Under OSHA 29 CFR 1926, at what height must fall protection be provided for workers on scaffolds?
Correct Answer
A) 10 feet
OSHA 29 CFR 1926.451 requires fall protection for workers on scaffolds when working at heights of 10 feet or more above a lower level. This is a critical safety standard that contractors must enforce on job sites.
Why This Is the Correct Answer
OSHA 29 CFR 1926.451 specifically mandates that fall protection systems must be provided for employees working on scaffolds when they are 10 feet or more above a lower level. This regulation is part of the comprehensive scaffold safety standards that apply to all construction sites. The 10-foot threshold is a critical safety benchmark that contractors must strictly enforce to prevent serious injuries and fatalities from falls. This standard applies regardless of the type of scaffold being used, whether it's supported scaffolds, suspended scaffolds, or other scaffold systems.
Why the Other Options Are Wrong
Option C: 8 feet
6 feet is the fall protection threshold for other construction activities under OSHA 1926.501, but scaffolds have their own specific requirement of 10 feet under 1926.451.
Option D: 12 feet
12 feet exceeds the required threshold, meaning workers would be exposed to unnecessary risk for an additional 2 feet of height before fall protection would be required.
Memory Technique
Think 'Perfect 10' - scaffolds require fall protection at the perfect height of 10 feet, which is higher than the general 6-foot rule because scaffolds are considered more stable platforms.
