I don’t think you appreciate the mechanical energy stored in these tanks. The chemical energy is not the problem as you pointed out. Do you know a tire rupture can kill somebody at short distance? Well these tanks are using 200 times more pressure and multiple times the volume (stored mechanical energy increases linearly with both pressure and volume).
