Rebreather diving, while offering unique underwater exploration, poses significant safety challenges due to its complexity. It requires an understanding of both technical skills and human factors that influence diver performance. Key themes in improving safety include adopting a systems-thinking approach, fostering a just culture for reporting errors, and emphasizing non-technical skills like teamwork and communication. By addressing these issues, the diving community can enhance safety and resilience against potential risks. Implementing human factor training is essential, despite challenges in standardizing programs and overcoming cultural resistance.
