Today a colleague asked for my opinion of the fume hood related device described at  This is an insert that roughly converts a standard chemical fume hood to a glove box - but with no glove in, or intended to be in, the gauntlet openings. This reduces the face opening and permits substantial reduction in ventilation volume.
The concept is intriguing and I wanted to ask if there is anyone on this list who has actual experience with this device, and, if so, what that experience might be.
My first thoughts about possible drawbacks were about combustibility (not just flame spread) and susceptibility to puncture or tearing when new or as it ages.  I also wonder about the possibility of accumulation of airborne contaminants in the work volume as a result of the lower ventilation rates this makes.
I would appreciate you insights based on actual experience with this or something similar.
