What is the main purpose of establishing exposure limits like PEL and REL?

Establishing exposure limits such as Permissible Exposure Limits (PEL) and Recommended Exposure Limits (REL) is primarily aimed at ensuring worker safety. These limits are guidelines developed to protect workers from the harmful effects of exposure to hazardous substances in the workplace. By defining safe levels of exposure, these limits help mitigate the risk of illness, injury, and long-term health effects resulting from occupational hazards.

Worker safety is the fundamental concern behind setting these standards; they are based on scientific research and data that indicate the maximum concentration of a substance to which a worker can be exposed without experiencing adverse health effects. Therefore, organizations utilize these limits to create safe working environments and to adhere to health regulations, ultimately preserving the well-being of employees engaged in potentially dangerous occupations.

In this context, while options like maximizing productivity, reducing costs, or simplifying compliance may be secondary considerations, they do not reflect the primary goal of establishing these exposure limits, which is centered around protecting the health and safety of workers.
