Campus Center, Dean Hall, Miller Hall and Building 37 were cleared, and the campus used the UH Alert notification system to push updates. UH Mānoa's [official Facebook UH Alert post](https://www.facebook.com/uhmanoa/posts/uh-alert-the-gas-leak-has-been-plugged-but-evacuation-of-the-areas-cited-below-i/10151282639524001/) captured the careful sequencing of the response: it announced that the leak had been plugged while stressing that the evacuation remained in effect 'until the all clear is given.' The leak was secured roughly an hour after the evacuation began and students were allowed back inside, with no injuries reported. The case is an example of a hazardous-materials emergency notification that separated 'the hazard is fixed' from 'it is safe to return.'",
