Pasiūlyta modulinių personalo slėptuvių sistemos įrengimo koncepcija, kurios sudėtinės dalys yra pačios slėptuvės bei tų slėptuvių racionalus išdėstymas ir charakteristikų parinkimas. Slėptuvės darbe vadinamos personalo slėptuvėmis, o tarp saugos specialistų jos dar žinomos kaip lokalios slėptuvės (angl. shelters-in-place). Nustatyta, kad personalo slėptuvių konstrukcijos yra gana gerai pažįstamos pramoninės saugos profesionalams bei jas projektuojančių ir statančių įmonių inžinieriams. Rasta, kad slėptuvių sistemos formavimas, kuriuo siekiama užtikrinti kuo didesnę pavojingo pramonės objekto personalo saugą, iki šiol yra atviras klausimas. Išnagrinėta bendriausia slėptuvių klasifikacija. Aptartos plieninės ir gelžbetoninės modulinės slėptuvės. Trumpai aprašyti matematiniai (optimizavimo) metodai, kuriuos galima būtų taikyti ieškant geriausio slėptuvių išdėstymo. Išnagrinėta, kaip modulinių antžeminių slėptuvių išdėstymo problema galėtų būti sprendžiama naftos rafinerijos atveju.

A concept for the installation of a modular personnel shelter system has been proposed, the components of which are the shelters themselves and the rational arrangement and selection of their characteristics. Shelters are called personnel shelters in the workplace, and among safety specialists they are also known as shelters-in-place. It has been established that the structures of personnel shelters are quite well known to industrial safety professionals and engineers of the companies designing and constructing them. It has been found that the formation of a shelter system, which aims to ensure the greatest possible safety of personnel at a hazardous industrial facility, is still an open question. The most general classification of shelters has been examined. Steel and reinforced concrete modular shelters have been discussed. Mathematical (optimization) methods that could be applied in finding the best arrangement of shelters have been briefly described. It has been examined how the problem of arranging modular ground shelters could be solved in the case of an oil refinery.

Nagrinėjama cilindrinių slėginių indų gaisro sukeltų sprogimų metu susidariusių skeveldrų matmenų vertinimo problema. Dėmesys sutelkiamas į verdančio skysčio ir besiplečiančių garų sprogimus (BLEVE sprogimus). Skeveldrų matmenų vertinimas apima pirminių duomenų gavimą, šių duomenų pateikimą ir (arba) apdorojimą iki Bajeso analizei tinkamos formos ir apdorotos informacijos taikymą prognozuojant indų defragmentaciją BLEVE avarijų metu. Siūloma skeveldrų matmenų vertinimo procedūra pagrįsta ankstesniais darbais, kuriuose buvo sukurtas Bajeso metodas, skirtas cilindrinių indų irimo schemoms prognozuoti. Šiame tyrime siūlomi algoritmai, skirti duomenims apie skeveldrų matmenis rinkti ir apdoroti. Algoritmai remiasi trijų indų skilimo schemų, kurios vyrauja indų sprogimų statistikoje, egzistavimu. Tokio irimo metu susidaro raketos pavidalo fragmentai, vadinami pailgaisiais antgaliais. Šios skeveldros laikomos pavojingiausiais indų irimo produktais. Skeveldrų matmenų vertinimas apsiriboja pailgųjų antgalių ilgio nustatymu Šio tyrimo rezultatai parengti siekiant geriau įvertinti ir sumažinti riziką, kurią kelia galimas skeveldrų, susidariusių gaisro sukeltų indų sprogimų, poveikis.

