Operational Risk Assessment

What is it?

The effective management of major accident hazards is an integral feature of safe operations on hazardous industry facilities. The WorkSafeⓇ Operational Risk Assessment (ORA) module ensures that robust arrangements are in place to identify and evaluate Major Accident Hazards (MAH), and to specify measures taken to ensure that major accident risks are controlled to ensure compliance with the relevant statutory provisions and to a level that is As Low As Reasonably Practicable (ALARP).

Operational Risk Assessment


Operational Risk Assessment (ORA) is a module for the management and control of abnormal operating conditions. The ORA module utilises innovative Risk Assessment techniques for evaluating and mitigating the risk of continuing to operate under abnormal operating conditions.

Benefit:  It allows the operator to determine whether it is safe to operate when an abnormal operating condition occurs.



WorkSafe® ORA allows the identification of:

  • what the normal operating conditions or case is
  • what the existing abnormal operating condition is or that which may result from the operational change to be performed
  • the mitigated case, its control measures and monitoring requirements

Benefit: It allows leadership to assess the risk and identify mitigation control measures that act as a bridge until the abnormal operating condition is removed (by isolating or shutting down the equipment, plant or if necessary the site), resolved or repaired, or approved as part of a permanent design change.



The WorkSafe® ORA process meets all regulatory authority requirements.

Benefit: It provides the operator with assurance that the system is robust and in line with the latest industry regulations.



WorkSafe® ORA used in conjunction with other WorkSafe® modules allows our clients to monitor site-wide Cumulative Risk.

Benefit: It is integrated with other key WorkSafe® Control of Work modules and therefore allows for more informed decision-making, as site leadership have full visibility of the actual residual risk if continuing to operate under the abnormal operating condition.
