Best practices for cutting foam?
What are people doing to cut EPS foam and control the dust and debris generated, considering the toxicity of the fire retardant chemicals in it?
Some argue the fire retardants are OK, because they don’t leach out of the foam much. But it seems to me that the environmental release is probably dominated by the dust and debris generated.
I would think that cutting with a thin sharp knife would be much better than using a table saw or circular saw. But are there easy ways to get as good as straight cut? What kind of knife? One made for foam, or a utility knife, or a bread knife? What about a hot-wire knife?
