Environmental factors include tools, equipment, engineering design, climate and housekeeping. Then you have the behaviors, the actions of everyone relating to an incident. Finally, there are the personal, internal states of feeling of the people involved - their attitudes, perceptions, and personality characteristics. Take a systems approach in your analysis of environmental, behavioral, and personal factors. Then decide which of these factors can be changed to reduce the chance of another unfortunate incident.
Environmental factors are usually easiest to define and improve, followed by behavioral factors.
Most difficult to define and change directly are the personal factors, but many of these internal feelings can be affected positively by properly influencing behaviors. Improve communication To find and correct the potential contributors to an incident, people need to talk openly about the various environmental, behavioral, and personal factors. People want nothing to do with a failure. It's human nature. Adults will just keep their mouths shut.
