§ 7.224. Landing guards.
(a) On the ascending side of a manlift, landings shall be provided with a bevel guard or cone meeting the following requirements:
(1) The cone shall make an angle of not less than 45 degrees with the horizontal. An angle of 60° or greater shall be used where ceiling heights permit.
(2) The guard shall extend at least 36 inches outward from the face of the belt, but not beyond the upper surface of the floor above.
(3) The cone shall be made of not less than No. 18 U.S. gage sheet steel or material of equivalent strength or stiffness. The lower ledge shall be rolled to a minimum diameter of 1/2 inch and the interior shall be smooth with no rivets, bolts, or screws protruding.
(b) It should be noted that cones on the down run of the belt serve as fairly effective fire stops and tend to prevent the loss of warm air from lower floors.
