Your post warrants a lot of thought..You're a very smart & clever man to think about safety issues (especially with all of those kids)..I don't think there's anything flammable in or around acrylics, so no worry there-- but as for proper venting by all means get as much air ventilation as you can!! Wearing a good quality face mask is even advisable..there have been several previous posts with advise on this subject, maybe someone else can direct you to them.. this is always a good question, so until your comfortable with the answer you need to keep asking it..to be honest with you, my work area suffers from safety neglect, so I would be keen to hear how others would solve this problem--I have a built-in squirrel cage fan faced out of an open window & that's about it..
