What is an effective method to increase ventilation in affected areas after flooding?

Using exhaust fans and opening windows is an effective method to increase ventilation in areas affected by flooding because it enhances airflow, which is crucial for drying out moisture and reducing humidity levels. Proper ventilation allows for the exchange of stale, damp air with fresh air from outside, accelerating the evaporation process and helping to prevent the growth of mold and mildew, which thrive in wet environments.

Exhaust fans help to pull the moist air out of the space, while opening windows provides a source of drier air, creating a flow that facilitates the ventilation process. This strategy is integral in restoring a safe and healthy indoor environment following water intrusion due to flooding.

In contrast, sealing windows and doors limits airflow, which can exacerbate moisture problems. Reducing airflow intentionally may lead to stagnant air and high humidity, creating a conducive environment for mold growth. Leaving the area closed off entirely would also prevent necessary air circulation, thereby hindering the drying process and prolonging the risk of mold contamination.
