Carbon dioxide (CO2) may have toxic effects at concentrations much lower than the concentration at which its stifling effect of asphyxiant is reflected. In the workplace, the maximum permissible exposure limit of 5000 ppm is permitted on the average. However, there are certain places where the concentration of CO2 in an enclosed room or area may potentially reach extreme and life-threatening levels. Extreme levels of CO2 may lead to death, especially in enclosed spaces, such as in fermentation rooms or in the process of wine production or in breweries. CO2 may have negative effects on health and safety at the workplace. Monitoring and control of CO2 in the working environment is important for the safety and health of employees and is one of the approaches to a healthier environment in the workplace. The use of CO2 sensors to control the ventilation can be an effective measure.
Environmental performance of each product is defined already at the stage of its design - in its pre-production stage. Environmental quality of the product is one of the most important factors of environmental performance of a product. Environmental quality includes a range of criteria that indicate the nature of the product and its environmental impact throughout its life cycle. The comparative analysis method is one of the ways to assess the environmental quality of the product. The article gives a specific example of the assessments carried out on the impact drills (of one specific brand) with different technical parameters.
In the working and outside environment a single factor is never found by itself, rather there are always a number of factors the effects of which can be combined, multiplied and thus adversely affect the human body. Evaluating and assessing health risks at work due to exposure to harmful work factors and the working environment is a challenging and long-term process. Limit values are defined for the categorization of types of work in such a way that it is not foreseeable that, according to current scientific knowledge, they will be detrimental to the health of employees. However, these limit values are set for each factor alone and do not take into account the effect of the combined action of individual factors on the human body. The research aimed at assessing the combined effects of risk factors on human health. The experimental proposal of the assessment focuses on the workplace featuring metalworking machinery and technological equipment. The author paid a significant attention to the risk assessment process and synergistic effects of factors.
The work deals with analysis of different transportation domains in horizontal and vertical meaning. It looks for conformity in approaches and terms. It loans to concept of integral safety, i.e. a tool for ensuring the human security; it covers next engineering areas, for instance dependability management, functional safety, security of cyber-physical systems, technical and physical security, surveillance, occupational safety, safe place, human safety etc. Recent professional approaches of safety management and risk engineering are compared with current trends in transportation. It is clear that advanced professional procedures are needed for planned Smart Cities and Industry 4.0 in transportation domain practice; this work contribute to building the unified experts´ language from various transportation domains.
This paper describes the present state of historical gardens and parks which were founded around domiciles of the gentry in the area of Turiec valley, Slovakia. Almost forty of these manor houses are located in the area. In the past, the park or the ornamental garden was created in the immediate vicinity of these buildings. The current state of their attached historical greenery described in this contribution is based on field investigation. Natural landscape parks have been preserved to the best degree by nobility in Mosovce and Turcianska Stiavnicka which used to belong to the Revay family. The park in the village Zaturcie is partially well preserved. The other parks and gardens were destroyed to a large degree and their existence can be accounted for only by occasional older trees. Some difficulties in conservation or reconstruction of these historical landscapes are described in the presented work as well.
Security situation in the world, in each territory and generally in each asset, continuously changes with time, and therefore, there is formed new safety culture that takes into account actual knowledge and experiences with interdependences among the public assets leading to extreme social crises. With regard to the historical development at present there are lots of management types that differ by aims and by assets that they respect. Consecutively in present human society there are groups that shielded by individual management type aims fight against each other, and at the same time all of them goes on good human existence. The paper deals with the relation between human system safety management and environmental management.
