Thanks Tony.
This is significant since I and presumably many others have a bottle of to be disposed of chemicals.
Hydrogen peroxide, hydrochloric acid and acetone can form an explosive. See:
Bertho
Accidental byproduct
Acetone peroxide can also occur accidentally, when suitable chemicals are mixed. For example, when methyl ethyl ketone peroxide is mixed with acetone while making fiberglass composites, and left to stand for some time, or when a mixture of peroxide and hydrochloric acid from printed circuit board etching is mixed with waste acetone from cleaning the finished board and allowed to stand. While amounts obtained this way are typically much smaller than from intentional production, they are also less pure and prepared without cooling, and hence very unstable.

Subject: RE: [Homebrew_PCBs] Chemical Exposure.
I think the danger was more that if you forget to put the lid on or spill some, that may wind up causing an explosion the ruins your day.
So I googled ‘acetone explosion’ to see how often that happens, and got distracted by seeing ‘Mother of Satan’ in the results: https://en.wikipedia.org/wiki/Acetone_peroxide. Note that just before the mention of ‘Mother of Satan’ there is a reference to PCB etching.
And now we’re all on the terrorist watch lists. Bugger.
