OSHA 29 CFR 1910.95(e) requires employers to notify workers when noise monitoring indicates their exposures may equal or exceed the 85 dBA TWA action level. This notification requirement is separate from STS written notification and from general HCP training requirements — it is specifically about communicating monitoring results that trigger or affect HCP enrollment. According to CDC/NIOSH, approximately 22 million U.S. workers face hazardous noise annually, all of whose exposure determinations must be communicated under these requirements.
What OSHA 1910.95(e) Actually Requires
Section 1910.95(e) establishes two employee notification obligations:
- Monitoring results notification: When monitoring indicates a worker may be exposed at or above the action level, the employer must notify the worker. This notification can occur through workplace posting, direct communication, or other effective means.
- Records access: 29 CFR 1910.1020 requires employers to provide workers access to their noise exposure monitoring records within 15 days of request. Workers must also be informed of the availability of these records.
The notification obligation is not one-time. When subsequent noise monitoring shows that exposure has changed — either increasing above the action level (requiring new HCP enrollment) or decreasing below it (potentially allowing removal from HCP) — affected workers must be notified. If process changes, equipment additions, or engineering controls alter noise levels in work areas, re-monitoring and re-notification are required to maintain compliance.
Documentation of Noise Monitoring Notifications
OSHA does not specify the exact format of noise monitoring notifications, but best practice requires documentation that can be produced during an inspection. Effective approaches include:
- Written letter or notice to each worker whose exposure meets or exceeds the action level, with copy retained in HCP file
- Posted notice in work areas with monitoring results by job classification, with posting date documented
- HCP enrollment paperwork that includes monitoring results and acknowledgment signature
The noise monitoring notification should be connected to the HCP enrollment process: when a worker is notified that their exposure exceeds the action level, the enrollment in the HCP (including scheduling of baseline audiogram) should happen as part of the same process. This creates a clear audit trail showing that the employer acted on monitoring results to enroll the worker within the required timeframe.
