If an HVL/cc switch lost all of the SF6 gas, would there be any electrical risk?

No. The HVL/cc switch with no SF6 gas still can withstand full BIL and 1 minute withstands.

Note: The switch cannot interrupt load current without the gas.

The switch was tested for a full 100 full load interruptions with the SF6 gas at 0 psig for the IEC market.
