An explosion relief system for a building having a wall includes an explosion relief panel substantially covering an opening in the wall and a blast shaft mounted adjacent to the explosion relief panel. The blast shaft includes a first opening and a second opening. The first opening is adapted to permit at least a portion of a force of an explosion to escape therefrom and the second opening allows rain, snow and the like to pass through the blast shaft when the explosion relief panel substantially covers the opening in the wall. The second opening is substantially covered when the explosion relief panel is forced away from the opening in the wall when the explosion occurs. A blast shaft substantially as described above and a building including the explosion relief system described above are also provided.
