Hi,
Be very aware of self-closing hoods. If they fail this is very serious.They may not have stops and can slam closed.
I would suggest using a conventional hood rather than a self-closing hood that relies on a motion sensor.

Investigate further if you see the sash propped up with a piece of wood, test tube rack, hot plate, etc....
There is likely a failed hood sash.

Stay safe in the storms if you are on the East Coast.

Hi Monique!

Most manufacturers of hoods want to assist customers with these problems. The hood mentioned here may even have the counterweight system under some sort of warranty. 

With such failures, first step should be to contact the manufacturer.

Subject: [DCHAS-L] Fume Hood Sash Mechanism Inspections

Hello Everyone,
 
Has anyone experienced issues with sash mechanisms?  I had one fail yesterday from what initially appears to be failure of the belt of the counterweight mechanism.  These fume hoods are fairly new and I am wondering how often it is recommended that these mechanisms be inspected.  And, does anyone have a written recommended procedure for such inspections that they are willing to share?
 
Thank you,
 
Monique
