Bio:
My passion for diving took hold at the age of 11 when I lived in California. At that time, my parents could not afford more than a discover scuba course, but I was hooked. Fast forward 15 years and I found the chance to get fully into diving, cutting my teeth exploring the thousands of shipwrecks that litter the northeast coast. After gaining some experience I moved into technical and CCR diving.

The relationship between national culture and safety culture: Implications for diving safety and organizational culture......13:00-13:50 Hall 2
I am a diver. I am also diving instructor. I have been writing articles about diving, teaching and learning diving and diving safety. In 2020, I have engaged in Human Factors Training. Since then I have been writing and translating articles, and sharing HFiD ideas within Polish diving community.
In high-risk industries, it has been recognised that national culture impacts risk perception, acceptance and compliance with rules and regulations. As diving is an international activity, this presentation will take what has been learned elsewhere and applies it to diving
Long Bio:
I am a diver. I am also a diving instructor. I have been writing articles about diving, teaching and learning diving and diving safety. In 2020, I have engaged in Human Factors Training. Since then I have been writing and translating articles, and sharing HFiD ideas within the Polish diving community. I am also passionate about technical diving. I have been diving for almost 18 years. I used to believe that deep diving, technical diving, or rebreather diving is what interests me at most. But with time I realized that self and diving team development, its what keeps me going. Completing more advanced dives and engaging in more complex projects. I am also a cross-cultural psychologist. Diving is interaction. With ourselves, with others. How we dive, how we teach diving, why we act the way we do. It is how we create and manage the diving environment. I have been dive centre manager in Poland for nearly 5 years. Diving and teaching in cold Baltic waters. Then for another 5 years, I was managing a dive centre in Croatia. Working in a different culture, building up a team, managing a company and teaching technical diving. Human Factors in Diving is a natural continuation of my personal development, and opportunity for me to contribute.

Commercial diving accident: lessons for technical and recreational divers......Day 1, Room 1, 13:00-13:50
I’ve been a diver since the 1970s and freely admit to a particular passion for wrecks but actually, my real passion is diving, diving of any form.
A number of Human and Organisational Performance factors resulted in a near fatal DCS incident during a surface supplied air range commercial dive. This presentation provides an invaluable insight drawing clear parallels with recreational and technical diving.
Bio:
A mariner by profession, I served at sea for over twenty years, eleven of these as ship captain commanding various vessel types but latterly mainly complex offshore oil and gas support vessels. This first brought me into contact with the offshore world of sub-sea engineering and commercial diving. Progression ashore into various ship management and shipping director roles I was involved in bringing a number of sophisticated vessels into service from design all the way through construction and into operation. Many of these vessels were (and are) actively involved in commercial diving operations. Retiring as CEO of a large international shipping company I now provide management consultancy services across a broad international business spectrum. I first met Gareth Lock a number of years ago on a Gema Sim course and was struck by the Human Factors aspects which translated across the entire diving and business spectrum. Understanding and leveraging Human factors plays a big part in everything that I do. Along with helping many businesses to improve, I also provide executive mentoring and of course make time to dive. I recently (along with three diving colleagues) decided to give something back to this wonderful world in which we live and created a Not For-profit entity aimed at supporting the better understanding of the marine, inter and subtidal environments through the medium of Citizen Science. This is a work in progress and we expect the first formal output from this to reach the public domain within this year, 2021.

How human factors can influence the outcome in commercial diving......10:00-10:50 Hall 2

A Voyage of Discovery and Change......Day 1, Room 1, 10:00-10:50
The Messy World of Diving: Diving as Imagined vs Diving as Done.....Day 2, Room 1, 14:00-14:50
Continuing the Voyage.....Day 2, Room 1, 17:00-17:50
Gareth is the founder of The Human Diver, an organisation whose goal is to bring HF, non-technical skills and a Just Culture into the diving domain. He has been working on this since 2010 and would never have thought he'd be running a conference on it!
Voyages of Discovery and Change:
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 second presentation will look at the complex nature of diving and the difference between what should happen on instructional and 'fun' dives and what really happens, and more importantly, why. Recognising, understanding and addressing the gap between Diving as Imagined and Diving is Done is critical to improving diving safety.
The final, closing talk will be a synthesis of the lessons identified during the previous two days and so a detailed synopsis is not available.
Long Bio:
Gareth Lock retired from the RAF in 2015 after a 25-year career involving front-line operations, flight instructing, flight trials, research and development, systems engineering and procurement. Just before he left the RAF, he certified as a technical diver, and ever since, has been trying to bring the tools, skills and knowledge from aviation, healthcare, nuclear, oil & gas and other high-risk domains into diving.
In 2016, he formed the Human Diver and started delivering HF training. In 2019 he published Under Pressure: Diving Deeper with Human Factors and in 2020 he produced and released 'If Only...' which told the story of a diving fatality through the lens of HF and a Just Culture.
His ultimate goal is that The Human Diver is only involved in high-level instructor development and that the materials he and his team currently teach are formally incorporated into training agency, commercial, military, public safety diving and scientific diving training materials.

