Fire protection in historic monuments and buildings is often a point of contention in practice, as heritage conservation cannot accept all measures required from a fire safety perspective. However, the existing conditions, the structural state, and especially the intended use of the monument necessitate these preventive fire protection measures. Fire protection is particularly important in historic buildings, as cultural assets damaged by fire, soot, and extinguishing water can be permanently destroyed and never restored to their original state. It is typical for historic buildings that their original structure favors the onset of fire and, above all, the spread of fire, making rescue and firefighting efforts more difficult. The fire department often has limited opportunities, as successful extinguishing, rescue, and recovery operations are only possible under certain conditions.
