday after steel
pipes slipped off of a
trailer, struck him
and caused fatal
injuries

37. Summary
• Inspect rigging every day
• Look for 3600 pound gates on caribiners and
Snaphooks
• Protect yourself with PPE
• Develop procedures for unloading.
• Everything should have size, grade and
capacity for rigging.
• Look at rigging angles for loss on slings
