What kind of safety laws are there for woodshops?

My roommate took it upon himself to build a woodshop in our garage. He mostly makes guitars, which he has gradually turned into a business (with a business license and everything). We have 5 people living in this house, and the one roommate who made the woodshop pretty much did so without every asking anybody if they were okay with it. It is often times very loud, and a lot of the time makes the rest of the house smell like sawdust/burning wood.

The rest of the roommates and I are pretty fed up, and we've slowly made some bargains with the roommate with the woodshop, such as him paying an extra $100 on rent because he basically claimed the garage, and we also got him to agree to pay $50 extra for electricity monthly since he added a welding shop onto his woodshop, which often times surges all of the power in the house so that we have to go and reset the fusebox.

I'm curious as to whether or not there are any safety laws regarding woodshops, especially in a home, that could apply here. I'm almost certain if there are such laws, my roommate is probably breaking all of them. Basically we are at the point where the roommate with the woodshop acts as if he has the right to have this woodshop in our garage, and there's nothing we can really do about it. I'm ready to report his shop if necessary. Any information would be helpful!
