Abstract
A fume hood system having a decommissioned mode. A fume hood may be required to maintain a minimum flow from its enclosure holding fume type substances via an exhaust external to the hood. However, if the fume hood is considered not in use or not containing fume type substances, it may be put into a decommissioned mode not necessarily having a flow requirement. This mode may be entered by pressing a sequence of buttons on a monitor, operating a switch, receiving a signal from a building management system, or the like, provided that certain criteria for non-use are met by the fume hood. The decommissioned mode may also be entered or exited automatically. Status of the fume hood, as to in-use or decommissioned, may be reported to a building management system for monitoring, reporting, and/or command purposes.
