Re: (ET) Capacitor removal... fridges and pcb's

["Max Hall" <maxo iname com>]

Are you sure? Usually it's the refrigerant (Freon up until very recently)
that they have to worry about. You can't squirt that just any ol' place
anymore, what with the ozone hole and all.

And do you guys know how easy and cheap it is to make Polychlorinated
Biphenyls? No wonder there's a gajillion tons of it out there. And, as a
non-flammable, non-conducting liquid, it was a pretty good choice as an
electrical systems coolant. Too bad about the health effects.
