Due to the smoke development, the fire department warned the population in the wider area – up to Frankfurt and the airport about 30 kilometers away. Windows and doors should be closed and ventilation systems shut down. Preliminary checks have so far found no hazardous substances; the intensity of the fire has already been reduced.
The research center described the situation as dramatic. There were initially no concrete details about the extent of the damage. The fire department anticipated an operation that would last at least until the late evening hours.
