Abstract
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.
Highlights
The forensic investigation activity is led by the Forensic Service within the Criminal Investigation Section of the General Prosecutor's Office, attached to the High Court of Cassation and Justice
At the level of the prosecutor's offices attached to the courts of appeal and the county courts, there are criminalistic offices with tasks in the field of supervision and conducting of their own criminal investigation, as well as generalization of the latest technical-scientific method and means in the criminal investigation activity [1]
The Fire Dynamics Simulator (FDS) software package has been designed, since its conception, to solve practical problems involving the presence of fire in the engineering field of fire protection
Summary
The investigation of a fire event’s causes is a complex activity, implying that members of the investigative team have extensive knowledge about burning of materials, fire thermodynamics, experience, observation, analytical capacity, objectivity, visual and auditory memory. It can be defined as a set of organizational, technical and operative measures and actions, based on specific methods, approaches and means, used in order to precisely establish the sources of initiation, the means of ignition, the circumstances, and, in certain cases, the responsible persons who generated or influenced the event. At the level of the prosecutor's offices attached to the courts of appeal and the county courts, there are criminalistic offices with tasks in the field of supervision and conducting of their own criminal investigation, as well as generalization of the latest technical-scientific method and means in the criminal investigation activity [1]
