I would not trust wikipedia for anything related to my own life.
If you want reliable data, searcher "MSDS Acetone” from a reputable website.

>> I must echo the views of dangerous chemicals. A school friend was working on cleaning his motor bike engine. He was using a mixture of acetone, white spirit and trichloro??? . His father was using a grinder about 25 -30 feet away in the same garage. All of a sudden my friends overalls caught fire from the exposed splashed on chemicals. His hands were the worst burnt as he tried to take his burning overalls off. 18 months in hospital, 2 to 3 years of occupational therapy. 5 years before he was able to have assisted work. He needs repeated surgery as the scars on his hands shrank. The burning pants and underpants destroyed any chance of sex again, all gone or scar tissue.

>> I do use some of the above chemicals but made myself a fume cupboard/ paint spray booth and have a couple of fans to draw the fumes through to an outside widow and roof vent. I also have a small fire extinguisher in my work area (I do white metal casting as well) and under the kitchen sink. Never used them, except when they have date expired and have been replaced. A couple of times I started a fire in the backyard or BBQ and put it out with the out of date expired extinguisher. A useful learning experience.

>> I am a dentist and have work made form me by dental technicians. Many of the chemical the dental technicians use are nasty. I am aware that most of the dental technicians I used to know have died in their middle years and looked older than they should. I wondered if this was continual exposure to chemicals. I was visiting one dental laboratory where the fumes were overpowering and left the room almost immediately. There were 5 technicians in the room all day at the time. Only technician was older than me at the time. I know that at least 3 of them have died and the female never carried a child to term. This was 25 to 30 years ago.
