According to OSHA, what is the minimum width required for scaffold platforms?
Correct Answer
C) 18 inches
OSHA requires scaffold platforms to be at least 18 inches wide. This provides adequate working space for employees while maintaining safety on elevated work surfaces.
Why This Is the Correct Answer
OSHA Standard 29 CFR 1926.451(f)(1) specifically requires scaffold platforms to have a minimum width of 18 inches. This width provides sufficient space for workers to perform their tasks safely while maintaining proper balance and allowing room for tools and materials. The 18-inch minimum ensures workers have adequate footing and reduces the risk of falls from narrow platforms. This requirement applies to all types of scaffolds including supported scaffolds, suspended scaffolds, and other scaffold systems.
Why the Other Options Are Wrong
Option B: 16 inches
16 inches is too narrow and does not meet OSHA's minimum safety requirements for scaffold platforms, which could create unsafe working conditions.
Option D: 20 inches
20 inches exceeds the minimum requirement, and while wider platforms are acceptable, this is not the minimum width specified by OSHA regulations.
Memory Technique
Use the mnemonic '18 and SAFE' - the minimum platform width is 18 inches to keep workers SAFE on scaffolds.
