The hardness of tungsten rings requires special removal procedures in an emergency situation. There are a few techniques available that may make it possible to remove the ring without damaging or destroying it. Elevating the hand to decrease blood flow and soaking the finger in ice water may relieve enough swelling to permit ring removal. Also, applying soap or another water-soluble lubricant may help. Other techniques have been described in medical literature including the use of umbilical tape or string, or even anesthetic injection to facilitate removal attempts.
