Question about Oxygen Exposure

[Hawkwood]

Yes, there is an "exam" and you will have to know how to use the tables for the exam;

You will work through a number of sample problems using the "tables"; and,

You will have to plan an enriched air dive using the RDP, DSAT Equivalent Air Depth and Oxygen Exposure Tables and Enriched Air RDPs.

Most likely your Instructor will have you plan a number of dives with different blends and different dive parameters.

So the bottom line is this: The OP poses the wrong question. Why seek to avoid any portion of the content of the course, or minimize its importance based upon whether it is on a test? While anyone can can grab a tank of Nitrox and go diving, there are special rules and hazards when using increased partial pressures of oxygen. Rather than seek to avoid information, or skim over it, I would hope that the OP and everyone else would want to master the information, be in the habit of carrying their tables with them for the reasons given, and always check their dive profiles and accumulation of O2 time to maintain a proper safety margin. Take the course to learn stuff, not just to get the card.

I agree with DivemasterDennis. When i dive nitrox i use the tables to calculate 02 tox and the like to make sure i don't hit 100%. While computers can help, they can still fail. A table will only fail if used wrong (practically impossible with training and constant practice), or lost. I often test myself to make sure i get the correct outcome, and read the books and manuals. Also, you should learn the material to learn it and have it in your back pocket and not just learn what is on the test. Example, i learned how to change a tire, check oil and the like when learning how to drive. Where i am, this was not part of the road exam, but it is practical information.

I'm sorry but what part of my original posts says I am avoiding anything?

I asked if there was a test (since I wasn't sure and the book didn't indicate it) and if the information for the Dive Table was required for the test. Not once did I say I didn't want to learn it, I actually said I would read it. I needed to know if it was a requirement for the test so that I would need to know it for the test.

Further to this, the Dive tables wasn't my strongest point when I did my OW course, especially multi-level diving. So if there is indeed a test on this I will need to work extra hard on it to get my head around the concept and getting used to using it the table and the formula for it.

Oxygen should never expose itself. No one wants to see that sort of thing.

You might want to consider getting better at this. It's kind of important.

I know and I am.

I agree with everything said above, but show me a recreational diver who runs out of oxygen clock and I'll send you a warm beer.

Wouldn't take long to run out of O2 limit when you're doing deep altitude dives ;-) Shall I have my beer now or later

 

[Superlyte27]

well i dive with the Suunto viper (that has a manufactures defect) that even at o2 pp at 1.5. it gives you full o2 toxicity in about 35 min of diving at a depth of 34m. so need my address for that warm beer

34 meters on what gas? Their average depth is 34 meters for 35 minutes at 1.5? I don't care about your bad computer, at 1.5ppo2 your oxygen clock is good for more than 35 minutes.

Be more specific and I'll show you that the dives you are doing are either using the wrong gas, or not "recreational".

Recreational divers (as trained by PADI) don't dive at 1.5ppO2. Beer denied...

That's how I can tell you weren't Army. No rational statements are EVER allowed to get in the way of a beer
