In 1936, a critical event happened that changed aviation safety and saved Boeing from bankruptcy. It was the development of a checklist to help pilots remember critical steps. In 1947, researchers Fitts and Jones published a paper that said “Practically all pilots of present-day AAF aircraft, regardless of experience or skill, report that they sometimes make errors in using cockpit controls.". The point they were making was that human error was everywhere and they needed to design 'systems' to take human variability into account.

Over the coming decades, change happened but it wasn't easy. People don't like change, but when those in charge realised it could save them money, and increase their positive reputation, they started to build human factors and non-technical skills into their aircrew, engineering and ATC training programmes.

Over time, these programmes have been copied and modified to allow them to be used in healthcare, oil & gas, nuclear power, construction, veterinary practices, all with positive outcomes.

This introductory presentation will set the scene for the conference, highlighting the voyage divers have been on regarding HF in diving and what to expect over the two days of the conference.

The Just Culture process, originally introduced by James Reason in 1997, remains a popular framework helping managers to decide how to respond in cases of human error or non-conformance which contributed to an incident. However, over the years, the available evidence indicated that the original design contributed to the misapplication of the process and in some cases led to outcomes not aligned with the intent. Therefore in 2012, BP started a re-design that improved Reason's original framework towards one informed by recent studies in cognitive and social psychology, organisational justice, systems thinking and incident causation.

Change can be introduced into an organisation using a combination of enforcing rules/guidelines and embedding them in the culture. In a social, dive club, there is much less scope to enforce change, even just to get the ball rolling, so trying to change the culture is the main lever that has to be used. With a diverse group of people who are primarily out to have some fun and only get together irregularly, this can present some challenges. However, the rewards of seeing behaviours change and club members doing the right thing because they believe in it and because they want to, makes the effort worthwhile. This talk will go through how our dive club has approached this, some of the wins we have had, and also some of the challenges in introducing some of the training in Human Factors and creating a Just Culture in a social dive club.

A strong prevention bias in safety thinking doesn’t offer a robust understanding of the complexity of high consequence events. Despite the best risk assessments, procedures, and people, we simply cannot prevent all incidents. We must instead balance prevention efforts with capacity to respond and recover when things go badly. But how do we apply this in our diving?

This session offers a simple visual model (along with a backstory) to stimulate discussion and promote learning, shared understanding and a language of safety differently, in the context of the buddy system in Scientific Diving. The model is an adaptation of the bowtie model – but with a twist.

On one side of the traditional bowtie model, prevention efforts deter threats, while on the other side capacity to respond to events reduces impact. The centre represents operational activity and an event moment. This is also the moment when people recognize anomaly and make sense of the information, learn in the moment, and innovate a change to the system.

In our adaptation, the bowtie is depicted inside a sphere of influence representing the margin of manoeuvre. Positive influences create an outward force to maintain a buoyant sphere. Negative influences put pressure on the system, reduce its size, robustness and even collapse it. An unbalanced bowtie can also collapse the system.

Then we shift the model from bowtie to propeller, making it dynamic, and demonstrating how learning creates a feedback loop to improve the entire system- including preventive, operational and response/recovery components.

Dive Masters deal with different divers all the time. These divers come from different cultural backgrounds, different training organisations and have different levels of ability.

A qualified Dive Master will routinely take a diverse group of people diving in good conditions at familiar dive sites without suffering serious mishaps. However, there are often little things that happen that weren't part of the plan that gets ignored or forgotten and are rarely discussed after the dive.

When incidents do occur, it is often as a result of lots of these little mishaps coming together at the same time. By discussing real-life diving incidents,

Mike will look at several different examples of Human Factors where Dive Masters were involved and what can be learned to try and avoid similar incidents happening in the future. The main aim is to provide some specific advice on how Dive Masters can apply Human Factors to make their diving and that of their fellow divers safer, more productive and more enjoyable.

Mike is an experienced military pilot and flying instructor in his day job and works as a Dive Master at weekends. He is also training to become an instructor for The Human Diver and is always striving to improve diving by applying Human Factors.

In December 2018 a young and fit commercial diver suffered near-fatal injuries arising from a poorly managed series of dives using ‘no stop/no decompression’ tables.

“Deep, dark and dangerous” and “How can this be of relevance to me?” I’m sure you are thinking? This was a surface supplied commercial dive after all.

