19. 1405 Disassembly
(c) None of the pins ( top or bottom) on boom sections located between the uppermost boom section and the crane body are to be removed( partly or completely) when the boom is being supported by the uppermost boom section resting on the ground

24. On March 17, 1997, a 42-year-old master mechanic was fatally injured while dismantling a crane boom (The victim and two coworkers were dismantling the crawler-mounted lattice boom crane in preparation for transport. The crane boom had been lowered to 8½ feet off the ground and was supported by the boom pendants. The victim positioned himself under the pinned connections between the inner (heel or base) section and the center section of the boom. The victim removed the pins from the bottom connections. When the victim removed the last of the two pins, the boom sections fell, striking and pinning the victim underneath [NIOSH 1997].

74. Riggers “the other third of safe crane operation”

75. Rigging Precautions Most important
Determine the weight of all loads before attempting to lift them.
When assessment of the weight is difficult, weighing devices should be attached to the rigging equipment.
Rig the load so that it is stable and that the center of gravity is below the hook.
Tell the operator the weight of what he is picking prior to making the lift

76. Rigging Precautions
5. Ensure that the safe working load of equipment is not exceeded if it is exposed to wind.
6. Avoid sudden snatching, swinging, and stopping of suspended loads. Rapid acceleration and deceleration greatly increases the stress on equipment and tackle.

77. Care of Slings
The useful life and safety of slings can be increased by following these suggestions:
Kinked or damaged slings or hoist ropes should never be used.
All slings and fittings should be inspected before every use for signs of wear, abrasion, broken wires, worn fittings, loose seizings and splices, kinking, crushing, corrosion, and flattening.

78. Damaged wire rope

79. Care of Slings
Slings should have an identification number or a size and their maximum capacity listed on a flat ferrule or ring that is permanently attached to the sling.
The rated capacity for each type of hitch should be listed. If a choker is missing this tag, it must be destroyed immediately.
If it is a larger (more expensive) piece of rigging it can be retagged.
