NOVEMBER Meeting Highlights:

There were 15 members at the meeting and no visitors. Primary event was the elections for 2020 Officers. There was no write in or email voting/submittals for the club positions received.

The elected Officers for 2020 are:

Mary Beth Thar – President
Amy Schuring – Vice President.
Ted Tomaszcwski – Treasurer
Don McAlhany – Newsletter/ Club Web Site

Other items discussed or reviewed included:

Discussed the MUD Club having a “Tankful Tuesday” dive schedule of lakes in our home area. Amy Schuring is generating a list of local spots for summer diving and with input will generate a dive schedule. It is anticipated that a club member will volunteer to be the “guaranteed dive host” for that day’s dive.

Other activities happening in mid-November included Sandusky Ohio Shipwrecks & Scuba dive show which will have Kevin & Amy in attendance and the Adaptive Diving Scuba Clinic in Grand Rapids with Bob Sweeney & Karan Mann attending.

There is no scheduled New Year’s Gathering or Dive this year, but Mack will be doing a pickup New Year’s Eve dive most likely and Bob Sweeney intends to dive the Quarry on Jan1.

There is still some interest in looking over Diamond Lake to see if an ecology cleanup of the bottom is feasible. There was no follow up information on the status of Lake 16 platforms being repaired.

Comments were made concerning the newsletter articles on DIN vs Yoke regulators /tanks and a closed-circuit rebreather dive fatality which some believe could have been due to CO2 poisoning.

2020 Diver Related Events:

For those looking for a dive or dive buddy, keep checking in and updating the MUD Club Facebook site for winter “Thrill of the Chill” dives. So far, it’s not been cold enough to build a thick ice base for ice diving.

Divers’ Corner:
Lessons for Life:    Air supply cuts off when regulator failed

A diver’s regulator suddenly failed and cut off air supply, even though there was still a third of the air pressure remaining in the tank.  Now the diver’s story:

I was diving with a regulator which I had purchased eight months earlier. It was the first dive of the day and I entered the water at approximately 7:45 am (with 2910 psi) at which time I descended to a depth of 91 ft looking for sharks.

Relatively quickly, I left this depth and made my way shallower to an average depth of around 60 ft and was photographing along the way. I was diving solo, however there were approximately 16 other divers on the dive at various points along the wall. I passed another photographer in order to stay out of his shot and went on a bit further. Upon seeing a fan that I wanted to photograph, I did what I always do. I looked at my computer to check my air and depth. At that time, I was at approximately 53 ft deep with approximately 1100 psi in my tank.

I took several shots of the fan. I remember completing a big exhale when I finished and righted myself to begin swimming on. However, when I tried to take a breath, there was nothing. I immediately grabbed my octopus, expecting I would get some air, but there was absolutely nothing – no air at all. I did a 360 in the water to see if I could see someone close enough to help and saw the diver I had just passed. I quickly motioned to raise his attention, but he wasn’t looking up and I believed he was too far for me to risk swimming toward him. I made the decision to do an emergency assent to the surface. I was already having the involuntary “pulsing” urge to breathe by this time. At some point, I looked at the computer and it read 000 time/air remaining.

On the way to the surface, I tried again to breathe, but there was zero air. When I popped up at the surface, the dinghy was very close to me, so I quickly got in. I was telling the driver that I ran out of air and had to do an emergency assent, and that I needed to be put on oxygen. At this point, I grabbed for my dive computer and it read 900 psi. I was confused by this (because I saw it at 000) and I tried both regs again, but neither would breathe. I remember showing him the computer and saying something like “There IS air in the tank!”

Upon arriving at the resort, the dive manager put me on oxygen for about 20 minutes or so. I, along with others, watched as he immediately checked my regulator on another tank. I believe it breathed maybe once on the full tank, however not on any partial tank. He took the tank I was using, and in front of everyone, he examined it thoroughly and there was nothing wrong or unusual with the tank. I used this tank the rest of the trip with a new first stage and everything worked fine.

The boat manager tested my system again after the next dive by having someone come back with 900 psi. It continued to fail and would not breathe.

I sat out of diving for about 30 hours and went back with a new first stage system. I had no other incidents with the new first stage, and I was using the same tank that had been used with the failure. I believe this clearly was a catastrophic failure of my regulator first stage, and it failed closed.


Scuba regulators work on a “downstream” principle, where the air flows down from a high pressure to an intermediate pressure and then down to a low pressure. Because of this they are often thought of as “fail safe” because many failures will cause a free flow of air rather than cut off the air supply. Indeed, it is very rare for a first-stage to fail in the way this diver described.

This particular first stage has an Automatic Closer Device to seal the first stage when it is taken off the tank, to prevent water getting into it.

After initially reporting the incident on the DAN Incident Reporting System (DIRS), the diver followed up to report, few months later, to advise that the manufacturer has posted a “Consumer Safety Notice” on their website, recommending a “voluntary product check” because a component of that system may not have been tightened to the correct torque, leading to “a possible gas flow failure during a dive”.

Any diver who owns a regulator that has an automatic closer device should check the manufacturers website for product safety notices.

“Solo” diving, or diving without a companion close by, has gained popularity in recent years since the “self-reliant diver” certification courses became widely available. A core element of many of these courses is the adoption of a redundant air source, in case a failure such as this occurs. Unfortunately, though, this diver was not carrying a redundant air source and needed to make an emergency ascent. Luckily it was the first dive of the day and the diver had moved to shallower water during the dive.

Scuba Safety Alerts -2019

  • Atomic Aquatics issues Low-Pressure Hose Recall – August 23, 2019
  • Dive-Rite issues Low-Pressure Hose Recall – August 15, 2019
  • Danicorp Inc issues Hose Recall – July 31, 2019
  • Mares Recalls the XR Line Inflator – March 21, 2019

Reminder: When is the last time YOU thought about how to respond?

  • To a diver not returning to the surface as planned.
  • Ever wonder where the re-breather diver(s) are?
  • Having a diver surfacing and mention’s they just do not feel good?

Have you ever considered how to respond? Never thought of it?  If not, why not? Plan for the unexpected and think about what you should do in this event.

ANYONE can call off a dive at any time.
It’s *always* OK to say “No.”
