Time to abandon the risk matrix? @MattD2
Personally I agree with you.
I don't like Risk Matrices - numerical, alphabetical or traffic light style - to set the outcome of hazard. gave them up a few years ago.
I think the OHS profession here has got hung up on justifying positions rather than providing value. Also that business management has driven changes to suit themselves while not engaging with workers.
As an aside, the earliest reference in NZ I can find to using risk matrices is in SiteSafe's 2016 SSSP when initial and residual risk rating appeared in the task analysis. That the release of this version matches closely with the implementation of HSWA is, for me, more than a coincidence.
For me the consequence of an activity is not if it will happen, but when it will happen. And the consequences I worry about are death (HSWA S25) or a notifiable injury or illness (HSWA S23). So for me, I look at the activity, identify the hazard(s), determine the consequence(s) and work through the hierarchy of controls.
I don't consider the likelihood. Progress down the HoC automatically takes care of that. Once the controls for each level have been identified, it's up to the officers and workers of the PCBU to choose and find their own balance. There's only so much money in the kitty and so much time to get the job done.
There's more, but probably better for a new post.
PS - who says the legislation is perfect?
