Acetone and MEK are both hazardous for human contact. Putting either one on
your hands will result in the solvents getting in your bloodstream within
seconds then your kidneys. Wear proper protection (respirator, gloves) or
use another product.

Can anyone comment on the _relative_ nastiness of acetone and MEK, please?
Being about to start building, I'll be getting one or the other in the next
week. I don't mind using more solvent and paying more money if that means
less risk to my health - and Tony's comment on MEK show sound reasons for
concern.
Thanks for any help anyone can offer.
Regards,
Jeremy

I'll add a caution here about MEK which hasn't been voiced on the group
for a few years. This is an extremely strong solvent and, like acetone,
is capable of passing through the pores of the skin.
Effects of methyl ethyl ketone on human health depend on how much MEK is
present and the length and frequency of
exposure. Effects also depend on the health of a person or the
condition of the environment when exposure occurs.
Breathing MEK for short periods of time, such as when painting in a
poorly vented area, can adversely affect the nervous system. Effects
range from headaches, dizziness, nausea, and numbness in fingers and
toes to unconsciousness. MEK vapour irritates the eyes, the nose, and
the throat. Direct, prolonged contact with liquid methyl ethyl ketone
irritates the skin and damages the eyes.
When using MEK (or acetone) always wear protective gloves and use a face
mask and goggles. Never use MEK or acetone to clean your hands.
Build safe.
