fume hood
Chemical vapor containment
A fume hood is a ventilated enclosure in a laboratory that draws air away from the user and exhausts it outside, protecting workers from toxic vapors, dust, and fumes during chemical procedures.
The hood typically has a movable glass sash that can be raised or lowered to access the workspace while maintaining airflow: Always work with the fume hood sash at the proper height.
