Episode Description
In Part 2 of this blog, we delve into three more of the "Dirty Dozen" human factors—stress, complacency, and lack of teamwork—and explore their impact on diver performance and safety. Stress, whether acute or chronic, can reduce awareness and decision-making ability, while complacency often arises in routine tasks, lowering vigilance. A lack of teamwork, meanwhile, undermines coordination and increases risks during emergencies. Practical countermeasures like using checklists, fostering psychological safety, and setting clear team goals can help mitigate these issues, creating safer and more effective dive environments.
