Thank you Dr. Dermer and others for the information on the hazardous Chemicals. This person was a unit clerk and she tells me that she was doing the girls responsible for these patients a favor by answering their lights. Our hospital has great policies on exposure to hazardous materials. In fact they have to wear badges to warn them about the amount of exposure time when with these patients. I told her since she has no protection to avoid any exposure to them. Thanks again. Mary Ann from Madison Heights, Michigan
