Owen,
In regards to the Reason model, if you use it to identify the cause of an accident you can take those lessons or causes and apply them to future activities to prevent a repeat. So the Reason model can act as a method of prevention. Anyway, I'm not in the business of teaching, discussing, arguing or bantering with you publicly. It has the potential to be fun, but the lesson would be painful for you....perhaps someone else would enjoy a robust joust with you?
Anyway, you go back to 4 Corners and come up with your own conclusion. Obviously the 'real experts' over there can assist you in your quest.
