NIOSH Power Tools Database
The NIOSH Power Tools Database contains sound power levels, sound pressure levels, and vibrations data for a variety of common power tools that have been tested by researchers. Data are collected for both the unloaded and loaded use of power tools. The database was created by the National Institute for Occupational Safety and Health (NIOSH).
==Purpose==
This (database ) was created in order to provide information to the general public about the sound and vibrations generated by power tools during their use. Many of these tools produce sound levels high enough to damage hearing if precautions are not taken. Since this information was not readily available in most cases, NIOSH created the Power Tools Database and ran tests on power tools to provide the information. According to NIOSH, the Power Tools Database "is particularly helpful in determining the 'real-world' noise level of power tools as they are used on the job."〔(NIOSH Power Tools Database )〕〔(National Academies, Institute of Medicine, Hearing Loss Research at NIOSH: Reviews of Research Programs of the National Institute for Occupational Safety and Health, Chapter 2 page 59 (National Academies Press, Washington DC) )〕 The database is a part of the much larger Hearing Loss Prevention Research Program conducted by NIOSH. The Hearing Loss Prevention Research Program is designed to reduce occupational hearing loss through research and the application of the research to real-world situations.〔(NIOSH Hearing Loss Prevention Program Description )〕 This database advances this goal by informing buyers and users of power tools of the dangerous levels of noise and vibrations that they are exposed to while using the tools. By making people aware of how loud power tools actually are, NIOSH is attempting to encourage the design and production of quieter power tools and the proper use of hearing protectors when using such tools. The database is also part of a larger NIOSH prevention initiative called Buy Quiet. In recent years, Buy Quiet programs and initiatives have arisen in an effort to combat occupational noise exposures. These programs promote the purchase of quieter tools and equipment.〔http://www.cdc.gov/niosh/topics/buyquiet/default.html〕
Noise-induced hearing loss (NIHL) is an increasingly common disorder often caused by work-related activities. Construction, manufacturing, and mining are some of the most susceptible occupations to NIHL, since many workers in these fields are exposed to high levels of noise on a daily basis.〔http://www.safetyandhealthmagazine.com/articles/9196-complacency-is-real〕 A substantial part of this noise results from the use of power tools, which can produce dangerous levels of noise by themselves.〔(Neitzel R, (2008) "How Bad is Construction Noise and What Can Be Done About It?" AudiologyOnline 9/22/2008 )〕 Although the loudness of power tools may be quite apparent to those using them, the actual level of noise produced was mostly unreported and not available easily in an online reference. This database provides detailed information about these noise levels so that appropriate action may be taken to protect workers from them.
