Chapter 6640 Hearing Conservation Program

High noise is a recognized hazard issue at Jefferson Lab. This hearing conservation program has been established to ensure affected areas are identified, appropriate monitoring is established, and individuals are informed of the dangers and adequately protected.

This program satisfies applicable federal, state, and local requirements as outlined in ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List.

This program applies to continuous or intermittent noise at or above 85 dBA or greater.

Medical Certification for High Noise
* Per ES&H Manual Chapter 6800 Appendix T1 Medical Monitoring


T1 High Noise Exposure Assessment
A high noise exposure assessment and subsequent monitoring is conducted when individual exposure or work area noise levels are suspected to be 85 dBA or above. ES&H Manual Chapter 6640 Appendix T1 High Noise Exposure Assessment provides recognized high noise symptoms, the process steps used to schedule and obtain an exposure assessment, and how area monitoring is implemented.
T2 High Noise Hazard Controls
Hearing protection is required at Jefferson Lab when high noise levels have been determine to be 85 dBA or greater. ES&H Manual Chapter 6640 Appendix T2 High Noise Hazard Controls provides the process step used to determine the appropriate type and when to obtain medical monitoring and training.
T3 High Noise Posting Requirements
Jefferson Lab recognizes that high noise is inherently dangerous. It is therefore required that designated areas be posted to provide warning of the potential hazard. ES&H Manual Chapter 6640 Appendix T3 High Noise Posting Requirements defines Jefferson Lab's labeling and posting requirements; and how to update, repair, and maintain these labels.

Management authority may be delegated to a task qualified Jefferson Lab employee at the discretion of the responsible manager.
