Abstract

Systems and methods for helping a firefighter to identify locations of victim, routes of egress, and dangerous areas during a fire drill are provided. The system'"'"'s components include a fire jacket, a fire goggle, a communications device with earpiece, a locator, a compass, a temperature sensor, a smoke sensor, a processor and memory. Also provided is a life saving device with locator associated with each of one or more victims. The temperature and smoke sensors are disposed within a building in which the fire drill is to be executed. The memory stores instructions that cause the processor to execute a method that guides a firefighter to a victim and/or exit along the safest and most direct route possible. The route being determined based on feedback from the sensors as well as real-time location data from the locators.

9. The system of claim 8, further comprising a step of detecting whether the current path towards victim is correct using the compassing device during procession along target route.

10. The system of claim 9, further comprising a step of detecting whether the current path towards exit is correct using the compassing device during procession along target route.

11. A system for helping a firefighter to identify dangerous areas, locations of victims, and routes of egress during a fire drill, comprising:

a fire jacket;

a fire goggle attached to the fire jacket;

a communication device with an earpiece attached to the fire jacket;

a first locator attached to the fire jacket;

a compassing device attached to the fire jacket;

a temperature sensing device;

a smoke sensing device;

a life saving device associated with each of one or more victims, wherein the life saving device includes a second locator for locating each of the victims;

a processor associated with the fire jacket; and

memory associated with the fire jacket, which stores instructions to be executed by the processor, the instructions comprising;

detecting that a firefighter has put on the fire jacket and the fire goggle, so that the fire drill is being put into action;

detecting the location of a victim, wherein the detection is based on the life saving device that the victim is wearing;

determining a direct route between the firefighter and the victim;

assessing whether the direct route is dangerous, wherein the assessment is based on;

average temperature of the direct route, as detected by the temperature sensing device that is installed at a point along the direct route; and
