A common cause failure (CCF) is a failure where:

  • The function of multiple CI is disrupted or destroyed by the same cause or hazard affecting the CI at the same location or area in the same time frame (e.g., a hurricane blocking roads and affecting telecommunication and power lines; a collapsed bridge which blocks inland shipping, road transport and caused disruption of gas, power and telecommunication lines)
  • Item failures result from a single shared cause and coupling factor (or mechanism)
