Prior to initial use, all new and altered derricks shall be inspected to
ensure compliance with the provisions of 1910.181. Inspection is divided into two
categories:
- Frequent - daily to monthly intervals
- Periodic - 1 to 12 month intervals.
All functional operating systems, control systems, safety
devices, chords and lacing, tension in guys, plumb of the mast, air and hydraulic systems,
rope reeving,
hooks, and electrical apparatus shall be visually inspected daily.
Once a month, running ropes shall be inspected and a certification record shall be
completed which includes the inspection date, the inspector’s signature, and the
equipment serial number or other identifier. This certification record shall be kept on
file where it is readily available to appointed personnel.
Complete inspection of the derrick shall be performed at 1 to 12 month intervals depending
on its activity, severity of service, and environmental conditions. The inspection shall
include deformed, cracked, corroded, worn, or loose members or parts. The inspection
should also include the power plant, foundations, and supports. |
