Which safety certification level is required for the KAVACH system?
- A.Safety Integrity Level-2
- B.Safety Integrity Level-3
- C.Safety Integrity Level-4
- D.Safety Integrity Level-5
Correct answer
Explanation
The correct answer is Safety Integrity Level-4, usually written SIL-4. The release describes the train protection system as heavily dependent on technology and therefore obliged to carry safety certification of the highest order, which it identifies as SIL-4. Level-2 is wrong because it is a lower grade and would not satisfy a system that can apply brakes on a running train without human action. Level-3 is wrong for the same reason; it is one step below the grade actually named. Level-5 is wrong because the release names Level-4 as the highest order of certification here, so a fifth level is not what the system is held to. In examinations this fact is often paired with the system's purpose, so remember together that KAVACH is an indigenous Automatic Train Protection system, that it guards against Signal Passing at Danger, and that it is certified at SIL-4.
