Counter-Errorism in Diving: Applying Human Factors to Diving28 Maalis

SH265: Analysis from a Human Factors Perspective - Cave Double Fatality: Calimba 2004

This episode looks at a real cave diving tragedy and uses it to explain how accidents often happen because of human thinking, not just broken rules or bad equipment. Instead of focusing on blame, it shows how choices made underwater can seem logical at the time, even when they lead to disaster. The episode explores key ideas like awareness, decision-making, teamwork, leadership, and psychological safety, and explains how stress, distraction, group pressure, and complex plans can affect how people think and act. It also highlights why good briefings, open communication, and honest debriefs matter, and why teams must feel safe to speak up and challenge decisions. The main message is that safer diving comes from understanding human behaviour, learning without blame, and building strong teams that plan well, communicate clearly, and adapt when things don’t go as expected.
