Hi, I'm a new poster, so sorry if this is in the wrong forum. My lab director asked me about one of our blood bank refrigerators that had a crack in the glass. She was wondering if it would have to be replaced. The door is double-paned glass and the crack is in-between these two panes of glass. The temp. doesn't seem to be affected by this crack. I was just wondering if anyone had any links to OSHA or CAP guidelines about whether or not it should be replaced. Thanks for your time. DCH
