According to Cal/OSHA Title 8 regulations, scaffolds must be inspected by a competent person at what intervals during construction use?
Correct Answer
B) Before each use and after any occurrence that could affect structural integrity
Title 8 CCR Section 1637 requires scaffold inspection by a competent person before each use and after any occurrence that could affect structural integrity, such as high winds, earthquakes, or impacts. This ensures worker safety by identifying potential hazards before employees access the scaffold system.
Why This Is the Correct Answer
Title 8 CCR Section 1637 mandates scaffold inspection by a competent person before each use and after any occurrence that could affect structural integrity (e.g., high winds, seismic events, collisions, heavy rain). The 'before each use' requirement ensures that conditions that developed overnight, over a weekend, or after any disruption are caught before workers are exposed to the hazard.
Why the Other Options Are Wrong
Option A: Weekly and after any occurrence that could affect structural integrity
Weekly inspection plus post-occurrence checks are insufficient. Weekly intervals could allow multiple days of undetected degradation — loose planks, overloaded tiers, corrosion, or storm damage — to go unnoticed. Cal/OSHA's 'before each use' standard is more stringent.
Option C: Daily before each work shift
'Daily before each work shift' is close but subtly wrong. If a scaffold is used multiple times per day across different shifts, 'daily' could be interpreted as once per day, not once per shift. The precise regulatory language is 'before each use,' which is shift-agnostic and tied to the act of using the scaffold, not a calendar interval.
Option D: Before initial use and after any weather event
'Before initial use and after any weather event' misses the ongoing 'before each use' requirement. A one-time initial inspection plus weather-triggered checks would leave the scaffold uninspected through many normal use cycles. 'Weather event' is also narrower than 'any occurrence that could affect structural integrity,' which includes impacts and loading changes.
Memory Technique
Link scaffold inspections to the phrase 'Never climb without a check.' Before EACH use = before EACH climb. The occurrence trigger is easy: anything that could shake, tip, or stress the scaffold demands re-inspection before the next worker steps on it.
