These were tasked with
- gathering and evaluating critical data concerning imminent dangers
- issuing warnings during a state of defense by sirens and over the radio
- issuing the all-clear-signal with sirens and over the radio
- maintaining a constant flow of information to critical administration and industry operations
The warning offices were only tentative during the 50s and early 60s and mostly located in the communication offices of bigger cities, until
suitable areas had been found to construct special locations with an underground shelter.
These shelters were the same for every warning office: About 35 meters long, 29 meters wide and 16 meters high and a maximum height over ground of 3
meters. The bunker was supposed to protect against a direct impact of explosive bombs of up to 1000kg, close hits of even bigger bombs, incendiary bombs and firestorms, against nucelar, chemical
and biological warfare agents and against the effects of a nuclear detonation in the air up to a pressure of 9 atmospheres (10.000 hPa).
For these bunkers it meant that the bottom floor is 2 meters thick and the walls as well as the roof are 3 meters strong. Each of the bunkers takes
up a space of 16.300 cubic meters. Of these, 11.300 cubic meters are reincorced concrete, only 5.000 cubic meters make up the actual rooms. Every one of the ten warning areas in Western Germany
got their own warning station - including the underground shelter - that was under direct control of the Office for Civil Defense.
The "nerve center" of each warning station was the huge two-floor Operations Room in which numerous communication seats and ABC-Situation as well as
general warning charts were located.
Here, all the relevant data was collected and used to make decisions concerning public warnings and information.
Here, all the communication took place in the direction of the affiliate state or district governments but also to all the data suppliers.
Among these data suppliers were "in-house" services such as the liaison to the NATO's situation rooms and the warning service's measuring points as
well as organizations like the German Meteorological Service and the German Flight Control Office.
In the situation room, the ABC- and air situation was constantly tracked on huge charts. These were first made of paper, later from glass and had a
size of about 5x5 meters.
The draftsmen had to draw from the rear side of the map to guarantee an unimpeded view for the personnel.
On the basis of the collected data, the director of the warning station made decisions concerning the alert status for the population in his warning
area and also about the contents and about the nature of the alarm.
The shelter was designed to be able to operate independently for at least 30 days. In order to achieve this, it was constructed with its own
independent water supply from two deep wells, two emergency generators with a power output of 120 kVA and 30 kVA, climate control and ventilation system with switchable sand and room filters.
There was a kitchen with supply room and cooling room for perparing the meals of the personnel and a sick bay for injured or sick personnel.
Here's the list of rooms to put into the warning station shelter according to the 1962 construction program for the air defense service:
the warning service including the necessary intelligence facilities
the utilities and engineering (climate, generators etc.) and the related supplies
accommodation for a staff of 196 persons (60 men, 136 women), of which are: 16 full-time employees (12 men, 4 women) and 3 shifts, each with a
staff of 60 (16 men, 44 women with seperate sleeping and recreational rooms). In case of defense, the beds for the shift personnel have to be used three times a day (eight-hour shifts).
Reserve beds have do be provided to account for changes in the ratio of men and women in the personnel
the kitchen for shift operation and supply rooms
a sick bay including decontamination rooms
double door systems
sanitary installations, hallways, secondary rooms
All ten warning stations in germany were designed the same way.
