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 essential for mold prevention after a structure fire. Removing water quickly and drying thoroughly address the obvious moisture, but without actively controlling humidity, residual moisture in the air and within walls can allow mold spores to germinate and grow later on.

Humidity control—using dehumidification and other moisture-management methods—prevents this by keeping the environment less favorable for mold. Cleaning helps remove residues and spores, and ventilation supports drying, but neither alone guarantees prevention if humidity remains high. So the step missing humidity control is not part of effective mold prevention, because without lowering humidity, the conditions stay ripe for mold to develop.
