    Opis:
    Operating experience from different types of industrial installations has shown that combinations of different types of different hazards occur during the entire lifetime of the installations. Typically site specific occurring hazards cause or induce other hazards to occur. In particular, natural hazards rarely happen alone. Thus, it is very important to note that almost any event combination of hazards is possible and that it is necessary to identify these interactions and find ways to mitigate the effects of hazard combinations. Therefore, it is a basic task to investigate and assess the relevant combination of hazards not only for a single installation but for the respective site/industrial park. In that context domino effects and cascade effects pose particular challenges for risk management to prevent industrial accidents.

    Opis:
    The article presents the results of measurements of environmental noise caused by devices operating in the surface facilities of hard coal mines and by the technological processes related to the loading and transport of spoil and materials necessary for production. The research results are part of the program “Consequences of excessive noise in the mining environment of hard coal mines”, the overarching goal of which is to reduce the emission of industrial noise. A sampling method was used to determine the actual values of noise levels emitted to the external environment from mines and mining plants as well as to identify the acoustic power levels of devices and processes constituting the main sources of noise in mines. The results showed that mines and mining plants are often not fully aware of the scale of the environmental impact of the undesirable noise they emit. Therefore, the current periodic measurements of environmental noise should be replaced with permanent monitoring, which will be beneficial not only for the environment and residents of housing estates located near mines but also for the mining plants themselves.

    Opis:
    This paper presents an analytic procedure to assist safety practitioners in evaluating the audibility of an existing auditory warning system in their workplaces. Two alarm location models are described: (a) a model with an unknown signal sound level, and (b) a model with a known signal sound level. A heuristic algorithm to determine a minimum number of alarm devices and their locations so that the warning signals can be clearly heard by workers is also proposed. The algorithm considers the ambient noise level, noise levels generated by individual machines, locations where workers are likely to be present, and noise levels at worker locations. From the numerical examples and the computation experiment, both the optimization and heuristic approaches yield solutions that satisfy the 15-dBA constraints. The heuristic approach is efficient in solving large alarm location problems due its capability to find near-optimal solutions within reasonable computation time.
