This sounds like an awesome idea, and the only real issue is making it practical. I know our local site shows a safety video to the punters before they play, could something of this sort (but specially for air/filling safety) be made to show at all events? That'd make it cheap and easy for everyone with maybe a few initial costs? I haven't attended a course so if this is impractical for the situation (or for sites) please forgive my ignorance.
