OSHA's PEL for noise exposure is 90 decibels (dBA) for an 8-hour TWA. Levels of 90-140 dBA are included in the noise dose. [4] PEL can also be expressed as 100 percent “dose” for noise exposure. When the noise exposure increases by 5 dB, the exposure time is cut in half. [5] According to OSHA, a 95dBA TWA would be a 200 percent dose. [6]
An Exposure Action Value (EAV) or Action Value (AV) is a limit set on occupational exposure to noise where, when those values are exceeded, employers must take steps to monitor the exposure levels. These levels are measured in decibels. The American Occupational Safety and Health Administration (OSHA) set the EAV to 85 dB
Relationship between noise exposure levels and duration of allowable exposure at that level for NIOSH and OSHA Time to reach 100% noise dose Exposure level per NIOSH REL Exposure level per OSHA PEL 8 hours 85 dBA 90 dBA 4 hours 88 dBA 95 dBA 2 hours 91 dBA: 100 dBA 1 hours 94 dBA: 105 dBA 30 minutes 97 dBA: 110 dBA 15 minutes
This relationship between allotted noise level and exposure time is known as an exposure action value (EAV) or permissible exposure limit (PEL). The EAV or PEL can be seen as equations which manipulate the allotted exposure time according to the intensity of the industrial noise. This equation works as an inverse, exponential, relationship.
Threshold limit value − time-weighted average (TLV-TWA): The average exposure on the basis of a 8 hours per day, 40 hours per week work schedule. Threshold limit value − short-term exposure limit (TLV-STEL): A 15-minute TWA exposure that should not be exceeded at any time during a workday, even if the 8-hour TWA is within the TLV-TWA.
The EU specifies several different exposure action values: a "lower" value of 80 dBA at which the employer must make hearing protection devices available to the employee; an "upper" value of 85 dBA at which the employee is required to wear hearing protection; and an "exposure limit" value of 87 dBA, under which the individual's noise exposure ...
An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by competent national authorities and enforced by legislation to protect occupational safety and health .
Furthermore, OSHA has set permissible exposure limits [9] (PEL) on around 500 chemicals which are enforceable by law. These exposure limits include evidence that a certain amount of a chemical exposure is linked to one or more adverse health effects.
