IICRC S520-2008

Standard and Reference Guide for Professional Mold Remediation

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 or assess mold complaints, prepare remediation specifications, protocols or procedures, and manage remediation projects, (e.g., indoor environmental professionals (IEPs), other specialized experts) and finally, for other potential materially interested parties (e.g., consumers and occupants, property owners and managers, insurance company representatives, government and regulatory bodies). The S520 is a procedural standard. It is based on reliable remediation principles, review of available scientific and industry literature and information and practical experience. In addition, there has been extensive consultation with, and information obtained from, numerous other sources. The Second Edition of the S520 has been updated and rewritten. An additional Chapter and Section have been added covering Building and Material Science, and an additional section has been added covering Equipment, Tools and Materials. This document supersedes the IICRC S520 Standard and Reference Guide for Professional Mold Remediation (S520 First Edition 2003, 2004).
