Biscuit7, I just reread one of your posts and I have to agree with you in reguards to the diver who was informed by his or her physician not to dive, and in the event he dives, and as a result, you, as the divemaster are injured because his failure to adbide to their doctors recomendations not to dive, that is a completly different set of circumstances, and I agree, that person is misrepresenting himself Still I fail to see how someone with a known, completly controlled, medical problem,and cleared to dive by his physician, puts you at risk, and is at greater risk of an in water emergency knowing that there are thousand if not millions of people who have undiagnosed conditions that you as a divemaster are taking out to dive, most likely everyday. As a registered nurse in a busy emergency room knows, I put myself at risk everyday, My decisions, My actions, My use of gloves, masks, and gowns during trauma. I can reduce the risk, but if i'm uncomfortable with those risks, how small they might be...well then i should just get out. as a divemaster you can also reduce those risks, and if it means not diving with someone who has answered truthfully on a questionaire then so be it., But my point is you are never going to be without risk of someone who believes himself to be healthy and later finds out that he wasn't, you might even find out after you pull him out of the water unconscious. The questionaires are useless and doesn't protect anyone, I believe them to even promote medical descrimination
