Guarding is required on which parts of machinery?

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

Answer: (D)

Guarding is needed on all exposed moving parts of machinery because anything that moves can injure a worker if touched, snagged, or pulled in. Gears have teeth that can grab fingers or clothing, so they must be enclosed to prevent contact. Belt drives and their take-ups present a risk of clothing or hair being drawn in or pinched, making guarding essential. Revolving parts like shafts, couplings, and pulleys can entangle or sever if a body part or clothing comes near them, so they also require protection. Because each of these areas creates a different kind of hazard, guarding all of them helps prevent injuries, which is why the best choice is that guarding is required on all of the above.
