- Abstract
The study of the characteristics of fires or explosions, as well as factors influencing their production and development, leads to the increase of the fire / explosion expertise capacity, the expansion of the knowledge field related to these phenomena, also increasing the health and safety at work. Because of the random evolution, there cannot be two fires the same. A number of factors are involved in the development of a fire: the nature and positioning of combustible materials, the shape and dimensions of the room, the thermal load, the openings to the outside, the location and mode of initiation of fires, etc. Following the similarity of these numerous factors, fire experiments on a natural scale produce very varied results. For the study and experimental determination of the flammability parameters of the different materials and the assessment of the fire behaviour, the following were made: the stand for vertical and horizontal burning determination according to SR EN 60695-11-10, the stand for determination of the ingress efficiency SR 652: 2009. Experimental determinations were performed with these stands. Also, the evolution of the concentration of the most significant gaseous effluents over time has been studied: carbon dioxide, hydrogen cyanide, nitrogen oxides, etc. Different polymeric materials such as polymethylmethacrylate, rubber, melamine was taken in consideration to study the nature and concentration of gaseous effluents. As a result of the combustion of the polymeric materials, high concentrations of gases with high toxicity, namely: carbon dioxide, hydrogen cyanide, nitrogen oxides, and the distribution of these concentrations were determined during the tests. The nature of the resulting gas is dependent on the composition of the burning material, such as for example burning melamine, resulting in significant amounts of hydrogen cyanide.
