Doug, this is bullshit. If you would simply read my section on this topic on WKPP.org, you might just understand for once that convoluted bullshit is not the answer to anything - it is just typical engineer crap. -----Original Message----- From: Doug Chapman [mailto:dougch@ea*.ne*] Sent: Monday, December 17, 2001 7:53 PM To: techdiver@aquanaut.com Subject: Re:100% Helium in Scuba bottles Regardless of the purpose of carrying 100% helium to a dive site in SCUBA type cylinders, AND regardless of how they are marked (and they should be properly marked), the diver after staging his or her bottles topside should always do a last check of the O2 content if 1) The gas was mixed sometime earlier, 2) The gas was mixed by someone else, 3) There is any question what so ever about the mixes, 4) In general do it anyways. If the diver cannot personally supervise and manage the bottles that he or she is going to use during a dive, or redundant checks are considered too time consuming, they should not step one foot in the water. There are no excuses for this unfortunate death if it was by breathing an improper mix. I would not be surprized if the overwhelming number of gas-diver fatalities were due to improper switches or improper mixes at depth??? And they are totally avoidable in all circumstances with proper procedure, training and discipline. 'Something IMHO I believe most "technical" divers are incapable of.
