According to OSHA standards, what is the minimum width requirement for scaffolding platforms?
Correct Answer
B) 18 inches
OSHA 29 CFR 1926 requires scaffold platforms to be at least 18 inches wide. This minimum width ensures adequate working space and safety for workers on scaffolds.
Why This Is the Correct Answer
OSHA 29 CFR 1926.451(b)(1) specifically mandates that scaffold platforms must be at least 18 inches wide to provide adequate working space for construction workers. This width requirement ensures workers have sufficient room to perform their tasks safely while maintaining proper balance and stability. The 18-inch minimum also allows for safe movement of materials and tools on the platform without creating hazardous conditions.
Why the Other Options Are Wrong
Option C: 20 inches
20 inches exceeds the minimum requirement, and while acceptable, it is not the minimum standard specified by OSHA.
Option D: 24 inches
24 inches exceeds the minimum requirement, and while acceptable for use, it is not the minimum standard specified by OSHA regulations.
Memory Technique
Think '18 and safe' - the minimum 18 inches keeps workers safe on scaffold platforms.
