    Outputs
      Main Description
      The hazard analysis is a key document that captures hazards, risks, faults, and control measures together. The control measures mitigate the risks and so must be captured as requirements on the system to manage the risks to an acceptable level.
      Steps
      Create initial hazard analysis
      The hazard analysis is a key document that captures hazards, risks, faults, and control measures together. The control measures mitigate the risks and so must be captured as requirements on the system to manage the risks to an acceptable level.
      Identify hazards
      Hazards are conditions to avoid. Hazards are analyzed using Fault Tree Analysis and/or Failure Means and Effect Analysis.
      Quantify risks
      Risk is the product of the severity of a hazard and its likelihood.
