Molds are microscopic organisms that are present virtually everywhere in our environment. Outdoors, molds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees, but indoors, mold growth should be avoided. All that is necessary for mold growth to start on these materials is moisture. Molds reproduce by means of tiny spores. When these spores come in contact with water or moisture mold may begin to grow. Molds produce allergens, irritants, and in some cases, potentially toxic substances (mycotoxins). Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals, cause asthma attacks in people with asthma who are allergic to mold, and also irritate the eyes, skin, nose, throat, and lungs of both mold-allergic and non-allergic people.

Mold needs four factors to grow: spores, temperature, moisture, and a food source. Mold spores are always present in both indoor and outdoor air, and they can flourish in any ambient temperature from 40F to 100F (4C to 38C). You may not be able to avoid the presence of mold spores, but you can take steps to control the moisture and food sources mold needs.
As part of your overall mold-resistance
strategy, follow good moisture
management practices. Then choose
mold-resistant construction materials such
as paperless interior drywall products.
For added resistance, choose building
components that will retain as little
moisture as possible. Moisture-resistant
materials will cut down on retained
moisture. Source: University of Florida

* Potential health effects and symptoms associated with mold exposure include allergic reactions and other respiratory complaints.
* There is no practical way to eliminate all mold and mold spores in the indoor environment. The way to control indoor mold growth is to control moisture.
* If mold is a problem in your home or school, you must clean up the mold and eliminate sources of moisture.
* Fix the source of the water problem or leak to prevent mold growth.
* Reduce indoor humidity to 30-60%. Decrease mold growth by venting bathrooms, dryers, and other moisture-generating sources to the outside; using air conditioners and de-humidifiers; increasing ventilation; and using exhaust fans whenever cooking, dishwashing and cleaning.
* Clean and dry any damp or wet building materials and furnishings within 24-48 hours to prevent mold growth.
* Clean mold off hard surfaces with water and detergent, and dry completely. Absorbent materials such as ceiling tiles that are moldy may need to be replaced.
* Prevent condensation. Reduce the potential for condensation on cold surfaces (i.e., windows, piping, exterior walls, roof or floors) by adding insulation.
* In areas where there is a perpetual moisture problem, do not install carpeting (i.e., near drinking fountains, classroom sinks or on concrete floors with leaks or frequent condensation).
* Molds can be found almost anywhere; it can grow on virtually any substance providing moisture is present. There are molds that can grow on wood, paper, carpet and foods.
