CARPET & RESTORATION
Late in 2015, after much professional review,
the IICRC released the fourth edition of the
ANSI/IICRC S500 Standard & Reference
Guide for Professional Water Damage
Restoration and the third edition of the
ANSI/IICRC S520 Standard for Professional
Mould Remediation. Following this was the third edition of the ANSI/
IICRC R520 Reference Guide for Professional Mould remediation.
SCRIA members, restoration companies, mould remediation
specialists and hygienists are encouraged to purchase and read the new
standard and reference guides. The documents have been written and
based on reliable remediation principles, reviews and experience.
The R520 Reference guide is in the new format, separated from
the S520 procedural standard document. So, make sure you order
both. The reference guide is important as it has principles in there
that allow us to better understand and apply the standards.
The ANSI/IICRC S500, S520 and R520 Standard & Reference
Guides for water and mould have had some significant changes that
ultimately change the way we dry, remediate and report.
A summary of the primary changes in the fourth edition S500:
• ‘Classes of water’ definition has been refined, providing a more
objective means of estimating the evaporation load in the building.
• Dehumidification formula has been upgraded with two examples
of calculations provided.
• Air mover calculation has had significant reworking. Calculations
based on the amount of wet, affected surface area, which provides
the required amount of air movement on all classes.
• Category of water loss has had some minor definition changes.
• Practical restructure of inspection and structural restoration section.
• New materials and assemblies section consolidates information
from three other chapters describing more than 80 materials
and building assemblies and how to deal with them in different
categories of water.
• Equipment, instruments and tools chapter provides better
understanding on equipment and instruments used, with multiple
• Building science, psychrometry, microbiology and drying
Technologies chapters have been strengthened. Psychrometry has
been rewritten, strengthening the science behind it.
• Some chapters have had minor wording and copy structure changes.
A summary of the primary changes in the third edition S520:
• Reference guide has been separated from the standard.
• Inclusions of international measurements.
• Further clarifications and strengthened rules in regards to negative
• Temperature extreme cleaning procedures should not be used as an
alternative to physical removal.
• Rewording of misting and fogging of disinfectants and further
• Company insurance information.
• HVAC systems and its use.
• All references and definitions have been updated.
• Post remediation evaluations and assessments and verifications.
It is recommended that everyone take note of the new changes and
understand them. If you are involved with water and mould, then
these editions will be an asset for you and your business.
The industry has been evolving for some years now, but more so
in recent years as third party groups expect the contractor to bring
their pricing down to meet the agreed pricing structures. These new
standards, if fully understood, allow you to justify your decisions as
a professional if questioned.
SCRIA looks forward to another year as Australia’s Association
for restoration professionals and cleaners. If you would like more

Restoration specialists to take
note of updated IICRC Standards
With the release of various updated Standard editions from the Institute of Inspection Cleaning
and Restoration Certification (IICRC), Scott McFadzen, president of Specialised Cleaning and
Restoration Industry Association (SCRIA) explains the changes and outlines the important
details of which restoration specialists should take note.

While managing humidity, spills and minor flooding are common
tasks in any facility, they should never be considered routine.
Not only can moisture damage floors and create slipping
hazards, but it can also pose a risk of microbial growth and
compromised indoor air quality. When you combine the elevated
humidity levels created by spills or flooding with normal room
temperature, mould can begin to grow in as little as 24 hours.
As such, every facility should have the tools to respond
quickly and effectively to water intrusions. These tools, in
particular, should focus on the proper use of air movement
Air movement is most important at the beginning of the
water project as this is when evaporation is most rapid (even
materials that absorb water quickly, such as carpet and
plasterboard, release water quickly). If one applies adequate
air movement–and more is better–during this time, the
evaporation rates increase dramatically.
However, this process won’t lead to faster drying if the
excess humidity isn’t removed quickly enough. That’s where
dehumidifiers come in. By creating dry air conditions,
dehumidifiers allow the evaporation process to continue
uninhibited. In particular, machines that incorporate low grain
refrigerant (LGR) technology can combat moisture problems
more effectively–and in a broader range of temperatures–than
conventional refrigerant units. LGR units can continue to provide
warm, dry air in conditions where conventional refrigerant
dehumidifiers simply freeze up and no longer remove moisture.
By properly applying air movement and dehumidifying
technologies, moisture from spills and flooding can be
quickly removed and the chances of microbial growth taking
