Fire investigation is the process of determining the origin and cause of a fire. Investigators examine the scene, looking for evidence such as burn patterns, materials involved, and any potential ignition sources. This helps to understand how the fire started and spread, which is crucial for preventing future incidents. The role of a fire investigator often involves collaboration with other professionals, including firefighters, law enforcement, and insurance adjusters. They may also use specialized tools and techniques, such as thermal imaging cameras and chemical analysis, to gather information and support their findings in legal or insurance matters.
