Black Mold Overview and Prevention
 Teresa B Cross
Black mold is the common term for a genus of molds called Stachybatrus. Black mold is common in buildings and homes and grows wherever moisture is present. Found in cellulose based building materials, such as gypsum wallboard, ceiling tiles, wood and wood products, mold spores enter through window and door openings and outdoor air intakes from heating, ventilation and air conditioning systems.
Spores can also enter buildings by attaching themselves to clothing, hair and other means then dropping onto interior surfaces. Inside, these spores affix themselves to paint, wallpaper, insulation, drywall, carpeting, upholstery or fabrics. Combined with moisture from leaks, flooding and natural condensation, mold spores can grow and thrive.
Mold causes problems for people with allergies, immune suppression or lung disease and those who are susceptible to fungal infections. While some mold infestations are noticeable by their odor, most are discovered through visual inspection. Exposure to indoor black mold is not necessarily a health danger, but can cause unpleasant side effects such as nasal congestion, breathing difficulties or eye or skin irritation. Severe reactions often include breathing difficulties and high fever. The U.S. Centers for Disease Control and Prevention warns that people suffering from lung diseases have a higher likelihood of fungal lung infections.
Mold prevention should be a key element in regular building maintenance. Inspect surfaces for evidence of water damage and any visible mold. Clean solid surfaces with commercial soaps, bleach and water to remove mold, and use mold-killing cleaning products when possible. Keep humidity levels between 40 and 60 percent. Use air conditioning or dehumidifies in humid climates. Ensure adequate ventilation, especially in kitchens and baths, where exhaust fans can assist in preventing excess moisture. Minimize mold-susceptible interior finishes, such as carpeting in bathrooms, and remove and replace mold-infected porous materials, such as wallboard.
