Computers Help Fire Fighters

In Kansas City, Missouri, a computer helps fire fighters. The computer contains information about every one of the 35000 street addresses in the city. When fire fighters answer a call, the computer will give them important about the burning building, its position and almost all the ways of helping fire fighters with the problems facing them. For example, it can give medical information about invalids living in a burning building. With this information, the fire fighters can take special care to find these sick persons and carry them away quickly and safely.

The Kansas City computer system also keeps a medical record of each of the city’s 9000 fire fighters. The kind of information is especially useful when a hospital can treat the injured. With this information, doctors at the hospital can treat the injured fire fighters more quickly and easily.
