CLASSE Safety Handbook

L0 Vent

There is a vent system in the L0 experimental hall that can quickly exhaust any contaminated air outside the building. The L0 Vent buttons are located on the CHESS control panel, the West Flare, and the CESR Control Room. If you know of a leak of toxic or explosive gas, or suspect a large venting of cryogenic liquids in the Wilson Lab experimental areas, inform a CHESS operator or CESR Operator immediately, who will activate the L0 venting system. The operator will likely request evacuation of all personnel from the affected areas.
