Re: [CAD_CAM_EDM_DRO] safety - pcb dust hazard

Hello Andrew,
I second Marris according to asbestos effects. Glass is not asbestos.
But after being once poisoned from glass dust. (couldn't breathe or
sleep for 3 days)
I threw out my blasting cabin and never used it again.
But PCboard material contains resins of all kind. And more then one is
said to be cancerigenous. Si if you can suck the stuff far away.
If you use spray mist the dust gets catched very good. And you carbide
mills or drills will last longer. Thats what I did when I was managing
the mechanical production of a electronics factory.
Best wishes
Sven Peter
