The annual maintenance of the Pitt Public Health REES Environmental System will take place starting on October 22 and should last 4-5 days. All freezers/equipment on the system should be wiped down/sanitized and unlocked so that the technicians will be able to access the probes and provide proper calibration. This will include all freezers on the system: both in the Lab Pvilion and the Ground Floor Common Freezer Rooms. PLEASE NOTE THAT THE START DATE HAS CHANGED from 10/18.
