Abstract
A method and apparatus for controlling a fume hood. A containment condition, i.e., a condition that may affect containment of potentially harmful substances in the hood, may be detected, and information regarding the detected condition sent by wireless signal. A fume hood controller may control at least airflow in the hood base on the information contained in the wireless signal.
