Fume Hood Controls
There is a toggle switch on the wall of each lab (sometimes hidden behind appliances or other equipment) that regulates the airflow to each chemical fume hood. When the room is occupied, the toggle switch should be in the "occupied" position. To save energy, the last person leaving the lab should put the toggle switch back to the "unoccupied" position.
Each fume hood also has a face velocity sensor with an alarm. This sensor monitors the velocity of air passing through the fume hood and will alarm when an unsafe condition is detected. Please do not "mute" or tape over your fume hood alarm.
