Control Panels
Most fume hoods are fitted with a mains-powered control panel. Typically, they perform one or more of the following functions:
- Warn of low air flow.
- Warn of too large an opening at the front of the unit. Known as a "high sash" alarm, this is caused by the sliding glass at the front of the unit being raised higher than is considered safe, due to the resulting air velocity drop.
- Provide a method of switching the exhaust fan on or off.
- Provide a method of turning the internal light on or off.
Specific extra functions can be added, for example, a switch to turn a waterwash system on or off.

Famous quotes containing the words control and/or panels:
“Being a parent is such serious business that we dare not take it too seriously. Children are inherently funny. So are parents. We all are at our funniest when we are desperately struggling to appear to be in control of a new situation.”
—Lawrence Kutner (20th century)
“He sent for lancewood to make the thills;
The crossbars were ash, from the straightest trees;
The panels of white-wood, that cuts like cheese,
But lasts like iron for things like these;
The hubs of logs from the “Settler’s ellum,”—
Last of its timber,—they couldn’t sell ‘em,”
—Oliver Wendell Holmes, Sr. (1809–1894)
