Fail-Safe Switch
When activated, a TARDIS will seek out and lock on to the nearest habitable environment. This step will be omitted if the TARDIS is already materialized in such a location. Once locked on, Failsafe prevents any dematerialization or materialization of a TARDIS until the switch is deactivated. Emergency doors will be generated in any areas of the TARDIS that (due to dimensional instabilities) have been cut off from the Main Doors in the Control Room. These doors will lead to the outside of a TARDIS and will appear integrated into the local environment. The existence of these doors will be unstable until the emergency bypass device is engaged.
Though it can be manually activated by the operator, the TARDIS will automatically initiate Fail-Safe if the TARDIS is about to break up (possibly due to a complete failure of the Main Space-Time Element while in the Vortex). Removing the Primary Refraction Tube prevents the Failsafe setting from being changed.
