It may have been an unusual tactic used by Tulsa firefighters that saved lives during a recent house fire. Three of five people pulled from the fire were given a rarely-administered medicine called a cyanide antidote.  Tulsa Fire Department said this likely helped save the lives of two adults and one child who were inside the home. “It pulls the cyanide out of the system and literally converts it to a B-vitamin. It increases the chances for long-term survival,” a spokesperson said.  The antidote helps the body overcome the intensity of the toxic smoke.
