It's not dangerous by most people's standards - that's one of the reasons people get so uptight whenever the subject of "accidents" arises! >Do boilers explode on > a regular basis? I don't think there has been an explosion of a silver soldered copper boiler but I can't say for sure as accident reports are not published in the model engineering press.
