Application of Qra in Operational Issues

This study has performed research into the use of risk in Health and Safety Executive's (HSE) operational decisions in the context of the COMAH regulation 4.

The research focused on the use of regulatory guidance, risk matrices and Quantitative Risk Analysis (QRA) to demonstrate compliance with the ALARP principle.

Each approach has its strengths and weaknesses, for any particular situation.

Cost Benefit Analysis (CBA) when used in conjunction with QRA is able to provide an economic justification as to whether risk reduction measures should be implemented.
