5.11.4 All types of dockboards shall have a highfriction surface designed to reduce the possibility ofemployees or rough terrain forklift trucks slipping.5.11.5 All types of dockboards shall be designedand maintained so that the end edges will have asubstantial contact with the dock (or loading platform)and the transport vehicle to prevent the dockboard fromrocking or sliding.
5.12 Rough Terrain Forklift Trucks and Railroad Cars
5.12.1 When rough terrain forklift trucks are drivenon and off road trucks or trailers during the loadingand unloading operation, the brakes on the road trucksand trailers shail be applied and wheel chock(s),orpositive mechanical restraints which provide the equiva-lent protection of wheel chocks，shall be engaged.
5.12.2 Provision shall be made to prevent railroadcars from being moved during loading and unloading.Wheel stops,hand brakes，or other recognized positivemeans shail be used to prevent movement during loadingand unloading.

5.12.4 Maintain a safe distance from the edge of[ anps，plalfornas,or other similar working surfaces.
5.12.5 Do not move railroad cars or trailers with arough terrain forklift truck unless the truck is properlydesigned and equipped for that operation.
5.13 Warning Device
5.13.1 Every rough terrain forklift truck shall beequipped withan operator-controlled horn，whistle,gong, or other sound-producing device(s). The usershall see that all warning devices are in place and inworking order.
5.13.2 The user shall determine if operating condi-tions require the rough terrain forklifttruck to beequipped with additional sound-producing or visualdevices. and be responsible for providing and main-taining such devices.
5.14 Relocating Rough Terrain Forklift Truckswhen utilizing lifting equipment such as elevalors,cranes，ship hoisting gear，etc.,to relocate a roughterrain forklifttruck,the user shall cnsurc that thccapacity of the hoisting equipment being used is notcxceeded.
5.15 Elevating Personnel
5.15.1 A rough terrain forklift truck shall not beused to lift people unless there is no other practicaloption. If a rough terrain forklift truck must be usedto lift people,the following precautions for the protec-tion of personnel shall be taken:
(a) provide a personnel platform which complieswith the design requirements listed in Part lll of thisStandard;
b) be certain that the platform is securely attachedto the lifting carriage and forks;
(c) be certain that the lifting carriage and forks aresecured to prevent them from pivoting upward;(d) on trucks equipped with rotators，deactivate therotation;
(e) provide protection for personnel in their normalworking position on the platform from moving partsof the rough terrain forklift truck that represents ahazard;
provide overhead protection as indicated to benecessary by the operating conditions;
(g) be certain that the lifting mechanism is operatingsmoothly throughout its cntirc lift range，both empty and loaded [as described in para. 5.15.1(t)],and thatall lift limiting devices and latches，if provided，arefunctional;
(h) be certain that the mast or boom travel is verti-cal — do not operate on a side slope unless the roughterrain forklift truck is leveled;
(i) be certain that the platform is horizontal andnever tilt platform forward or rearward when elevated;
(j) be certain that the rough terrain forklift truckhas a firm footing;
(k) be certain that required straining means such asrailings，chains，cable,body belt(s)with lanyard(s),etc.，are in place and properly used;
(l) place rough terrain forklift truck control(s) inneutral and set parking brake;
(m) before elevating personnel，area shall be markedto warn of work by elevated personnel;
(n) be certain that the path of platform travel is
clear of hazards,e.g., storage racks， scaffolds，overneaaobstructions,and electrical wires;
(o) keep hands and feet clear of controls other thanthose in use;
(p)lift and lower personnel smoothly，witn cauton,and only at their request;
(q) always lower the platform if you must move therough terrain forklift truck for adjustments in posi-tioning;
(r) alert elevated personnel before moving the plat-form. Then move the platform smoothly and withcaution.ASME B56.6 pdf download.ASME B56.6-2002 pdf free download
