3 Tips for Diving Nitrox Safely

by Cris Merz:
##Diving with Nitrox has brought divers many benefits over the years including longer bottom times, shorter surface intervals, longer repetitive dives, and much more. However, with the good, comes the bad… often followed by the ugly. Nitrox has depth limitations because it increases the risk of oxygen toxicity, among other issues. It is a common misconception that Nitrox benefits deep divers during the dive.

The best way to prepare and plan is to follow three core tips when diving Nitrox.

  • Analyze
  • Label
  • Set Computer

Once you have gone through these three steps, you can establish your maximum operating depth.

Analyze. Take the initiative and put the responsibility in your own hands. It is up to you, the diver, to confirm the mix you have in your tank. Since each “flavor” of Nitrox has a different MOD, you need to make sure yours is safe at your maximum depth and which partial pressure of oxygen is right for your conditions. Many experienced Nitrox divers use a PO2 of 1.6 in warm, calm water, but back the PO2 down to 1.4 in colder more challenging conditions.

Once your tank has been filled, the blender will either check the mixture in your cylinder for you – we advise you to watch – or have you check the mixture yourself. Either method is acceptable, provided you are satisfied that you have the correct gas mixture in your cylinder: because after all, it’s you that has to breathe it!

Label. To complete the process, mark the cylinder Contents label with date, FO2, MOD, Limiting PO2, dive operation name and the name or initials of the person conducting the analysis. Your signature indicates that you take responsibility for the Nitrox that has been delivered to you, and that you are satisfied that your cylinders have been filled properly.

It is important to analyze every cylinder and label the mix on each cylinder. While repeatedly stating this may seem redundant, we know that most Nitrox diving accidents occur when the diver grabs the wrong cylinder because it was not properly labeled, or fails to analyze the cylinder. You need to know what is in your cylinder prior to diving so that you can adequately plan your dive, set the mix in your dive computer and avoid an accident.

Set computer. Prior to every Nitrox dive, you must check your Nitrox dive computer to be sure that it is properly set for the mixture you are using. It is important to remember that there are two settings that you must take note of; the percentage of oxygen and the maximum PO2 to which you are willing to expose yourself. Remember, some dive computers, and their manuals use the term “FO2” (fraction of oxygen). In other words, 32% oxygen is the same thing as .32 FO2 in these cases.

While different dive computers have different default settings for both the oxygen percentage in the mix and the maximum PO2, most default settings tend to be conservative. In many cases, the default setting for the percentage of oxygen will be 21% while the default setting for PO2 is often 1.4. If you do not check these settings and adjust them to your dive plan you will not be getting the full benefit of the capabilities of your computer and Nitrox.

Excellent! You can now plan your maximum depth and bottom time. If you always remember to analyze, label, and set your dive computer to the settings according to your mix as well as your dive plan, you are good to go. And remember, when diving Nitrox; don’t dive below your MOD.

1. Sea-Horse giving birth!


Back when I was guiding dives in the Galapagos Marine Reserve, I had an experience that blew my mind! Talk about being at the right place at the most perfect time to witness this wonder of nature in the birth of new life. I was leading my group along the wall of Cousin’s Rock looking for neat things among the black coral. Some of the main attractions were the sea-horses, but I never expected to see one that was about to give birth! Luckily, my video camera recorded the whole thing.

2. AMAZING encounter (while teaching)

whale shark encounter

The most amazing encounter I experienced while teaching was during the SDI Scuba Discovery course with two participants. The students took to the water quickly and easily during our pool session in the morning but naturally, they were antsy to get in the open water environment to experience diving in the ocean. Little did we all know our open water dives were going to be one of my most memorable experiences in the water! After our first descent, we enjoyed a leisurely dive across a beautiful reef in the Caribbean around 10 metres/30 feet. With limitless visibility in crystal clear water; we saw a green moray eel, a turtle, and an assortment of colorful reef fish but we did not anticipate what was coming next… A massive shadow came over us and we looked up to find an enormous whale shark swimming near the surface! We couldn’t believe our eyes as we remained still in the water, hovering, while watching this incredible creature swim away… To make this experience even better, we were greeted by two manta rays swimming around the boat upon our return! They put on a fantastic show as we conducted our safety stop prior to ascending. Now keep in mind, this was the first diving experience the SDI Scuba Discovery divers experienced and the first time I saw a whale shark! It was an amazing encounter while teaching I will never forget.