How to assess and develop Situation Awareness in others......13:00-13:50 Hall 1
Jenny Lord is a TDI Instructor Trainer, Advanced mixed gas CCR diver and instructor for The Human Diver. She lives and works in Dahab, Egypt as a full time instructor of diving, photography and Human Factors.
During this presentation, Jenny will explain what Situational Awareness is; how to assess a buddy or student’s awareness and how to help them improve. This is a must for anyone who has wondered why their buddy has done something very strange or illogical, and instructors who need to develop situational awareness in their students.
Long Bio:
Jenny Lord has been teaching and coaching for over twenty years. She started in the UK as an adventurous activities instructor teaching sports such as rock climbing, white water kayaking, sailing, skiing and caving. She often used these to develop her client’s teamwork, communication skills and leadership, with clients varying from corporate groups to schoolchildren to instructor trainees. Jenny noticed that most of these groups encountered the same problems and needed to learn the same skills set to solve them. When she moved to Egypt to teach scuba diving full time, she noticed a gap in the training and tried to fill in what she could. When she discovered Gareth Lock and his Human Factors in Diving course, she concluded that this was what had been missing and after completing the course as a student, was delighted to be able to continue on and become an instructor. She now wants to help others to fill in the gaps that are missing in conventional training and try to change the systems to make diving safer for everyone.

Bringing HF into Healthcare: Challenges and Successes......Day 2, Hall 1, 10:00-10:50
Simon is the Professor of Anaesthesiology at the University of Auckland, and a very experienced rebreather diver. He was a member of the original WHO Surgical Safety Checklist study group, and since that study has undertaken extensive research aimed at optimising checklists and their use in the operating room environment.
There are many parallels between the complex processes involved in surgery and technical diving; particularly the potential for errors and omissions to result in adverse outcomes. In both fields there has been reluctance to acknowledge human fallibility and embrace strategies to reduce error, but the extraordinary success of simple interventions (particularly checklists) in improving outcomes among surgical patients should now remove any doubt in divers' minds that embracing strategies such as checklists will improve their safety too.

He is also one of the first Human Diver instructors and he is passionate about including Human Factor’s training in all his technical dive training.
It is possible to work human factors training into a technical diving class in such a fashion as it is continually reinforced and referenced in nearly all aspects of training.
Long Bio:
Guy learned to dive in 1982 in a cold mountain lake in Alberta, Canada. He has been a GUE instructor for 12 years and regularly travels the world delivering GUE technical and instructor development programs. He is a former military officer with hands on experience of working in a “just culture”. He is a nationally accredited Skydiving instructor and coach and former professional hunter. He has a graduate degree in political science and has worked in multiple different “high risk” fields. He was one of the first cohort of instructor candidates for the Human Diver instructor program and has presented to multiple organizations on HF in diving. He has worked to include Human Factors concepts into all his training programs and reinforces this message in the various dive communities that he participates in.

Changing attitudes to mistakes in your dive club......Day 1, Room 2, 11:00-11:50
Matthijs is an active recreational diver based in Melbourne and is the current President of the Victorian Sub-Aqua Group, one of the longest-running dive clubs in the world.
How do you change how a recreational dive club thinks and talks about things when they go wrong and how do you use these experiences to improve the learning and safety of its members? Matthijs' talk will go through his dive club has approached this, some of the wins we have had, and also some of the challenges involved in introducing the training in Human Factors and creating a Just Culture into a social dive club
Long Bio:
Having spent his youth watching Jacques Cousteau and want to be a marine biology, Matthijs was first trained to scuba dive in the early ‘80s while at university in Dunedin, NZ. However he only started diving regularly 4 years ago when he retrained along with his son Dylan. Matthijs is now President of the Victorian Sub-Aqua Group (VSAG), one of the longest-running dive clubs in the world and is an active, recreational diver spending hours under the piers looking at wildlife and exploring the incredible wrecks and walls that are readily accessible in Melbourne, Australia.

