Why is isolating the HVAC system important when salvage operations begin?

• A. To prevent cross-contamination to other spaces.
• B. To increase energy consumption.
• C. To reduce noise from equipment.
• D. To accelerate drying of water leaks.

Answer: (D)

Isolating the HVAC system creates a contained, controlled environment around the salvage area. When salvage begins, you want to limit the movement of moisture, contaminants, and odors to the rest of the building. An active HVAC system can circulate humid air and debris, spreading damage and making cleanup harder. By isolating, you prevent that air from moving into other spaces and you can precisely manage humidity with dehumidifiers and drying equipment in the affected zone. This containment helps moisture be drawn out more efficiently, increasing the rate at which water leaks dry. It also reduces the chance of recontamination as you work.
