The stretcher is a well-accepted first-aid tool, but not very practical for the narrow turnings and precarious gradients of fire stairs. Moreover, even if some adaptation of the ski patrol toboggan-type stretcher could be worked out, I could not image the typical ambulatory office worker test riding such a prone descent. But there were two extraordinarily valuable ideas hidden in this stretcher application that set goals of performance for me. One, the evacuee’s weight should be carried directly by the stairs, not by human muscle. Two, the device should slide over at least two stair nosings at a time to provide a smooth passage over the stairs. Implied in this thought process was a very important, basic assumption. I was designing a universally usable, adaptable and completely portable evacuation unit requiring no installation. I also accepted evacuation of high-rise buildings as primarily a downward-directed activity. Contact evacchair Private Message:
