Which statement about the ventilation standard is true?

Which statement about the ventilation standard is true?

• A. Wipe down surfaces with condensation at least twice hourly
• B. Set refrigeration units to keep temperature and humidity at or below specified levels
• C. Provide 10 fans per 1,000 square feet of floor space
• D. Adequately control odors, vapors, and condensation

Answer: (D)

Ventilation standards focus on maintaining air quality and controlling moisture by removing odors, vapors, and excess humidity from the space. The best statement captures this purpose by emphasizing adequately controlling odors, vapors, and condensation through proper ventilation design and operation. Wiping condensation is a cleaning action, not the ventilation standard itself. Setting temperature and humidity targets relates to environmental controls, not how the ventilation system handles air contaminants. A fixed ratio of fans per area is a prescriptive guideline, not the fundamental concept of ventilation standards. Controlling odors, vapors, and condensation directly reflects the goal of ventilation to keep the space ventilated and the air safe and comfortable.
