Solving difficult problems far below the surface

Published

on

By Jon Kieren

You are 100 m/330 ft under the surface. You hear a massive rush of bubbles behind your head. This can play out one of two ways:

  • One way begins with you signaling your teammate and maintaining position in the water column. You reach back to close what you believe is the affected post. Together with your teammate, you identify and isolate the failure. You clearly communicate the problem within the team. Everyone knows what resources have been affected (gas supply, wing/drysuit inflation, etc.). You end the dive and begin to ascend.
  • The other way? That s when things don’t work out as well.

When things don’t go quite as well 

When the failure occurs, your stability is rattled.

  • While reaching back to close the affected post, you turn away from your team. In so doing you lose reference of your position in the water.
  • As you struggle to close the valve, you become increasingly stressed. CO2 begins to build up in your bloodstream as your heart and breathing rates increase.
  • As tunnel vision sets in, your buoyancy begins to shift from the change in your breathing pattern. Due to your subconscious and erratic finning, you begin to ascend. You are so focused on closing the valve that you don’t realize you are ascending.
  • When you finally realize you are ascending, stress increases and panic sets in. You no longer have the capacity to rationalize the situation.
  • Instead of focusing on the buoyancy shift and managing the ascent, you continue to try to close the valve. Your ascent becomes rapid and uncontrollable.

By the time you hit the surface, you’re dead.

This situation can occur under a wide variety of circumstances 

Minor errors or failures can quickly cascade into real emergencies. This is true whether you are on a shipwreck in deep open water, far back in a cave or even on a shallow reef.

When we look at diving accidents and incidents, it is almost never an equipment failure that is the end cause of a fatality. Such failures are usually several steps down the error chain as things cascade from an inconvenience to an unsurvivable situation.

We often chalk these accidents up as human error. We think, “Well, that was stupid. That’s not how I would have reacted. I would have been able to control my buoyancy. I’m awesome”.

The “Incident Pit” Concept 

At the 1973 British Sub Aqua Club Diving Officers Conference, E John Towse introduced the Incident Pit concept. This concept essentially explains that as problems arise and are not managed properly, they become more difficult to manage.

We slide deeper into this pit, eventually unable to extract ourselves or teammate from the situation and it becomes unsurvivable. This concept is easy to visualize, but many of us often miss where the true failure lies: Stability in the water.

As a dive progresses, we operate on the first level of the incident pit. We manage normal situations such as communication, buoyancy changes, navigational decisions, etc. with relative ease.

But what we often don’t realize is that, in conjunction with a high level of attention being placed on our buoyancy and stability, our capacity to handle more complex tasks like equipment failures is limited. So when a problem does arise, it is the foundational skills that fail first as we become fixated on resolving what appears to be the priority.

When our stability fails, that’s when we quickly slide deep into the incident pit. Visibility is trashed due to making contact with the bottom. We get swept off the wreck or ascent line in the current, or we make and uncontrolled ascent. Now, a minor issue creates an emergency.

So how do we resolve problems in extreme environments?

Start with a solid foundation. Practice until you can handle basic tasks such as valve drills and S-drills until you can do so while maintaining a precise position in the water. Be able to do this without sculling, finning or needing to focus on buoyancy and trim.

Breathe appropriate gases that reduce equivalent narcotic depths and gas densities. At this point, you will be able to reserve the capacity to stop and think rationally through problems that arise. You will be able to assess your situation, evaluate what resources are available and take decisive action that will resolve any issues.

Most of the time, you’ll probably be fine. However, problems do arise on dives. It is the nature of the sport. Failure to place emphasis on maintaining a solid foundational skill set is setting yourself up for failure to manage these situations. It is your responsibility as a diver, as well as a teammate to keep these skills proficient.

From its humble beginning in 1994 to today, the group of training agencies Scuba Diving International (SDI), Technical Diving International (TDI), and Emergency Response Diving International (ERDI) form one of the largest diving certification agencies in the World – International Training. With 24 Regional Offices servicing more than 100 countries, the company today far exceeds the original vision the founders had when they conceived the idea on a napkin, sitting at a kitchen table in the early 1990’s.

14 Divers You Do Not Want To Be On A Scuba Diving Charter Boat! (Watch Video)

Published

on

We’re counting down some of the scuba diving etiquette faux pas that I see week in, week out on dive charter boats. I’m giving you my best advice to not become ‘THAT’ diver and stay in the good graces of you Charter Boat Scuba Captain and Crew.

This is stuff they just don’t teach you during your PADI Open Water Course! The unwritten rules of scuba diving. Good behavioral habits to develop to be the scuba diver that everyone looks forward to having on their dive boat.

I’m drawing from my experience as a charter boat Captain, but also asked a whole bunch of my friends in the Scuba Diving business for their input on what divers do to drive them crazy! Thanks for your input!

I’ve been asked for this video a bunch. Let me know in the comments which diver stereotypes I missed!

Thanks for watching!

My Dive Buddies Episode 3: Jimmy Gadomski’s Sunken Treasure (Watch Video)

Published

on

My Dive Buddies Episode 3: Jimmy Gadomski’s Sunken Treasure! I’ve brought in my good dive buddy Jimmy Gadomski to the dive locker to regale you with stories from his treasure hunting exploits. We’re also talking the difference between being a recreational dive boat captain and a technical dive boat captain and discussing what has gone wrong with so many near-misses/almost-accidents.

Jimmy is one of those great guys who can’t walk past a muddy puddle without wondering what is at the bottom of it. He shares his insight on how he decides if a student is ready to start tec training and how to train a dive master to run tec trips. He also makes me killer jealous with his stories of diving the wrecks of the Great Lakes – something I was supposed to also do until COVID-19 got in the way!

And as always, Jimmy faces the 10 questions we ask everybody.

Here are the timestamps:

  • Intro: 00:01
  • Jimmy’s jobs: 01:03
  • How Do You Decide If A Potential Student Is Ready For Tec? 02:15
  • Considerations for running a Tec Charter boat: 04:18
  • Service and Safety in Tec Diving: 05:47
  • What’s happening with all these near misses this summer? 06:46
  • How can the Tec Diving community identify safety concerns? 10:12
  • Show and tell! 13:51
  • Gold and silver coins: 16:36
  • Great Lakes diving: 18:52
  • 10 Questions We Ask Everybody: 20:50 Cheers! 22:48

I really hope you guys enjoy watching this series of videos as much as I enjoy making them or else it wouldn’t be fair!

Thanks for watching. D.S.D.O James
