Let me Start off by saying this is the first forum i have ever entered, Secondly I would Like everyone no here who I am, I am the Husband Of the recently Deceased woman Killed In Cabo San Lucas On March 3rd of this year. This incident was, I have to say at this point in time (allegedly) by Carbon Monoxide in her tank. We have just had a ceremony here in the Bahamas for her. While i was here, i put my new CO detector to use, I tested over 30 tanks i detected ranges from 1-6 ppm. Wikipedia states that death will occur at 3,600 ppm within 30min. So my question is, does anyone know the formula or calculations for relative surface tests to each level of depth? My wife was only in the water for a total of 10min 26sec. My CO tester has an alarm for 10ppm, but that must translate into a much higher level at depth.
On a second note, I have to agree, that CO testers should be enforced at all dive shops. the reason, well i had a conversation with a dive shop owner and his answer was "I am away from the elements, and i use an electric compressor". well here is my answer to that, CO levels do not have to be introduced once to affect a diver, but repetitive refills some times with low levels building up can result to a fatal dive, so if a fill station is filling someone else's tank and thy use other locations to fill as well, Than TEST THE TANK!! to me it just makes sense! seems we pay more attention to our air censor in our car than the air that we count on for life!
Thanks for any help provided.
