A good start would be to contact the laminate manufacturer(s) and
requesting a Material Safety Data Sheet - commonly referred to as a
MSDS sheet.  This should give you information about the flammability
of the material and and hazardous by products resulting from a burn.
You may want to contact all potential material suppliers because the
resin systems of the material do vary somewhat by supplier.
