1. There are more than 100,000 species of mold. Most types that are routinely found are not hazardous to healthy individuals. But too much exposure or certain types of mold could cause allergic reactions, asthma, rashes and other respiratory complaints.

2. There is no practical way to eliminate all mold and mold spores indoors. The way to control indoor mold growth is to control moisture.

3. If mold is a problem at home or in school, clean up the mold and eliminate sources of moisture.

4. Fix the water leak to prevent mold growth.

5. Reduce indoor humidity (to 30%-60% ) to decrease mold growth.

6. Clean and dry any damp or wet building materials and furnishings within 24-48 hours to prevent mold growth.

7. Clean mold off hard surfaces with water and detergent, and dry completely. Absorbent materials like ceiling tiles, plasterboard or wood, may need to be replaced.

8. Prevent condensation on cold surfaces (i.e., windows, pipes, exterior walls, roof or floors) by adding insulation.

9. In areas where there is a perpetual moisture problem, do not install carpeting.

10. Molds can grow on virtually any substance, providing moisture is present. There are molds that can grow on wood, paper, carpet and foods.
