Scaffolding must be inspected by a competent person at which intervals according to OSHA standards?
Correct Answer
D) Daily before each work shift
OSHA requires scaffolding to be inspected by a competent person before each work shift and after any occurrence that could affect structural integrity, such as high winds, heavy rains, or impacts.
Why This Is the Correct Answer
OSHA 29 CFR 1926.451(f)(3) specifically requires that scaffolds be inspected by a competent person before each work shift and after any occurrence that could affect the structural integrity of the scaffold. This daily inspection requirement ensures worker safety by identifying potential hazards before workers begin using the scaffold. The competent person must have the training and experience to recognize scaffold hazards and the authority to take corrective action.
Why the Other Options Are Wrong
Option A: Monthly and after severe weather
Inspecting scaffolds only when initially erected is completely inadequate for worker safety. Scaffolds are subject to daily wear, weather conditions, impacts, and other factors that can compromise their structural integrity. Ongoing daily inspections are essential to identify developing problems.
Option B: Only when initially erected
Monthly inspections are far too infrequent for scaffold safety. OSHA recognizes that scaffold conditions can change rapidly due to weather, use, and other factors, requiring daily inspection before each shift. Monthly intervals would leave workers exposed to undetected hazards for extended periods.
Option C: Weekly and after any occurrence that could affect structural integrity
While weekly inspections might seem reasonable, OSHA requires more frequent inspections - specifically before each work shift, not just weekly. The 'after any occurrence' part is correct, but the weekly interval is insufficient for ensuring daily worker safety on scaffolds.
Memory Technique
Think 'SID' - Scaffold Inspection Daily. Just like you check your tools before starting work each day, scaffolds need that same daily attention from a competent person.
