1.2 Purpose1.2 PurposeEvery mold remediation project has unique circumstances and thus it is impractical to issue specific procedures that universally apply to every situation In extenuating circumstances, deviation from portions of this standard may be appropriate. Carelessness is never acceptable and
common sense and professional judgment are to be exercised in all cases.

Definitions: ContaminatedDefinitions: Contaminated
The presence of indoor mold growth and/or spores, whose identity, location and amplification are not reflective of a normal fungal ecology for an indoor environment, and which may produce adverse health effects and cause damage to materials, and adversely affect the operation or function of building systems.
