Why are recommended exposure limits (RELs) important for workers?

Recommended exposure limits (RELs) are essential for safeguarding worker health because they are scientifically determined thresholds that indicate the maximum amount of a hazardous substance that workers can be exposed to over a specific time period without experiencing adverse health effects. These limits are formulated based on research and evaluations of how various substances can impact human health, considering factors such as toxicity, potential routes of exposure, and the duration of exposure.

By adhering to RELs, employers can create a safer work environment that minimizes the risk of illnesses or injuries associated with hazardous substances. Ensuring that exposure levels remain below these established limits is a critical aspect of occupational health and safety regulations, as it directly aids in preventing long-term health issues and acute exposure effects among workers. Hence, the application of RELs contributes directly to maintaining employee safety and well-being in workplaces where hazardous substances are present.
