The guard must extend at least ____ inches above the belt where both runs or horizontal belts are 7 feet or less from the floor or working surface.

• A. 10 Inches
• B. 15 Inches
• C. 12 Inches
• D. 20 Inches

Answer: (B)

Guarding belt conveyors protects workers from moving parts and potential material ejection. When the belt runs are close to the floor—within 7 feet—the guard must be tall enough to prevent a hand, arm, clothing, or other body part from reaching into the belt area. The required extension is 15 inches above the belt, providing sufficient clearance for typical reach and reducing the chance of contact with moving parts or pinch points. This is why 15 inches is the correct requirement for this situation.
