An existing Hospital building has several 'main' entryways that are through stair towers. There is not anywhere near 10' available in these entryways which are located on landings (maybe 5'x8'). My question is, have you seen walk-off mat being carried on stairs? If we put mat on the stair treads down 5 steps and up 5 steps (so we would have the 10' distance for every travel option), this would work, no?

Has anyone else done this or see any reason this would not work?
