Emergency service workers from across Durham Region conducted an exercise Friday, to make sure they’re prepared in the event of a disaster. The specific situation being practiced was a problem with distributing natural gas in the area. Commissioner of Planning and Economic Development, Alex Georgieff says coordination between responders is vital. Director of Emergency Management, Ivan Ciuciura says in a disaster, residents also need to be self-sufficient for up to three days. Fortunately because of where Durham’s located, weather-related catastrophes aren’t likely but Ciuciura says things like train derailments and gas disruptions certainly can occur.
