Fume hoods are ventilation equipment for the safe handling of harmful, toxic gases or vapors and are used to capture, seal and transfer contaminants as well as harmful chemical gases to prevent escape into the laboratory so that inhalation exposure is minimized by inhaling contaminants from the work area and keeping them away from the operator. Airflow within the fume hood is achieved by sucking air from the laboratory into the fume hood through an exhaust fan, which dilutes the contaminated gases within the fume hood and allows for low concentration dispersion after being exhausted to the outdoors through the exhaust system.
