The Forensic Safety Division is responsible for examinations and research related to accident interpretation based on physical and engineering knowledge and strives to realize substantive evidence by combing through the accident site and utilizing the laboratory to search for the traces and the truth hidden behind destruction, combustion and deformation.
Analysis and research on the ignition point and cause of fire through fire & arson site investigation and examination on the collections from the site
Site investigation of safety accidents such as falling, collapse, explosion, electric shock, etc. and analysis and research on the collections from the site
Analysis and research on traces such as tool marks, weapon marks, fingerprints, footprints, etc., morphological analysis and research on bloodstains
Analysis and research for the cause of accident through examinations on firearms, explosives, and chemical explosions
The Forensic Safety Division consists of a Fire & Arson Research Lab, Safety Research Lab, Trace Research Lab, and Firearm Research Lab. The division is doing its utmost to keep Korea safe.
The Fire & Arson Research Lab performs research on ignition mechanism and combustion type analysis by identifying the point and cause of ignition through analysis on a fire site and examination on collections from the fire site and provides assistance to investigations by examining whether it is a case of arson. The analysis equipment used includes optical microscope, X-ray, FE-SEM, and infrared camera. For more efficient and accurate analysis, the laboratory makes every effort to develop analysis techniques by conducting various research projects and introducing analysis equipment using the latest techniques.
The Safety Research Lab conducts analysis and research for the identification of causes of safety accidents such as structural collapses (e.g., facilities, plants, etc.) and crashes, and investigation on the cause of the disaster. Analysis equipment includes FE-SEM, Spark-Emission Spectrometer, Metallographic Microscope, Advanced Indentation Tester, Universal Tensile Tester, Micro Vickers Hardness Tester, Scanner, etc. In order to cope with advanced accidents, the laboratory makes continuous efforts on development of analysis techniques and preparation of high-tech equipment. The laboratory performs FEM and CFD interpretation for analysis of safety accidents, and Midas Gen & Civil, LS-Dyna program, etc. are used for interpretation of structural collapses.
The Trace Research Lab performs trace analysis and bloodstain pattern analysis. Trace analysis is a field that analyzes morphological trace evidence such as an injury type by a tool, footprint and fingerprint type, and bloodstain pattern, which are found at crime scenes. By analyzing the traces of the crime scene, tools used for the crime, size of footprints, and fingerprint makers are presumed, and coidentity is determined by obtaining the suspected tool, shoes or fingerprints of a suspect, etc.
Bloodstain analysis is a field in which crime scenes are reconstructed by analyzing the pattern, size, and distribution of bloodstains generated at the crime scene, determining the cause of its generation, and presuming the behavior. Crime scene reconstruction theory is applied to reconfigure the scene with the bloodstain pattern, and computer simulation, 3D drawing and behavior expression technique are used. If the bloodstain pattern is analyzed, it is possible to reconstruct the behaviors between a perpetrator and victim, to judge the authenticity of the statements of people involved in a crime, and to presume a perpetrator if the pattern of bloodstain is sufficiently obtained.
The Firearm Research Lab performs analysis on firearms and explosives. The firearm and explosive analysis is divided into identification of features of a gun used for a crime by analysis on the gun shooting trail, determination of the shooting location by analysis on ballistic trajectory, interpretation of the case by site inspection and site reconstruction, determination of the type of explosive, and analysis on the components of explosive. To this end, the laboratory uses analysis equipment such as cutting-edge Forensic Comparison Microscope, Oehler 57 speedometer, FE-SEM and HPLC.
