1. Fire service elevator comprising:
an elevator cage with a cage roof, the cage roof having an exterior surface, the elevator cage being at least partly supported and driven by at least one support in an elevator shaft, the elevator cage having on the cage roof a first region external to the elevator cage facing upward and exposed to the elevator shaft above the elevator cage and a second region external to the elevator cage and facing upward; a spray-inhibiting element covering the second region of the cage roof and positioned to be substantially parallel to the cage roof such that a major surface of the element is in direct contact with the exterior surface of the cage roof, the spray-inhibiting element having a surface structure that substantially allows extinguishing water in the shaft falling on the spray-inhibiting element in event of a fire to penetrate at least partly into the spray-inhibiting element and prevent the extinguishing water from spraying toward the at least one support.
