layers-of-protection is the safety engineering concept of deploying multiple independent protective barriers in sequence between a hazard and its target. Its parameters are: (1) each barrier must be independent — no single cause can defeat all layers; (2) each barrier must be capable of preventing or mitigating the hazard on its own; (3) barriers are arranged so that failure of any single layer does not cascade. Its persistence mechanism is engineering design standards and systematic safety analysis. [formal: multi-lamina-protectio | substrate: behavior | horizon: a life | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A human-made safety engineering concept that uses multiple independent protective barriers layered in sequence to prevent a hazard from reaching its target. Each layer operates independently; failure of one layer leaves the remaining layers to provide protection. Built to persist through engineering standards and design practice.

Layers of protection is a safety engineering approach built and maintained for the sake of safety-management: multiple independent protective barriers are organized and deployed to manage process safety risk. The method serves safety-management by providing a structured framework for barrier management.
