| 2.3.1-4-1 Ensure system safety integration with design engineering |
Phase A |
Phase B |
Phase C |
|
Ensure hazards associate with the proposed design or function are evaluated for hazard severity, probability, and operational constraint. Ensure safety provisions and alternatives needed to eliminate hazards or reduce associated risk to acceptable risk are incorporated. Evaluate safety related interfaces consideration among various elements of the system to include software related controls.

| 2.3.1-4-2 Ensure operating & support hazard analysis assessed for adequacy and completeness |
Phase A |
Phase B |
Phase C |
Phase D1 |
Phase D2 |
Phase D3 |
|
The operations and support phase is the final phase and extends throughout the useful life of the system ending with disposal of the system. Ensure monitoring of the system throughout the life cycle to determine adequacy of the design, and operation, maintenance and emergency procedures to include safety review of proposed new procedures or changes to ensure procedures, warnings, and cautions are adequate and inherent safety is not degraded.

| 2.3.1-4-3 Ensure health hazard assessment process is evaluated for adequacy and completeness |
Phase A |
Phase B |
Phase C |
|
Ensure a documented health hazard assessment identifies health hazards, evaluates proposed hazardous materials, and proposed protective measures to reduce the associated risk to an acceptable level.

| 2.3.1-4-4 Ensure architecture and design support detection, diagnosis and recovery from any safety-impacting hazards that need to be mitigated per requirements |
Phase B |
Phase C |
|
Review architecture to ensure that fault containment or detection and recovery features are identified. Review design documentation to ensure that these architectural features are carried through. May be automated features or recoveries carried out by humans. Ensure that any unmitigated single point failures are appropriately justified.
