What additional difficulty might elevators pose during a drying project?

Elevators can indeed create an additional difficulty during a drying project primarily due to potential cross-contamination caused by pressure differentials. When an elevator is used, particularly in buildings with multiple floors, the movement of the elevator can create varying air pressures within the shafts and the surrounding areas.

This change in pressure can result in contaminated air or moisture migrating into previously unaffected areas of the building. For instance, if one area of the building has experienced water damage and is being dried, the movement of air could unknowingly transport contaminants from that area to other, cleaner parts of the building, complicating the drying process and potentially leading to the spread of mold or other adverse conditions.

By considering these factors, it's evident that managing elevators during drying operations requires careful attention to maintain the integrity of the drying environment and prevent further issues related to cross-contamination.
