“…La variabilité de la composition chimique finale des produits pétroliers prend source dans la composition chimique initiale du type de pétrole brut à partir duquel ces produits ont été raffinés (Roussel et Boulet, 1994 (Roussel et Boulet, 1994). Lentini (2006) définit trois niveaux de contrôle sur la composition chimique finale des produits pétroliers. Le premier est associé à l'origine du pétrole brut comme exposé au point précédent.…”

“…Les caractéristiques de source du réseau de distribution sont directement corrélées à la structure du marché pétrolier qui est extrêmement complexe. Lentini (2006) définit ces caractéristiques comme le troisième point de contrôle de la variabilité de la composition de l'essence. Les caractéristiques associées au réseau de distribution se produisent essentiellement suite à la sortie des produits (semi-)finis de la raffinerie.…”

“…Where fire causes cannot be determined directly, due to factors such as special or unclear technical reasons, the magnitude of the event, the need for laboratory tests and technical-scientific expertise, or at the request of the criminal investigation authorities or other people involved, it is necessary to investigate the probable causes of fire [2,3].…”

Investigating the fire type events is characterized by a high degree of complexity, due to the fact that it has to find answers to aspects coming from multidisciplinary fields: technical-scientific, legal, organizational, psychological, etc. The management of the findings, the analyzed samples, and the resulting data implies a series of complex activities, based on the use of advanced procedures and techniques. Fire investigation aims to determine the source of ignition and all the components that contribute to define the cause of the fire, to assess the motivations of the involved persons and to decipher the mechanism of heat transfer or burning processes that describes the propagation and development of a fire. Often, in order to understand the mechanism of the pyrogenic phenomenon, the following approaches are used in the current practice: technical-scientific expertises, reconstruction of the event on the field or in the laboratory, sample analysis, and, last but not least, computer simulations. This paper aims to highlight the role of the numerical models used in the field of fire safety, respectively in the elaboration of the post-event, technical-scientific expertises, by presenting some results obtained from the computer simulations, used to substantiate the fire mechanism and to formulate the conclusions.

“…In the case of legal disputes, requirements of rigorous proof based on scientific methods are more and more frequent, which implies that the evidence found at fire sites must be analyzed correctly and the data interpreted accurately . To properly identify the origin and cause of the fires, the fire investigators need to collect all the related trace evidences and perform comprehensive scientific analysis.…”

Summary Among the common materials, metals can be hardly destroyed by flame or the heat emanating from a normal fire. Consequently, investigation on the thermal patterns produced on metallic objects after fire exposure can provide important physical evidence for fire cause/origin determination. Aluminum alloy is widely used in our daily life and the industry; hence, it can be easily found on a domestic or industrial fire scene. In this paper, the aluminum alloy 5052 was exposed in the simulated combustion gases with and without kerosene in the range of 300 to 500°C. Mass change, morphologies, and microstructures of each sample were carefully characterized by thermogravimetric analysis, morphologic observation, and electron microscopy observation with energy‐dispersive spectroscopy analysis after exposure. As expected, the microstructure of alloy changed during high temperature exposure. At the same time, an oxide scale formed and was thickened on the surface of alloy. The results reveal that the temperature can significantly affect the growth of oxide scale and the metallurgical microstructure of alloy. It is noteworthy that the presence of kerosene in the combustion gas accelerated oxidation rate and produced oxide scales different from those formed in air. These feature evolutions in surface oxide are expected to offer complementary insight on determining the fire characteristics, such as the exposure temperature, period and whether liquid accelerant is involved.
