What is the purpose of monitoring air quality in work areas?

• A. To monitor sunlight exposure.
• B. To reduce electricity bills.
• C. To ensure a safe working environment.
• D. To measure noise levels.

Answer: (C)

Monitoring air quality in work areas is about protecting workers from airborne hazards by keeping track of contaminants such as dust, fumes, vapors, gases, and biological agents. When measurements show levels that could harm health, ventilation, containment, or filtration can be adjusted and appropriate PPE used to bring exposure back within safe limits. This direct action helps prevent respiratory irritation, acute illness, and long-term health problems, and it supports compliance with occupational exposure standards. Other goals like sunlight exposure, electricity costs, or noise levels address different safety or operational concerns and do not focus on the health risks posed by airborne contaminants.
