Sulfr hexafluoride and a world first

Specialist detection instrumentation in combination with an automated process control system is used to detect and pre-vent leakage that may result through either operator or plant fault. To ensure safety, all plant processes have been internalized to prevent human expo-sure and eliminate the chance of acciden-tal exposure to liquid nitrogen.
