On May 4, 2013, a freight train derailed in Wetteren, causing a hazardous release of toxic substances, including acrylonitrile and butadiene. This incident prompted immediate intervention by emergency services, coordinated at municipal, provincial, and federal levels. Key actions included containment of hazardous materials, evacuation of local residents, and continuous monitoring of air and water quality. The Flemish Ministry of Environment, Nature and Energy played a crucial role in crisis management and environmental protection. The incident highlights the importance of preparedness and response strategies in safeguarding public health and the environment.
