Schematic drawing of the high-pressure gas supply system. Gas detectors for CO and H2 are installed in both cabinets and the experimental hutch. The installation height for the CO detector in the hatch is roughly 1.5 m. The H2 detector in the hutch is installed on the ceiling. If a leakage is detected, the control panel will shut down the solenoid valves automatically and increase the speed of the fan to full speed which, under normal operation, runs at half of its maximum speed. |
