A tubular welded frame scaffold is 32 feet high. How often must this scaffold be inspected by a competent person?
Correct Answer
C) Daily before each work shift
OSHA requires scaffolds to be inspected by a competent person before each work shift and after any occurrence that could affect structural integrity. Daily inspection is mandatory regardless of scaffold height.
Why This Is the Correct Answer
OSHA 29 CFR 1926.451(f)(3) mandates that scaffolds must be inspected by a competent person before each work shift and after any occurrence that could affect the scaffold's structural integrity. This daily inspection requirement applies to all scaffolds regardless of their height, type, or construction. The competent person must have the knowledge to identify existing and predictable hazards and the authority to take prompt corrective measures to eliminate them. Daily inspections ensure worker safety by catching potential problems before they lead to accidents or structural failures.
Why the Other Options Are Wrong
Option B: Every two weeks
Weekly inspections are insufficient under OSHA standards. Scaffolds face daily wear, weather exposure, and potential damage from construction activities that could compromise safety between weekly checks. OSHA requires more frequent inspection to protect workers from hazards that could develop overnight or during non-work periods.
Option D: Monthly
Monthly inspections do not meet OSHA safety standards for scaffolds. The extended time period between inspections would allow dangerous conditions to persist for weeks, potentially leading to catastrophic failures. OSHA recognizes that scaffold safety requires much more frequent monitoring due to the high-risk nature of elevated work platforms.
Memory Technique
Think 'DAILY DANGER' - scaffolds are dangerous elevated platforms that need DAILY inspection by a competent person to prevent falls and structural failures.
