Mold: Potential Threats Sprout in a Watery World
Published in Ed Bas, Indoor Air Quality, 2020
As part of routine building maintenance, facilities should be inspected for evidence of water damage and visible mold. The conditions causing mold (such as water leaks, condensation, infiltration, or flooding) should be corrected to prevent mold from growing.
Indoor Air Quality

There are many different types of mold. Some molds can trigger allergic reactions or asthma attacks in individuals sensitive to molds. Some species of molds produce toxins called mycotoxins which can cause a wide range of health symptoms in people, some very serious.
Air Handling Systems for Cleanroom Control
Published in Kenneth E. Avis, Sterile Pharmaceutical Products, 2018
The relative humidity specification being used in most facilities in the United States is 45 percent ±5 percent. This condition is achievable under almost all outdoor air conditions. Maintaining a constant, relatively midrange humidity is important for several reasons: Humidities above 55 percent can cause personnel perspiration and increased particle shedding.A lower humidity helps limit mold growth.Higher humidities (above 50 percent) encourage oxidation and rusting.Very low humidities encourage electrostatic charging of surfaces, particularly plastics.

Reviews of the scientific literature have concluded that exposure to high levels of mold contamination is associated with adverse health effects, especially for people with asthma (WHO 2009; Kanchongkittiphon et al. 2015; Osborne et al. 2015; Thacher et al. 2017; Mendell et al. 2018). Therefore, standardized and objective methods are required to quantify mold contamination in homes. To fill this need, the Environmental Relative Moldiness Index (ERMI) was created (Vesper et al. 2007).

Epidemiological studies have demonstrated an association between exposure to mold-contaminated/humid indoor air and exacerbation of respiratory diseases with increased inflammatory status, such as asthma (Baxi et al. 2016; IOM 2004; WHO 2009).
