Mick boiled it down to very simple things, if it's high pressure or high volume you get a TQ. Better to error on the side of caution here and throw on a TQ.
This is especially true when you have easy access to a higher level of care. If there is an injury to a limb and the thought "wow that's bleeding a lot" pops into your head, put a TQ on it. The Docs can take it off later. They can't bring someone back from the dead.
