Water: friend and foe.

With a basic knowledge of the origin and transport of moisture, psychometrics, and the use of properly calibrated diagnostic tools, an EM can not only determine the origin of many moisture problems (and indoor air quality complaints), but also aid infection control efforts by minimizing microbial growth. In future issues of HHMM, CHEM will introduce the EM to flood and moisture mitigation procedures, as well as training courses and outside contracting services that should be used as an integral portion of a healthcare facility's emergency preparedness program.
