Makes it kind of dicey to keep a quart of oil around then, doesn't it? Or do
they define the flash point of the "flammable"?

Oil in quart containers is exempted.

Normally, so many quarts of
engine oil is outside the "flammable" limits, or "flammable" is defined with a
flash point. Hell, TEFLON is flammable if you get the sucker hot enough {;-)

And what about parts washers? No solvent based cleaners allowed? That's why
the lid has a thermal fuse in it.

A gallon or two of Stoddard solvent
is ok, provided it is in an rated parts washer with the fusible link.
