Everyone, The custodial staff will start spraying the door handles, flat surfaces, and any touch point in public areas. They will also be spraying the door handles on all offices and labs. Please leave the doors alone until they are dry. They may prop your door open for a little bit while it is drying. This is happening all over Purdue campus, so please be aware. Let me know if you have any questions. Thank you, Mary Jo Totten Birck Nanotechnology Center/Purdue University Building Logisitics Coordinator 1205 West State Street Office BRK 1220 West Lafayette, IN 47907-2057 (765) 496-1173
