Are you experiencing any issues from your exposure? Have you called your physician? Were you in an area with ventilation?
Since you already had the exposure, I would contact your physician. If you want any additional information about possible exposures to certain chemicals and their effects on your health, you can visit the Occupational Hazard website here http://hazmap.nlm.nih.gov/cgi-bin/hazmap_generic?tbl=TblIndustries&id=498.
Please keep us posted on what your physician says. Good luck.
