A measure of an acceptable limit of exposure for human beings as defined by the Occupational Safety and Health Administration (OSHA).
An exposure limit established and enforced by the Occupational Safety and Health Administration (OSHA) which may be expressed as a time-weighted average (TWA) limit, short term exposure limit (STEL) or ceiling exposure limit (C).
Maximum exposure to a given chemical recommended by the US Occupational Safety and Health Administration (OSHA) to protect worker health and safety.
(PEL) - An exposure limit that is published and enforced by OSHA as a legal standard. PEL may be either a time-weighted-average (TWA) exposure limit (8-hour), a 15-minute short-term exposure limit (STEL), or a ceiling (C). The PEL's are found in Tables Z-1, Z-2, or Z-3 or OSHA regulations 1910.1000. (See also TLV).
permissible exposure limits for the work place, set by regulation and enforced by OSHA. Most of these limit values were originally set, by consensus, by the ACGIH to assist industrial hygienists in implementing exposure control programs. As law, these are listed in 29 CFR 1910.1000 and subject to revision through the regulatory process.
the legal level of exposure to a substance that is allowed by OSHA.
PELs are established by the Department of Labor acting through OSHA (Occupational Safety and Health Administration). A PEL represents the maximum worker exposure allowed for a substance over an eighthour day. While both threshold limit values (TLVs) and PEL values have been established for many substances, they are not necessarily the same. The TLVs are examined and modified more frequently than the PEL values. Consequently, in most cases, the TLV represents a more recent evaluation of the hazards associated with worker exposure to a substance.
An exposure limit that is published and enforced by OSHA as a legal standard. PEL may be either a time-weighted-average (TWA) exposure limit (8 hour), a 15-minute short term exposure limit (STEL), or a ceiling (C). The PELs are found in Tables Z-1, Z-2, or Z-3 of 29 CFR 1910.100. This level of exposure is deemed to be the maximum safe concentration and is generally the same value as the threshold limit value (TLV).
90 dBA TWA. Employees may be exposed to 90 dBA for an 8 hour time weighted average (TWA) exposure without experiencing serious hearing effects.

An exposure limit that is published and enforced by the Occupational Safety and Health Administration as a legal standard. A permissible exposure limit may be either a time-weighted-average (TWA) exposure limit (8 hour), a 15-minute short-term exposure limit (STEL), or a ceiling limit (CL).
The allowable exposure that an employee can be exposed to over an 8-hour Time-Weighted Average (TWA). For formaldehyde, the limit is 0.75 parts per million (ppm).
OSHA's number that tells the concentration of a chemical in air that a worker may breathe for a given period of time without experiencing adverse effects.
The legally established time-weighted average (TWA) concentration or ceiling concentration of a contaminant that shall not be exceeded.
A list published by California Occupational Health and Safety Administration for exposure concentrations that a healthy individual normally can tolerate for 8 hours a day, five days a week, without harmful effects. Airborne particulate concentrations are listed as milligrams per cubic meter of air (mg/m3), and gaseous concentrations are listed as parts per million (ppm,) by volume.
An exposure limit that is published and enforced by OSHA as a legal standard. PEL may be either a time-weighted average (TWA) exposure limit (8 hour), or a 15 minute short term exposure limit (STEL) or a ceiling (C). The PEL's are found in Tables Z1, Z2 or Z3 of OSHA Regulation 1910.1000.
Recommendation by US OSHA for TWA concentration that must not be exceeded during any 8-hour work shift of a 40h working week. RT maximum allowable concentration, threshold limit value, time weighted average concentration (TWAC), exposure limit
The maximum time-weighted concentration at which 95% of exposed, healthy adults suffer no adverse effects over a 40-hour work week and are comparable to ACGIH's TLV/TWA. PELs are used by OSHA and are based on an eight-hour, time-weighted average concentration.
The Permissible Exposure Limit (PEL or OSHA PEL) is a legal limit in the United States for exposure of an employee to a substance, usually expressed in parts per million (ppm), or sometimes in milligrams per cubic metre (mg/m3). Permissible Exposure Limits are established by the Occupational Safety and Health Administration (OSHA).
