You're probably right about better safe than sorry. Bear in mind though,
that you are located in a hotbed of emissions controls, and there's all
sorts of regulations about the volatile organic compounds (VOC) that can be
released. The days of sloshing acetone, lacquer thinner, or MEK around are
over, at least in Los Angeles. You can't even buy real oil based enamel
house paint any more, because it's too high in VOC. (Although I know people
who smuggle it in from Arizona... they claim at the checkpoint that they're
coming for California cheese <grin>)
