Analysis Service

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.

  • Fire·Arson

    Analysis and research on the ignition point and cause of fire through fire & arson site investigation and examination on the collections from the site

  • Safety Accident

    Site investigation of safety accidents such as falling, collapse, explosion, electric shock, etc. and analysis and research on the collections from the site

  • Trace

    Analysis and research on traces such as tool marks, weapon marks, fingerprints, footprints, etc., morphological analysis and research on bloodstains

  • Firearms

    Analysis and research for the cause of accident through examinations on firearms, explosives, and chemical explosions

Introduction of Laboratory

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.

01 Fire & Arson Research Lab

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.

  • Fire Site Investigation
  • Optical Microscope Examination
  • FE-SEM Analysis
  • X-ray Examination
02 Safety Research Lab

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.

  • Site Inspection for Collapse Accident
  • Interpretation of Collapsed Structure
  • Reproduction of Collapse Accident
  • Collapse Testing
  • Container Explosion Test
  • Fracture Surface Test
  • Defective Factor Inspection
  • Reconstruction of Tunnel Collapse
  • Reconstruction of Crane Accident
  • Motion Picture Test
  • Impact Test
03 Trace Research Lab

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.

  • Various tools and weapons
    commonly used in crime scenes
  • Determination of coidentity
    between the cut face of a copper
    cable and the cutter
  • Analysis on coidentity of the
    trace on a can lid damaged by
    a flat screwdriver (Comparison Microscope)
  • A cut face of a copper cable
    analyzed by 3D microscope
    (Infinite Focus Microscope)

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 pattern of impact spatter
    bloodstain generated when
    a victim's bleeding part is hit again
    by the crime tool
  • Simulation result applied to 3D
    drawing for presuming the
    bleeding site of impact spatter
  • Deviating bloodstain pattern by
    brandishing generated when a
    knife with bloodstain was
  • 3D drawing and behavioral
    patterns shown by reconstructing
    the site with bloodstain pattern
04 Firearm Research Lab

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.

  • Forensic Comparison
  • Investigation on the
    explosion accident of the
    turret of a prototype tank
    for export
  • Comparison of the trace of
    attack by a comparison microscope
    (Left: An empty shall of
    the suspected gun;
    Right: An empty shell collected
    at the site)
  • Site investigation of
    explosive blast accident
    (Explosion accident at
    Daejeon antitank propellant
    manufacturing room)
