Simple representation of exposure risk assessment and management hierarchy based on available information Hierarchy of occupational exposure limits (OELs) Illustration of statistical output from IHSTAT using air sampling data. Personal air sampling is routinely conducted on workers to determine whether exposures are acceptable or unacceptable.
Occupational exposure banding has been used by the pharmaceutical sector and by some major chemical companies over the past several decades to establish exposure control limits or ranges for new or existing chemicals that do not have formal OELs. [2] Furthermore, occupational exposure banding has become an important component of the Hierarchy ...
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 ...
National Institute for Occupational Safety and Health (NIOSH) RELs are designed to protect the health and well-being of workers by recommending safe exposure levels. To really use these guidelines well, safety professionals need to understand the recommended exposure levels, how to measure them, and ways to make sure workers aren't exposed to harmful stuff.

The exposure assessment is initiated by selecting the appropriate exposure limit averaging time and "decision statistic" for the agent. Typically the statistic for deciding acceptable exposure is chosen to be the majority (90%, 95% or 99%) of all exposures to be below the selected occupational exposure limit.
The anticipate, recognize, evaluate, control, and confirm (ARECC) decision-making framework began as recognize, evaluate, and control.In 1994 then-president of the American Industrial Hygiene Association (AIHA) Harry Ettinger added the anticipate step to formally convey the duty and opportunity of the worker protection community to proactively apply its growing body of knowledge and experience ...
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.
