I’m frankly tired of hearing the old Heinrich data from the 1930s that asserts, “88% of worker injuries are due to the worker’s unsafe act.” Firstly, it sends the “blame the worker” message that kills cultures. Secondly, somehow this stat has been attributed to behavioral safety programs which, if you know behavioral science you’d know that we always look at environmental influences of behavior (incidentally, Heinrich was an insurance investigator). But my biggest problem with this assertion is that has allowed incident investigation to list “Human Factor” or “Worker Error” to be the “root cause” of an incident.
