The A380's passenger cabin is so elevated that 18 doors are equipped with emergency slides made with special friction material to slow down escaping passengers.
A great deal of evacuation injuries involve abrasions from existing slide materials. The dry, rough surface of the slides actually burns through thin layers of clothing and causes some rather nasty wounds. This is obviously more desirable than remaining in a burning fuselage, but I'd like to see what kind of material they've come up with. Perhaps it's felt-like.
Found some shots of the A380 slide prototypes:
