Liquid Nitrogen tanks cannot be left in the hallway due to fire regulations.  We have someone who will pick up your empties and deliver your full ones between the hours of 3:00 and 4:30 PM M-F.  Please put your empty tanks outside your lab prior to 3:00PM and it will be picked up.  We cannot leave the full tanks outside in the hall, due to fire regulations, so someone must be in the lab to accept the full tanks and sign for them. If no one is in the lab, we will try and contact you by phone and leave a note on the door informing you of the attempted delivery. If you have any questions or concerns about your tanks, please e-mailt stacy or call x57781