DAN Incident Reporting - a work in progress......Day 1, Room 2, 16:00-16:50
Frauke Tillmans is the Research Director at Divers Alert Network. 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.
This talk is going to introduce you to the DAN Diving Incident Reporting System (DIRS), how it started, where it stands now, and where it is headed. DIRS is a research tool and is meant to provide divers with feedback on incidents and near misses they report voluntarily and give other divers the chance to learn from those shared experiences.
Long Bio:
Dr. Frauke Tillmans is the Research Director at Divers Alert Network (DAN). She has a PhD in Human Biology and oversees DAN’s in-house research initiatives in injury monitoring, diving physiology, and population health, as well as the DAN Grant Program. A current focus for DAN includes acute diving injuries as well as long-term health effects of diving and extreme exposures. An avid and well-travelled diver herself, she has become DAN’s point of contact for national and global collaborations in diving-related research. Before joining DAN in 2019, Frauke participated in projects covering a variety of medical and health aspects in recreational and military diving. In addition to her research experience, Frauke is an experienced public safety diver, scientific diving supervisor and dive safety officer and diving instructor and has recently developed a passion for cave diving. Frauke’s commitment to safety is apparent in almost every activity she pursues and when she is not diving or supervising researchers, Frauke is an active volunteer firefighter who enjoys endurance and self-defence training. I am excited to speak at the virtual HF conference and engage with an audience that already values the concept of Human Factors. I cannot overstate the importance of communication and the willingness to learn from members of your team or other divers when it comes to diving safety and that will be the focus of this talk.

The Application of Human Factors as an Average Diver......12:00-12:50 Hall 2
Chris is, and always has been, an average diver.
If you're an average recreational or tech diver, how can you integrate Human Factors into your diving?
Long Bio:
Chris learnt to dive in 1995 in the UK and has been consistently mediocre ever since.
He discovered tech diving in 1997 and as funds allowed dived in the UK and abroad, culminating in learning to cave dive in 2014, which now is his favourite way of diving.

From the Stars to the Sea: How Aviation/Aerospace Human Factors has infiltrated Diving and how diving is improving our ability to go to space......11:00-11:50 Hall 1
Sally Tindall is a commercial airline pilot who took up diving to pursue her dream of becoming an astronaut. She had no intention of loving diving!
Wanna know something cool? The early astronauts almost died when attempting spacewalks for the first time. Why is that cool??? Because it was astronauts who had experience in diving who succeeded in spacewalking, diving was a compulsory part of the space program.
Long Bio:
Born in Melbourne, Australia, Sally got into flying for two reasons. One: She wanted to be an astronaut. Two: Her brothers raced cars, and flying was the only thing she could think of that was faster!

Facing diver panic to open opportunities for wider prevention......10:00-10:50 Hall 2
Dr Laura Walton is a Clinical Psychologist, specialising in Diving Psychology; and a Scuba Diving Instructor. Her perspectives on stress, anxiety and panic in diving arise from knowledge of psychological theory, clinical practice and informal observation of diver behaviour.
Entering a state of panic is always possible, even for well-equipped, experienced divers, but it is not inevitable. Building our awareness of the complex factors that interact to spark an episode of panic underwater opens multiple opportunities to face the problem of diver panic.
Long Bio:
Dr Laura Walton is a UK-registered Clinical Psychologist with experience of a wide range of mental health presentations, included anxiety, depression, psychosis and trauma-related conditions. Qualifying in 2010, at the University of Edinburgh, she initially worked for the NHS before beginning private practise in 2019. Offering remote services presented the opportunity to build a niche specialism in Diving Psychology, which is provided UK-wide within Fit To Dive Ltd. In this profession she supports scuba divers following distressing/traumatic diving experiences or seeking to improve their mental, or physical, health.
