Step 1 - Preliminary System Definition |
Activity: Preliminary System Definition: Agree station systems what is being changed and scope of change; Agree operational changes; agree any organisational change. Conduct preliminary risk assessment to determine the systems that affect safety and record the decision making process. Purpose: To determine the significance of a change, you first have to define and agree the system then assess if the system affects safety. |
|
|
CSM-REA Stages |
1. Preliminary System Definition 2. Determine the significance of change. 3. System definition 4. Hazard identification 5. Apply Risk Acceptance principles. (Standards; similar in service; Explicit Risk Estimation). 6. Evidence conformance to the Risk acceptance principles. STEP 6 IS THE END OF THE DESIGN STAGE. |
|
|
Step 2 - Determine the significance of change. |
Activity: Where a change has an impact on safety, the significance of the change is assessed and recorded against: The failure consequences; Novelty; Complexity; Monitoring; Reversibility; Additionally. Purpose: This allows prioritisation of the most important systems to analyse. |
|
|
Step 3 - System Definition |
Activity: For systems that affect safety and are significantly changed, define - the purpose and functionality of the system; the system boundary and interacting systems; physical and functional interface (including people) and existing safety measures that apply to it. Purpose: Provides key information on the systems that are being changed. |
|
|
Step 4 - Hazard identification |
Activity: A structured group discussion with competent attendees will use a framework and template to systematically identify and record the hazards for each system. Purpose: To identify all foreseeable hazards which are then analyses in the next steps. |
|
|
Step 5 - Apply Risk Acceptance Principles |
For all of the hazards that have been identified, each shall be analysed and mitigated by either - Applying standards; Comparison with similar systems in service; Explicit Risk Estimation. Record the |
