Hearing conservation program Wikipedia. Hearing conservation programs are designed to prevent hearing loss due to noise and other environmental factors in different segments of society. Regarding occupational exposures to noise, a written hearing conservation program is required by the Occupational Safety and Health Administration OSHA whenever employee noise exposures equal or exceed an 8 hour time weighted average sound level TWA of 8. A scale slow response or, equivalently, a dose of fifty percent. This 8 hour time weighted average is known as an exposure action value. While the Mine Safety and Health Administration MSHA also requires a hearing conservation program, MSHA does not require a written hearing conservation program. MSHAs hearing conservation program requirement can be found in 3. CFR 6. 2. 1. 50,2 and requires has almost the same exact requirements as the OSHA hearing conservation program requirements. Therefore, only the OSHA standard 2. CFR 1. 91. 0. 9. 5 will be discussed in detail. Pdf Silent Printing Browser. Program requirementseditThe OSHA standard contains a series of program requirements.

CFR 1. 91. 0. 9. 5m states that employers shall maintain an accurate record of all employee exposure measurements. Sound surveyeditA sound survey is often completed to determine areas of potential high noise exposure. This type of survey is normally completed using a sound level meter SLM.

Maybe Ive spent too much time at Instructables World Headquarters, but I woke up this morning with a sudden urge to make myself a pocket protector. Upon seeing. There are three types of sound level meters. Type 0 is precision instrument normally used in laboratories. A type 1 is for precision measurements taken in the field. Type 2 sound level meters are less precise than type 1 and are often used to take all purpose sound level measurements. Noise monitoring is generally completed using a noise dosimeter that integrates all continuous, intermittent and impulsive sound levels3 to determine a persons noise exposure level. Surveys must be repeated when there are significant changes in machinery andor processes that would affect the noise level. Engineering and administrative controlseditEngineering controls and administrative controls are the preferred method to prevent noise exposure. Normally, they do not require personal protective equipment and therefore are normally more protective. However, it is not always feasible to use administrative and engineering controls as the only ways to prevent noise over exposure. The key is to maintain an 8 hour time weighted average of less than 8. BA so that personal protective equipment is not required. On October 1. 9, 2. US Department of Labour proposed that the term feasible be interpreted as that which is capable of being done, thus enhancing OSHAs ability to enforce this aspect of the standard. Hearing protection deviceeditIf engineering controls fail to maintain an 8 hour time weighted average below 8. BA, then a hearing protection device HPD is required. There are two general types of HPDs earplugs and earmuffs. Each one has its own benefits and drawbacks. The selection of the proper HPD to be worn is commonly done by an industrial hygienist so that the proper amount of noise protection is worn. OSHA requires that HPD be given free of charge. EarplugseditThere are four general classes of earplugs. These include premolded, formable, custom molded and semi insert. Premolded earplugs do not require the plug to be formed before it is inserted into the ear. This prevents the plugs from becoming soiled before insertion. Formable earplugs are made of a variety of substances. However, all each substance shares the common feature of being able to be shaped by the user prior to insertion. One drawback of this is the obvious need for the user to have clean hands while shaping the earplug. They do have the advantage of forming to the users ear, while many premolded earplugs do not accomplish this very well. Custom molded ear plugs are unique for each person, since they are cast from each users own ear canals. Therefore, they provide a personalized fit for each individual. Semi inserts are generally a soft earplug on the end of band. The band aides in maintaining the earplug in position. They are often useful since they can be quickly removed and inserted. EarmuffseditEarmuffs are another type of HPD. The main difference between earmuffs and earplugs, is that earmuffs are not inserted inside the ear canal. Instead the muffs create a seal around the outside of the ear to prevent noise from reaching the inner ear. Earmuffs are easy to wear and often provide a more consistent fit than an earplug. There are earmuffs available that use the principle of active noise control to help reduce noise exposures. However, the protection earmuffs offer may be mitigated by large sideburns or glasses as the seal of the earmuffs may be broken by these objects. Noise reduction ratingseditThe United States Environmental Protection Agency EPA requires that all hearing protection devices be labeled with their associated noise reduction rating NRR. The NRR provides the estimated attenuation of the hearing protection device. However, it has been found that the labeled manufacturers noise reduction ratings NRRs substantially overestimated the actual field attenuation performance. To determine the amount of noise reduction afforded by a hearing protection device, OSHA recommends that 7 db be subtracted from the NRR. The NRR is generally given in a C weighted format, so to obtain the A weighted reduction, one must subtract 7 db. OSHA also recommends a 5. OSHA recommended reduction would be NRR 72. Fit Testing for Hearing Protection. The NRR now has some help. Fit testing devices on the market that will verify a proper fit of an HPD hearing protection device. The fit of a hearing protector is very important, because if the HPD is not worn properly, the NRR becomes irrelevant. Products that will verify proper fit include 3. M EARFit Validation System, Fit.

Fit test systems provide a Personal Attenuation Rating PAR that is currently dependent upon the company that manufactures the fit testing system. Most fit test systems provide an A weighted PAR, which means that the attenuation can be subtracted from the A weighted noise exposure assessment of the employee or hearing protector user. System.
