Subject aims expressed by acquired skills and competences
The aim of the course is to teach students to identify hazards and risks in the place of fire, evaluate their impact on the safety of fire protection units. Based on this evaluation, the student is able to choose the procedure and tactics of intervention. Based on the above evaluations, the student is able to quantify the forces and resources for firefighting and rescue of people, animals and property.

Summary
TThe course describes the procedures of fire extinguishing based on the knowledge of fire parameters and fire dynamics in enclosed spaces of buildings and in the open area. Describes and explains the characteristic hazards and specific requirements associated with fires in specific areas of buildings. The teaching emphasizes the expansion of the student's ability to quantify the mounth of fire brigades in real time in fire site without tabulated values of the recommended intensities of fire extinguisher supply, which are not available in the conditions of the real fire.

Subject syllabus:
1) Repetition - forms of fire development and spread, combustion products, fire parameters, fire timeline, fire fighting (location, liquidation, physical and chemical extinguishing), fire attack (main directions), fire defense (active, passive);
2) Fire survey - survey when driving to the scene of a fire (smoke, color, optical density, diameter); evaluation of buildings - the influence of the construction system and the influence of the structure and amount of fire load, the influence of the environment on the tactics of fire intervention and spread, smoke spread, fire ventilation (air infiltration) before fire extinguishing, heat visibility and the nature of flame burning;
3) Ventilation in case of fire - use of ventilation depending on the stage of fire development, natural ventilation, overpressure ventilation, underpressure ventilation, hydro-ventilation;
4) Fire fighting with water - types of water streams and their physical and technical properties; extinguishing effect; water jet application methods - direct and indirect application, volumetric water extinguishing and 3D applications; Utilization of water jet application depending on fire development, fire attack and fire defense; fire performance and amount of water for extinguishing - equation of fire location; use of high pressure water systems;
5) Extinguishing a fire with foam - characteristics and distribution, light medium heavy foam; extinguishing effect, physical and technical properties during transport to the place of application; extinguishing of polar and non-polar liquids, extinguishing with foam on the surface of the fire, volumetric extinguishing with foam;
6) Extinguishing fire with inert gases and powders - characteristics of use, extinguishing effect and chemical method of extinguishing, safety during application of extinguishing agent; combined extinguishing;
7) Quantification of Forces and Means of Fire - Strategy and Tactics; determination of priority and subsequent tasks for achieving the location and liquidation of the fire (extinguishing, cooling ventilation, rescue of persons and property), requirements for the number of intervenors, phasing of the intervention with regard to the availability of forces and resources;
8) Basement fires, residential fires, soil and attic fires, high-rise buildings fires, use of ventilation - overpressure and underpressure ventilation, natural ventilation; intervention procedure;
9) Fires of technological equipment - types of equipment, fires inside and outside equipment; the influence of fire parameters on the construction of technologies in fire conditions; types of individual events in the event of a flammable substance leak; possibilities of quantification of forces and means - complex conditions for intervention - DZP !!! Using of SHZ and PHZ with regard to fire parameters; intervention procedure;
10) Extinguishing equipment under voltage - protection zones, safe distances; Fires in cable ducts and collectors - division of cable ducts, shafts and collectors, specific requirements for fire safety in a cable duct; intervention procedure;
11) Forest fires and fires in agriculture - division of forest fires by type (underground soil and crown), climatic conditions, specifics - speed of fire spread depending on the species, availability of fire site, form of fire attack, obstacles in the way of fire spread - artificial, natural, creating gaps - conditions, requirements and time requirements - extinguishing fires by aircraft - rules and conditions for use; intervention procedure;
12) bottles fires - division (according to filling pressure, according to construction, according to equipment), distribution of gases in th. bottles (dissolved, compressed, liquefied) reasons for these methods of storage, determination of the surface temperature of the bottle, evacuation of th. bottles - conditions for evacuation (according to temperature and type of gas), method of evacuation; cooling (cooling time), safe distances for SaP; Intervention procedure;
13) Rescue during the fire - rescue of individuals and groups, primary and secondary rescue, difference between rescue and evacuation, sensuality of rescue, places for rescue, protection of rescue group, protection of rescued persons - PPE; internal and external intervention lines