August 2014 – Important Insurance Update

Last night we received a fax from Willis Insurance noting they will be discontinuing the Recreational Scuba Diving Insurance Program. This is unfortunate news, as we had a long standing relationship with Peter Meyer and Barb Beauchemin for the last 20 years – as many of you have as well.

It is also unfortunate but not unexpected that PADI’s field reps have used this as an opportunity to call retailers and state that they are no longer insured if they purchased insurance from Willis; or they heard rumors claiming Willis is “dropping” SDI TDI. Nothing could be further from the truth and frankly, this is a simple scare tactic to promote one brand over another.

Here are the facts of your insurance if you have it with Willis:

  1. If you purchased your insurance with Willis prior to August 20th, 2014 – you are covered for the 12 month term of your policy as required by law.
  2. This fax is a form letter required by law to inform buyers that their program will no longer be offered after the policy’s expiration date.
  3. Peter Meyer and Barb Beauchemin were forcibly retired in early July because of internal conflict within Willis.
  4. Willis believed they did not need Peter and Barb to run the Recreational Scuba Diving Insurance program, thereby making the mistake of believing you don’t need diving expertise to run a dive insurance program.

For those of you looking to purchase insurance currently, we recommend you look to the other companies at this time. SDI/TDI/ERDI will have our recommended options in place by 1 January 2015. We deeply apologize for any inconvenience this decision by Willis may cause you, but we will find options and support our membership with a superior insurance program as we have for 20 years now.

Should you have any questions or concerns, feel free to reach out directly to Sean Harrison or myself as we are intimately knowledgeable with the intricacies of the insurance program. SDI, TDI and ERDI remain committed to personalized service to our members and will be devoting our energies to exactly that.

Sincerely,
Brian Carney – Brian.Carney@tdisdi.com

How To: Label Your Nitrox Tank

by Lauren Kieren

Nitrox Tank Wrap

Labeling and Identifying Nitrox Cylinders

Any time you fill a tank with nitrox, it must be identified as such. This will help to prevent accidents in the event that someone uses a tank filled with nitrox without taking the proper precautions. The industry standard for tanks filled with nitrox is to mark the tank with a tank wrap, as well as identify the mixture with a label or tag.

A nitrox tank wrap is an adhesive decal, generally 10-13 cm. (4-5 in.) in width, that is designed to completely encircle the diameter of the tank. The decal is usually printed in yellow and green with the word Enriched Air and/or Nitrox printed continuously on it in bold green or yellow letters. This tape makes it quick and easy to spot a nitrox bottle in a group of tanks.

TDI Contents LabelIt is standard practice to identify the actual nitrox mix currently contained within the cylinder and note it on a Contents label. This information can be found by analyzing, or watching someone analyze, the cylinder for oxygen content using a properly calibrated and functioning analyzer. At a minimum the information recorded on the label should include; oxygen content, maximum operating depth (MOD) of the gas you will be breathing, the name / initials of the person who analyzed the mixture, and the date it was analyzed.

After you analyze the cylinder and find the oxygen content, the rest comes pretty easy. The only additional “how to” necessary is calculating the Maximum Operating Depth (MOD).

To calculate the MOD for a specific ppO2 and percentage of oxygen (FO2) the following formula is used:

Metric
MOD = 10metres X [(ppO2/FO2) – 1]

For example, if the gas contains 36% oxygen (FO2 = 0.36) and the maximum ppO2 is 1.4 bar, the MOD (m) is 10 metres x [(1.4 / 0.36) – 1] = 28.9 metres

Imperial
MOD = 33feet X [(ppO2/FO2) – 1]

For example, if the gas contains 36% oxygen (FO2 = 0.36) and the maximum ppO2 is 1.4 bar, the MOD (fsw) is 33 feet x [(1.4 / 0.36) – 1] = 95.3 feet.

The additional information on the Contents label concerning nitrogen and helium is primarily intended for use by certified TDI Technical Divers trained to dive with helium in their breathing gas mixtures.

