In the left foreground are four operators at telephones, one connected with the first aid center, one with the decontamination squads, one with the disaster units and the fourth with the emergency service division. There is a twenty-six watt transmitter and receiver to maintain communcations with units in the field. Two of the operators to the right receive calls and note information for the general public, while one operator handles both incoming and outgoing business calls. This demonstration board was set up at the huge October civilian defense show in Madison Square Garden, New York
