One of the main operational tasks of fire investigation units is to extinguish fires, which is most often achieved
by applying various types of extinguishing agents to the burning material. For firefighting to be effective, it is
essential to use appropriate equipment, including fire hoses through which water or water-based solutions are
transported. Fire hoses must be resistant to mechanical, thermal, and chemical exposures. In particular, they
must withstand abrasion, which can compromise tightness and result in leakage or uncontrolled water jets.
Hose webbing typically has a multilayer structure. The outer (surface) layer is exposed to abrasion from sliding
friction in contact with rough surfaces, sometimes containing abrasive particles. Abrasion against sharp edges
occurs less frequently due to safety features such as fire hose saddles. Pilot laboratory tests were carried out on
the hose webbing of four fire hose models to determine the coefficient of friction and linear wear. Additionally,
observations were made on the wear mechanisms affecting the hose webbing surfaces.
