In fact, the computer system has almost unlimited ways of helping the firefighters with their problems. For example, it can give medical information about invalids living in a burning building. With this information the firefighters can take special care to find these sick persons and remove them quickly and safely. The speed of a computer is amazing. Within 2 or 3 seconds after a call is received, the computer provides necessary information for the firefighters. The information is then sent to them by the radio from the computer center in the city hall. The Kansas City Computer System also contains a medical record of the city’s 900 firefighters.
