At what height must fall protection be provided for employees working on walking/working surfaces in construction according to OSHA standards?
Correct Answer
A) 6 feet
OSHA 29 CFR 1926.501 requires fall protection when employees are working at heights of 6 feet or more above a lower level. This is the standard trigger height for most construction activities.
Why This Is the Correct Answer
OSHA 29 CFR 1926.501(b)(1) specifically states that employees on walking/working surfaces with unprotected sides and edges which are 6 feet or more above the lower level must be protected from falling by guardrail systems, safety net systems, or personal fall arrest systems. This 6-foot trigger height is the fundamental standard that applies to most construction activities including roofing, scaffolding, and general construction work. The regulation is clear and consistent across most construction scenarios, making 6 feet the critical threshold that contractors must remember and implement.
Why the Other Options Are Wrong
Option C: 8 feet
8 feet exceeds the OSHA requirement and would leave workers unprotected in the dangerous 6-8 foot range where serious injuries commonly occur
Option D: 4 feet
4 feet is too low and does not meet OSHA's minimum height requirement for fall protection in construction, though it may apply in some specific industrial settings under different OSHA standards
Memory Technique
Think 'SIX FEET = SAFETY SYSTEMS' - both start with 'S' and have the same number of letters, helping you remember that 6 feet triggers the need for safety systems
