This subject area addresses face and capture velocity of fume hoods, local exhaust, and general ventilation for confined spaces. For ventilation concerns of your overall work area please see the Indoor Air Quality Subject Area.

Ventilation such as fume hoods, local exhaust and ventilation are used throughout the laboratory for removal of airborne contaminants from the workers breathing zone. Common uses are in exhaust hoods to ensure that chemical mists, vapors and aerosols do not come in contact with the worker. Their use can be required as part of the Work Controls instituted during an experimental or work review.
