    - A hazard analysis is used as the first step in a process used to assess risk.

    - The identification of different type of hazards is the result of hazard analysis.

    - A potential condition and exists or not (probability is 1 or 0) is a hazard.

    - It may in single existence or in combination with other hazards (sometimes called events) and conditions become an actual Functional Failure or Accident (Mishap).

    - Scenario is the way which exactly happens in one particular sequence.

    - The scenario has a probability (between 1 and 0) of occurrence. A system has many potential failure scenarios.

    - A classification is assigned based on the worst case severity of the end condition.

    - Combination of probability and severity is risk. Preliminary risk levels can be provided in the hazard analysis.

    - The validation, more precise prediction (verification) and acceptance of risk is determined in the Risk assessment (analysis).

    - The main goal of both is to provide the best selection of means of controlling or eliminating the risk.

    - This term is used in several engineering specialities, including avionics, chemical process safety, safety engineering, reliability engineering and food safety.
