Being Understood, not just Transmitting

In a recent Human Factors in Diving class we were on a dive where the members of the team were trying to complete a task. It was a mixed group of people, some knew each other well, others had met once or twice before and the rest were completely new to the group. It was also a mix of nationalitie...

Normalization of Deviance (Risk): How Socially Accepted Drift Can Impact Your Diving

Climbing out of the water and back aboard the dive boat in Cabo San Lucas, Mexico, the Divemaster, who was giving me a hand with my equipment, checked my SPG and said, “you have 500psi leftover! You could’ve stayed down another 10 minutes!” Regardless of which organization issued your c-card, 5...

Diving Deep into Diving Safety: The death of Linnea Mills through a lens of HF and System Safety

Diving is often described as a “safe” sport—relaxing, fun, and open to anyone who can pass a basic training course. Yet this simplicity is deceptive. True safety is not just the absence of accidents and incidents, but the active presence of barriers, defences, and a culture that supports learning...

What if Just Culture and Psychological Safety is not enough?

Diving in the Baltic Sea We weren’t diving for pleasure. We had a job to do—marking and documenting selected large elements of a wreck. The pressure was immense. Many factors had to align perfectly at the same time: the team of professional divers, the ship’s crew, the support boats, and the wea...

The Lost Fin: A Lesson in Situation Awareness

Language Matters: An HF Approach to Reviewing an ‘Accident Analysis’

I have been asked a number of times to comment on a 'hypothetical' event published on the RAID website on 7 August 2024 as a learning opportunity. However, it appears that the story wasn’t hypothetical, and the person involved wasn’t directly consulted about what happened. The event had a ‘bad’ o...

Standards- why do we have them and what can we do if someone breaks them?

Living and working in a very active diving area, I frequently hear people talking about courses they’re doing and what they’ve had to do to achieve certification. Sadly, based on not only that but also what I see in the water, it appears that standards often aren’t followed. As an outsider observ...
