In terms of managing high risk environments i would say yes, its the lowest risk practice, in my experience people who argue for higher risk solutions are never involved in managing those environments.Is it necessary, though?
I work in a high risk environment every day, i am more risk adverse than all of my management, the further from the floor you get, the higher the threshold for risk gets. There is good reason for this, senior managers and politicians are concerned with appearances, im concerned with not getting a life changing injury.
