The IICRC Recommendations for Water Damage Restoration: What Homeowner's Should Know About the Appropriate Amount of Drying Equipment to Use
The IICRC, which is an acroynym for the Institute of Inspection, Cleaning and Restoration Certification, has certain guidelines that are followed by mold and water restoration remediators. Updated editions are often released that keep industry professionals apprised of the most pragmatic and efficient remediation tools and exercises.
In the 3rd edition, the s500 Standard and Reference Guide for Professional Water Damage Restoration, there are references to the appropriate amount of drying equipment to use on a property, relative to the damage experienced. Various algorithms are used to calculate the appropriate amounts, which are delineated in the following classes:
The appropriate drying method would be determined based off of an inspection. According to industry experts, the most common 'class' documented is Class 2. The following levels of drying are associated with each class:
This is a summation of the general drying techniques after an area has experienced water damage. It is recommended that, if one has experienced a great amount of water damage, they consult with an IICRC certified professional to have restoration work completed in the property.
Often, mold is discussed in various public forums, but one of the most imperative points of discussion tends to be omitted: mycotoxins. Mycotoxins are essentially why we study the potential human health effects of mold.
Mycotoxins are secondary metabolites (a byproduct of their metabolism), which derive from mold, which have the potential to cause harm (pathogenic) towards both humans and animals. There are myriad mycotoxins which are of interest due to the potential harm they can cause; "aflatoxin, citrinin, ergot akaloids, fumonisins, ochratoxin A, patulin, trichothecenes, and zearalenone" (Bennett & Klich, 2003). It is believed that the effects of mycotoxicoses are akin to those of being exposed to being exposed to such agents as pesticides or various heavy metals.
The term 'mycotoxin' is derived from a veterinary emergency, which occurred in England during the 60's, when an estimated 100,000 turkey chicks died. It was discovered that the groundmeal, which the turkeys were being fed, contained secondary metabolites (mycotoxins) from a present Aspergillus mold (Bennett & Klich, 2003).
The main type of mold that concerns professionals (in relation to mycotoxins) is Stachybotrys Chartarum, which laymen often refer to as 'black mold'. According to a research paper by Dr. Sean P. Abbott,
"The first cases of human stachybotrytoxicoses were a result of inhalation exposure of the spores by handlers of contaminated hay and straw. Without adequate PPE, remediators of mold-contaminated buildings are at similar risk of high mycotoxin doses" (Abbott, 2002).
Mycotoxins are still being studied, and the potential health effects are still be corroborated by scientists, especially in terms of potential carcinogenic effects. To read more into mycotoxins and mold, please find the following sources below.
