Context

Background

On February 17, 2022, a reported gas leak forced the immediate evacuation of Weniger Hall on the Oregon State University Corvallis campus. Weniger Hall is the primary mathematics building on the OSU campus, and the evacuation disrupted classes in progress. The OSU emergency alert system published the Corvallis Alert in real time via the @oregonstate Twitter account, providing the verbatim evacuation instruction to follow. NW Natural Gas utility crews and the Corvallis Fire Department responded to assess and repair the leak. According to the Gazette-Times (Corvallis), the all-clear was issued roughly 35 minutes after the initial report, with normal activities resuming in the building by approximately 1:30 PM PST. OSU has had a pattern of gas-related building incidents: a similar contractor-hit gas line incident in September 2021 closed three campus buildings, and an acetylene leak previously forced closure of another campus research building. The Weniger Hall event is notable because the @oregonstate Twitter alert was issued before most students and faculty even smelled gas, demonstrating OSU's shift toward social media as the primary rapid-notification channel for localized campus hazards.
