Hazard Communication: Warnings and Risk

Abstract

Risk information can alter risk judgments and promote sound risk decisions. Hazard warnings are critical in providing such information. Both right-to-know and duty-to-warn obligations reflect this. Evidence suggests that warnings can significantly affect risk-taking decisions, but care is needed in interpreting whether their influence leads to successful outcomes. Hazard warnings must accommodate individuals' cognitive limitations. Salient problems include recipients who suffer information overload or are unable to grasp adequately the level of risk communicated.
