What is the primary purpose of a baseline survey for ventilation systems?

• A. Establish baseline operation and hazard survey
• B. Determine replacement cost
• C. Train staff
• D. Schedule maintenance

Answer: (A)

The main concept being tested is establishing a reference point by capturing how the ventilation system is operating now and what hazards exist. A baseline survey inventories current airflow, ventilation rates, filtration performance, control settings, energy use, and potential hazards or exposure risks. This snapshot provides a foundation to compare future performance after changes, upgrades, or different occupancy, helping verify that the system meets design intent and that controls effectively manage risks. It isn’t primarily about how much it would cost to replace equipment, nor about training staff, nor about scheduling maintenance—those are separate activities that follow from the baseline information.
