4. S520 Preface This document is written for use by those involved in the mold remediation industry, primarily for mold remediation companies and workers, and secondarily, for others who investigate mold complaints, write remediation specifications, protocols and/or procedures and manage remediation projects.

5. S520 Preface IICRC S520 is presented in a two- part format: the procedural standard and a supplementary reference guide. The Standard is printed first within the document on colored pages, followed by the longer Reference Guide section.

6. 1.2 Purpose  Every 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.  Every 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.

7. Definitions: Standard of Care The IICRC S520 Standard Committee interprets “standard of care” to mean: practices common to reasonably prudent members of the trade who are recognized in the industry as qualified and competent.

8. Important Definitions Must: When the term must is used in this document, it means that the practice or procedure is mandatory due to natural law or regulatory requirements, including occupational, public health and other relevant regulation, and is therefore a component of the accepted “standard of care” to be followed. Natural Law: A law or body of laws that derives from nature and is believed to be binding upon human actions apart from or in conjunction with laws established by human authority; e.g., “wet always goes to dry if it can.”

9. Highly Recommended: When the term highly recommended is used in this document, it means that the practice or procedure is a component of the accepted “standard of care” to be followed, while not mandatory by regulatory requirement. Recommended: When the term recommended is used in this document, it means that the practice or procedure is advised or suggested. Important Definitions

10. Definitions: Normal Fungal Ecology That which is reflective of the types and concentrations of molds typically found in non-water damaged, environmentally well-maintained structures, and reflective of the ecological and climatic elements of the geographical region in which the building is located.

11. Contamination “Conditions” Condition 1 (normal ecology) – may have settled spores, fungal fragments or traces of actual growth whose identity, location and quantity is reflective of a normal fungal ecology for an indoor environment.

12. “Condition 2” Condition 2 (settled spores) – an indoor environment which is primarily contaminated with settled spores that were dispersed directly or indirectly from a Condition 3 area, and which may have traces of actual growth.

13. Definitions: 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.

14. “Condition 3” Condition 3 (actual growth) – an indoor environment contaminated with the presence of actual growth and associated spores. Actual growth includes growth that is active or dormant, visible or hidden.
