Summary
editDescriptionNIOSH Aerosol Sampler (8743397933).jpg | This picture shows the NIOSH aerosol sampler as it was worn by healthcare workers during a study of airborne influenza. The inlet of the sampler is close to the mouth and nose of the worker, in what is called the worker’s “breathing zone”. This ensures that the sampler is collecting aerosol particles representative of those that the worker is breathing. The sampler is attached to the strap of a backpack that contains a vacuum pump to pull air through the sampler. |
