RF4 - Human Factors in Rebreather Diving - 45 mins
The Messy World of Diving - CUCE 2024 - 30 mins

Why this matters. What ten years of The Human Diver has shown about how diving culture handles failure, what has changed, and what has not. And why this week is different from a course

What separates teams that perform under pressure from teams that fragment. Not theory from a textbook — evidence from environments where the cost of fragmentation is measured in lives.

A direct comparison between traditional incident analysis and a Human and Organisational Performance approach. Steve will walk through the same event twice — once through a blame lens, once through a learning lens — and the difference in what you see is the point.

Connor Tate
Research from a US Navy-funded programme combining simulated dive scenarios with in-mask eye-tracking technology and a computational model of diver decisions. What this shows about how experienced divers and novice divers allocate attention at critical moments — and what that means for training.

A practical case for building a dive operation around HF principles, not as an add-on but as the operational foundation. Structured debriefs, psychological safety, communication frameworks, and risk-aware leadership — and how each one improves both safety and commercial performance.

Dive incidents are now investigated on Facebook before the official report is started. This talk examines how narrative, blame, and hindsight operate in online diving communities — and how to engage with those discussions in a way that generates learning rather than noise.

Dr Laura Walton
After a bad dive, most people talk. Sometimes that is not enough. Dr Walton works clinically with divers following potentially traumatic events and will explain why some experiences get stuck, what the psychological mechanism looks like, and what actually helps — both for the diver and for the people around them.

What does the global data actually show? DAN's longitudinal surveillance programme draws on incident reports, medical records, media sources, and investigative collaborations to identify the behavioural, organisational, and contextual factors that appear consistently in diving fatalities. The patterns are not what most people assume.

Gareth Lock
What this day has shown, what the week ahead will do with it, and why the conversation that begins in this room does not have to end when you fly home.

A closer look at the events in Cenote Nariz, Tulum, Mexico in 2024 that resulted in the death of a CCR cave diver. Traditional accident analysis often focuses on the proximal cause and seeks to attribute blame. This presentation will examine the event in depth, focussing on why decisions made sense to those involved and identifying the wider systems, processes and performance shaping factors.

Jenny Lord
Most divers know what good practice looks like. So why do the same problems keep appearing? Jenny draws on experience from liveaboards, guide work, and mixed-team diving to identify the small, practical HF tools that survive contact with busy schedules, tired divers, and imperfect conditions.

How toxic team dynamics create the conditions for incidents long before any diver enters the water. Authority gradients, fear of conflict, blame culture, and suppressed concerns are not personality problems — they are system outputs. This talk names them, explains their mechanism, and offers practical signals to look for before the damage is done.

On December 17, 1944 an American B-24-J heavy Bomber, serial number 42-51430, the Tulsamerican crashed in the waters near Vis after being damaged on a mission against the German oil refinery at Odertal Germany- seven of the crew survive but three are lost.
In December of 2010 the wreckage of the plane was found by a local diver Darko Bojanic. In 2017, after almost a year of planning an international team comprised of British, Greek, Polish, American and Croatian divers begin a project funded by the US Defense Personnel Accounting Agency to recover and account for the three still missing crew members. What followed was a massive, complex and high-stakes project that meshed together teams, cultures and missions.
This talk discusses the history of the site, the challenges of the dive, and the Human Factors challenges that all came together over the six week project.

Jenny Lord
Most divers already know what good practice looks like. So why do the same issues keep appearing on real dives? This talk focuses on the parts of human factors that actually survive real diving — busy schedules, mixed teams, fatigue, time pressure, and imperfect conditions. If you’re about to spend a week on a boat with strangers, diving several times a day, the way people communicate, coordinate, and make decisions matters. Drawing on practical examples from training, guiding, and three human factors-focused liveaboards, the session explores small, usable tools that reduce conflicts, support better learning, and help dives run more smoothly. The focus is on making it easier to do the right thing when conditions aren’t ideal and people are busy, tired, or under pressure.

Silence on the Surface explores how toxic interpersonal dynamics within dive teams and dive centres quietly erode safety long before an incident occurs. Drawing on Human Factors (HF) and Non-Technical Skills (NTS) perspectives, the presentation reveals how fear of conflict, authority gradients, blame culture, and poor psychological safety suppress communication, distort decision-making, and normalize unsafe practices.
The presentation shows how silence—missed questions, unspoken concerns, and unchallenged decisions—becomes a hidden risk multiplier affecting instructors, divemasters, and guests alike. What often gets labelled as “diver error” is reframed as the predictable outcome of toxic systems that discourage speaking up.
The presentation concludes with practical insights for instructors, dive leaders, and operators on how to recognise early warning signs of toxicity, restore psychological safety, and transform silence into constructive dialogue—making it easier to do the right thing and harder to do the wrong thing, both on the surface and underwater.

The discussion about accountability and standards led me to search for this resource. While there will be performance metrics in the CAF, and this shouldn't conflict, these provide clear expectations of what team members should be doing, and allow others (not just the leadership) to hold each other mutually accountable. This framework should be used on a continual basis and not just for the annual PER.

This two-minute clip brings the essence of the course together. Be curious, not judgemental. Look at the background and context, and ask curious questions.
