The importance of different routes of transmission for SARS-CoV-2 is an ongoing area of research. There is growing evidence that the SARS-CoV-2 virus remains airborne in indoor environments for hours, potentially increasing in concentration over time. As a result, lowering the airborne concentration of SARS CoV-2 by means of ventilation and filtration can play a role in controlling indoor transmission of the virus that causes COVID-19, in addition to social distancing, wearing of face coverings, and surface cleaning and disinfection. To assist our clients in determining the effectiveness of their cleaning protocols and HVAC operations, we are offering the following industrial hygiene testing.
- Collecting of surface and air samples for the SARS-CoV-2 (COVID-19) virus. We believe that both types of sampling are necessary to assess potential contamination (surface and airborne).
- There are no regulatory limits or recommended guidelines at this time for SARS-CoV-2 levels in environmental samples (air, surface, and water). Sample results are reported as a qualitative response for SARS-CoV-2 detection, meaning the lab report will indicate the presence (Detected) or absence (Non-Detected) of viral agents in the sample. It is important to note there is no way to determine viable vs. non-viable SARS-CoV-2, meaning the measured viral genome in the sample does not indicate whether they are infectious or noninfectious. If more information is needed on the sample analysis and reporting, please contact us.
- Validate HVAC and Filtration Systems for Aerosol Transmission Risk with veriDART™ This liquid aerosol-based solution uses DNA tracers to safely mimic the composition and mobility of viral aerosol to measure the effectiveness of ventilation and filtration for aerosol contaminants.
These tests can provide specific information on the cleanliness in buildings and the effectiveness of HVAC systems. Check out our website. We stand ready to assist you implementing all CDC, OSHA, state, and local COVID-19 guidelines across the United States.
