Primes¶
- Time-Of-Check To Time-Of-Use Flaw
- In industrial safety a lockout-tagout verification confirms a system de-energized, and energization occurs before the worker reaches inside; a confined-space atmospheric test taken at entry degrades over the hour spent inside.
This sourceMandates de-energization verification (zero-energy check) before servicing where unexpected re-energization could injure workers.

Mechanisms¶
- Safety Boundary Lockout
- This is the logic of lockout/tagout and safety interlocks, which isolate a hazard by default rather than trusting a human to choose safety under pressure.
This sourceRequires physical isolation and lockout or tagout of hazardous-energy sources to prevent re-energization during servicing.
