Structural Pasteurization
Pasteurize your Building with Heat (TM)
ThermaPureHeat® does many things, but one important process is that it applies the theories of pasteurization to structures. Pasteurization dates back to the mid-1800s with the concepts applied by Louis Pasteur. Pasteur determined that by heating food products to a temperature of approximately 60ºC (140ºF) for several minutes, bacteria, viruses, protozoa, molds and yeasts in the food would be reduced to levels that would no longer cause spoilage to the food or be harmful to the health of the consumer. Pasteurization improved shelf-life of food products and more importantly, provided reduced levels of contamination allowing for safe consumption without damaging the food product. Today, ThermaPureHeat® uses the same principles for structures. Structural pasteurization is a process in which the temperature of a building or portion of a building is increased to a level that will reduce the targeted organisms to acceptable levels while minimizing damage to the structure. This is the basis for ThermaPureHeat®.

Adaptation of Structural Pasteurization to the IICRC S520
In 2008 the Second Edition to the IICRC S520 Standard and Reference Guide for Professional Mold Remediation was approved by the American National Standards Institute (ANSI) for publication. This revision was a work in progress for over four years. Numerous participants were involved in the process to develop a concensus document that reflected the opinions of industry experts, microbiologists, mycologists, public health experts, industrial hygienists, other scientists, remediation contractors and related industry professionals.
The S520 is a voluntary Standard and Reference Guide, but it is the single most significant document regarding the process of mold remediation. The document is written for use by those involved in the mold remediation industry – primarily for mold remediation companies and workers, but also for those who investigate or assess mold complaints, prepare specifications, protocols or procedures and manage remediation projects. It is also the primary document for materially interested parties such as property owners, consumers, insurance companies, and government and regulatory bodies. The S520 is the most significant published document governing the remediation of mold in structures, structural components, and/or contents.
Structural Pasteurization – S520 Definition
Page 227 – Glossary of Terms – Structural Pasteurization – An engineered process in which high temperatures are introduced to a structure or portion of a structure for the purpose of reducing bio-organisms to acceptable levels without damage to the structure.
Structural pasteurization is a process that will improve indoor air quality. It is significant that this recognition exists in an important standards development such as the S520.
