Once engineering controls are installed, they need to be maintained — or they stop protecting anyone.
Why It Matters:
Noise-reduction solutions like barriers, enclosures, and vibration dampeners wear out over time. If not properly maintained, they can become ineffective — or worse, make noise problems even worse. Regular upkeep ensures these controls continue reducing hazardous noise and protecting everyone in the area.
Key Points:
- Check enclosures and barriers regularly for damage, gaps, or missing panels. A cracked sound booth is no longer effective.
- Inspect vibration dampeners and isolators to make sure they haven’t hardened, cracked, or slipped out of place.
- Clean and maintain equipment to prevent rattling or grinding noises caused by debris, loose parts, or poor lubrication.
- If noise seems to be increasing, treat it as a red flag — something may be wearing out or failing.
- Upgrades may be required over time as equipment ages or new, quieter alternatives become available.
- Coordinate with safety and maintenance teams to schedule inspections of noise control systems.
- Document all issues and repairs as part of your hearing conservation program.
✅ Noise control is not “set it and forget it.”
Ask the Crew:
- When was the last time we inspected our noise barriers or sound enclosures?
- Are any machines louder than they used to be?
- Do we have a system for reporting deteriorating noise control measures?
