The activity of identifying hazards for safety analysis and assurance — techniques (HAZOP, FMEA, STPA, hazard lists) and the completeness of the resulting hazard sets. Covers claims about whether identification methods miss hazards and how such gaps affect downstream safety arguments; excludes quantified risk-estimation claims (see Probabilistic risk assessment).

Major safety assurance failures often involve hazards that were identified but inadequately assessed or controlled

Accident investigations frequently find hazards that prior hazard analyses failed to identify

Incomplete hazard identification is a principal cause of safety assurance failures

The Nimrod Review found the Nimrod safety case was a paperwork exercise that missed key dangers
