• A. 12
• B. 10
• C. 6
• D. 15

Answer: (B)

The rule is about protecting workers from falls when they have to service equipment located near the roof edge. If appliances or other components that require service are close enough to the edge, a guard must be in place to create a barrier between the worker and the edge while servicing, opening panels, or performing adjustments. This distance is chosen to provide a reliable safeguard in typical rooftop maintenance scenarios, reducing the chance of slipping or stepping off the edge during work. When the equipment is farther from the edge than this threshold, that specific guard requirement doesn’t apply, though other fall-protection measures may still be relevant. The other distances would either impose guards too often or risk leaving workers un protected in a situations where the guard is needed, so the stated threshold best supports safety during service.
