For belt-driven machinery with belts seven feet or less from the floor, guards must be how many inches above the belt?

• A. 15 inches
• B. 10 inches
• C. 20 inches
• D. 8 inches

Answer: (A)

Guarding belt-driven machinery is all about preventing contact with moving belts and pulleys. When the belt is close to the floor, the guard must create a substantial barrier so hands, clothing, or tools can’t reach into the moving belt area. For belts seven feet or less from the floor, extending the guard so it sits fifteen inches above the belt provides a protective gap large enough to deter reach-ins while still allowing safe operation and maintenance. Shorter gaps leave a greater opportunity for a hand or object to access the belt, while a much taller guard isn’t typically needed and can complicate maintenance. That’s why fifteen inches above the belt is the required height in this situation.
