(2) In lieu of the fixed guards specified in Section 3097(d)(1), floating type safety cones may be used. Such floating cones are to be mounted on hinges at least 6 inches below the underside of the floor and so constructed as to actuate a limit switch should a force of 2 pounds be applied on the edge of the cone closest to the hinge. The depth of this floating cone need not exceed 12 inches.
(e) Protection of Entrances and Exits to Steps.
(1)
The entrance and exit to the manlift shall be arranged so the landing area extends not less than 2 feet nor more than 3 feet from the edge of the floor opening to the runway enclosure, measured perpendicular to the plane of the manlift belt. Where the enclosure is more than 3 feet from the edge of the floor opening, or where the enclosure is not required by Section 3097(a), the following additional guards shall be required:
(A) A standard guardrail located so the landing area extends not less than 2 feet nor more than 3 feet from the edge of the floor opening to the guardrail, measured perpendicular to the plane of the belt and
(B) Standard guardrails parallel to the side guards required by Section 3097(f) and forming, with the side guards, a maze type entrance to the landing area of the manlift.
(2)
Additional guardrails or partitions shall be required whenever arrangements are such that the loading and unloading can be done from the side of the manlift step or when access to the landing area or floor opening is direct rather than by a definite guided indirect route.
(3) The combination of side guards, enclosures, and guardrails shall be arranged to minimize the hazard of debris or materials falling down the runway for the mainlift.
(f) Side Guards for Openings.
(1) In order to preclude side loading, the floor opening at each landing shall be guarded on the open sides by panels of not less than No. 13 M.S. gage flattened expanded metal to reject a 1-inch ball in a frame of angle iron or pipe.
(2) The side guard shall be not less than 6 feet high and of a length so that the end posts are located at least to the ends of the manlift step but not more than 4 inches beyond the step.
(3) The side guards shall be located not more than 4 inches from the sides of the floor openings.
(4) Both ends of the side guards shall be equipped with a handle projecting approximately 4 inches from the end post in the direction away from the plane of the belt. The handle shall have closed ends rounded to the end post of the side guard and shall extend from approximately 3 feet to 5 1/2 feet above the floor.
(5) The top ends of the side guards shall be rounded where the top and end posts meet.
(g) Bottom Arrangement.
