My Daughter Who Is 24 Just Called Me And Said

My daughter who is 24 just called me and said she opened up a can of paint thinner and she did not realize that it had built up pressure in it. So when she opened it up she it kinda blew a lot air and paint thinner in her face and on her skin. Now she said she has white bumps on tongue and in her mouth, and throat is red. I told her to rinse her skin and contuine to do so. Also to watch her breathing and if her throat or tongue started to swell. Ive told her to go to the ER but grown kids do not listen. Ive never had this happen just trying to find out what to tell her to look for if gets worse. I know nothing about paint thinner poising. Please help