The problem of assessing dimensions of fragments generated by fire-induced explosions of cylindrical pressure vessels is considered. The attention is focussed on boiling liquid expanding vapour explosions (BLEVEs). Assessing fragment dimensions comprises acquisition of raw data, bringing/processing this data to the form suitable for a Bayesian analysis and application of processed information to predicting fragmentation of vessels in future BLEVE accidents. The proposed procedure of assessing fragment dimensions is based on our previous work, in which a Bayesian approach to predicting fragmentation/failure patterns of cylindrical vessels has been developed. Algorithms suggested in the present study for collecting and processing data on fragment dimensions are conditioned by an existence of three fragmentation patterns that prevail in the statistics of vessel ruptures and produce rocket-like fragments known as oblong end-caps. These fragments are viewed as the most dangerous products of vessel ruptures. Assessing fragment dimensions is reduced to dealing with the length of the oblong end-caps. The results of this study were developed to better assess and reduce the risks posed by potential exposure to fragments generated by fire-induced container explosions.

The problem of the impact of high temperatures, technological processes, and environmental conditions on steel building structures protected by fireproof coatings is examined. The focus is on passive fire protection coatings used in different, often aggressive environmental conditions, and changes in their fire resistance properties. The assessment of the effectiveness of fire protection coatings includes a theoretical analysis of the behavior of steel structures during a fire, a classification of the protective measures used, and an evaluation of the test results. The study examines different intumescent coatings, with and without additional protection against environmental influences. Fire resistance is assessed by standard tests, with the temperature raised according to the curve specified in standard LST ISO 834:1997. Changes in the condition of the samples after long-term exposure in a production environment, i.e., damage to their coatings, are analyzed. The results of the study are intended to justify the rational selection of fire-resistant coatings and the assessment of their operating conditions when designing steel structures.

Thesis abstract (LT)
Gaisrų gesinimas ir ekstremaliųjų situacijų valdymas yra kritiškai svarbūs visuomenės saugumo užtikrinimo aspektai. Nagrinėjama problema siekiama išanalizuoti ne sudėtingus, bet lokalius incidentus ir reagavimą į juos. Tyrimo aktualumą pagrindžia ne tik poreikis integruoti tradicines gaisrų gesinimo praktikas į pasirengimą, bet ir būtinybė ieškoti optimalių sprendimų dėl žūstančių žmonių gaisruose mažinimo. Magistro darbas sudarytas iš trijų pagrindinių dalių: pirmoje dalyje trumpai apžvelgiamas Europos Sąjungos ir Lietuvos teisinis reguliavimas pasirengimo likviduoti įvykius srityje; antroje dalyje pateikiama geroji užsienio šalių gaisrų gesinimo praktika, reikalaujanti kompleksinio, daugialypio požiūrio, apimančio ne tik techninius aspektus, bet ir gilinantis į psichologinius bei socialinius pasirengimo veiksnius; trečioje dalyje ypatingas dėmesys skiriamas gaisrų, kuriuose žuvo žmonės, išsamiai analizei. Atskleidžiama, kad ne vien tik priešgaisrinių gelbėjimo pajėgų reagavimo laikas lemia gaisrų baigtį. Socialiniai ir demografiniai veiksniai, ypač ryškūs kaimo vietovėse, taip pat vaidina esminį vaidmenį formuojant gaisrų prevencijos ir gelbėjimo operacijų efektyvumą. Analizuojant I-II pajėgų išsiuntimo numerio įvykius atskleista, kad dauguma gaisrų apima individualius namus ir juose dėl neatsargumo sukeltas nelaimes. Šis tyrimas parodė, kad tokio tipo įvykiai sudaro didžiausią dalį išvykimų, kuriuose įgyta patirtis, priimti sprendimai gali būti tikslingai panaudoti tolesniam mokymuisi ir pasirengimui likviduoti didesnius įvykius. Darbą sudaro – 71 p. teksto, 24 pav., 3 lent., 85 literatūros šaltiniai.

