05:22 Pressures on Argon, Ethane and C02 low
Low pressure Alarm on. Rebooted Gas shed IOC
Checked the shed all bottles seem to have pressure except for Nitrogen.
06:00 paged Jack Seagal. NItrogen controls valves, and thus pressure
should not be zero.
06:30 Problem was fixed by Jack and the pressures of the gas shed
are; Argon: 1816psi
Ethane:313.7 psi
C02: 471 psi
