Depends on the tank and how much you overfill it. There are some videos on youtube of people who have deliberately overfilled tanks with water until they burst. Generally, LP steel tanks do not burst from "reasonable" overfilling... say 1,000psi over the + rated pressure. I've seen a lot of people talk about going higher than that, but 1k is about my limit for comfort. I've been doing it consistently for just over 5 years now with no problems - including during hydro testing. I wouldn't overfill an aluminum, personally. HP steels are tough to overfill because most fill stations don't bank enough pressure to overfill them a by lot afaik - I don't own any HP so I might be wrong about that situation.
Yes, sometimes I forget the rest of the world does it differently. Now that you mention it, I seem to remember that some people consider valves with burst disks to be less safe than valves without.Tanks/valves made for markets outside North America, Europe and the rest of the world, don't have burst discs
Sure is, I remember seeing that one. I usually take my boots off when diving, put them on for storage. Once you do it a time or two they're fairly easy to install/remove with a mallet.
