My understanding is that the serious safety warning that you mention
applies to MEKP, Methyl-Ethyl-Ketone-Peroxide, not the solvent MEK.
MEKP is the catalyst supplied with polyester resin to set it off.
Not withstanding, splashing MEK around can't be good.

MEK is about 1000 times the toxicity of acetone which isn't terrific itself.
I saw a safety note about MEK some years ago. The note said that if
you get a splash of MEK in your eye, you have about 15 seconds to wash
it out. If you don't do this, the MEK will eat away at the cornea and
at some time in the future, possibly 15-25 years, you'll start to lose
the sight in that eye.
I have not seen this warning since, but I avoid MEK if at all
possible, and if not, use serious eye protection like a full face mask
rather than goggles with ventilation holes.
We used some MEK based ink in an industrial inkjet printer some years
ago and abandoned it because it gave everyone in the room a headache.
