This checklist covers hardware architecture design, component selection and qualification, failure mode analysis, diagnostic techniques, and hardware integration with other system elements.
It provides a structured approach to verify that hardware safety requirements are properly implemented, tested, and maintained, reducing the risk of hardware-related safety failures in critical systems.
This checklist should be used by hardware engineers, safety engineers, quality assurance specialists, and auditors involved in the design, implementation, and assessment of safety-critical hardware in the energy and utilities sector.
Key elements include hardware architecture design, component reliability data, failure mode and effects analysis (FMEA), diagnostic coverage assessment, and hardware-software integration.
Assessments should be conducted during the initial design phase, before major hardware changes, and periodically (typically annually) to ensure ongoing compliance and safety integrity.
