The negative affects of the chemical are dependent on the amount of Xylene in the mixture you're using. It may not be a pure solution. Other chemicals in the solution could depress Xylene's ability to vaporize, which would keep you from being exposed through inhalation. I hope you are wearing gloves! Always be sure to change them if you spill any on you. I would drink a lot of water and just rest so that your body can recover from the acute exposure. If you don't feel noticeably better after a day, I would be concerned.

Keep in mind that if your type wash is not pure Xylene, the flash point will be higher than 70 degrees.

Your best bet, if you're really concerned about this, is to find out what type wash you are using and the amount of Xylene in it. I would then e-mail someone withing your school's chemistry department and ask if that kind of mixture could be dangerous in the environment you're in.

I'm the one who just recently inhaled toxic gas, stop copying me! lol!
