formal risk assessments
KPN Risk Analysis – this analysis focusses on the risk associated with the climbing infrastructure proposed for the Kangaroo Point North climbing development in Brisbane.

This formalism allows a relationship to be drawn between bolt specification, and the rate of materialisation of severe injury from bolt failure.
