The connection between visual communication and occupational safety and health has a long tradition in Poland. The beginnings are seen in the interwar period, when artists representing the visual arts began to take up socially important topics in their works and create visual materials of an informative and educational nature, e.g. in the form of occupational safety posters. Currently, such materials are being developed, e.g. as a result of the activities of the Central Institute for Labor Protection – National Research Institute and institutions and enterprises cooperating with it. The article attempts to characterize visual tools currently used in activities in the field of shaping pro-safe attitudes towards workplace safety. They play an important role in shaping attitudes towards work safety by providing visual information on workplace safety. The article discusses: occupational safety posters, infographics, photographs, videos and animations.

Noise in workplace environments is still the main risk factor for workers in industrial plants. The use of sound insulation enclosures and soundproof barriers to reduce this risk is not always possible or sufficient. A relatively new solution used to reduce noise are acoustic metamaterials that redirect or absorb the sound wave, and show the highest efficiency at frequencies close to the resonant frequency. They are primarily used for narrowband noise. The article presents the developed numerical models which were used to determine the resonant frequencies. Simulations were performed in two different programs based on finite element method (FEM). The obtained results indicate that the tunnel structure with Helmholtz resonators placed within can suppress the noise in several frequency bands (mid-frequency and high-frequency range) and to a greater extent than tunnel structures without resonators.
