The Code of Federal Regulations (CFR) Part 1910.95 Occupational Noise Exposure requirements adopted by The U.S. Department of Labor Occupational Safety and Health Administration (OSHA) requires employers to protect employees from prolonged exposure to noise. The current requirements developed by OSHA as set forth in this standard limit time weighted average (TWA) employee noise exposure to not greater than 90 dBA per 8-hour time duration, or a typical work day. In addition, a hearing conservation program is required if employee TWA noise exposure exceeds 85 dBA, or the “action level”, over the work day. A hearing conservation program includes annual audiometric testing for employees working in noise hazardous areas, educating employees on the effects of prolonged noise exposure and hearing loss, providing custom and selectable hearing protection devices and feasible noise mitigation in noise hazardous areas. BWS assists industrial clients with developing short-term and long-term industrial noise abatement programs.
GE Turbines Test Stand 8 Control Room
A general program may incorporate the following:
- Facility noise survey and mapping
- Identification of noise hazardous areas and equipment producing excessive noise
- Comprehensive Time Weighted Average employee noise exposure monitoring
- Noise abatement design analysis and noise mitigation techniques
- Facility assessment detailing short-term and long-term goals for achieving OSHA compliance
We also assist our clients with cost evaluation of recommended noise abatement options and specialty systems. We work with product vendors and subcontractors to ensure our designs are properly implemented from inception to completion. Our extensive knowledge and application of industrial noise control measures eliminates any miscommunication between industry, subcontractors and vendors.
Project Profile: Equifax Data Center, Alpharetta, Georgia
Being one of the “Big 3” credit reporting agencies, the Equifax Data Center must always remain “online”. A power outage lasting even a few seconds can cost millions of dollars and credibility. The data center’s backup power system produces noise exceeding 110 dBA. BWS provided a custom design to protect employees which also required compliance with Alpharetta’s strict noise policy. Since the property line is less than 30’ from the building, this proved challenging.
