29 CFR 1926.753 Hoisting and rigging
Rigging and hoisting of steel members and materials are essential parts of the steel erection process. However, in
addition to the dangers usually associated with cranes and derricks, steel erection also presents specialized
hazards, such as the use of cranes to hoist employees, suspend loads over certain employees, and
perform multiple lifts. Because of the specialized nature of these hazards, the
provisions below are intended to supplement, rather than
displace, the requirements of 29 CFR 1926.550, the OSHA standard covering cranes and derricks in general
construction.
- Before each shift, cranes being used in steel erection activities must be
visually inspected by a competent person. The inspection must include
observation for deficiencies during operation, including, at a
minimum [29 CFR 1926.753(c)(1)(i)]:
- lubricants,
- water, or
- other foreign matter.
- safety devices, including but not limited to:
- boom-angle indicators,
- boom stops,
- boom kick-out devices,
- anti-two block devices, and
- load moment indicators where required [29 CFR 1926.753(c)(1)(i)(C)];
- air, hydraulic, and other pressurized lines, especially
those that flex during operation, for:
- hooks and latches for
- wire rope reeving for compliance with hoisting equipment manufacturer's
specifications [29 CFR 1926.753(c)(1)(i)(F)];
- electrical apparatus for:
- hydraulic system for proper fluid level [29 CFR 1926.753(c)(1)(i)(H)];
- tires for proper inflation and condition [29 CFR 1926.753(c)(1)(i)(I)];
-
ground conditions around the hoisting equipment for:
- proper support, including ground settling under and around outriggers,
- ground water accumulation, or
- similar conditions [29 CFR 1926.753(c)(1)(i)(J)];
- the hoisting equipment for level position [29 CFR 1926.753(c)(1)(i)(K)]; and
- the hoisting equipment for level position after each move and
setup [29 CFR 1926.753(c)(1)(i)(L)].
- If any deficiency is identified, an immediate determination must be
made by the competent person as to whether the deficiency constitutes a
hazard [29 CFR 1926.753(c)(1)(ii)].
- If the deficiency is determined to constitute a hazard, the hoisting
equipment must be removed from service, until the deficiency has been corrected
[29 CFR 1926.753(c)(1)(iii)].
- A qualified rigger (a rigger who is also a qualified person) must inspect the rigging prior to each shift in accordance with
29 CFR 1926.251 [29 CFR 1926.753(c)(2)].
|
- Routes for suspended loads must be preplanned to ensure that no
employee is required to work directly below a suspended load, except for [29 CFR 1926.753(d)(1)]
 :
- When employees work under suspended loads, the following criteria must be
met [29 CFR 1926.753(d)(2)]:
|
- A multiple lift may be performed only if the following criteria are
met [29 CFR 1926.753(e)(1)]:
- Multiple-lift rigging assembly capacity, for the total assembly and for each individual attachment point, must:
- be certified by the manufacturer or a qualified rigger,
- be based on the manufacturer's specifications, and
- have a 5-to-1 safety factor for all components [29 CFR 1926.753(e)(2)].
- The total load must not exceed:
- The multiple-lift rigging assembly must be rigged with members:
- The members on the multiple-lift rigging assembly must be set in position from the
bottom up [29 CFR 1926.753(e)(5)].
- Controlled load lowering must be used whenever the load is over the
connectors [29 CFR 1926.753(e)(6)].
|
Commercially manufactured lifting equipment designed to lift and
position a load of known weight to a location at some known elevation and
horizontal distance from the equipment’s center of rotation.
A "come-a-long" (a mechanical device usually consisting of a
chain or cable attached at each end, that is used to facilitate movement
of materials through leverage) is not considered "hoisting
equipment."
