AMT and Noisebridge and almost anywhere else say not to cut such materials
on the lasercutter. See:
I don't recall anyone saying that the rear space ventilation system was
acceptable for these categories of material either.
Another useful step would definitely be to put that list up by the
lasercutter, if it's not already there. I'd suggest taking this to the fab
list, where people have discussed this previously.
