(3) Visual Inspection.

(a) Immediately after the trial lift, a visual inspection of the crane, hoist, rigging, personnel platform, and the base support or ground shall be conducted by a competent designated person to determine whether the testing has exposed any defect or produced any adverse effect upon any component or structure.

(b) The inspection shall include, but not be limited to, all wire rope, hooks, brakes, the boom, safety devices, and other mechanical, structural, and rigging equipment.

(4) Any defect found during the trial lift or inspection which creates a safety hazard shall be corrected before hoisting personnel.
