How do you guys deal with ventilation in your shop? Specifically, I'm getting ready to do a bunch of finish work. I was leaning towards water-based varnish to cut down on fumes, but now I've decided I want to go with a solvent based poly or laquer.
In the past, I've rigged up a spray booth of sorts using plastic sheeting for walls. I've only sprayed latex paint, so I just had a regular exhaust fan in the window. But if I'm spraying poly or laquer, I'm a bit nervous about the explolsion hazard with a regular fan. I've seen the "explosion proof" fans, but they're pricey...hard to justify for a even few projects a year.
Spraying outside is not an option. Am I putting myself and my shop at risk if I use a basic exhaust fan while spraying solvent-based finish?
EDIT: Just thought of this....
Would it be OK to put a fan on one side blowing air in and have an open window on the opposite side? Would that eliminate the explosion hazard?
