safetyadequate

safetyadequate is a term used in risk management and safety engineering to describe a level of safety that meets the minimum requirements of applicable standards and is sufficient to keep risks within defined, acceptable bounds for a particular context. It signals adequacy without asserting excellence and can be context-dependent, varying with hazard, activity, and stakeholder risk appetite.

In practice, describing a system as safetyadequate means that identified hazards have been mitigated to a point where the residual risk falls below an acceptance threshold specified by regulations, codes, or internal policies. The designation may accompany a formal safety case, hazard analysis, or compliance assessment. It does not necessarily imply that no improvements are possible or desirable; additional controls or design changes could raise the safety level, but would not be required to meet the baseline criteria.

Determination of safetyadequacy typically involves hazard identification, risk estimation, evaluation of controls, and verification against acceptance criteria or standards. Tools such as risk matrices, fault tree analysis, or quantitative risk assessment may be used. The concept is related to, but distinct from, ALARP or as low as reasonably practicable, and from simple regulatory compliance; safetyadequate focuses on meeting defined acceptability rather than optimizing risk reduction.

Criticism centers on subjectivity and variability in risk acceptance criteria, which can lead to inconsistent judgments about adequacy across organizations or jurisdictions. Proponents argue it provides a practical baseline for safety while avoiding over-engineering; critics worry that declaring safety adequate may foster complacency or underinvestment in safety culture.
