Which statement about OEL is true?

Which statement about OEL is true?

• A. It is a financial metric
• B. It is a limit designed to protect personnel from hazardous OEH threat exposures
• C. It applies only to environmental health outside the workplace
• D. It is a general safety guideline for all industries

Answer: (B)

Occupational exposure limits set the maximum allowable concentration of a hazardous substance in workplace air to protect workers over a specified period. They guide precautions and engineering controls to keep health risks at bay, typically expressed as ppm or mg/m3 and tied to time frames like an 8-hour work shift (and sometimes a short-term limit for brief exposures). This statement is the best fit because it captures that purpose: a limit designed to protect personnel from hazardous exposures in the workplace. It’s not a financial metric, not specifically about environmental health outside the workplace, and not a general safety guideline for all industries—the focus is on occupational exposure within the work environment.
