This checklist covers all phases of the safety lifecycle, including concept definition, overall scope definition, hazard and risk analysis, safety requirements specification, realization, installation, operation and maintenance, modification, and decommissioning.
It provides a structured framework for continuously assessing and improving safety processes throughout the entire lifecycle of safety-related systems, ensuring that safety considerations are maintained from initial concept to final decommissioning.
This checklist should involve a cross-functional team including safety managers, project managers, engineers, operators, and maintenance personnel responsible for different aspects of the safety lifecycle in energy and utilities organizations.
Key elements include safety planning, risk assessment methodologies, safety requirement allocation, verification and validation processes, change management procedures, and safety performance monitoring.
A comprehensive audit should be conducted annually, with additional reviews performed at key transition points between lifecycle phases or when significant changes are made to the safety-related system or its operating environment.
