CSLB C-33 Painting & DecoratingSafetyMedium

A painting contractor is supervising a crew working near an open trench on a commercial job site. OSHA requires fall protection for workers at specific heights. What is the minimum height threshold for requiring fall protection for workers working adjacent to a trench on a construction site?

  1. A15 feet
  2. B10 feet
  3. C6 feet
  4. D4 feet
Show answer & explanation

Correct answer: C. 6 feet

OSHA's general industry standard for fall protection is 4 feet, but for construction activities, including working near unprotected sides or edges of trenches, the threshold is 6 feet. This applies to falls into the trench, not just from elevated surfaces.

Why the other options are wrong

  • A. 15 feet is the threshold for certain types of aerial lifts or specific scaffold situations, not general trench work.
  • B. 10 feet is the threshold for some specific scaffolding types, but not for general construction fall protection near trenches.
  • D. 4 feet is the general industry standard, but construction requires 6 feet.

Construction Fall Protection Height

The minimum height above a lower level at which OSHA regulations mandate the use of fall protection systems for construction workers.

  • Generally 6 feet for construction activities.
  • Applies to unprotected sides, edges, and openings.
  • Different thresholds exist for specific tasks/equipment.

Memory trick: Six feet deep, your safety to keep.
