Full Description

Experiments were conducted in a controlled environment of a scaled test room. Nebulizer operated at 2L/min for one hour resulted in a spike of particle count for an hour after approximately three hours of release. Particle count highlighted the difference in two regions of the scaled test room where air flow was minimal. Impingers monitored concentration levels around the mannequin, lower region of the scaled room. Sustained increase was noted after three hours of release on the side the mannequin where the nebulizer was operated. Particle numbers returned to background levels after four hours.
