Performance of Thermal Exposure Sensors in Personal Alert Safety (PASS) Devices (NISTIR 7294)

Fire fighters can be overcome by heat or smoke of a fire and may be unable to alert other fire ground personnel to their need for assistance. Personal Alert Safety System (PASS) devices are designed to signal for aid if a fire fighter becomes incapacitated. Thermal exposure sensor technology has already been included in a number of PASS devices, but no standard exists for testing the performance of the thermal sensor. A series of static oven, flow loop, and full-scale experiments were conducted to demonstrate the performance of different PASS devices. This experimental data was used to develop a prototype standard test protocol which can used to quantify the thermal sensor performance.
