March 14th in Halifax was the dropped container incident, I can't find the thread on glp I was thinking of:

Chronicle Herald, Mar. 14, 2014: Emergency crews were on high alert Thursday night as it was feared a container of nuclear material was leaking aboard a ship at Halifax’s north-end Ceres terminal. [...] “We have a leak, I’ve got to go,” Halifax Fire and Emergency Service Division Commander Corey Beals said [...] Later, the Halifax Fire Department confirmed that four cylinders containing uranium hexafluoride fell from a container, but there was no leak [...] There were also reports that the Halifax Harbour Master had been alerted that there was a ship in the harbour leaking radioactive material. [...] The wife of a worker at the Ceres terminal tweeted late Thursday night that her husband was on scene when the container fell and that he has been quarantined. [...] Uranium hexafluoride that contacts water or moisture in the air will decompose to form a cloud of toxic fumes. If a container carrying the chemical were to leak, it could prove fatal.
