On the afternoon of March 28, 2016, [WTXL reported](https://www.wtxl.com/news/tallahassee-fire-department-responds-to-gas-leak-at-fsu/article_27cad656-f527-11e5-bf3b-0f68906f4a1d.html) that the Tallahassee Fire Department responded around 1 p.m. EDT after a 200-pound cylinder of ethylene gas was found slowly leaking. Hazmat crews secured the cylinder, occupants were temporarily evacuated, and they were let back in just after 3:15 p.m. EDT, with FSU posting updates on Twitter. FSU's emergency-management guidance directs occupants to evacuate and not investigate suspected gas leaks, the posture reflected here. The case adds a confirmed research-gas leak to the archive, distinct from the reported-odor evacuations that often turn up nothing.",
