10 Things to know about Mold

Mold can be a very serious and dangerous problem. The first step in preventing and controlling mold is controlling moisture in your home.

Below is some important information that you should know about mold.

  1. Some possible health effects and symptoms associated with mold exposures include allergic reactions, asthma, and other respiratory complaints.
  2. It is hard to eliminate all molds and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.
  3. If mold is a problem in your home or school, you must clean up the mold and eliminate the source of moisture.
  4. Fix the source of the water problem or leak to prevent mold growth.
  5. Reduce indoor humidity (to 30-60%) to decrease mold growth by:
    • venting bathrooms, dryers, and other moisture-generating sources to the outside;
    • using air conditioners and de-humidifiers;
    • increasing ventilation;
    • use exhaust fans whenever cooking, dishwashing, and cleaning.
  6. Wet or damp building material should be cleaned and dry within 24-48 hours so mold does not grow. One may use water and a bleach mixture.
  7. Materials that absorb; such as ceiling tiles or sheet rock and are moldy may need to be cleaned or replaced.
  8. Prevent condensation: Reduce the potential for condensation on cold surfaces (i.e., windows, piping, exterior walls, roof, or floors) by adding insulation.
  9. In areas where there is a perpetual moisture problem, do not install carpeting (i.e., by drinking fountains, by classroom sinks, in bathrooms or on concrete floors with leaks or frequent condensation).
  10. Molds can be found almost anywhere; they can grow on virtually any substance or surface, providing moisture is present. There are molds that can grow on wood, paper, carpet, and foods.
