Many of our hoods and enclosures have pressure switches on the blower
intakes that sense a failure.  We still check with a velometer each
month and service the systems (belt changes, etc.) every six months
regardless of performance.

early Fume Hood Monitoring-Automated system


 From a safety
 standpoint, I would highly recommend a secondary  
inspection.

It will not only confirm that your safety controls are functioning
  
properly, but also make the Students & Faculty more confident in  

their working environments.

This should apply in all fac
ilities which utilize ventilated  
enclosures, and not specific to-in 
this case-Dominican University.

Respectfully,
