SWIM wants to boil down maybe 2-2.5 liters of acetone using a hot water bath. There is a hood right above that he wants to have on (He has a glass sliding door next to it, he'll put a fan next to it for better ventilation). Is it safe to have the acetone vapors go through the kitchen hood?

Because if there's a spark, then concentrated acetone vapor should ignite furiously. Or are kitchen hoods specially made to not make sparks?

Well, swim went ahead and did it. Boiled about 2.5 liters with no problems. Not even that smelly actually.
 
Not really that generally smart. You were sucking solvent fumes over and around a fan and electric motor for however many hours it took to boil down that 2.5 liters.

Do not do this at home, kids, and I suggest you don't do it again this way either, Ethnochemist. If you must use electric motor ventilation (which is sometimes necessary with powerful solvents). It is best to have the motor and fan assembly situated blowing air INTO the room from a window or door. This way it creates positive pressure in the area that keeps solvent fumes moving out of any cracked doors or windows in the room, consistently.

Conversely it also keeps solvent fumes from being sucked towards, through, and around the electric motor ceaselessly while the solvent is being evaporated.
