How long do you keep a tourniquet on?
A tourniquet should not be removed at all. Tourniquets are a LAST RESORT method. They are hard to apply, they cause a lot of pain, and they can lead to the loss of any limb below wherever the tourniquet was applied. However, if the choice is your LIFE or your LIMB, choose the life. Apply the tourniquet and tighten it until the bleeding stops. Secure the stick to make sure the tourniquet does not loosen and DO NOT TOUCH IT. Get the victim to a hospital immediately. Once there, the doctors and nurses are trained in how to remove tourniquets and treat the wounds. If you leave a tourniquet on too long, the person might lose their arm/leg/whatever. If you take it off too soon, they can easily bleed to death.

How come that when you put a tourniquet on the arm it becomes gangrened?
A tourniquet cuts off blood flow. The arm or leg will not immediately become gangrenous. First, the skin would feel numb. The arm would begin to throb as if it 'went to sleep', with tingling, burning, etc. The person would likely be wiggling their fingers to get feeling back and would remove the tourniquet at that point, if lucid and not in shock from bleeding. If the restriction to blood flow was left on, the skin color and temperature would begin to change. The fingertips (or toes) would die first.
