A safety case is a document developed for a facility which:

  • Outlines the Hazard Identification and Management functions required by the Safety Management System (SMS);
  • Describes the Safety Management System in place to ensure the controls are effectively applied and consistently managed throughout the life cycle.
  • Outlines the Safety requirements to ensure that Risks to personnel , the facility and the environment are eliminated SFARP, or if this is not practicable are minimised SFARP.
  • Describes how the risks are controlled/mitigated by the application of Hierarchy of Controls. The safety requirements ( controls and mitigations) derived from Hazard Analysis in turn become a subset of system requirements.


  • The formal safety assessment identifies the safety critical aspects of the facility from both a technical and management perspective.
  • Ensures that all risks that have been identified on a facility are eliminated or minimized SFARP.
  • The appropriate Performance Standards are defined for the operation of the safety critical aspects of the facility. 


  • Identifies the Hazards, the cause or source of the Hazard, the Risks and Consequences  associated with the Hazard and Control Measures in place/required to eliminate or minimize Hazard Risks SFARP. The outcome of the assessment is the mitigated Likelihood and Consequence of the Hazard which is expressed as a band within  a Hazard Risk Index (HRI) i.e Very Low, Low, Medium, High to Very High with a SFARP determination.


The Safety Case identifies the methods to be adopted for monitoring and reviewing all activities associated with operation of the facility with a view to continual improvement in HSE performance.

Safety Case Overview


Review of a Safety Case broadly entails:

  • Introduction – The Company (Operator), the facility and scope of operations, management and operations, objectives of the HSE case, demonstration of  SFARP and supporting documents and appendices.
  • HSEMS– The Health Safety and Environment Management System and Risk Management philosophies.
  • Facility Description – Design, structure and layout, Equipment and Systems utilised for operations, Escape and evacuation, Inspection repair and Maintenance and Hazardous Substances and Inventories.
  • Formal Safety Assessment– Hazard identification and Risk assessment, MAE’s, Fire and explosion analysis (FEA) , Escape evacuation and rescue assessment (EERA), SCE assessment and demonstration of SFARP.
  • Performance Standards (PS)– A statement of the performance required of a system or item of equipment, person or procedure, to eliminate or minimize the safety risk SFARP  throughout the life cycle of the installation. PS are generally in accordance with Classification requirements, industry standard specifications and codes of practice; plus any additional requirements specified in the Safety Case.