Finally, it is important to note that although the industry standard is described and pictured here, some countries require different looking labels by law. A proper nitrox diver course will teach you these procedures and allow you to practice until you are comfortable analyzing and properly labeling a nitrox cylinder.

Gas-Blend

Don’t Trust Your Gas Blender – Analyze Every Tank

by Jon Kieren

Analyzing your tank

People make mistakes, it’s human nature. I make them all the time. I’m sure that even after this article has been edited several times and published someone out there will find at least a couple of typos and call us out on it. A typo is one thing. However, a simple mistake in the blending process can result in a diver breathing a mix with significantly more or less oxygen than they had expected, causing serious injury or death. If we KNOW that people make simple mistakes so often, then why do so many nitrox divers today NOT analyze their gas before diving? There are two primary reasons: either they don’t understand why it’s so important (a topic that is covered in every nitrox course), or they have just become complacent. This article will discuss both scenarios and how to avoid them.

Why is it so important to analyze your breathing gas? Simply, it can kill you if it’s wrong. If the oxygen content is less than the diver had expected, they can end up with unexpected and unknown decompression obligations.

Example – You make a dive to 30 metres/100 feet assuming you’re breathing 32% nitrox. You spend 39 minutes on the bottom and surface with no decompression obligation. Unfortunately, the nitrox tank you were diving was accidentally filled with air (21% oxygen), and in reality you just blew off 26 minutes of decompression. A significant error that is almost sure to result in Decompression Sickness. This situation can be made significantly worse by conducting repeated dives.

What if the oxygen content is HIGHER than you expected? Should be better off then, right? As far as decompression obligations are concerned, yes. However, a far greater risk in diving nitrox is Oxygen Toxicity and can cause severe convulsions (not a good situation underwater).

Example – Using the same dive as above, assuming you were on 32% nitrox at 30 metres/100 feet, your partial pressure of oxygen (PO2) would be close to its upper limit at about 1.3 ata. If that nitrox mix was in fact a 50% nitrox mix, your PO2 would now be over 2.0 ata and would be considered extremely dangerous.

The examples above are not the only concerns of breathing the wrong gas at the wrong depth; a thorough nitrox course will cover the others, as well as how to avoid them. So if you have to be Nitrox certified to dive nitrox, and the risks and proper procedures for avoiding those risks are covered in the course, why do people still end up breathing the wrong gas? The simple answer is: complacency. Over time, divers become complacent with their gas analysis procedures and start to skip it altogether, which means they end up in the water with absolutely no idea what they are breathing. Pretty scary.

Normalization of deviance is a term used by astronaut Mike Mullane (*Mullane 2014) to describe the process of complacency in safety procedures. In brief, it explains how humans have the tendency to take shortcuts due to different factors including time, peer pressure, etc. Once this shortcut is taken and nothing bad happens, the brain will incorrectly assume that the shortcut is “safe”. This shortcut now becomes the norm, and we have completely eliminated a critical step in a procedure. This applies to diving at every level. How many times have you seen divers jump in the water without doing a proper predive check? It is taught and its importance stressed in every open water course, yet it gets skipped every day because so many divers have “gotten away with it” they assume it’s safe to dive without making predive checks and then eliminate it from their procedure. Unfortunately, it also results in emergencies from divers forgetting to turn on their air and inflate their BCDs.

The same happens to nitrox divers. Maybe one day they are in a rush and forget to analyze their gas at the fill station. They get to the dive site and realize that they forgot to analyze but now do not have access to an analyzer. They are left with two choices, either not dive today or dive without analyzing their gas. The diver has been getting fills from that fill station for years and has never gotten the wrong mix, so they decide to dive anyway and assume the fill is correct. Nothing bad happens, so they now believe this shortcut is safe. “If I get my fills from XZY Dive Center, I know that it will be correct and I do not need to analyze my gas”. They have eliminated the most critical step in diving nitrox, and this is now the norm.

We know people make mistakes, and that’s why we have safety procedures in diving. These procedures help us catch the little mistakes before they create catastrophic emergencies. When diving nitrox, analyze every tank before every dive without exception. It could save your life.
