Essential Resources for Workplace Safety & Occupational Exposure Limits

Ensuring a safe workplace is paramount, and understanding occupational exposure limits (OELs) plays a crucial role in this endeavor. These limits define the maximum allowable concentration of hazardous substances in a worker’s breathing zone, encompassing forms such as gases, vapors, particles, aerosols, or fibers. Adhering to these limits helps prevent adverse health effects, providing clarity and safety for both employees and employers.

However, navigating the myriad of resources to find accurate and comprehensive information on OELs can be time-consuming and challenging. This is where DOHSBase becomes indispensable.
