“…In a recent study, the use of PM 2.5 instead of CO 2 was investigated for estimating ventilation rates. Estimates made with the two tracers differed by less than 10% 42 . However, the limitations of relying on CO 2 levels to assess adequate ventilation also apply to relying on PM 2.5 levels.…”

Throughout the history of occupational health risk control, ventilation has been implemented widely as a tried‐and‐true method to reduce exposure intensity to airborne contaminants. Proper determination of the ventilation rate merits careful consideration when addressing concerns directed toward occupational health and indoor air quality in commercial buildings, albeit this does not translate well among the current engineering and scientific community. This article aims to facilitate a better understanding and proper determination of ventilation rates as a countermeasure for occupational health risk control. To that end, guidance is provided to select the appropriate ventilation rate for nonpandemic versus pandemic scenarios in terms of pertinent regulatory/professional codes and mathematical modeling tools. Limitations and assumptions of the models are summarized to facilitate proper application. Furthermore, the emerging DNA‐based aerosol tracing technology, which helps to verify ventilation efficacy, is discussed.
