safety-engineering

Safety engineering relies on safety analysis as its core methodology — remove structured hazard identification and risk evaluation and the discipline loses its systematic operation. Direction: safety-engineering (the practice) needs safety-analysis (the methodology) to function.

Safety engineering is built and maintained for the sake of risk management: it provides the systematic methodology (hazard identification, risk evaluation, control selection) that risk management processes depend on to make informed decisions. Per Law 8d, the servant (safety engineering) points to the master (risk management).

Safety engineering is a specific branch of engineering focused on identifying and mitigating risks across systems and products. A competent speaker would call safety engineering 'a kind of engineering.' Nearest kind: no intermediate category (e.g. engineering-discipline) exists between them, making engineering the nearest accepted kind.

Functional-safety is a specific kind of safety-engineering focused on achieving and maintaining safe state through systematic analysis of hazards and potential failures. Per Law 9: a competent speaker calls functional-safety 'a safety-engineering discipline'.

Fail-safe is designed and maintained for the sake of safety-engineering: it is the design approach ensuring systems default to a safe state upon failure, which is a core objective of safety engineering. Law 8d: for whose sake? The fail-safe principle serves safety engineering's goal of preventing catastrophic failure.

Safety-interlock as a design practice was derived from safety-engineering: engineers developed interlock mechanisms as part of the engineering discipline to prevent unsafe operations. Which-came-first: safety-engineering as a discipline predates specific interlock implementations.

failure-modes (the taxonomy of failure ways) is designed and maintained for the sake of safety engineering — providing structured vocabulary that enables systematic risk assessment, FMEA, and resilience planning. Law 8d: for whose sake? failure-modes → safety-engineering.

Alignment is built and maintained for the sake of safety-engineering — its designed purpose is to ensure AI systems operate within safe, intended behavioral boundaries. Safety engineering defines the parameters that alignment seeks to satisfy. Per Law 8d: the servant (alignment) points at the master (safety-engineering).
