because the same types of things often catch my father off guard as well, specifically like having to show your sea card before getting a fill or jumping into the water, since when my father began diving no one ever dreamed of an actually card in order to dive, you either learned what you were doing or you take your chances with death.
Again I disagree, banning sports in gym class like dodgeball or tag is an example of an overexeration of a remote possibility of danger in order to push upon children whatever their specific agenda may be.
The fact of the matter is that Diving, especially diving that involves a more serious understanding of actual physics and physiology such as deep dives or Ean dives, Tech etc. is actually a really really really easy way to get dead, all things considered. Just the same as is involved in Aviation, or Motorcycles, or Track days, or mountain climbing.
In diving its called a buddy check. BWRAF. Aviation when someone pushes a bad position to the point that it kills them its often due to 'getthereitis' or not filing a proper flight plan or ignoring the weight restrictions of your aircraft. in diving its called forgetting to plan your dive and dive your plan, or getting into something over your scope of training, like and overhead or enclosed environment, aka IFR flight.
Diving is dangerous, and most of the old timers or most experieinced divers are almost always the ones with the least amount of bull**** hanging off their BC's, the simplest setups and the most redudant backups.
Honeslty though, if you think refusing to work in a confined space with a large store of compressed 100% O2 a metal tank that's under 3k pounds of pressure all cramped up in a tiny room with what would conservatably be about 6-10 realstic ignition sources all around you for a lousy 7 bucks, I guess I have nothing to tell you.
That O2 is separated and compressed by a compressor which is relys on an ignition source of some kind to operate, There are outlets everywhere, metal tanks that fall onto metal tanks, we u/w strobe that burn out or burst etc. Theres a reason that o2 therapy requires an RX from a doc, and that as a FF and EMT we cant transport large tanks of O2 suppy ourselves nor can it travel by Air and it generally requires a hazmat plackard be displayed while underway on the road.
We can both agree that regular gas is pretty damn flammable right? and they let 16 year olds pump it, transport it and come in contact with it nearly every day, oxygen is still technically a prescribed drug or a hazardous material depending, its not a fear without merit
I dont think we call all agree. everything you have mentioned is divers not diving. divers kill not the sport. regular air i hazardous material because it is under preasure not because of the gas mix. air is not "pretty damn flamible". high O2 concentration contributes to flame. lets see <40% treat as air.
as long as that 16 yo has the training to pump i let him pump. would ii ask for his gas filling/blending card. nope. would i ask if i was getting trimix. maybe but probably not. would i check thier work. you bet ya.
New divers do carry more crap, once again the diver not diving. fashion not function.
O2 theropy is MEDICAL TREATMENT usng non standard gasses. Just like a drug it is not the drug that damages it is the user that causes the damage by iresponsible behavior.
Do you think that if it were really dangerous you could get life insurance. nope,,, at best not covered if death is by diving.
There is a lot to be said for the "OLD TIMERS" who did this stuff when it was a young sport. no one got me in to make a buck. my instructor made a portion of the 40 buck for the 6 week class, half of which was the "C-CARD) BC's did not exist. regular air either non or pepermint flavored was pumped. you did not need a card only a tank. people did not retire from sueing. O2 cleaning was not required for anything above 23.5%.
It is sad to see new divers subscribe to the philosophy of everything is dangerous and thus needs special everything to get by. $$$$$$$. If those who do treated walking across the street the same way as the diving scare they would still be holding thier momma's hand to cross. (for a fee of course)
