Determination of surfactants in fire extinguishing devices
Janebová, Bibiana ; Zlámalová Gargošová, Helena (referee) ; Vávrová, Milada (advisor)
Nowadays are foam concentrates used as the primary extinguishing agent for flammable liquid fires (especially hydrocarbons), means of transports fires, the release of chemical substances in environmental accidents, and their importance is still growing with the industrial development. All units of fire protection have foam concentrates in their equipment, so it is important that firefighters to have some necessary knowledge about their characteristics and to be able to use them effectively and safely for the environment. The basic component of foaming concentrates are surfactants. This diploma thesis analyzes foam samples which are commonly used, by methods for analysis of drinking, surface and wastewater and determines cationic, anionic and nonionic surfactants.
Toxicity Assessment of Firewaters
Rybková, Tereza ; Ličbinský, Roman (referee) ; Adamec, Vladimír (advisor)
The issue of toxic extinguishing water is currently getting more to the fore. When a fire arises a wide range of hazardous substances that may negatively affect the quality of some components of the environment. A significant problem can be then extinguishing water runoff into sewers or some components of the environment. The objective is to assess the ecotoxicological properties of extinguishing water, determine the toxicity of the extinguishing water by experiments and thus contribute to the deepening of knowledge in so very few solved problems.
Impact assessment of ordinarily used firefighting agents on selected environmental compartments
Jabandžievová, Barbora ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
This diploma thesis is focused on the evaluation of effects of the most frequently used extinguishing agents in the South Moravian region on selected aquatic and terrestrial organisms. Extinguishing substances which have been tested are foaming agents Sthamex and Moussol, rigid wetting agent TS ECO and TS Turbo and ABC FAVORIT fire - extinguishing powder. Their effects have been tested on aquatic organisms Daphnia magna and Scenedesmus subspicatus and terrestric organisms such as Folsomia candida, Lactuca sativa, and Eisenia fetida. Validation test on standard substances have been performed to verify the validity of the test results. From the obtained results values of IC50, LC50 and EC50 were calculated, through which the impact of individual extinguishing agents on the components of the environment was assessed.
