The central gas supply for the MCh labs is located outside at the rear parking lot, next to the garbage space. Five high-purity are gases available:
Currently both nitrogen tubes are supplied with 5.0 quality.
For safety reasons, the inflammable gases (hydrogen and oxygen) are cut off upon fire alarm or a general power failure. The switch to block/unblock these gases is located in the fire alarm system room on the 2nd floor in the rear stairway, on the left behind the door. Just turn the switch key to block/unblock the security valve.
