Methods to Reduce the Impact of Aerosol Transport in Labs: Thoughtful Ventilation Design to Address COVID-19 and Other Airborne Risks
Dianthé Van Weerden, RWDI
As we learn more about how COVID-19 is transmitted, we look back on past global threats like SARS and H1N1, and consider a future where another health threat is likely. We can no longer treat ventilation systems as an afterthought. Occupants and researchers in a lab need assurance that the air they breathe is healthy and clean. As a result, the casual implementation of standard ventilation systems in labs may no longer be acceptable, and thoughtful ventilation design is a key part of keeping people safe in shared labs. The type of ventilation system in labs plays an important role in preventing the transmission of COVID-19 and other pathogens that are transmitted through respiratory droplets. This presentation will give the audience a better understanding of ventilation strategies to help reduce the risk of pathogen transmission in labs.
- Understand how droplets of different sizes move in a ventilated environment;
- Be able to describe different types of air distribution systems in labs;
- Recognize the merits and drawbacks of different air distribution methods; and
- Be able to explain how ventilation systems can be simulated and the limitations of those methods.
