We will now be checking out keys to those interested in using the lab afterhours and on the weekends. Please see Ryan before 4pm the day you plan to use it and you will be issued one. Please return it the next day (with exception to the weekend) to make it available to other users. The doors will be locked during the week around 6pm. If you do not have an afterhours key you will be locked out if you leave the cleanroom and this could result in a safety issue if equipment was left running. Key holders will be responsible for locking up and shutting down if you are the last one in the lab.
