Well, about as much faith as I have that an open license is a certification that someone is not a complete nut behind the wheel. Oh wait a minute.......
You should probably PM me the name of the site you speak of. Either (a) I've been to it, and/or (b) I'll be having a stern word about it to our mining health & safety research centre!
Not that it matters a whole lot. The odd thing about the mining industry is that you can do everything possible except put people in a cage so that they are aware not to hurt or maim themselves. But if they do and even if you can prove it's their fault, you're still screwed.
That's probably one of the only industries where such is the case. Perhaps the only other ones are the other extractive industries (oil & gas), and chemical industries.
In theory, the workplace is safer with these new kinds of procedures. Sure, we still kill people every year and that's nothing at all to be proud of. But it's better than it was several decades ago when the death toll was orders of magnitude higher.
For my own sake I'd rather have the stupid induction and test than none at all.
