The permissible exposure limit (PEL or OSHA PEL) is a legal limit in the United States for exposure of an employee to a chemical substance or physical agent such as high level noise. Permissible exposure limits were established by the Occupational Safety and Health Administration (OSHA). Most of OSHA's PELs were issued shortly after adoption of ...
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 .
These exposure limits include evidence that a certain amount of a chemical exposure is linked to one or more adverse health effects. For instance, heart disease [10] is more prevalent in workers who are exposed to the chemicals found in engine exhausts. Exposure to carbon tetrachloride has shown to cause liver and kidney damage.

Each industry is different, as workers' tasks and equipment differ, but most regulations agree that noise becomes hazardous when it exceeds 85 decibels, for an 8-hour time exposure (typical work shift). This relationship between allotted noise level and exposure time is known as an exposure action value (EAV) or permissible exposure limit (PEL ...
This TWA is calculated for a standard workday of up to 10 hours, over a 40-hour workweek. This is slightly different to permissible exposure limit (PELs), which are calculated for 8 hours over a 40-hour workweek instead. [1] NIOSH recognizes that certain scenarios demand more immediate attention and has therefore introduced additional measures.
The agency issued final guidance that it estimated could reduce lead exposure from processed baby foods by about 20% to 30%. ... The FDA guidance sets a lead limit of 10 parts per billion for ...
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.
