doubtless correct. different people have different tolerances for any given toxin or irritant, and even in an individual that tolerance can vary over time due to other exposures, diet, etc. (for instance, sugar makes some substances less toxic, and ethanol makes methanol less toxic. in fact the treatment for methanol poisoning is iv ethanol to the level the patient can stand it. methanol itself isn't very toxic, but the body turns it into formaldehyde, however the same enzymes are used to metabolize ethanol so high ethanol levels reduce the amount of formaldehyde made and more methanol is eliminated unconverted). as far as epoxy, definitely best to avoid and reduce all contact with non-food chemicals. on the other hand, epoxy is a lot easier to see usually and i believe less toxic when thermally decomposed. actually i'm sure it's less toxic since when i was young and foolish i used a propane torch to recover chips from a board, producing nasty fumes (i did stay upwind, but still stopped quickly) and some of them even caught fire briefly. had they been super glue/fiberglass boards rather than epoxy/fiberglass boards i'm sure i wouldn't be around. of course it's always best to avoid decomposing chemicals with heat etc. or if you do to have proper respiratory and other protection. there certainly are no free rides in life. every thing has a cost, spend wisely.
