Which step is not part of mold prevention after a structure fire?

• A. Rapid water extraction, thorough drying, humidity control, and cleaning
• B. Rapid water extraction, thorough drying, but no humidity control
• C. Only cleaning
• D. Ventilation only

Answer: (B)

Moisture control is central to preventing mold after a structure fire. Mold needs damp conditions to grow, so the prevention approach relies on removing water quickly, thoroughly drying all materials, cleaning contaminated surfaces, and actively maintaining low humidity with dehumidifiers and proper airflow. If humidity control isn’t included, even fast water removal and drying can leave damp environments that support mold growth in hidden pockets. That omission makes the method incomplete for mold prevention. Ventilating alone or cleaning without addressing moisture won’t reliably prevent mold.
