The high pressure hose has a flow restrictor built into it to prevent large gas loss from a leak. Look at the first stage end of the HP hose and you'll see a pin hole. This was Chuck's point. More gas is lost per minute from a low pressure leak because the flow is unretsricted in an LP hose. That said, the pressure in the HP hose is tank pressure. As such, it has the potential to propel an SPG a short distance if the SPG comes off. Hence my point about the missile.

A leaky hose will not cause the tank to take off. Only catastrophic failure of the pressure vessel itself will do that. In such an event the tank is more of a bomb than a rocket, though the valve would probably resemble an RPG.
