The thread down below on spray booths has me wondering who else may be skirting danger in a home made spray booth. And, how dangerous is it really?
I have (had) two spray boothes, both similar in design. Both are in outbuldings. Both use a pair of 1500 cfm attic fans. The fans are mounted low to the floor. In one case, directly in the floor with filters in front. In the second case in a 16" x 9' board that sets under a partly opened garage door. Both building are fairly large with the smaller one being 16 x 24 feet,. Both provide large inlet air openings. I always shoot towards the fans and filters. I have no special lighting or inlet filtering. I'm obviously at natures mercy when it comes to weather, heat, cold and humidity (and bugs). I use lacquer based finishes.
The fans are mounted low, because "Most solvent vapors are heavier than air and tend to collect in low spots." Curiously, many commercial spray booths have fans overhead, with both inlet and outlet overhead.
I've been using this setup for 15 years... hobbiest activities, with no problems. So how dangerous is this? Anyone have any stories about people that blew themselves up? Anyone else have a similar set up?
Be safe!
