Great report of known facts. But, here we go again with assumptions: * Was he diving a mix? * He was "Nitrox certified", was he diving Nitrox? What was EAD, MOD, END, PPO2, etc ? * Tanks have not been recovered for analysis in this report. * No where in the report is it stated that type of mix or normal air. * Narcosis - was he deep enough - Yes. There many other causes, including STRESS, that cause one to loose skills besides NARCOSIS. Some of these are Bad Air, O2 Toxicity, improper breathing, CO2 build up, equipment, preparation, equipment location, planning, etc. Recreational deep still extends to 130 fsw. So does 120 ffw now falls into the category of "Deep AIR"? We need more information from the buddy that was there with him. Check the buddy for panic and stress besides the diver's stress level. > -----Original Message----- > From: Dave Dalton [mailto:dmdalton@ju*.co*] > Sent: Saturday, July 18, 1998 8:17 PM > To: cavers@ca*.co*; techdiver@aquanaut.com > Cc: kirvine@sa*.ne*; JDA000@ao*.co* > Subject: PA Quarry Near Drowning - Deep Air the culprit??? > > > While doing some diving with my son today at the Bainbridge Sportsman > Club, a quarry located 100 miles west of Philadelphia, we > responded to a > call for help from the safety boat regarding a diver lost in 120 FFW. > > When we arrived at the boat we were informed that a diver was > lost in 120 > FFW, the deepest point in the quarry and two divers were down > searching > for him.
