This afternoon, the sappers of the Landon rescue Center help a 26 years old worker partially buried in a sand silo. Just moments ago, the man walks on the top of the silo when the sand shifts beneath his feet. His head only is out from the sand. One of his colleagues calls for help. When they arrived, the battalion chief makes establish a security perimeter. He asks for the Research and Rescue in Urban Zone Group, in order to secure the worker while the silo is empty.
