The IH program trains technical professionals and scientists committed to preventing job-related disease and injury. The program’s goal is to educate committed and passionate industrial hygienists with both a firm theoretical background to enable growth and flexibility in our rapidly changing world.
The objective of this study was to measure particulate matter (PM) total loss rates in three older (1940s, 1960s, and 1980s) elevators in California during two phases and three low-cost intervention modes. Tracer gas decay and <2 μm aerodynamic diameter nontoxic NaCl particles (PM2) were used to calculate PM2 loss rates. The NaCl particles were considered surrogates for smaller particles carrying SARS-CoV-2. Empirical PM2 loss rates were paired with modeled dynamic scenarios to estimate SARS...
