My Workplace Is Currently Re-sealing The Floor Joints In Our

My workplace is currently re-sealing the floor joints in our parking garage, which is creating fumes. I am 7 months pregnant and read that they could be using polyurethanes, which can cause birth defects. The parking garage obviously has some ventilation as it is not all enclosed. Do I need to be concerned about parking there and breathing the fumes a little bit everyday? I am worried about causing birth defects.
