What this covers

Sample questions

OSHA allows a safety monitoring system to be used alone, with no other fall protection, for roofing work on a low-slope roof that is no more than:

  1. 25 ft wide
  2. 100 ft wide
  3. 50 ft above the ground
  4. 50 ft wide
Show the answer

D. 50 ft wide

On low-slope roofs 50 ft or less in width a safety monitoring system by itself is permitted. Wider roofs need a warning line combined with the monitor, or guardrails, nets or personal fall arrest.

Reference: OSHA 29 CFR 1926.501(b)(10)

When no mechanical equipment is being used, a warning line on a low-slope roof must be set up at least how far from the roof edge?

  1. 3 ft
  2. 10 ft
  3. 6 ft
  4. 15 ft
Show the answer

C. 6 ft

The line goes around all sides of the work area no closer than 6 ft to the edge. The 10 ft distance applies at the edge that is perpendicular to the direction mechanical equipment is traveling.

Reference: OSHA 29 CFR 1926.502(f)(1)

A warning line must be rigged so that it stays within what height range above the roof surface?

  1. 24 to 30 in.
  2. 34 to 39 in.
  3. 39 to 45 in.
  4. 42 to 48 in.
Show the answer

B. 34 to 39 in.

The lowest point, including sag, may not be under 34 in. and the highest point may not be over 39 in. The 39 to 45 in. range is for a guardrail top rail, a different system.

Reference: OSHA 29 CFR 1926.502(f)(2)(ii)
