A roofing crew is utilizing a safety monitoring system as a fall protection method on a low-slope roof (less than 4:12 pitch) where the work is intermittent and short-duration. According to Cal/OSHA, what is the maximum allowable distance a worker can be from the safety monitor?

  1. A50 feet
  2. B30 feet
  3. C25 feet
  4. D75 feet
Show answer & explanation

Correct answer: C. 25 feet

Cal/OSHA regulations (Title 8, Section 1671.2(c)(7)(C)) specify that on low-slope roofs where a safety monitoring system is permitted, no worker shall be more than 25 feet from the safety monitor.

Why the other options are wrong

  • A. 50 feet is incorrect for safety monitoring system worker proximity; it often relates to warning line systems in some contexts, but not worker-to-monitor distance.
  • B. This distance is incorrect according to Cal/OSHA regulations for safety monitoring systems.
  • D. 75 feet is well beyond the allowable distance for a worker from a safety monitor under Cal/OSHA rules.

Cal/OSHA Safety Monitor Distance

When using a safety monitoring system for fall protection on low-slope roofs, workers must remain within 25 feet of the safety monitor.

  • Applies to low-slope roofs (4:12 pitch or less).
  • Monitor must have unobstructed view and be able to warn workers.
  • Maximum distance ensures timely intervention in case of fall hazard.

Memory trick: The monitor's keen eye, within 25 feet, keeps danger at bay.
