In another embodiment of the device, the thermal knife is beset with the pyrotechnic heaters. In case of fire the rescued person puts on the lifebelt attached to the housing of the device and leaves the building. The thermal knife heated by electrical current of the batteries or the pyrotechnic heaters burns through the thread fastening the two ribbons, and enables the device housing, and the rescued person with it, to slide between the ribbons with a certain, predetermined speed.
