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.
