Introduction to Fire Investigation
Fire investigators conduct their investigations using a systematic approach utilizing the scientific method, including the following: When arsonists attack, there is very rarely much evidence left at the scene. However, arsonists usually use accelerants to speed up a blaze. Forensic scientists use technologies to heat samples taken from the scene causing any residue to separate. This sample is then analyzed to determine the chemical structure. Scientists also use other tests such as using liquid nitrogen gas to trap residue which are then analyzed using gas chromatography. The investigator receives the assignment and responsibilities
- Plans the investigation and assembles tools, equipment, and personnel
- Examines the scene and collects data
- Collects, tests, evaluates and documents evidence
- Applies the scientific method to analyze the information obtained
