Chemical Fume Hood Restrictions in Carrigan

The fume hood exhaust ducts contain heat exchangers. None of the fume hoods in Carrigan WIng can support acid digestions. Please do not heat acids in these hoods.

Fume Hood Airflow Monitors    

Some of the chemical fume hoods have SafeAire alarms that will sound if the air passing through the hood lowers to an unsafe level.

The readout on the hood monitor is based on colors; it does not show the actual airflow in lfpm (linear ft per minute). The airflow is at a safe level when the alarm readout is in the green. As the face velocity weakens, the monitor will warn the user with a yellow "warning" light, and eventually an "unsafe" level of red. The monitor alarm should sounds when the monitor is in the red.

Submit a Famis Work Order request if your monitor is alarming too frequently or not alarming at all; it may need to be re-calibrated.

Risk Management & Safety can test the face velocity of the chemical fume hood in your Carrigan lab at any time. Please email for this service.
