What is the noise level in an open cab excavator and should I be requiring hearing protection?
The best way to measure noise levels is through noise hazard evaluation and measuring an 8-hour time weighted average (TWA) for noise to ensure levels are below 85 decibels of noise. OSHA regulates noise at 85 and 90 decibels, according to 29 CFR 1910.95. 85 dB represents the point at which an employer must provide audiometric (hearing) testing and offer hearing protection to employees. Audiometric testing, hearing protection, a company written program, and training are required at 90 decibels. For more information on hearing conservation requirements, refer to 29 CFR 1910.95. The National Institute of Occupational Safety and Health (NIOSH) has published some examples of noise levels that would require hearing conservation programs. Here are some facts about the levels of noise. Are you protecting your workers hearing adequately?