This is of direct relevance to you because it was the result of a series of 5 ‘no stop’ dives conducted over a number of days and all to circa 20 metres water depth and all conducted using air as the breathing gas. Just like your own holiday and expedition dives I’m sure. OK, he was working hard but then again, we all encounter hard work on dives too, often due to current and having to fin hard. His daily dives were run according to USN 7 tables for repetitive diving.

The dives did, however, push the defined limits and during his last dive, he experienced what can only be described as a more-than-usual rapid ascent to the surface. The rapid onset of what was subsequently identified as a Type II DCI, vestibular bend was then compounded by what can only be described as poor emergency management. It took 6 hours to get him into a chamber for recompression and this involved a helicopter flight to a neighbouring island. Incredibly there was a chamber 4 minutes away from the site of the incident but the supervisory team on-site decided not to use it.

There is more, much more and this presentation provides many learning points for us all, no matter what type of diving we do. Human physiology is common to us all, as are the laws of physics. Lewis wants to share what happened to him so that others may learn and avoid what happened to him. He wants us to benefit from his near-death and certainly life-changing diving incident.

Bio:

I’ve been a diver since the 1970’s and freely admit to a particular passion for wrecks but actually my real passion is diving, diving of any form.

When a dive incident happens, focus is often put on external factors and in serious accidents often scarce and misleading news is published by specialised as well as general media.

With an average of 5500 emergency calls received every year worldwide - ranging from trivial to deadly - the DAN team has been collecting a wealth of data in its 40-year-long history.

The presentation aims at shedding more light on what really happens when the alarm centre is notified of an emergency, the procedures followed to promptly respond, the service providers involved, and how all this is coordinated to improve the diver’s conditions and avoid further damage.

Some real case scenarios will be provided, to add a more practical, concrete perspective on the subject.

The data collected and the experience gained also allow us to analyse what are the most recurring incidents and why they happen, providing interesting considerations about human factors as well.

As human activities become increasingly complex, operational failure due to omitted critical steps becomes more and more likely. In many fields, this can result in serious injury or death. Relying on expertise or experience alone introduces a failure mode related to the wide range of conditions that can negatively impact the operation of the human brain. Anger, sickness, distraction, and other such states can make mnemonic devices and well rehearsed routines fail, with catastrophic results. A physical, printed checklist, when combined with appropriate procedures for following such a list acts as a line of defense against such failure. These lists have been successfully implemented in a number of high-stakes fields, such as diving, surgery and aviation. This talk will review their use and make recommendations for implementation by scuba divers to enhance safety.

We now have multiple decades of CCR operation by sport divers. Over that time, diving knowledge has improved, manufacturing has improved, training has improved, data recording has improved and the factors contributing to incidents has shifted accordingly. This shift has reduced some factors, leaving human factors in a more prominent role. This presentation explores how human factors are addressed in safety testing and outlines some scenarios where this approach could be updated.

Most technical dive training focuses on equipment management and technical skills such as buoyancy control. Little to no time is given over to non-technical skills such as decision making and communication. Yet, these factors can play a critical role in how a dive team performs under pressure. It is possible to thread an awareness of human factors through technical training from day one. I have been doing this for several years and I have developed and will share some useful strategies that I have found successful.

DAN has collected diving incidents and fatalities for almost four decades. A number of the voluntarily reported incidents have been published in the Annual Diving Report or were featured on the DAN.org website or in Alert Diver Magazine. Since 2012, the DAN Diving Incident Reporting System (DIRS) is an online application and has collected hundreds of incidents and experience reports that divers were kind enough to share. The incidents cover everything from pre-planning of a dive, to equipment failures at the surface or in the water, to adverse situations during a dive that triggered an undesirable outcome. Divers share these experiences about these events, including mistakes that were made, injuries that occurred and possible contributing factors with DAN in the hope that others can learn from their stories. DIRS has recently undergone some changes and has incorporated more detailed questions pertaining to Human Factors, which will be highlighted in this talk. You will learn how the DAN team reviews the submitted incidents and what you can expect from us when sharing your experiences with us.

With a PhD in human biology and extensive experience in different areas of diving, including recreational, technical, cave, scientific, and public safety, she has brought some new perspectives into the injury monitoring initiatives at DAN.

Accidents happen, no matter how hard we try to keep divers safe, because people make mistakes.  For example, in a review of 1,000 recreational diving mishaps performed in Australasia, 87 percent were found to be caused by human error; while inexperience and insufficient training accounted for 14 percent and eight percent, respectively, of the contributing factors to mishaps.  In other words, the vast majority of accidents happen because people make a mistake, with a smaller number caused by people getting in over their heads.  For this reason, when a diving accident occurs, an investigation of some type usually follows.  It is important for you to understand the process as the investigation moves forward.  This presentation describes, in detail, what happens after the accident.

