ABSTRACT
A 1989 National Institute of Occupational Safety and Health (NIOSH) study revealed that only 5% of Indoor air quality (IAQ) complaints were related to microbiological contamination, but more recent studies have shown that there is an association between bio-aerosols and increases in IAQ complaints. Wet surfaces encourage mold growth, which discolors surfaces, leads to odor problems, deteriorates building materials, and may cause allergic reactions and other health problems in susceptible individuals. Mud leaves things dirty and the contaminants that may be contained in this mud can pose the potential health threats. Temporary ducts can be connected in such a way that the central blower removes the air from the building and discharges it through a temporary duct installed through a window or other opening. This procedure should only be attempted by individuals confident in their ability to rewire the electrical systems.
