  1. AAt least once a week during use
  2. BBefore each work shift and after any event that could affect its integrity
  3. CAnnually, regardless of usage frequency
  4. DOnly after a major modification
Show answer & explanation

Correct answer: B. Before each work shift and after any event that could affect its integrity

OSHA requires that scaffolds be inspected by a competent person before each work shift and after any occurrence that could affect their structural integrity, such as a storm or impact.

Why the other options are wrong

  • A. Weekly inspections are insufficient; more frequent inspections are required by OSHA.
  • C. Annual inspections are far too infrequent for scaffold safety; daily and event-based inspections are critical.
  • D. While major modifications require inspection, this is not the only time an inspection is needed.

Scaffold Competent Person Inspection

The frequency and triggering events for a mandatory inspection of a scaffold by a competent person.

  • Before each work shift
  • After any event affecting integrity (e.g., storm, impact)
  • Performed by a competent person

Memory trick: Shift start, integrity chart, competent person plays the part!
