According to some embodiments, such process may be cooperative, so that the process must be completed by more than one user of the systems, methods and processes. According to some embodiments, in the wake of a user concluding the process, the systems, methods and apparatuses cooperate to inform a user of whether or not a system being serviced by the user has changed its safety state in the wake of the user having completed the aforementioned process.
