The public health response during and after the Lac-Mégantic train derailment tragedy: a case study.

Abstract

On July 6^th 2013, a train derailment occurred in the small town of Lac-Mégantic, Quebec, Canada, causing a major human and environmental disaster. In this case study, we comprehensively describe and analyze actions taken by the Public Health Department of the Eastern Townships, in close collaboration with community-based organizations, during both the impact phase emergency response and the post-impact recovery operations that continued for months. Due to the complexity of the event, public health actions needed to be broadly diversified. Preventive measures targeted chemical, physical, biological, and psychosocial hazards in the short-, medium- and long-term. Our analyses yielded valuable lessons that will improve and inform our response to future events while serving as a basis for developing a conceptual framework for public health emergency preparedness.
