The Haddon Matrix

The Haddon Matrix is a tool used to improve safety by examining factors in a problem at three stages: before an injury occurs, during the injury, and after the injury. It also considers three groups: the person affected, the environment, and the equipment involved. By looking at these factors, safety professionals can identify opportunities to prevent injuries, reduce their severity, or improve recovery. For example, in car crashes, it helps analyze driver behaviors, vehicle safety features, and road conditions to develop targeted safety strategies.
