Emergency Notifications
Emergency Notifications are sent via several methods to warn the University community of imminent threats or disruptions to campus services, such as class cancellations. Alerts are only sent when there is a potential threat to safety or a major disruption to campus services, and for monthly tests.
Students, faculty and staff are encouraged to register their mobile phone number to receive texts. Additional email addresses and phone numbers can be added following the instructions in the Account Management section.
Alert & Siren Testing
CU Alerts are tested monthly on the second Wednesday of every month at 11:50 a.m. The test includes text messages, emails, social media posts, alerts.clemson.edu, desktop notifications and digital signage.
Clemson University's outdoor warning sirens, as well as the sirens around Oconee Nuclear Station (ONS), are tested quarterly on the second Wednesday of each quarter.
The final quarterly ONS siren test of the year will be a full, three-minute test. Due to the impacts of Hurricane Helene, this test has been rescheduled for Wednesday, October 30 and will occur between 11 a.m. and 1 p.m.
