In a paper by the United Steelworkers[ii] in the early 2000’s, behavior-based safety is described as “a variety of programs that focus on worker behavior as the cause for almost all workplace accidents.” This definition of behavior-based safety stems from the fact that in many articles, behavior-based safety is said to have begun with research conducted by Herbert William Heinrich, who worked for Traveler’s Insurance Company in the early thirties. He reported that roughly 90% of all accidents, injuries, and illnesses were the result of what he called “worker errors.”
