What action must be performed to platform and rigging before hoisting personnel after repair?

• A. Proof test to 125% of rated capacity
• B. Visual inspection only
• C. Lubrication
• D. Repaint

Answer: (A)

After repairing a personnel platform and its rigging, you must perform a proof test to 125% of the rated capacity before hoisting people. This test puts a load higher than the normal working load to verify there are no hidden defects and that the critical components—structure, anchors, hooks, cables, and rigging—can carry the stress safely. The goal is to confirm the system has an adequate safety margin and will perform under load without deformation or failure.

Visual inspection alone can miss internal or load-induced problems that only appear under actual load or dynamic conditions. Lubrication and repaint don’t assess strength or integrity; they’re maintenance tasks and don’t prove the equipment can safely support personnel. Hence, the proof test is the necessary step.
