Every year, approximately 100 people die in fire related incidents in Sweden. ”Seek” is designed to assist fire fighters to locate people faster in smoke diving procedures. ”Seek” identifies people and possible dangers within the building before the smoke diving procedure begins. This allows the operation to be streamlined and planned, as well as avoiding risks which fire fighters are exposed to today. The early overview created by the ”Seek” smoke detector not only saves time in planning but reduces the time from accident until the people in the burning building can receive skilled care, increasing their chance of survival.
