Which phase of the safety lifecycle includes operation and maintenance?

• A. Decommissioning
• B. Operation phase
• C. Modification
• D. Planning

Answer: (B)

The operation phase is integral to the safety lifecycle as it encompasses the ongoing activities that ensure a system operates safely during its intended life. This phase includes regular monitoring and maintenance of the system to confirm it continues to function as designed and meets safety requirements. Operational activities may involve routine checks, updates, adjustments, and any necessary repairs to sustain safety performance. In contrast, the other phases focus on different lifecycle stages. Decommissioning pertains to the shutdown and dismantling of a system once it reaches the end of its effective life. The modification phase involves making changes or improvements to an existing system, which can temporarily alter its safety characteristics until those changes are fully integrated. Planning is associated with the design and preparation stages before the system is operational, setting safety requirements and strategies. Overall, the operation phase is vital for maintaining safety during the active use of the system, making it the correct choice for this question.
