1. Expose the injury, assess the bleeding source (assess for unrecognized hemorrhage), and control all sources of bleeding. 
  2. Control life-threatening external hemorrhage that is anatomically amenable to tourniquet use or for any traumatic amputation.
  3. Remember: Bleeding should be stopped within 1 minute and the tourniquet fully secured within 3 minutes.
  4. The time of tourniquet placement should be documented on the tourniquet itself and on the DD 1380 in TFC (but not during CUF).
