Which standards include the concept of the Safety Lifecycle?

• A. FM7605 only
• B. ISA 84.01 and IEC 61508 only
• C. Only IEC 61508
• D. All of the above

Answer: (D)

The concept of the Safety Lifecycle is vital in ensuring that safety-related systems are developed, implemented, maintained, and decommissioned systematically and effectively. Each standard mentioned has its own approach to this concept. IEC 61508, for instance, is a key international standard that provides a framework for functional safety of electrical, electronic, and programmable electronic safety-related systems. It explicitly defines the Safety Lifecycle, detailing phases from concept through to decommissioning, and outlines the necessary activities and assessments at each stage to ensure safety. ISA 84.01, which is aligned with IEC 61508, particularly focuses on process safety in the automation industry. It adopts the Safety Lifecycle model, addressing aspects such as risk assessment and management, and thus ensures safety throughout the operational existence of safety systems. FM7605 is another standard that, while perhaps less commonly referenced than the previous two, also engages with the Safety Lifecycle concept within the context of fire and gas detection systems, showcasing the importance of a lifecycle approach in various safety applications. Collectively, these standards illustrate the broad adoption of the Safety Lifecycle concept across different domains, confirming that the correct answer encompasses all the mentioned standards. This indicates a unified understanding across industries of the necessity to manage safety systematically throughout a system’s
