- Description
- The incident occurred on two hydrogen compressor units installed on the roof of a four-story building.
The Great East Japan Earthquake caused the rupture of the flexible piping and the outlet piping of a compressing system consisting of two compressors. The leaked hydrogen ignited and exploded. The fire went out naturally without any firefighting efforts being made. There were no injuries.
The compressor was connected to a hydrogen storage system, but the quantity of hydrogen was limited because the earthquake activated also the seismic sensor of the system, which interrupted the hydrogen supply from the buffer tank. - Event Initiating system
