Measurability effectiveness of crisis management is a complicated matter. Its necessity is determined defense resources spent on prevention, education and rescue equipment components. Contribution indicates the direction and the way it could move in a serious effort and calculation efficiency systems and their comparison between countries. Paper is focused on objectivity of measurement in general as a result of own reflections towards this topic.

The work is focused on an experimental test of temperature development in a scale model. Various types of combustible materials were used in the test in combination with the spruce wood. The work points to the influence of the fuel source on selected parameters of a fire in an enclosed space. The course of a fire is influenced by various factors. The course of a fire in an enclosed space differs from the course of a fire in an open space. As a part of the overall development of the fire, the temperature of the fire is affected. Therefore, one can state that the parameters affecting the development of an internal fire also have a direct effect on the temperature development. The main goal of this work is to compare different types of materials in terms of the properties they manifest during a fire. The practical part contains the analysis of the materials used in the experiment. Description of the scale model and of the measuring control panel are the content of another part of the work. In the end there is a comparison of the individual temperature curves.

Current software systems address modelling and simulation of fire in various environments and conditions. They allow you to test various fire scenarios and model their course and consequences. They are able to detect the possible risks and circumstances that can lead to the damage and to prevent or limit the consequences of potential future fires. Based on fire tests and experiments, new tools and means have been developed to gather the necessary information on fires. Such a means is computer fire simulation. They are based on empirical and scientific knowledge and are comparable to real fire experiments. The great advantage of fire simulations is the non-destructiveness of materials and greater flexibility of use. The complexity of spatial geometry, the mathematical difficulty of solving differential equations, and the demands on computer performance, often include the complexities of fire modelling, but simulation currently allows fairly accurate prediction of the spread of fire and has become an important part of improving fire safety. Fundamental programs such as FDS, Smokeview and Smartfire are introduced as well as flood simulator developed in Czech Republic.

RM/RA CRAMM is a comprehensive risk assessment methodology for crisis management, which consists of identifying, analysing and assessing risks. Quantitative outputs serve as a basis for identifying risk management priorities, preparing preventive measures and responding to identified facts. The methodology is applicable to a wide range of risk types, natural risks, including fire risks, technology risks, criminal risks and other risks of a social nature. The RM/RA CRAMM methodology provides the basis for determining the real state of a given territory, allowing it to sort individual risks according to priorities. Risk assessment is the starting point for the reaction phase. By reacting, we mean preventive measures, including the allocation of Police units, Integrated rescue system units, their training, technical equipment and population awareness. The RM/RA CRAMM methodology provides the basis for determining the real situation in the given territory, allowing the individual risks to be sorted according to the priorities. Risk assessment is the starting point for the reaction phase.

The paper deals with the leakage of nitric acid in road transport (ADR); its specifications, problems and complications during its leakage from the tank into the environment. The first part describes specific characteristics and their means of transport. Following part discusses the experimental investigation of the specific characteristics of HNO3 . The experiments on reaction of nitric acid in contact with diesel, gasoline, valvoline engine oil and coolant as well as with samples of common vehicle’s materials such as iron, aluminium, copper, tire rubber, ABS plastic and asphalt. Reactions observed not always met the expectations of strong reactions as described in Security data sheet. The third part describes a possible ways of acid leakage from the tank and its disposal. Recommendation concerning effective action of Fire units are described in order to stop the leaking and minimize the damage caused by nitric acid.

This paper deals with the intervention activities of voluntary fire brigades in municipalities in cooperation with professional fire brigades. It emphasizes the need of the voluntary fire activities their awareness towards dangerous situations. There are many risks sometimes underestimated during the fire attack or other fire brigade activities. Respecting the basic rules of work prevents the injuries and fatalities. The paper focus on most often dangerous situation and bad habits of the volunteers which are very risky in the sense of health safety. The paper states the types of interventions defined and the requirements for the necessary equipment. List of selected risks for intervening fire fighters and their causes is written. The last part describes firefighter injuries caused by their fault in sense of ignoring basic Health & Safety rules.

Detecting the causes of fires is one of the major and complex technical disciplines in the context of activities related to the Fire Protection Department. The fulfilment of this task cannot be understood in a static way, but rather as a constantly evolving process where it is absolutely necessary to use the results of science and technology and to apply the new knowledge effectively in practice. Arson is a very costly, socially dangerous problem. The amount of fire damage in 2015 was in the Slovak Republic, with the statistically reported average number of exits to fires over the last 10 years reaching 11500. In 2015, it was 11317 fires, which were intercepted by fire and fire brigade firefighters. Most fires have arisen from the carelessness and neglect of adults, which caused up to 53% of all fires last year. The second most significant group of causes of fires is of utmost interest from the point of view of the causes of fires. The share of deliberate fires was 13% in 2015, i.e. 1471 fires. An additional 10% of fires originated from unknown causes. The paper deals with fire investigation procedures and focus on procedures of sample collecting with use of arson dogs or alternative technic sample equipment.

The paper deals with the problematic of small-scale fire tests, its preparation phase and fire experiments connected to Flashover phenomena. Real 3D experiments in small-scale need to be prepared in sense of exactness by exact calculations including mathematic πnon-dimensional groups in order to make a functional small-scale model representing the full scale modelling in the effective way. The interior represented by the cribs made mostly of wood, polymer and other materials common in rooms or offices need to be prepared in sense of their amount, position and porosity. After that the construction of the small-scale model can be started with respect to all the dimensions, amount and proportion of material calculations.
