(5) Flooring with a slip-resistant surface and provisions to facilitate the free drainage of liquids and that will withstand the forces developed under proof test loadings. Flooring shall have no opening that will allow a sphere of 0.5 in. (13 mm) to pass through.
(6) Means to secure loose items within the platform.
(7) An identification plate shall be located on the platform. The location shall protect against damage and allow easy viewing from both the interior (while hoisted) and exterior (while not hoisted) of the platform. As a minimum, the following information shall be displayed:
(-a) manufacturer name and address
(-b) platform rating in terms of weight and personnel
(-c) platform identification number
(-d) suspension system description for suspended platforms or the intended hoisting equipment manufacturer identification for boom-attached platforms
(-e) weight of the empty platform and its suspension system
(- date of the platform manufacture
(-g) certification of compliance to the design, construction, and testing requirements of this Volume
(-Ii) listing of any unique operational environments for which the platform has been designed
(8) Access systems, if installed, shall be equipped with a positive acting device to restrain the access system from accidental opening. Swinging access gates shall be prevented from swinging outward while the platform is suspended. Access systems and hardware shall meet (b)(2) requirements without detaching or affecting proper operation.
(9) The suspension system shall minimize tipping due to movement of personnel on the platform and should not allow motion of more than 10 deg off the horizontal plane.
(10) For suspended platforms, a suspension system that minimizes the potential for the system’s removal and use for other purposes. The suspension system shall be sized by the platform manufacturer, and its installed sling angle established, so as not to cause damage to the platform. Suspension systems shall comply with the following:
(-a) Rope sling suspension systems with mechanically spliced flemish eyes, if used, shall be designed with thimbles in all eyes. Wire rope clips, wedge sockets, or knots shall not be used.
(-b) Rope sling suspension systems with pored socket end connections, if used, shall be designed in accordance with the manufacturer’s or qualified person’s application instructions.
(-c) Chain sling suspension systems, if used, shall be designed using a minimum of grade 80 chain.
(-I) Shackles, if used in the suspension system, shall be of a bolt type with cotter pin.
(11) Overhead protection, when provided for a platform, shall allow for a clear view of the hoist equipment components directly overhead, from any position in the platform. Any openings designed in the overhead protection shall not allow a sphere of greater than 0.5 in. (13 mm) to pass through.
(12) Include appropriate accessories to facilitate the use of the platform in the special environments specified by the manufacturer.
(13) Welds used in the construction of the platform shall be in accordance with American Welding Society or ASME guidelines.
(14) Bolted connections of load sustaining members or components of the platform shall be in accordance with the AISC Specification for Structural Joints Using ASTM A325 or A490 Bolts.
(15) The incorporation of a weatherproof compartment suitable for storage of the Operator Manual and assorted other documents, or a weatherproof placard displaying the Operator Manual, and readable from the platform, when motion controls that are operational from the platform are installed.
(16) Motion controls, if installed on the platform, shall
(-a) be clearly identified as to their function
(-b) be protected from inadvertent actuation
(-c) be inside the platform and readily accessible to the operator
(-d) when possible be oriented and move in the approximate direction of the function that they control
(-e) return to their neutral position and stop all motion when released
(17) Boom motion controls, if provided, shall additionally
(-a) include a control that must be continuously activated for controls to be operational
(-b) include an Emergency Stop Control that does not require continuous actuation for a stop condition.
