Explosions versus exposure ?    Both are potentially damaging.   Both warrant caution.

I think explosion can be prevented by keeping the volatile chemicals
in a sealed metal tin when not pouring them AND by checking  for any
potential spark source, as previously mentioned, before each and
every use.     This means powering off all heaters using fossil fuels and wireless equipment.   It also means humidifying the air during the heating season.

I already keep my cooking oils in a sealed metal tin except when pouring them into the skillet, to minimize risk of fire.

It is the longterm exposure that concerns me.    Accordingly, I will
ONLY use acetone/denatured alcohol outdoors until I talk to my sister.
(My sister has been a beautician for decades, and uses acetone daily in her work) or until I am convinced there is no risk to my body.   If I had
an integrated chemical fume hood/evacuator to suck fumes away from the worksite, I would not be so cautious.    But I do not.   So instead, I will use my screened-in porch.
