A chemical plant opening a valve to prevent an explosion is an example of what kind of dependability/security issue?
Show answer Hide answer
Answer: D. Hazard detection and removal
Explanation
Hazard detection and removal involves identifying dangerous conditions and taking active steps to eliminate the hazard. Opening a safety valve actively relieves dangerous pressure before a catastrophic system failure occurs. This dependability mechanism recognizes abnormal operational states and intervenes to neutralize potential safety threats. Safety-critical systems incorporate automated monitoring mechanisms to detect anomalies and prevent physical disasters. Industrial chemical plants rely on pressure relief systems to maintain safe operating boundaries continuously. Dependability engineering focuses on ensuring systems operate reliably and safely under all expected conditions.
Nuclear reactors use automated control rods to detect overheating conditions and shut down safely. Aerospace control software monitors engine temperatures to prevent catastrophic structural component failures during flight. Manufacturing assembly lines employ emergency shutdown sensors to protect human workers from dangerous mechanical hazards. Hazard avoidance prevents dangerous conditions from ever arising through careful architectural design choices. Damage limitation minimizes the negative consequences after a failure or accident has already occurred. Hazard detection alone identifies dangerous conditions without automatically executing the active removal procedures.
