> The glass was not tempered or safety glass, and it broke into large jagged segments all around his back. After slowly extricating himself there was, amazingly, no injury. So two lessons learned there - 1) horseplay = bad even if it's not in the lab proper and 2) those cabinets need safety glass; if they aren't being used it may be easier and will certainly be less expensive to remove the glass rather than replace it.

The same is true for glass in fume hoods, including the covers for the lights within the hoods. I?ve seen hood explosions lead to lots of flying glass splinters, either from the sash or the light cover. Lab workers always seem surprised to learn that fume hood manufacturers don?t explosion resistance as part of their design criteria for the average hood.
