What does the term "exposure limit" refer to?

The term "exposure limit" specifically refers to the maximum concentration of a substance that workers can be exposed to in their workplace over a designated time period, such as an 8-hour shift or a 40-hour workweek. This limit is established to protect workers from the adverse health effects of hazardous substances, including chemicals and physical agents, promoting workplace safety and ensuring that exposure levels remain within safe thresholds.

These limits are often set by regulatory agencies based on scientific research and are crucial in creating safe workplace environments. They are designed to prevent acute and chronic health issues that can arise from prolonged or excessive exposure. By adhering to exposure limits, employers can establish effective safety protocols and implement necessary controls to reduce risks associated with hazardous substances.
