Who must inspect a scaffold before each work shift and after any occurrence that could affect its structural integrity?

A competent person must inspect the scaffold and its components for visible defects before each work shift and after any occurrence that could affect structural integrity. The term is defined and has two halves: capable of identifying existing and predictable hazards, AND authorised to take prompt corrective action to eliminate them. The second half defeats (b) - a trained user can recognise a cracked plank and cannot order the scaffold out of service. The erector (a) may well be the competent person, but the duty attaches to the role rather than to whoever assembled it, and the inspections continue long after the erector has left. A qualified person (c) is a different defined term, reserved for design work such as a scaffold over 125 feet or a suspension system.
