Industries in the UK to identify hazards in chemical plants in the 1960s (CIA, 1997). HAZOP analysis assumes that hazards arise in a process plant due to deviations from design intents or from acceptable normal behavior. In the HAZOP study, PIDs are systematically examined by a group of experts (HAZOP team). The
