Manhole Explosions: Why They Occur

Manhole Explosions Part 1: Why They Occur

July 20, 2018

As cities grow due to rapid urbanization, manhole explosions are becoming a serious public hazard and a nightmare to utilities that maintain manhole infrastructures. Due to aging electrical cables and lack of insight on why these events occur, the potential for manhole explosions to injure and destroy property is steadily rising. This presentation identifies the fundamental causes of manhole fires and explosions in duct-manhole systems and sheds light on whether these events are fueled by electrical energy, chemical energy, or both. The presentation also dissects the complex interactions between the electrical cables and chemistry that happen inside the manhole infrastructure so that resources can be intelligently focused to prevent explosions from occurring.
