Which of the following items is part of the concept stage safety tasks?

The correct choice pertains to the initial phase of a system's lifecycle, where identifying potential hazards is crucial for ensuring safety. Conducting an initial hazard analysis is integral to the concept stage as it involves systematically identifying, evaluating, and documenting potential hazards that might arise during the system's operation or development. This proactive approach allows for the early recognition of risks, which can then be addressed early in the design process, helping to inform subsequent design decisions and safety measures.

In contrast, other options focus on different stages or processes within the safety management framework. For example, a system safety assessment takes place later in the lifecycle, potentially after design and development when the system is more fully realized. This assessment evaluates how well the identified hazards have been mitigated and the effectiveness of safety strategies.

Updated hazard analysis is conducted as the design evolves, ensuring that new risks introduced through changes are accounted for. This step generally occurs beyond the concept phase.

Risk management plans encompass a broader scope that includes risk identification, assessment, and mitigation strategies throughout the project's lifecycle, not limited to the initial concept stage. Thus, while all the options are related to system safety in different capacities, the initial hazard analysis remains a foundational task specific to the concept phase.
