I'm not sure where you're coming from here Dick. Safety "is" the first priority. That said, it is and always has been "safety at a price" we will never remove human frailty and so accidents will continue to occur. It comes down to we either do or we do not do, That involves risk assessment and management. The key is to identify what can be done with a higher degree of safety without incurring cost. Sadly identifying those things, usually come about as a result of an event.
