Fire means beside direct (financial)damage often far more indirect costs caused by interruption of operations and loss in sales, market share, property and,in the worst case people can get injured or even get killed (on average around80 persons a year). Fire in buildings is clearly a disaster and for this reason,fire prevention and fire protection must be given top priority in building design.Prevention consists of a combination of different measures meant to protectprimarily the occupants of a building and to prevent damage to adjacent buildings as well as the environment. It is important to be aware that the fire-safety chain of the different fire prevention and protection measures is only as strong asits weakest link.
