Antimicrobial Use During Mold Remediation

IAQS BiohazardThe goal of mold remediation is to remove or clean mold contaminated materials in a way that prevents the emission of mold and dust contaminated with mold from leaving a work area and entering an occupied or non-remediation area, while protecting the health of workers performing the mold remediation.  The goal is not to kill the mold it’s to collect and remove it.

 

The first step in solving an indoor mold problem is stopping the source of moisture. Next is to remove the mold growth.  Next is the proper cleaning and removal of mold contaminated personal property and building material. The proper method is the collection and removal of the mold. Improper methods for cleaning mold include the application of fungicides and biocides to kill mold. These methods may render the mold non-viable (dead or incapable of growth); however, the mold and its by-products can still elicit negative health effects. The mold is still and allergen in your home until its removed.

 

A mold spore is an allergen that may or may not have the presence of mycotoxins.  Some of these mold spores have the ability to germinate and may eventually grow to be a colony.  To prevent this we correct the moisture that was supporting the mold growth and wala the mold will not have the available moisture to grow.  Now all we have to do is collect the remaining allergens (aka mold spores) and remove them from the home.

 

If we simply apply fungicides or biocides to kill the mold so it won’t grow we still have the mold spore or allergen that may or may not have the presence of mycotoxins.  But…the mold spores are still in your home, still an allergen, still have the potential of containing mycotoxins, and are now completely covered in a poison, just Wonderful.  And the poisonous mold still needs to be removed.

 

New York City Department of Health

"The use of gaseous, vapor-phase, or aerosolized biocides for remedial purposes is not recommended. The use of biocides in this manner can pose health concerns for people in occupied spaces of the building and for people returning to the treated space if used improperly.

 

American Industrial Hygiene Association AIHA

The goal of remediation is removal of mold and the moisture source because: a) biocides do not alter mycotoxins or allergens; b) it is generally not possible to get 100 percent kill with biocides; and c) because of (b), the newly deposited spores, re-growth will occur after the biocides if moisture returns.

North American Air Duct Cleaning Association NADCA position on Sanitizing Ductwork Position on Sanitizing Ductwork

The EPA has not registered any products for sanitizing or disinfecting ductwork. Further, no fungicides are registered for use in ductwork. It is a violation of federal law to use a product in a manner inconsistent with its labeling. For antimicrobials, this law is the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Therefore, any claims of sanitizing or disinfecting ductwork would require the use of a product in a manner inconsistent with its labeling, which is a violation of FIFRA.

 

U.S. Environmental Protection Agency EPA

"The purpose of mold remediation is to remove the mold to prevent human exposure and damage to building materials and furnishings. It is necessary to clean up mold contamination, not just to kill the mold. Dead mold is still allergenic, and some dead molds are potentially toxic.

EPISODE 535: Oliver Threlfall - CEO Steamatic of Australia - A Unique Perspective on how the Global Restoration Big Dogs Play!
Over the past 30 years Oliver Threlfall has been totally dedicated to the cleaning and restoration industry. He studied biology at Deakin University- before commencing Steamatic in Melbourne, Victoria in 1986. He then completed IICRC (The Institute of Inspection, Cleaning and Restoration Certification) training in various modules and in addition took Microbial and Bioaerosol remediation training under the guidance of Dr. Tullis and Dr. Thulman of Duke University. Steamatic was formed in Australia in 1986 following requests from underwriters to establish proven claims reduction services that had been demonstrated overseas. They then transformed an established cleaning company into a specialist cleaning technologies firm. Oliver is the Steamatic of Australia CEO which makes him a very busy and connected man "down under".

EPISODE 534: Corbett Lunsford - The Home Performance Worskshop & The Worlds Highest Performance Tiny House on Wheels!
Corbett Lunsford, wasn't a home performance expert- he used to play piano for ballerinas. In 2008, he learned a few things very quickly: construction is unbelievably messy, most pros are over-rushed and under-paid, and homeowners end up suffering in small ways, for their entire lives in a house. None of this has to be so- we can opt out of the whole thing with performance testing. His goal is to package building performance so it can easily be understood and used by professionals and consumers alike, for better buildings worldwide. In 2009, he started teaching pros through the Building Performance Workshop and he has hosted over 300 YouTube videos and 80 interviews for the Building Performance Podcast. He also wrote the book Home Performance Diagnostics: the Guide to Advanced Testing, and developed the APT Reports software tool. In 2016 he and his wife Grace built the world's highest performance tiny house on wheels, the #TinyLab, and toured the US before settling down in Atlanta, Georgia. Along the way, they created the first TV series about home performance, Home Diagnosis, which airs on public TV across the U.S. Corbett, Grace, and their new baby went on a 13,000 mile, 34-city U.S. Tour from April 2016-January 2017 in the world's highest performance tiny house on wheels, the #TinyLab. Their mission was simple: to revolutionize the home market by teaching consumers and contractors alike to use scientific testing to prove the work gets done to quality standards. Each city on the Proof Is Possible Tour was sponsored by a local company that shared the passion for empowering homeowners and changing the game. Along the way certain cities shared in filming of the couple's TV show Home Diagnosis. They invited over 7,000 strangers into their home on the tour, and now live in Atlanta, Georgia.

EPISODE 531: David B. Corry, M.D. – Baylor College of Medicine – Fungi in Health & Disease
This week we welcome Professor of Pathology & Immunology and Medicine, David B. Corry, MD of Baylor College of Medicine, Michael E. Debakey VA Medical Center. We are looking forward to a fascinating discussion on Fungi in Health and Disease with Dr. Corry. Dr. Corry is a pulmonologist by clinical background and still practices, mostly focusing on allergic airway diseases such as asthma and sinusitis. Most of the time, he is an immunologist and his research focus is into the mechanisms underlying inflammatory lung and other diseases including smoking-related emphysema, asthma, and sinusitis. Among his groups contributions to science, they have shown how fungi cause allergic inflammation-largely through their release of powerful proteases. They have further demonstrated the ability of fungi to infect the mouse airway and produce a disease that is essentially identical to asthma and further demonstrated that common human disorders such as asthma and chronic sinusitis are often times, in essence chronic fungal infections. His group primarily relies on antifungal medications to treat their asthma and sinusitis patients. It has been revolutionary and they have published some of their experience, with more to come. Dr. Corry also recently published a paper on Candida and how it goes directly from the blood stream to the brain in mice. We will also talk about non respiratory health issues and fungi including the state of evidence on Alzheimers, Chronic Fatigue and other health issues sometimes blamed on Fungi. If you are interested in Fungi and Health don’t miss this show.
