Evaluate the performance of safety barriers
Hazard analysis: Summarizing risks

In order to prevent, detect and protect against major and dreaded events (EM and ER), safety functions are required. For example, the safety functions "detect fire" and "control fire" are associated with the major event "widespread fire".

Safety targets are associated with each safety function, and these can be quantified, for example, by an implementation time, or thresholds (pressure, temperature, etc.), which must not be exceeded.
