I have reviewed several thousand incident reports for stand up lift trucks and they clearly show that operators can be ejected from end control stand up lift trucks during turns, collisions tipovers etc. Generally when something happens the oeprator will raise their foot off of the deadman pedal to brake. At that point they are standing upon one foot and hopefully have their hands on the steering tiller and the multifunction control. There have been many operators who have been severely injured due to their lifted leg coming outside of the compartment and many who have been off balanced enough that they go outside the compartment. Was there operator error? Maybe. Does that mean that the operator should have been injured? Definitely not. Ford is a company that utilizes rear doors on their stand up forklifts and they have foot and leg injuries because the door keeps the operators within the safer confines of the forklift. A latching rear door would also prevent the operator from being ejected if they become off balanced while standing on one foot.
