TBM has technical interfaces to areas requiring special protection, such as safety instrumented systems (SIS), security services, and fire alarm systems. If these interfaces are compromised intentionally or unintentionally due to errors in TBM, this can result in legal violations and dangers to life and limb.

For example, if a visual or audible warning is overridden in the event of a fire alarm in a data centre, people in the room will not be able to leave before the room is flooded with extinguishing gas. Similarly, a false fire alarm can lead to escape doors being opened (allowing unauthorised access) or doors being closed (which may trap people inside).
