[sdiy] dust from cutting epoxy/fibreglass boards

[Ben Lincoln]

Does anyone have a reputable cite for the claim that fiberglass dust is 
as (or even as close to as) hazardous as asbestos? I'm not finding 
anything definitive.

The dust is very fine, and I've worn a respirator when I've done circuit 
board cutting and drilling because I'm sure it's not *good* to breathe 
it in, but I imagine if it were *that* dangerous then blank boards would 
come with much more visible warnings about working on them.

Also, I've never heard of DIY electronics hobbyists exhibiting symptoms 
like asbestos-style warts or the more serious symptoms that apparently 
show up within about a decade of frequent exposure to asbestos.

I could obviously be wrong here, but I'd like to be sure before I apply 
to have my work room turned into a Superfund site :).
