In this episode, we finish exploring the “Dirty Dozen” human factors that contribute to mistakes in diving by looking at fatigue, lack of assertiveness and norms. These factors influence how divers think and behave, and they can increase risk if they aren’t recognised and managed. Fatigue can reduce focus and reaction time, lack of assertiveness can stop people from speaking up when something feels wrong, and unsafe norms can develop when teams skip important steps simply because “nothing went wrong last time.” We discuss how to address these issues through tools like HALT and PACE, building psychological safety, supporting each other as teammates, and challenging negative habits within dive communities. The goal is to create an environment where divers can speak up, look out for each other and make safer decisions together.
