What is the primary purpose of an OEL?

• A. To calibrate equipment
• B. To protect personnel from hazardous OEH threat exposures
• C. To determine salaries
• D. A guideline for building safety

Answer: (B)

The main idea behind an occupational exposure limit is to protect workers by defining a safe maximum concentration of a hazardous substance in workplace air. It provides a measurable standard for monitoring air, guiding actions to reduce exposure, and confirming that controls (like ventilation, process changes, or PPE) keep exposure within a healthy range. It’s not about calibrating equipment, salaries, or building safety guidelines.
