Red alerts are critical alerts in which immediate reaction is mandatory!

In our building the following red alerts may occur:

• Fire alarm. Signal: A loud sirene throughout the building. Reason: Fire detected automatically by smoke or temperature or manual alarm. Measure: Leave the building immediately through the next exit (either the stairs on the front side or the back side) and gather at the meeting point at the front side of the building to be counted.

• Machine cooling. Signal: Alarm light and beeper on the wall opposite the electric workshop. Reason: Pumps of internal machine cooling in the roof cabin are down, no cooling water flow in the MCh labs. Measure: First call security officer, then inform persons responsible for (sensible) machines (APT/FIB, JAMP, Kybele, Jarvis first). In case of absence of all security officers follow instructions on the wall next to alarm.

• Air liquidification alarm. Signal: Sirene and sign “Gasalarm” in the basement outside the air liquidification room. Reason: Low oxygen content detected in air liquidification room, presumably due to defect in liquification machine or storage containers. Measure: Leave the floor and call security officer immediately. Risk of low oxygen content in air.

Yellow alerts are indicating technical alarms which require rapid but not immediate reaction. The following yellow alarms may occur:

• Technical gas alarm. Signal: Orange blinking light on analytics lab floor ceiling. Reason: One or more bottles of central technical gas supply (Ar, N2, O2, H2) empty. Measure: Exchange empty gas bottle in the gas storage area behind the building with a full one. Inform responsible person (Dr. Mraz).

• Central cooling water alarm. Signal: LED sign “Kühlwasser” in PVD labs is on. Reason: The central closed loop cooling water, supply for the whole building, backening the machine cooling, is off. Measure: Call security officer.
