As for safety rules, I'd agree with the PP. We tried "HEY, KIDS! ONLY ONE AT A TIME!!!" but that just wasn't as much fun. Shoes off, no pushing/knocking down, and stop if anyone seems uncomfortable or upset. Kind of the same rules they're trying to set on college campuses these days.
And for what it's worth, we've found that setting up a sprinkler underneath is a GREAT way to spend a hot afternoon.
