Use Heat to Pasteurize Your Building
Heat does several things; however among its most significant processes is that it applies the theories of Pasteurization to structures. Pasteurization dates back to the mid-1800s with the ideas applied by Pasteur. He determined that by heating food product to a temperature of roughly 60ºC (140ºF) for many minutes, bacteria, viruses, protozoa, molds and yeasts within the food would be reduced to levels that might not cause spoilage to the food or be harmful to the health of the buyer. Pasteurization improved shelf-life of food products and more significantly, provided reduced levels of contamination which created safe consumption without food damage. Today, we at Rest Easy Mold Control use these principles for structures. Structural Pasteurization is a method in which the temperature of a building or portion of a building is increased to help eliminate the targeted organisms to acceptable levels with minimal structural damage.
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.
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.
– S520 Definition
The process of “Structural Pasteurization” is recognized and included in the “Glossary of Terms”. The concept of structual pasteurization and its identification as a remediation process is a significant acknowledgement of the technology:
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.
