What term indicates the difference in air pressure between negative air space and positive or equal air spaces?

• A. Waterborne
• B. Vector
• C. Air Pressure Differential
• D. Abatement

Answer: (C)

Air pressure differential is the difference in pressure between spaces, and it’s what controls the direction of airflow. In a negative air space, the pressure is lower than in adjacent spaces, so air tends to flow into that space rather than out. This containment helps prevent contaminated air from escaping to other areas. The magnitude of this difference is measured in units like inches of water or Pascals and is maintained to keep the airflow direction consistent, even when doors open. Waterborne, vector, and abatement describe transmission routes, carriers, and hazard reduction, respectively, not the pressure differences that govern containment.
