For years, safety leaders have been challenged with hitting the goal of zero injuries. Millions of dollars have been spent by leading firms in search of zero, the “Holy Grail” of safety. Many of these efforts have proved beneficial, and yet many others must be questioned. Some of the finest safety cultures meet the goal of zero injuries, only to find that a tragic event shatters zero, leaving it a hollow memory of what was, but no longer is. Why does this happen? Is zero really the right goal, or is there a better one that will drive continuous safety improvement?
