Phenolic burns as long as there is flame put to it.. Still a great need to be careful.

Your machine does not have to be large, it does not have to have vacuum, it simply has to have an MIA operator.
THIS!! I clench the trench every time i have to go back to the office (a mere 100yds in our commercial building) while the machine is running, knowing it only takes a minute to get a really dramatic accident on the table.

I'm not sure I'd want to trigger a dry chem fire extinguisher every time there is a little smoke, but would it be reasonable to hook a power disconnect up to a smoke detector? Say for those times the phone rings or nature calls and you don't remember to hit pause.

Is there anything like this available which can interrupt 2 hot wires?
Maybe that with a DPDT ?

The fire you see in the first post I was in 21k sq ft shop and less than 35 feet away. we had gone to the office to rework the file,

I ran a file for a person checking out a camaster to buy without checking it, and I have never done that since)
