Class description
This hybrid presentation will include elements the new ASHRAE standard, 241, Control of Infectious Aerosols, which defines minimum requirements for measures to reduce the risk of transmission of pathogens in buildings.
When it became acknowledged that indoor air was the primary mechanism for SARS-CoV-2 transmission, the need for practical industrial hygiene and ventilation expertise became evident. Several approaches derived from the practice of industrial hygiene are described - assessing exposure using traditional chemical emission models combined with aerosol science and medicine, ventilation assessments using tracer gas studies, and risk assessment modelling and defining target goals for both administrative and engineering controls of infectious aerosols via a new ASHRAE standard, 241, Control of infectious Aerosols.