Both technical diving and the intraoperative care of surgical patients are complex processes with much potential for human errors or omissions to result in poor outcomes. Both technical diving and surgery are undertaken by highly trained individuals who place great importance on their expertise and competency, and who are at risk of failing to fully acknowledge their inherent potential for fallibility. Failing to confront fallibility may be encouraged by the fact that things go well the vast majority of the time, potentially feeding complacency, a self-perception of being 'above error', and a reluctance to embrace (perhaps even contempt for) strategies that implicitly acknowledge fallibility and attempt to prevent it (such as checklists and team briefings). The surgical world was forced to confront this issue after the publication of the original WHO Surgical Safety Checklist study and other follow up studies which confirmed the finding that introducing a simple checklist process to the operating room reduced patient deaths and complications. In the decade since, there has been a generational swing toward adopting human factors strategies to reduce error, with further evidence of improved patient outcomes. This extraordinary result should be carefully scrutinized by technical divers who are much less advanced down this path. This presentation will explain the relevant research in healthcare and discuss why it is directly applicable to divers. The principles of adopting processes such as checklists (and related pitfalls) will be discussed culminating in advice that could be translated directly into practice and will almost certainly save lives.

Panic is a physiological and psychological state that can occur when a person is under stress. It involves extreme levels of emotional arousal (high or low) and associated changes in thinking, information processing, and attention. In this state, a person is not able to think clearly or consciously control their actions. Behaviour is instinctive, and the brain drives processes for immediate survival; leading to actions which can be effective on land, but are potentially fatal underwater. Entering a state of panic is always possible, even for well-equipped, experienced divers, but it is not inevitable.

The penalties and consequences for incidents and accidents in a scuba diving operation can be severe. In addition to the associated human anguish, a serious accident can close the business or result in criminal legal proceedings and jail time for both dive professionals and owners. It is a constant balancing act to create a fun day out for customers while managing people's egos, the urge to cut corners to be more efficient and some divers' capacity to try things that exceed their training due to peer pressure, or just because they don't realise the risks they are taking. This presentation looks at how HF can play a structuring role in dive centre management and continuous improvement.

Military diving operations may vary from short and simple missions to long and complex operations. The military diver has a large toolbox to get the job done. The clearance divers normally dive scuba air, surface supplied diving and different rebreathers including ECCR. Typically, the dive equipment is just a transport method to be able to complete a task. However, the wide range of opportunities also increase the probability to make mistakes and end up with serious incidents. Military divers work in teams where stress, decisions, teamwork, attitudes and positive culture are critical elements in success. This presentation focuses on how to minimize the risk and use CRM at an operational level in military diving operations.

In November of 2012 during a routine training dive to 36m (120 ft.) National Park Service diver Dave Conlin experienced a dual sensor failure on his ccr which lead to a hyperoxic mix in his breathing loop, an O2 seizure at depth, an uncontrolled ascent from depth, almost a week in hospital, hundreds of thousands of dollars in expenses for the National Park Service and an internal investigation spearheaded by law enforcement that lasted almost two years. This presentation looks at the root mechanical, procedural and human factors causes of the accident, but also looks at the experiences of the subsequent investigation by the prime subject of that investigation- Dave Conlin. This presentation will attempt to take a broad perspective on an accident that happened almost a decade ago with the caveat that this is a personal account of events by one participant deeply involved in events.

Human factors or non-technical skills are important to increase the safety of diving. Divers from every level can benefit from learning about human factors. To ensure new divers will understand and integrate human factors in their diving, examples used to illustrate the concepts must be practical and adapted to their level of training. This talk will discuss the importance and the benefits of introducing human factors early in the training of divers and will identify ways of presenting these non-technical skills to novice divers.

This presentation will focus on the power we each possess in shaping our diving community as well as the future generation of divers. Using personal stories of tragedy, triumph, teachable and learning moments, we can build upon this incredible community through sharing personal experiences. From “Uh-oh” to “Oh god, I can’t believe I did that…” we’ve all experienced moments of panic or frustration underwater, but we’ve all survived and lived to tell about it. That sets us apart from some, and lessons are learned through shared experience, so let’s talk about the value of sharing these moments with others. What are some moments you wish you could go back and re-do? What lesson did you learn from that experience? Would somebody else find that information valuable?