Firefighting and emergency management are critically important aspects of ensuring public safety. The problem under investigation aims to analyze not complex but local incidents and responses to them. The relevance of the study is justified not only by the need to integrate traditional firefighting practices into preparedness but also by the necessity to seek optimal solutions for reducing fatalities in fires. The master's thesis consists of three main parts: the first part briefly reviews the legal regulations of the European Union and Lithuania in the field of preparedness for emergency response; the second part presents good practices of firefighting from foreign countries, requiring a comprehensive, multi-faceted approach that encompasses not only technical aspects but also delves into psychological and social preparedness factors; the third part focuses on a detailed analysis of fires resulting in fatalities. It reveals that not only the response time of firefighting rescue forces determines the outcome of fires. Social and demographic factors, particularly pronounced in rural areas, also play a crucial role in shaping the effectiveness of fire prevention and rescue operations. Analyzing incidents involving the dispatch of first and second response units revealed that most fires involve individual homes and are caused by negligence. This study demonstrated that such incidents constitute the majority of call-outs, and the experiences gained and decisions made can be purposefully utilized for further training and preparedness for larger events. The work consists of 71 pages of text, 24 figures, 3 tables, and 85 references.

Baigiamajame magistro darbe nagrinėjamas stiklo dumblo poveikis betono savybėms. Betono mišiniams gaminti buvo naudojami cementas, smėlis, skalda, superplastiklis, vanduo, stiklo dumblas. Darbo metu buvo formuojami betono mišiniai su skirtingais stiklo dumblo kiekiais. Stiklo dumblu buvo keičiamas cementas – 0 %, 5 %, 10 %, 15%, 20 %, 25 % bei 30 % betono mišinyje. Darbe tirtas stiklo dumblo poveikis šioms modifikuoto betono savybėms: tankiui, gniuždymo ir lenkimo stipriui, ultragarso impulso sklidimo greičiui, taip pat nustatytas atsparumas šarminei korozija pagal ilgio ir svorio pokyčius. Iš atliktų tyrimų rezultatų galime teigti, kad stiklo dumblas gali būti naudojamas, – kaip cemento pakaitalas betono mišiniuose, taip bus sumažinamas cemento kiekis betonuose ir utilizuojamas stiklo dumblas. Betone iki 10 % cemento keičiant stiklo dumblu, galima gaminti modifikuotus betonus, kurie bus atsparesni šarminei korozijai.

The final master's thesis examines the effect of glass sludge on concrete properties. Cement, sand, aggregate, superplasticizer, water, and glass sludge were used to produce the concrete mixtures. During the work, concrete mixtures with different amounts of glass sludge were formed. The cement was replaced with glass sludge in the following proportions: 0%, 5%, 10%, 15%, 20%, 25%, and 30% in the concrete mixture. The thesis investigated the effect of glass sludge on the following properties of the modified concrete: density, compressive and flexural strength, ultrasonic pulse velocity, as well as the resistance to alkali-silica reaction based on changes in length and weight. From the results of the conducted research, we can state that glass sludge can be used as a cement replacement in concrete mixtures, which will reduce the amount of cement in concrete and allow for the utilization of glass sludge. In concrete where up to 10% of the cement is replaced with glass sludge, it is possible to produce modified concretes that will be more resistant to alkali-silica reaction. The thesis consists of 6 parts: introduction, literature review, methodology, experimental part, conclusions, and list of references. The scope of the thesis is 54 pages of text excluding appendices, 25 figures, 8 tables, and 61

Thesis abstract (EN)
The bachelor's thesis examines fire safety aspects related to the storage and recycling of wood waste. Based on scientific literature, statistical data, and fire dynamics simulations using the FDS software, the main causes of fire risks and potential consequences are assessed. The third part of the thesis presents eight different simulation scenarios that analyze how the size, shape, and distance of wood waste piles from the building affect the temperature distribution and heat release rate. The obtained results enabled the formulation of practical recommendations aimed at reducing hazards and ensuring safer wood waste management. The thesis consists of 5 parts: introduction, 3 main chapters, conclusions, list of references and appendices. Thesis consists of: 50 p. text without appendixes, 22 pictures, 7 tables, 41 references and 1 appendix.
