Identifying High-Noise Tasks

Toolbox Talk:

Rotating Workers Out of High-Noise Zones

June 27, 2025

Long-term noise exposure isn’t just about how loud it is — it’s about how long you’re exposed. Rotating workers in and out of high-noise areas can reduce risk and protect hearing over time.

Why It Matters:

Even with hearing protection, extended exposure to noise above 85 dB can cause cumulative damage. By rotating crews, you lower individual exposure and give ears time to recover.

Key Points:

  • High-noise areas include jackhammer zones, demo areas, and generator banks.
  • OSHA bases exposure limits on both decibel level and duration — louder zones allow less time.
  • Plan tasks to minimize continuous exposure:
    • Break up shifts near loud equipment.
    • Assign alternating duties (e.g., 2 hours on, 2 hours off).
  • Use break areas in quieter spots to reduce total daily exposure.
  • Supervisors should monitor time-in-zone for all workers and adjust schedules accordingly.
  • Track who’s exposed and for how long — don’t rely on guesswork.

✅ Swapping tasks can save someone’s hearing.

Ask the Crew:

  • Are any of us spending too long near loud equipment today?
  • Can we rotate or take breaks to reduce noise exposure?
