Summary. This article presents the main hazards that occur in the context of inland navigation and their impact on the vessel. First, characteristics are extracted from the following methods with regard to identifying threats: involving steering gear damage to an inland vessel moving on a straight waterway. Next, a hazard identification model is presented, which is appropriate to a situation involving steering gear damage to an inland vessel moving on a straight fairway.

Single polymer polyester composites were recycled by compression moulding and extrusion. The recycled products were formed into films of 5 cm 2 surface area and about 250 µm thick. The paper has presented the influence of recycled materials on the permeability of gases (O2, CO2, N2) and water vapour through the walls of the produced films. The influence of processing on the gas barrier of thin films was also determined. The results obtained were compared with the properties of commercial materials.
