Which of the following is NOT a primary function of proper ventilation in a workspace?

• A. Controlling sound levels
• B. Supplying fresh air
• C. Removing contaminants
• D. Controlling humidity

Answer: (D)

Ventilation’s main job is to exchange the air in a space: bring in fresh outdoor air and exhaust stale or contaminated indoor air. This dilution and removal of airborne hazards keeps people safer and helps maintain good air quality. Humidity, while it can be influenced by how much air is moving, isn’t the primary purpose of ventilation. Controlling moisture levels typically falls under dedicated climate-control equipment like humidifiers and dehumidifiers or a broader HVAC system designed for moisture management. So, while ventilation can affect humidity, it isn’t its core function, making humidity control the not-primary option in this context.
