COVID-19 Testing is Now Available!

disinfection verification covid19

COVID-19 testing is now available to accurately detect whether the virus is present on a surface. The presence or absence of the viral genetic material on environmental surfaces are now being analyzed by several laboratories for SARS-Covid-19 using a process referred to as polymerase chain reaction (PCR) genetic testing for COVID-19 regarding disinfection.

Evaluating COVID-19 Test Methods

disinfection verification options for cvid19Recent studies have shown viable coronavirus can be detected up to three hours later in the air, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel. Cleaning of visibly dirty surfaces followed by disinfection is best practice for prevention of COVID-19 and other viral respiratory illnesses in your household and in community settings. Regular household cleaners are effective, including bleach solutions and alcohol solutions of at least 70% alcohol. The EPA provides a list of disinfectants effective against COVID-19.  Depending on the length of time in the facility and the areas traversed by the confirmed COVID-19 case, consideration may be given to using
a professional cleaning/disinfection service and extreme measures such as ozonation, UV disinfection, and/or ULV fogging. 

Any test method to determine complete disinfection of the virus needs to be evaluated carefully. Find out how that can be done here.

Coronavirus Surface Disinfection

disinfection verification options for covid19With the recent pandemic, there are a few different types of tests and technologies for surfaces and buildings being marketed regarding the verification of disinfection for the coronavirus.  Guzi-West staff are currently evaluating these, however at this time don’t feel that the available tests can absolutely determine the total disinfection of the virus from any given surface.
Any test method to determine complete disinfection of the virus needs to be evaluated carefully.  Will the test method directly measure the presence of the coronavirus? Will the test be measuring for simple proteins which may be already present in the environment?  Will it be measuring for DNA or RNA sequences that may relate to the virus, and can it differentiate between a live sample and dead sample that has been deactivated by sanitation? The best testing methods will actually culture and grow organisms from the surfaces and can determine if potential virus particles have been fully disinfected.

How Do You Read a Mold Report?

When reading a mold clearance report, one document from a laboratory will stand out. This is the air cassette readings report the sampling technician took inside and outside the containment. It will have a multiple mold species and spore counts present. That’s completely normal! No home is completely free of mold. The sampling technician would typically take 1-3 samples indoors and 1 outside. The outside serves as a baseline in which we compare all indoor levels against.

How to Better Understand Your Mold Report!

professional mold testing Arcata, CAYou have been through the complicated process of repairing a water-damage loss in your home. You have called the remediation team, who abated the mold and now have called a company like Guzi-West, who performs “mold clearances.” The remediation company has more than likely conveyed the results to you – either pass or fail.  If the area failed, you needed to schedule another mold clearance after more remediation has been completed. If the area passed, they were able to take their drying equipment and plastic barriers out. What does a passing or failing mold clearance mean? What are the criteria for a passing or failing a test?

Often asbestos can be found in materials like: linoleum, vinyl floor tile, insulation, joint compound (aka mudding), sheetrock, wall texture, sprayed-on fire proofing, and acoustical applications, such as ‘pop-corn’ ceiling applications.  Have some of these same building materials in your home or business?
