In this episode, we explore the critical role of understanding hazards in diving and the importance of effective risk management. From the everyday threat of drowning to the more abstract risks like decompression sickness, we discuss how divers rely on equipment, training, and planning to mitigate dangers. The conversation highlights overlooked hazards like differential pressure (DeltaP), which can be deadly when misunderstood, as illustrated by tragic real-world examples. We also examine the psychology of risk normalization, emphasizing that ignorance of hazards can lead to complacency and tragedy. By raising awareness and promoting informed decision-making, this episode underscores the necessity of knowledge, preparation, and humility in diving safety.
