  "context": "Ben Reifel Hall is a large [South Dakota State University residence hall](https://www.sdstate.edu/buildings/ben-reifel-hall) on the east side of the Brookings campus. According to [The Collegian](https://sdsucollegian.com/32801/news/gas-leak-contained-near-ben-reifel/), SDSU's student newspaper, a sidewalk snow broom hit the side of a gas meter on the east side of the hall on the morning of February 4, 2026, causing a natural-gas leak. Interim Chief of University Police Michael Drake confirmed the initial Campus Alert went out at 7:30 a.m. CST, a containment update at 8:05 a.m. CST, and a final all-clear at 10:27 a.m. CST once Northwestern Energy resolved the situation. The Brookings Fire Department and University Police set a perimeter spanning from the Pius XII Newman Center toward the east side of Ben Reifel Hall while utility crews repaired the area. [SDSU's emergency management system](https://www.sdstate.edu/safety-security/emergency-management/emergency-status) was used to send the three-alert sequence. The episode is an example of a winter gas-leak response requiring multiple updates (containment is not the same as full resolution) across a nearly three-hour response window.",
  "keyFindings": [
    "A routine winter-maintenance task (a sidewalk snow broom) caused the leak by striking a gas meter at Ben Reifel Hall",
    "SDSU issued three alerts over nearly three hours: initial at 7:30 a.m. CST, containment update at 8:05 a.m. CST, and final all-clear at 10:27 a.m. CST when Northwestern Energy completed repairs",
    "The 8:05 a.m. CST containment update did not end the incident, the final resolution took an additional 2+ hours of utility work, illustrating the distinction between 'leak contained' and 'situation resolved'",
    "All three verbatim SDSU Campus Alert texts were recovered from The Collegian (SDSU student newspaper), which quoted each message in full with confirmed timestamps"
