The employee was killed as a result of his injuries.

Contributing Factors

Employee did not use fall protection.

What Can We Learn?


Following the Procedures would have prompted the employee to utilize the mandated and provided fall protection.  

By using a Questioning Attitude the employee would have considered the worst thing that is most likely to happen causing him to utilize fall protection.


Overconfidence caused the employee to overestimate his abilities, underestimate the risks, and exaggerate his ability to control events.   

Time Pressure may have caused the employee to overlook the fall protection provided in order to take short-cuts to complete his work faster.
