Derricks
Derricks present unique safety hazards to workers that are addressed in Section 1436.
In general, all provisions of the standard apply to derricks unless Section 1436 specifies different or additional requirements.
Operator Qualifications
Derrick operators need not meet the operator qualification/certification requirement of section 1427. However, you must train each derrick operator on how to operate the equipment safely.
Load Charts
For permanently installed derricks with fixed lengths of boom, guy, and mast, a load chart must be posted where it is visible to personnel responsible for the operation of the equipment. For derricks that are not permanently installed, the load chart must be readily available at the job site to personnel responsible for operating the equipment. Load charts must contain at least the:
- rated capacity at corresponding ranges of boom angle or operating radii
- specific lengths of components to which the rated capacities apply
- required parts for hoist reeving
- size and construction of rope (or may be included in the operating manual)
