A mold control program should include all of the following factors except:

A mold control program is vital for maintaining indoor air quality and preventing health issues associated with mold exposure. The best practices for controlling mold typically include various cleaning and disinfecting methods, each chosen based on its effectiveness and safety.

The correct answer focuses on a practice that may not align with effective mold control. Spraying with a 1000 mg/1 quaternary ammonium compound could be less effective than other methods for several reasons. Quaternary ammonium compounds (quats) can be useful as surface disinfectants but may not penetrate porous materials effectively or eliminate mold spores thoroughly. Moreover, the concentration indicated may not be adequate compared to other solutions designed for mold remediation.

In contrast, the other methods mentioned relate to more established practices in mold remediation. Using a sodium hypochlorite solution at a higher concentration has been shown to be effective at killing mold on non-porous surfaces. Regular cleaning with alkaline detergents helps remove mold spores and prevents regrowth. Furthermore, the regimen of re-spraying with quaternary solutions at lower concentrations can be part of a periodic maintenance strategy to keep mold at bay once the initial remediation has been done.

Therefore, the answer highlights a method that lacks sufficient effectiveness compared to the others that are more
