[SML] styrofoam

[Bill Conner]

Styrofoam, Dow's trademarked name for extruded polystyrene, is
flammable.  Because of that generally  its use on stages in the US is
restricted by regulations, like the Life Safety Code.  I have observed
though this is not very often enforced.

The MSDS seems to suggest its pretty safe to work with.
