Campus emergency responders gathered for Harmony 10, Western’s annual emergency exercise, in response to a simulated explosion at Western’s North Substation last Thursday morning. Campus responders involved in the exercise included Campus Community Police Service; Student Emergency Response Team (SERT); Fire Safety and Emergency Management; HazMat Team; Emergency Response Team (ERT); and Emergency Operations Control Group (EOCG). In addition to testing on-site readiness, the exercise included tests of the university’s communication tools, including mass email, homepage, as well as emergency-related messaging on social media and the main telephone switchboard.
