Which action best reduces exposure to vibrations and noise on a worksite?

• A. Use PPE, maintain equipment, minimize exposure per policy, and implement engineering controls where possible.
• B. Ignore maintenance and wear earplugs only.
• C. Increase equipment speed to test limits.
• D. Work without hearing protection if in a hurry.

Answer: (A)

Reducing exposure to vibrations and noise on a worksite comes from using a layered approach that targets both the source and the worker. Address the equipment itself to lower the amount of vibration and noise it emits, keep up with maintenance so worn parts don’t amplify noise or vibration, and limit how long workers are exposed to noisy or vibrating conditions according to policy. When possible, add engineering controls such as noise enclosures, vibration dampers, or isolation mounts to further cut the levels at the source. On top of all that, use hearing protection and other PPE to provide a final safeguard for any remaining exposure. This combination is more effective than relying on a single measure, because it tackles both the cause and the exposure.

Relying only on PPE misses the chance to reduce the noise and vibration at the source, ignoring maintenance lets the problem worsen, and increasing equipment speed or skipping protection altogether would raise exposure rather than reduce it.
