DOWNLOAD PATTERN

This pattern was developed for two reasons:

  1. To argue compliance with the ALARP principle at the highest level when addressing system level hazards.
  2. To provide a more structured approach to presenting a ‘Hazard Avoidance’ argument (See Hazard Avoidance Pattern) by showing differing treatment of hazards according to their associated risk.
