FUME HOOD WITH SASH LOCK AND METHOD OF AIRFLOW CONTROL ABSTRACT OF THE DISCLOSURE A laboratory fume hood with at least two vertically movable sashes that are operatively coupled together by a sash lock that prevents both of the sashes from being opened at the same time. Opening of one sash automatically flips a pivoted lock into locking engagement with the other sash. Thus, one of the sashes must be closed before the other can be opened. This prevents the excessive waste of heated or cooled room air being sucked out through the fume hood. - 1 -
