Opening of 132kV Breaker with Very Low sf 6 Pressure - CR4

"LOCK-OUT of 132kV transmission line circuit breaker in CLOSE position due to VERY LOW Sulfr hexafluoride PRESSURE". CB is dead-tank, outdoor type (not GIS). At first thinking, it seems possible to open the breaker with very low or zero Sulfr hexafluoride pressure, after it is completely isolated from the line and busbar sides, and grounding also provided at both ends
