Fire investigation is the process of examining the scene of a fire to determine its origin and cause. Investigators look for physical evidence, such as burn patterns, to understand how the fire started and spread. They may also collect samples and interview witnesses to gather more information. The role of a fire investigator is crucial in preventing future fires and ensuring safety. By identifying potential hazards and understanding fire behavior, they help improve building codes and fire safety regulations. This work often involves collaboration with other professionals, including law enforcement and insurance companies, to provide a comprehensive analysis of the incident.
