c) Using the risk matrix given in Figure 2, complete a hazard log by proposing one safety risk related to the interface between signalling system and rolling-stock. The hazard log should contain the following columns: 1. Hazard Description 2. Cause 3. Consequence 4. Initial Frequency 5. Initial Severity 6. Initial Risk Rating 7. Safeguard 8. Residual Frequency 9. Residual Severity 10. Residual Risk Rating (9 marks) RI A (Frequent) B (Probable) C(Occasional) D (Remote) E (Improbable) F (Incredible) Frequency Severity 3 2 (Marginal) (Critical) Injury Fatality <5 RI R2 R1 R2 R2 R3 R2 R4 R3 R4 R4 (Insignificant) Service Delay R2 R3 R3 R4 R4 R4 (Catastrophic) Fatality >= 5 R1 R1 R1 R2 R3 R4 Figure 2 d) Explain the weakness of the risk matrix in Figure 2 (2 marks), and propose a solution to the problem with an example (3 marks).
