[The Utah Statesman reported](https://usustatesman.com/gas-leak-in-the-utah-state-university-life-science-building-prompts-evacuations/) the leak was caused when an excavator installing a tree in front of the Life Sciences building punctured a natural gas line. The all-clear message contained two typos ('an' for 'and' and 'Clases' for 'Classes'), providing yet another data point for the pattern of errors-under-pressure that recurs across campus alert communications.",

  "context": "The [Utah State](https://en.wikipedia.org/wiki/Utah_State_University) gas leak is a minor incident that nonetheless contributes an important data point to the corpus. The two typos in the all-clear ('an open' for 'and open' and 'Clases' for 'Classes') are consistent with the broader pattern documented across institutions: alert composition under time pressure produces characteristic errors that serve as markers of authenticity. A natural gas leak [outside the Life Sciences building on USU's Logan campus](https://www.fox13now.com/2019/04/01/three-buildings-evacuated-due-to-gas-leak-at-utah-state-university) was first reported around 11:45 AM MDT on April 1, 2019, after [an excavator installing a tree in front of the building punctured a buried gas line](https://usustatesman.com/gas-leak-in-the-utah-state-university-life-science-building-prompts-evacuations/). The University Inn, Life Sciences building, and a third adjacent building (variously reported as the Biotech building or the [Biology and Natural Resources building](https://qanr.usu.edu/facilities/biology-natural-resources)) were briefly evacuated. The incident was resolved without injury, and classes resumed the same day.",
