Under OSHA 29 CFR 1926, what is the minimum width required for scaffolding platforms?
Correct Answer
A) 18 inches
OSHA 29 CFR 1926.451 requires scaffolding platforms to be at least 18 inches wide. This minimum width provides adequate working space and helps prevent falls from scaffolds.
Why This Is the Correct Answer
OSHA 29 CFR 1926.451(b)(2)(i) specifically mandates that scaffold platforms must be at least 18 inches wide. This regulation is designed to provide sufficient working space for construction workers while maintaining safety standards. The 18-inch minimum ensures workers have adequate room to perform tasks without being forced to work too close to the platform edge. This width requirement is a fundamental safety standard that applies to most scaffold platforms used in construction.
Why the Other Options Are Wrong
Option C: 20 inches
16 inches is below the OSHA minimum requirement and would not provide adequate working space for safe scaffold operations.
Option D: 24 inches
24 inches is well above the minimum requirement and would be unnecessarily wide for the regulatory minimum standard.
Memory Technique
Think '18 and safe' - the minimum 18 inches keeps workers safe on scaffold platforms, or remember that 18 is the legal voting age, and 18 inches is the legal minimum platform width.
