The detection of a dangerous fault shall result in either:
1. a specified action to achieve or maintain a safe state; or
2. the repair of the faulty system within the mean repair time (MRT). During this time the
continuing safety shall be ensured by additional measures and constraints. The safety
integrity provided by these measures and constraints shall be at least equal to the safety
integrity provided by the FDS in the absence of any faults.
