Coming from the flying dodge, where a major effort reduced accident rates dramatically from the early 1950s to today, I am aware of the importance of safety and of properly incentivizing people in that regard.
I thought the sign in this blog post was an effective incentive.
My Father's approach, in his days as a Safety Engineer, centered on empowering first line supervisors. That is something that I have tried to keep in mind over the years--empowering first line supervisors.
