What is a definition of 'exposure limit'?

An 'exposure limit' refers specifically to the maximum allowable concentration of a hazardous substance in the workplace. This is important because it sets a regulatory standard meant to protect workers' health by dictating the highest level of exposure that is considered safe over a specified time period. Exposure limits are typically established based on scientific research and risk assessments that examine the health effects associated with various levels of exposure to specific chemicals or substances.

For instance, regulatory agencies like the Occupational Safety and Health Administration (OSHA) and the American Conference of Governmental and Industrial Hygienists (ACGIH) define these limits to help ensure that occupational environments are safe and that workers are not subjected to harmful levels of toxic substances. Understanding exposure limits is crucial for implementing safety measures, monitoring workplace conditions, and ensuring compliance with health regulations.
