Tools for quantitative risk assessment used in praxis are predominantly based on linear transformations. A parallel problem of current risk assessment methods is constant time and imperceptions of variability of threat over the course of time. Two specific cases of causal dependence are domino effect and synergic effect. Risk as an attribute of cau...

... above its boiling point. In spite of the fact that we usually take notice only of the consequences of such events, their mechanisms contain a sequence of events -causal dependence. In case of synergic effect there occurs a permanent structural change. All risk assessment procedures, both deductive and inductive, use causal dependence, shown in Fig. 1. Quantification of risk is necessary for the economic aspect of ...

Occupational safety and health belong to fundamental human rights. This fully applies to the protection of employees and other persons, which operate or are located in facilities for the collection of scrap metal. The founder of the landfill or the employer has an irreplaceable place in the field of protection of persons against the effects of ionizing radiation. Based on the identification and assessment of occupational safety risks in the event of failure to ensure timely detection of an orphan source of ionizing radiation, the operator must assess all risk factors with emphasis on radiation. At the same time, it must take specific regime measures, which would minimize the impact on people and the environment. The article deals with the causes of failure the system of protection against the effects of ionizing radiation. The assessment of these causes is performed using the fault tree analysis method with the application of Boolean equations. The result of solving the problem is the calculation of the failure of the regime protection system in the devices, intended for the collection of scrap metal, caused by human error as a result of intentional or negligent actions of the operator and insufficient training in the areas of control of measuring devices, principles of correct use of detection devices, insufficient visual identification of potentially dangerous objects. The contribution of this paper is in the design of appropriate regime measures eliminating the consequences of non–capturing a source of ionizing radiation.

Fire is defined as an extremely hazardous event, causing a threat to life and health of persons, but also damage to the economic sphere. It has been shown many times that fire can occur anywhere and at any time. In order to minimize the risk of fire manifestations, it is necessary to understand its course. In technical practice, computational models are used to determine the partial manifestations of fire, such as fire spread rate, smoke generation rate in the burning area, formation of toxic burning products, flame height, and others. One of the important characteristics is also the energy balance in the burning area relating to the character of burning material, access of oxygen necessary for exothermic reaction of burning, and reaction of the installed safety devices. In this paper we will point out the fire safety of the building. The FDS (Fire Dynamics Simulator) model is recently used in practice, and its advantage is the possibility to model fire even in large and atypical spaces. The contribution of this paper is the practical application of fire safety of construction using the FDS Model, to reduce the cost of fire safety for the structure being constructed. Attention was paid to evaluating how the heat energy that is released during a fire can be influenced by the installed stable fire-extinguishing equipment, taking into consideration the fire resistance of the building structures.
... It enables appropriate decision making. Being prepared to manage risks involves the ability to identify them, assess them and take appropriate measures [9]. Current trends of Quality Management systems are oriented on looking for the solutions, which prevent the losses by effective and efficient tools. ...
Very important in SMEs is to monitor cost of quality and economic indicators for valuation of cost effectiveness. The main goal of this article is to create classification on cost quality categories in SMEs and to analyze economic quality indicators and their trend during long period. In this article authors use economical and statistical indicators for costs of quality. We use common model PAF, that include prevention costs, evaluation costs, internal failure costs, external failure costs. Total costs, individual simple cost index, cost ratio and cost structure were used. We analyzed data from 50 small enterprises with 10-40 employees with their yearly turnover max 3 mil €. The research sample of enterprises was focused on industrial areas of business such as engineering, metallurgy, automotive industry. We analyzed the quality costs in SMEs by the average value of quality cost in all surveyed enterprises. Results of this research brought labeling of cost of quality in SMEs by model the PAF for 10 categories for various enterprises, what is very important for comparing of results of QMS in SMEs. Based on the reference indicators of the total costs of quality in SMEs we can conclude their drop. Reducing the costs of quality was reflected in particular in reducing the costs of internal and external errors. In assessing the economic efficiency in SMEs plays an important role the overall cost that were increasing in reporting period. Very important result is that the cost of quality did not influenced overall cost. This fact is positive for competitiveness in SMEs because it shows a quality of production and product. Reducing of cost of quality brought improving of product quality; reduced customer’s complaints brought financial savings. The economic efficiency indicator shows a value above e > 1. It means that, despite rising cost enterprises generate revenues that are significantly higher than the input factors of production. Cost effectiveness helps to improve TQM performance.
... However, development of recommendations of justification the choice of block-polyurethanes, which is optimal for these operating conditions, is empirical, and the concept of "composition-structure-properties" is incomplete and contradictory. Considerable amount of researches on block polyurethanes is highly specialized and scattered [Shtompel 2011, Madbouly 2009, Thomas 2018, Rimar 2016, Vojtko 2014, Zaborowski 2007, Straka 2013, 2014, Markulik 2016, Michalik 2014, Janekova 2014, Sebo 2012, Bielousová 2017, Dobránsky 2019, Mačala 2012, Pollák 2018. Therefore, development of scientific basis for the creation of blockpolyurethanes of high wear and abrasion resistance, taking into account the influence of the structural organization parameters of all levels of polymeric material on the properties is an urgent scientific and technical problem and is of great practical importance for usage in industry. ...

... The production organization must eliminate the hazards and threats and, if scientific and technical knowledge is not possible, take measures to limit them and prepare measures to eliminate them. (Markulík et al., 2016;Šolc et al., 2017) Ultimate responsibility for risk management is borne by employers and senior management, but their efforts cannot be successful without the active involvement of employees. Managers have to adopt modern trends in health and safety at work, and must be an example in their activities. ...
Occupational health and safety legislation imposes an obligation on the production organization to regularly and comprehensibly inform employees of the dangers, threats and risks involved. In the paper, we assessed the basic requirements of safety in the wood processing workshop on the forming disc saw. Deficiencies in non-compliance with security regulations were determined from the check list analysis (CLA). The safety assessment was performed using the extended point method, where we determined the value of the risk measure. When working on a saw blade, the risk cannot be accepted and safety precautions have to be proposed. For the production organization, we have proposed remedial measures and a safety card to be considered before working on forming disc saw. All the measures proposed by us were accepted and implemented by the production organization. Applying and observing safety measures can prevent the occurrence of an occupational injury or damage to the health of the worker.
