I Was At My Job On Sunday When One Of

I was at my job on sunday when one of the managers were using, 'Goof oFF' supposedly a very strong toxic material. I was in the back when they were using it because it was quite strong when i got to the floor. I would say that I go a headache, but i've been investigating the product and the symptoms can be quitre severe, although not experiencing now, i'm worried for future possibilities. They were using this indoors for bout 2 1/2 hours. no fan, and very little ventilation. i that considered prolonged use, and should i get my blood work done? Thanks!
