The design of the structures that workers use to enter and exit utility trucks can affect the safety of workers.Workers can access the truck via the cab or via the truck bed on the side or rear. Large vehicles, such asaerial trucks in a utility fleet, can increase the risk of a slip or fall because of its taller height above theground. The authors conducted a study for EPRI (Electric Power Research Institute) that included measurementsof the steps and stairs of 29 electric fleet vehicles and a review of the standards related to structuresfor ingress and egress. The authors present design configurations of steps, stairs, and pullout laddersfor access to utility trucks from the cab, side, and rear. These examples include specific dimensions of theriser height and tread width, depth of stairs, and stair inclination angle. Design of access to the bucket of anaerial truck is not included. Ergonomists and vehicle designers can use the comparison table of standardsalong with the design examples to help them design ingress and egress structures for trucks that may reducethe risk of a slip or fall.
