DIY and fiberglass and safety

Well, I'm still alive.

Generally, if it's not flying around in the air, and is contained, I don't consider it a problem.

You're okay as long as you keep it out of your pants and don't try to snort it.

Asbestos is way better... to give you a scare. Guns are likelier to kill you in the USA than Fiberglass ever will, though. Wonder if there is a NFA so that Fiberglass will not be taken away from the people?

It took a hundred years before the effects of asbestos came to light. So if you get a painful cough around Christmas 2102, you'll know what caused it.

It might take a while to air out the fiberglass resin smell however I don't believe there is a saftey issue.

I use fiberglass wrapped in plasic as the core with a couple layers of batting, and burlap covering it. I have had a canary next to one the traps for about a year, and it hasn't coughed yet.

F.A. Everest's "Sound Studio Construction on a Budget" has an appendix on fiberglas safety, saying essentially that it's safe, as Twl suggests. But not long ago I obtained some Coincident Troubador drivers and built little boxes for them, with generous advice from Coincident's Israel Blume, and they sounded boxy with fiberglas--which I'd put in without asking him. When I asked him how much to put in, he delivered a diatribe against fiberglas--bad for sound and bad for health--and told me to use polyester fiberfil, as in pillows, obtainable from fabric shops, instead. He may be wrong about health but he was very right about sound: with the polyester fiberfil replacing fiberglas, the boxiness was all gone. I've since wondered whether it would also do better in some other applications, like inside DIY Argent Room Lenses and perforated panel absorbers--but haven't made those changes yet. Fiberfil is expensive, but certainly worth it inside speaker cabinets, and maybe elsewhere too.
