Coronavirus Surface Disinfection

With 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.

Guzi-West Now Testing for Naturally Occurring Asbestos in California

In California, regulations have been implemented to protect the public from exposure to Naturally Occurring Asbestos. The most common type of NOA asbestos is chrysotile, other types such as tremolite and actinolite are also found in California.
