A safety-barrier is a physical or procedural control deliberately engineered into a system to prevent, mitigate, or detect hazards before they cause harm. Barriers are categorised by function: prevention barriers stop initiating events, mitigation barriers reduce consequence severity, and detection barriers provide early warning. They operate through engineered controls (physical guards, interlocks), administrative controls (procedures, permits), or personal protective equipment. Barriers persist through formal implementation in safety management systems, documented in hazard analyses and verified by inspection and testing.

Definition
Why it is in scope
Human-made physical or procedural controls designed to prevent, mitigate, or detect hazards before they cause harm. They form part of layered safety systems across industry, aviation, and healthcare.

Safety barriers are physical or procedural controls deliberately engineered into process safety systems (e.g. layers of protection in HAZOP/LOPA). Their designed purpose is to prevent, mitigate, or detect hazards within process-safety practice. Law 8d: servant (safety-barrier) points at master (process-safety).
- cms8zrlnh02qk73fknpw19lyiSERVES →
Safety barrier is a physical or administrative control designed for the sake of hazard mitigation — it creates separation between hazards and people. Its designed purpose (Law 8d) is to further hazard mitigation: servant (safety-barrier) → master (hazard-mitigation).
- cms9293jz002i7skq3m4d9hr1SERVES →
Safety barriers (engineered and organizational) exist specifically to support safety-management's operation. Per Law 8d: the designed purpose of barriers is to further safety-management's goal of preventing harm. The test: remove safety-management as an organizing practice, and barriers lose their coordinated deployment — they become ad hoc rather than systematic layers.
