What is one of the risks associated with using stackers?

The risk of collision with pedestrians is indeed a significant concern when using stackers. Since stackers are usually operated in areas where both operators and pedestrians share space, the visibility can be limited due to the height of the loads being lifted or the design of the equipment itself. Operators must remain vigilant and aware of their surroundings to avoid accidents, particularly in busy environments such as warehouses or distribution centers. This aspect emphasizes the importance of proper training, safety protocols, and the use of designated walkways to minimize the risk of collisions.

While other options address various logistical challenges, they do not directly relate to safety around people in the workplace. For instance, the inability to reach high places or unstable load positioning can certainly impact efficiency but does not pose the immediate risk of injury to pedestrians. Similarly, fuel consumption is typically a concern for operational costs rather than safety. Thus, the risk of collision with pedestrians stands out as a critical safety issue when using stackers.
