What is the main difference in what a HAZID looks for compared to what a HAZOP looks for when checking how a process works?

The main difference in what a HAZID looks for compared to what a HAZOP looks for when checking how a process works lies in their primary focus and the depth of their investigation. A HAZID, which stands for Hazard Identification, primarily looks for *what hazards existwithin a process, facility, or system.
