The pressure equalization door would have to be opened first to allow excess airpressure to escape or enter. If there was any diffence in barometric pressure between the vault and the outer air the vault door would be unable to open due to the pressure.

The corridor around the gold vault has a miror at every corner. A guard can see any persons or objects in the corridor from any one point. The purpose of this corridor is to detect any tunnelling activity before the vault walls could be breached.
