The IICRC has announced that it is revising the IICRC S520-2008 Standard and Reference Guide for Professional Mold Remediation. The draft S520 Standard was available from July 5 to August 19, 2013 for the first round of public review, and is available now for the second round of public review and comment.

The IICRC S520 is a procedural standard and reference guide for the remediation of mold damaged structures and contents. The IICRC S520 is based on reliable remediation and restoration principles, research and practical experience and attempts to combine essential academic principles with practical elements of water damage restoration for technicians facing “real-life” mold remediation challenges. The S520 is written for use by those involved in the mold remediation industry, and is the result of collaboration among microbiologists and other scientists, public health professionals, industrial hygienists, remediation contractors, restoration service companies, cleaning and restoration training schools, trade associations that service the professional restoration industry, allied trade-persons and others with related professional and practical experience.

The IICRC S520 draft Standard is available for review and comment as part of the ANSI 45-day public review period from March 13 to April 27, 2015. In addition, the draft S520 Reference Guide is also available separately during the same time period for informal peer review and comment. To access the draft Standard and Reference Guide and Comment Forms, visit All comments must be submitted to IICRC Standards Director Mili Washington at no later than April 27, 2015.
