In order to verify the restorability of all damages suffered, careful analysis of the contractual conditions of insurance policies is carried out, with the help of lawyers and attorneys specializing in insurance and damage compensation, in synergy with the expert fire surveyor. This investigative activity includes the thorough examination of locations and their documentation through video, photographic and infrared filming with the help of thermal imaging cameras, drones and other instrumentation. In addition, samples are collected for later analysis in the laboratory using advanced technology. All fire investigation operations must be carried out as promptly as possible by accessing the scene of the accident before it undergoes any changes. Although expert witnesses can start the investigation at any time based on documentation collected by other actors such as the fire department or law enforcement, it is still advisable to take action as soon as possible.
