Dampness in basements, walls, carpets, and wood caused by flooding provides an excellent environment for molds to flourish. For some people, a relatively small number of mold spores can cause health problems. Allergic reactions are the most common health problem from mold exposure. When an individual or family returns to their home after a flood, it is important to thoroughly clean all areas of the house. Mold can be detected if there is an earthy or musty odor, or there may be visible growth.
Visible signs are discoloration on walls, carpets, furniture, and wood.
Mold growths can have a variety of appearances, ranging in color from white, orange, green, brown, or black. Unplug appliances and lamps, and remove light bulbs from their sockets. Also, remove the cover plates from wall switches and outlets that were water-damaged. If local building code allows, disconnect the wiring from the switches and outlets and throw the damaged units out. Otherwise, pull the electrical units away from the wall while leaving them connected.
