Smoking and cancer there is a link. Drinking and driving accidents there is a link. Scuba in your backyard pool with a child - I can't find a single link.... Not one...
There are millions of instances of cancer and automobile accidents. Millions smoke. Millions drive. In contrast, only a tiny fraction of the population scuba dives, and of them, I suspect only a tinier fraction ever attempted the backyard scuba thing with children. I would not be surprised if a single death from that has never happened--but it still wouldn't change my opinion that it's not worth the risk for the average diver to experiment with it.
It's hardly worth it for the CDC or anyone else to note whether a backyard pool drowning involved scuba. This will never be a blip on the radar of public health concerns.

I simply wanted to give an--another--account of things going well, from my first encounter with the new-to-me scuba shop, to my kids' subsequent first backyard pool scuba lessons. If the owner and his store manager had had any concerns, they didn't make me aware of them. Maybe our informal chat while the tank was being filled and the paperwork was being completed had something to do with allaying any concern they might have had (if any).
I'm very glad they didn't delay me from what turned out to be a very special first scuba lesson with my children. And when I returned to get the Al 63 filled and again to return the 63, we all shared laughs at the stories I told them about my kids' first encounters. Much fun for all involved, I think.
That may be it. Or maybe they just didn't think about liability. Who knows. I think a shop can approach it two ways: (1) refuse to do anything at all, or (2) gather more information and decide whether the customer seems to have a clue. I like (1), but I wouldn't criticize a shop that chose (2). An argument was made long ago in this thread that if a shop takes path (2), they could be opening themselves up for liability if their judgment proves to be wrong, and I completely agree with that. However, in reality, the risk is low to begin with, and I think a shop employee could be capable of sizing up a customer's plan and ability and renting a tank to the right customer without much risk.
