Safety Case
Developed
Presented to Regulator
License to Operate
Safety Assessment in accordance wth Work Health and Safety Regulation 2011 - REG 555
Hazard and Major Incident Identification in accordance with Work Health and Safety Regulation 2017 - REG 554
Across Operating Mode Variations

Commissioning
Varying capacities
Seasons
Must have consideration to relevant authority assessment recommendations
Emergency Services Organisations
Government Department or Agency with Regulatory Role
Documentation
Hazards and Major Incidents
Criteria and Methods used in Identification
Any external conditions which may give rise to the major incidents
Consideration of Risks both Individually and Cumulatively
Appropriate Worker Participation
Risk Assessment
Likelihood Estimation of each Major incident hazard
Potential Magnitude and Health and Safety Consequence
Risk Analysis
Risk Control - Safety Case must demonstrate that the implemented control measures are adequate to control risks associated with possible major incidents (NT Worksafe, 2012)
Existing Risk Control Identification
Identify additional control measures
Select control measures to be adopted
Justification for accepting or rejecting identified controls
e.g. Cost/Benefit Analysis
Investigate and evaluate failure modes
and rates for controls.
Evaluate Residual Risk
Compare Residual Risk Against Criteria
Maintenance and Monitoring of control measures
Risk Evaluation, and Relevant examples given for incidents with greatest consequence
How the control measures will adequately control the risks that could lead to major incidents
The range of control measures considered
Use of appropriate risk criteria used to create hierarchy of control measures
How each control measure will effect the risk level
Reasons for selection or rejection of particular control measures
Performance Indicators for selected control measures
Safety Information/Safety Management System (SMS) for Safe operation in accordance with Work Health and Safety Regulation 2017 - SCHEDULE 17
Emergency Plan
How it will limit the consequences of a major incident
