As ever, please excuse the cross-postings.  I have a new researcher
whose topic of interest is composites.  She does lay-up and manufacture
of composites using various epoxies and resins.  She also tests
composites with various liquids with which the composites might come in
contact - jet fuel, de-icing liquids, etc.

We are renovating lab space for her and she needs a place to "lay-up"
various composite materials and vacuum bag the pieces to cure.  She has
plans to do work on a full-scale car bumper and an unmanned vehicle of
some sort.

Currently, they work with small pieces in a (very small) fume hood and
wear respirators when working outside of the hood.  I'm philosophically
uncomfortable with folks routinely wearing respirators.  We can engineer
out this hazard!

A traditional fume hood probably won't work.  Backdraft won't allow for
access all the way around the work piece.  We use down draft tables in
anatomy teaching but will traditional down draft work in this situation
with such a large surface area?

Lemme know what ya'll think.
