Hygieneering recently provided COVID-19 risk reduction assessment services to a Chicago client at a dozen of their office facilities with portions that are occupied 24/7. The main components of the assessment were:
- An operations review and measurements of their HVAC systems.
- Indoor Air Quality (IAQ) baseline monitoring for carbon dioxide, temperature, relative humidity, carbon monoxide and organic compounds.
- Policy and performance review of the cleaning and disinfection services.
- Review of the client’s implementation of existing COVID-19 mask wearing, social distancing, and hygiene policies.
In addition, Hygieneering was able to accommodate a client specific request for COVID-19 surface sampling/PCR analysis in certain ventilation systems.
Using ASHRAE, OSHA, EPA, and CDC guidelines, Hygieneering provided the client with recommendations to improve their building’s conditions to help minimize COVID-19 spread in the workplace. Some of the issues observed included:
- Under-performance of the ventilation systems.
- Inadequate filtration
- Presence of COVID-19 genetic material inside their air handling units (two instances in over one hundred units tested). Hygieneering worked with the client to address the presence of the viral genetic material and to resolve the issue immediately. Follow-up testing for the viral genetic material was non-detect.
This multi-facility assessment was an adaptation of our standard Building Wellness Program, which is a proactive assessment to address indoor environmental quality to enhance occupant health.
