I used to install the stuff - and deal with the old linoleum that was yanked up. The smoke is putrid, not to mention the glues that are on the back. The smoke is definitely toxic. I get headaches like you wouldn't believe when someone burns it.
Not a good survival idea, but I guess you never know until you ask, eh?
