Guidelines on Mold Assessment and Remediation
Fungi (mold) are present almost everywhere. In an indoor environment hundreds of different kinds of mold are able to grow wherever there is moisture and an organic substrate (food source). They can grow on building and other materials, including: the paper on gypsum wallboard (drywall); ceiling tiles; wood products; paint; wallpaper; carpeting; some furnishings; books/papers; clothes; and other fabrics. Mold can also grow on moist, dirty surfaces such as concrete, fiberglass insulation, and ceramic tiles. It is neither possible nor warranted to eliminate the presence of all indoor fungal spores and fragments; however, mold growth indoors can and should be prevented and removed if present.
Comprehensive guidelines addressing assessment and remediation of mold growth on structural materials in commercial, school, and residential buildings. This guide is intended for housing and maintenance staff. In depth topics covered include assessment, safe remediation procedures, worker training, and an appendix on health effects of mold in indoor spaces.
