In 2005 two fire fighters were killed during a fire fighting operation in Tübingen in Southern Germany. They were an advance team, who had entered into a burning warehouse with breathing apparatus and a water hose to get to the source of the fire. A burst in the hose cut off their water supply. Flames blocked their way back . Such tragic accidents occur again and again. Most high pressure fire hoses in use survive only a maximum time of 10 s before bursting, if the tube comes into contact with burning material or embers . The goal of a research project funded by the Federal Economics and Technology Ministry (BMWi) as part of its “Central SME Innovation Programme” entitled “Extruded multi-layer flame retardant fire hoses” is to make the hoses more resistant.
