I am a network security engineer, formerly a consultant and currently a sales engineer. For various reasons I can't be very specific, but there are occasions where my consulting clients used a rational risk assessment to avoid risks that could have been extremely injurious to their business and in at least one case probably saved lives. As a sales engineer I have helped customers in similar ways.

In the case of my wife, she was taking the emergency kit I built for her out of her car to save room for a Girl Scout camping trip she was leading. I prevailed upon her to keep it in the car...and she used the flashlight, first aid kit, matches, and multitool (that she told me about). It made a big difference for the Girl Scouts.
