Guideline summary

  Hazards can be detected by checking the system compliance with the operational rules.

  Hazard detection is based on two types of detectors

Component-level detectors

Component-level detectors are based on sensors and indicators

System-level detectors

System-level detectors are special units added to detect exceptional scenarios, situations and events.

  General requirements

• Specifications: make sure that specification documents include specifications of all the situation, and of their expected combinations, comprising the design scope.
• Testability: design probes to bypass the sensors and to fake measurements used for the testing
• Mode verification: test the exceptional situations of the primary and control modes
