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

Usually a good idea to read the MSDS document for any chemical safety information.  Search with google for "msds acetone", and you will find lots of them.

In the summary section of the MSDS document, you will find the available Carcinogen assessment references for the chemical, if there are any.  This will probably cause you do more google searches (unless you are a chemist or industrial hygenist).  for Acetone, the assessment according to the ACGIH group is an "A4", which means "not considered carcinogenic to humans or animals".  Different chemical companies will write their MSDS documents with slightly different references, so you may want to reference a few of them, to get a better perspective.

Acetone may not be carcinogenic, but has lots of other health risks; you may want to read the MSDS in it's entirety (they usually run about  4 - 10 pages, in my experience), to get an understanding of what all the other toxic and acute health risks are, if you plan to use it...

fyi,
Tom
PS  Any other questions ("... what is an MSDS?" ), remember, google is your friend.  T.

I asked my sister about acetone.   She uses it everyday at the beauty shop where she works, doing fingernails, pedicures, hairstyling.    She said they don't have ventilators where it is used.   So I guess acetone is NOT known to be a carcinogen.

But remember what Keith said.    Keep your acetone in a sealed airtight container just to make sure your house doesn't catch fire when you aren't home.
