[Several people have sent me notes suggesting that I
am being a bit cavalier....]

The MSDS does look a little ominous.

However, ventilation should be enough. A hood would be
perfect, but an open window with a breeze might be
fine. People burn antifreeze in their cars all the
time, sometimes for months without any long term
effect. Similarly sometimes a break in the heater core
will send it out the defrost vents and coat the
windshield. This doesn't seem to be harmful either.

I am actually more worried by the fire risk. It has a
relatively low flash point. A Bunsen burner would be a
real risk. Only a hotplate would do.

Perhaps a switch to propylene glycol would be better.
There are coolants like

that are in fact made with propylene glycol. It's MSDS
is a lot less frightening.
