Some sources may assert more than three step in risk assessment analysis, however, since all sources agree and accord with national standards of risk management, three central steps can be isolated.
The fist is hazard identification. Herein assessment is made by analyzing data collected from "toxicological and epidemiological" study reports.
The second is hazard evaluation and context analysis, for example, if a toxic spill has occurred or if airborne chemical weapons have been released, is there a dose-assessment response that is needed.
The third is examine core threat capabilities of threats or hazards and set capability targets, e.g., search or infrastructure protection.
