The review article deals with the current issue of collective protection, including collective protection against contamination. The hypothetical threats to the national territory of contamination from toxic industrial agents from high-risk plants (HR) and radioactive materials are presented. Collective protection against toxic industrial agents was characterized, on the basis of NATO documents. The issue of isolation (sealing) of collective protection facilities was discussed. The physical basis of the penetration of hazardous substances into objects as a function of pressure and temperature changes was presented, including ways to protect objects from the penetration of contaminated air.

Ubiegłoroczna nowelizacja Prawa ochrony środowiska w dużym stopniu dotyczy przepisów nazywanych „prawem emisyjnym”, w tym zagadnień dotyczących pozwoleń emisyjnych. Zmiany są na tyle istotne, że warto zwrócić uwagę na najważniejsze ich elementy.

This study traced a deployed real IT system to enhance occupational safety for a polluted confined space. By incorporating wireless technology, it automatically monitors the status of workers on the site and upon detected anomalous events, managers are notified effectively. The system, with a redefined standard operations process, is running well at one of Formosa Petrochemical Corporation's refineries. Evidence shows that after deployment, the system does enhance the safety level by real-time monitoring the workers and by managing well and controlling the anomalies. Therefore, such technical architecture can be applied to similar scenarios for safety enhancement purposes.

The primary aim of the study was to analyse the non-steady state of filtration for selected electrostatic filter materials designed for use in respiratory protective devices. The obtained results showed that the filtration process in electrostatic filters was dependent in the main on the following factors: type of the filter material, electrostatic field strength of the material, and the charge of the aerosol. To a lesser degree the filtration process depended on the sign of the charge and the relative humidity of the air. A significant correlation was found between the increase in the penetration and the decrease in reathing resistance while the filter was being loaded. The effect of resuspension (tearing off and re-deposition of dust agglomerates inside the filter) on the filtration process very significant. It was also observed that under certain conditions electrostatic filter materials lost their protection properties.
