We Can See the Danger but the System Won’t Act

These ~10 problems invert what engineering students expect about safety: the sensor works, the danger is detected, the system doesn't act. A pipeline operator ignores a leak alarm after years of false positives. A hot bearing detector fires but no federal standard requires the train to stop. A breast implant adverse event is reported but no mechanism forces long-term follow-up. Green hydrogen is certified but no standard requires temporal matching. The failure isn't detection — it's the broken loop from signal to action.
