Towards an improved wind effect assessment for asbestos abatement: A methodology for reduced-scale experiments.

During building renovation or demolition, asbestos fibers can be released which can contaminate the environment, leading to potential occupational health and public health concerns. Strict asbestos abatement procedures and regulations are in place to mitigate this risk, which involve sealing the worksite and depressurizing it relative to the outdoor environment (i.e.

Ventilation and air cleaning to limit aerosol particle concentrations in a gym during the COVID-19 pandemic.
