What is the minimum distance from the edge for a roof-mounted refrigeration condenser without a roof guard?

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

Answer: (C)

Creating a safe working buffer from the roof edge is the main idea here. When a roof-mounted refrigeration condenser sits without a protective roof guard, you want enough space so technicians can access, open panels, and maneuver around the unit without risking a fall or being too close to the edge. Ten feet provides a generous margin that helps prevent accidental slips toward the edge and gives room for service tasks, hoses, and connections to be handled safely. If a guard rail or parapet is present, the required setback is typically reduced because the guard provides protection, but without any guard, the ten-foot distance is the practical safety standard.
