The document discusses Dalhousie University's use of social media for emergency communications. It outlines three emergencies - an asbestos discovery forcing an evacuation, a fire at the Life Sciences Centre, and Hurricane Earl. In each case, Dalhousie was able to provide timely updates on Facebook, Twitter, and its website to inform students and the community. The integration of a new media officer improved Dalhousie's social media response and increased its online presence. Lessons from managing communications across these emergencies will help Dalhousie improve future social media strategies.
