I haven't started resining yet but I will do it outside or in my bedroom with all 4 windows open and several fans (fans are not only for the fumes I live in Texas and it is still hot as hell here). As far as the safety of it everybody should look at the MSDS (Material Safety Data Sheet) for the specific resin you are using. It not only has toxicity levels but also the ppe (personal protective equipment) you should use, and what to do if exposed at what levels or entry routes. You can get free MSDS's on MSDS.com or call the manufacturer by law they have to provide one if requested. If you have any Safety related questions email me I am a Safety Man with a degree so it will not be a ******** answer. By the way the Noob Basics is very well written just needs something about the MSDS and it would almost be OSHA worthy lol.
