What is the process of maintaining fresh air in a building called?

• A. Ventilation
• B. Bloodborne Pathogen Disinfection
• C. Disinfectants
• D. Occupational Safety and Health Administration

Answer: (A)

Ventilation is the process of exchanging indoor air with outdoor air to maintain fresh air inside a building. It helps dilute and remove contaminants, control humidity, and keep oxygen levels sufficient for occupants. This can happen naturally, through openings like windows and vents, or mechanically, with fans and ventilation systems that bring in outside air and exhaust indoor air. The other terms relate to cleaning or safety regulation rather than moving air: disinfectants are chemicals used to kill pathogens on surfaces, bloodborne pathogen disinfection refers to surface decontamination of disease-causing organisms, and the Occupational Safety and Health Administration is the agency that enforces safety standards, not the air-exchange process.
