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?
