When someone call for a ‘Dr. Brown’ on loudspeakers in any hospital, it isn’t a signal for a Dr. Brown. It is in fact a signal for security personnel to get ready to tackle a threat to personnel. If the doctors or nurses find themselves in trouble with any person visiting them they apply the Dr. Brown code for help. They page their location to security and they rush to the spot to save them.
