My 2hp dust extractor has a motor outside of the air stream and doesn't use the moving air within the fan to cool the motor. If your electric motor powered exhaust fan is exposed to flammable contaminated air and is not flameproof, then you're at risk! This includes axial type fans used to ventilate bathrooms. In theory, any spark-producing device, such as a switch, light, or radio, could trigger a solvent explosion? This applies equally to using an exhaust fan incorporated or exhausting from a booth. The alternative of not using a booth means solvents will quickly fill the room with fumes and overspray fog. A quick google of manufactured booths showed that these aren't cheap and way outside my budget. Therefore a spray booth mounted on my work bench was contrived. The next logical solution was therefore to spray within my garage/workshop without any detrimental health concerns. There's a few reasons why that is not a long term plan? Firstly winter has just started and below freezing temperatures are not conducive to spray painting! Secondly, it's not a good look for the neighbourhood to witness me releasing airborne contaminants into the air! I need to spray paint these objects, which at the moment means outside in the front of my house. I make wooden shoe shaped objet d'art about 300mm x 400mm x 100mm.
