SafetyCâu 652 / 700
Who must inspect a scaffold for visible defects, and how often, before it is used?
a.Any available worker, once a week
b.A licensed engineer, once at erection only
c.The scaffold manufacturer, monthly
d.A competent person, before each work shift and after any event that could affect its structural integrity
Giải thích
Correct: a competent person must inspect the scaffold before each work shift and after any occurrence (such as a storm or being struck) that could affect structural integrity. A weekly check by any worker, a one-time engineer inspection, or monthly manufacturer visits all miss the required per-shift, competent-person inspection that catches loose planks, damaged parts, and settlement.
