Certainly going to get dust! I have considered this question (about fumes) inside my garage. I live in a split-entry where the garage is under bedrooms. Right now, my forge is on wheels and I roll it outside, but If I didn't rent I would build a stove hood like in a commercial kitchen with perhaps an exhaust fan in the hood. And yes, I forgot about the co detectors. I have one, I just take it for granted as it's never gone off :)
