Without a roof guard, the rooftop condenser must be set back from the edge by at least how many feet?

• A. 6 feet
• B. 8 feet
• C. 10 feet
• D. 12 feet

Answer: (C)

Setting rooftop equipment back from the edge is a safety measure to provide a fall-protection buffer and safe access for servicing. Without a roof guard, the condenser must be positioned at least ten feet away from the edge to reduce the risk of falls and to allow room for safe maintenance around the unit. Six or eight feet don’t give enough clearance for someone working near the edge, while twelve feet is more than the minimum required. Ten feet strikes the appropriate balance between safety and practical placement on most rooftops.
