Its not luck, Daryl, but, one does have to be smarter than the chemical at hand. The flash point on lacquer thinnner (the hottest solvent of the bunch I mentioned) hovers around 20 degrees. So I typically use that cleaner in the winter, when we have no shortage of days less than that. That dramatically cuts down on evaporation, as well. The shop is well ventilated, and another fan is on hand if needed.
Mineral spirits are flammable but are nowhere near what any alcohol or acetone is capable of-flash point on acetone is about -4 degrees if I remember correctly, and I still use that stuff for some operations. Cautiously. Not in the buzz cleaner, either.
Common sense goes farther than luck. But, as I posted earlier, if you are comfortable with water, go for it.

Best,
Ted
