Properly installed guards shall be used on what?

• A. Gears
• B. All of the above
• C. Belt drive and take up
• D. Revolving parts of machinery

Answer: (B)

Guarding moving parts to prevent contact is essential. Gears rotate and can grab clothing or skin; belt drives and their take-up devices create nip points where a person could be pulled in; and any other revolving parts of machinery pose similar entanglement or crush hazards. Properly installed guards provide a barrier that keeps workers safe from these points across all these areas. Because guarding is needed for gears, belt drive and take-up, and other revolving parts, the correct choice is that guards are required on all of the above. If a guard is damaged or missing, it should be repaired or replaced before the equipment is operated, and maintenance should involve de-energizing and following proper lockout procedures.
