Evaluating the physical demands when using sled-type stair descent devices to evacuate mobility-limited occupants from high-rise buildings
We simulated evacuating people with motor disabilities from high-rise buildings. This study compared 6 sled-type devices designed for stair descent. Surface EMG, heart rate, trunk motion, and perceived exertion data were collected. There are significant differences across devices, particularly on the landings. Two-evacuator devices, did well on biomechanics, evacuation speed, and usability.
