Subject: Re: [Homebrew_PCBs] Re: Printer Is ACETONE a carcinogen

From: Steve Wright <wrights1@...>

Acetoneis not carcinogenic. It is liable to cause respiratory irritation and in higher concentrations will cause nausea, sluggish behavior and possibly drowsiness. Prolonged exposure may be toxic to the Liver over time.

Try mixing equal parts of Bromine and Acetone and it will cause breathing difficultues and affect the eyes - tear gas!

OK Norm, I _would_ now hesitate in this or any similar application. ;-)
I'm sure you had the proper clean stuff too, not some cheap fuel alcohol.

Depend on what you use the acrylic for.  MANY years ago (1970 or so) at the Lawrence Radiation Lab, we used a pair of massive acrylic beams  (2" thick, 24" wide, 10ft long) to support a 3MV Cockroft -Walton generator.  Wiped them down with alky before sealing them in the HV pressure vessel, then had to replace the entire assembly because of stress cracks.  If it's not a structural element, you're probably safe.
