Got about ten responses so far to the survey, and would like to encourage anyone homebrewing nitrox who has not yet responded to do so. The most interesting thing so far is now professional everyone seems to be. I was expecting more cowboys with homemade O2 whips and a tank of welding 02 in their garage, using a hefty safety margin in lieu of an analyser. So far, everyone who has responded analyses religiously, most use calibrated gauges and O2 clean tanks, and get the mix within 1%. I'll be posting a full report later. A few respondents have taken exception to my use of an alias and an anon remailer, one even speculating I might actually be a PADI agent-provocateur doing some market research. Actually, the reason I used the remailer was so any replies I got would by anon to me, to protect your identities, to encourage anyone worried about liability or being labeled a stroke to respond candidly. For anyone who missed it, here's the questions: 1) How long have you been doing it? 2) Approx. how many tankfuls have you done? 3) Do you use oxy cleaned tanks? 4) What kind of O2 do you use (welding, med, other) 5) Do you use hydrocarbon free air to complete the fill? 6) How do you air fill the tank (your own compressor, dive shop, etc.) 7) Do you use precision calibrated, standard dive/welding gages or other methods to obtain the right mix? 8) Do you always analyse the mix before using? 9) What kind of error do you notice between the desired and actual mix? 10) Have you encountered any problems in the mixing or use of your nitrox? 11) Do you know of any reliable cases of people hurt homebrewing nitrox (details appreciated if you have them)? Any descriptions of apparatus and technique would be appreciated too. Please post or reply by Email.
