Noise induced hearing loss (NIHL)
To demonstrate noise abatement technology effectiveness on treating the noise in the Hoover Dam power plant identified via the noise engineering control survey completed in July of 2016.
Need and Benefit
Engineering controls are the first line of defense against work place hazards. This project will allow the Hoover dam power plant to eliminate identified noise hazards and isolate them. In the Hoover Dam power plant all area on the noise engineering survey were identified ranging from 89 dBA- 106 dBA. The best way to protect employees is to install effect engineering controls. Effective engineering controls will help improve the environment and help reduce NIHL and hearing loss claims. This engineering controls will help prevent future hearing loss claims and will protect workers against recognized hazards. This demonstration will show effectiveness of engineering controls at a location with noise levels in the 90s in most locations of the facility. During this project Temp coat and Silent Running coating will be tested to see capability for it to be used on piping systems to reduce noise. The data collected by Reclamation doesn't show the capability of sound solutions working on areas. This demonstration will show abatement ability for high noise environments throughout Reclamation.
