One is, obviously, investigating the notified accidents—and, particularly, serious harm accidents and fatalities—when they receive those notifications. They have to be thoroughgoing investigations, they have to gather evidence, and they have to make a judgment call about whether a prosecution is warranted. And just in the way elsewhere in the justice system has to operate, they have to work out levels of fault and culpability and distinguish those things that are, largely, the product of accident or oversight, as opposed to recklessness and abject carelessness, which will attract, if not a prosecution, a severe penalty. The other function they have to do is to work with employers or businesses, and, indeed, whole industries—through their improvement notification sort of processes, through educated processes—to lift the level of health and safety performance. So they've got to be able to do both. It's not quite carrot and stick; it's sort of big stick and small stick, I suppose, that they have to use to make that change.
