Guidance Note TitleRisk Assessment
Principal AudienceThis guidance note forms part of a suite of four guidance notes which are designed to help operators through the process of conducting a formal safety assessment in support of the evidence that risks are reduced to a level that is ALARP.

This suite comprises the following documents:
  • Hazard Identification

  • Risk Assessment
  • ALARP
Core Concepts

  • The likelihood of potential major incidents being realized
  • Qualitative & quantitative assessment techniques
  • Uncertainties, assumptions and sensitivities
  • Clear linkages between hazards, major incidents, control measures and the associated consequence and risk
  • A prioritized list of actions to reduce the risks to ALARP, if required
