A crack has developed in the vertical sash of a 6 ft.. fume hood.  Here’s the descriptor from my researcher:
“Back when it occurred, the repair guys came out and their assessment was you would have to cut the venting above my hood to remove the sash, since it's such a tight fit, and so you would need to close the lab for a bit to do the repair.
  The repair guy said the crack wasn't a big deal and did not alter the integrity of the sash.  He also said it wasn't a safety violation, which was my main concern.  
Since the crack seemed like a cosmetic problem, rather than safety, and since I'm one in that hood, I figured I would have it repaired later and hopefully work it into a time when the hoods are down.”
I don’t think I like this characterization but I don’t know a whole bunch about laminated safety glass.  What do ya’ll think?
