Which of the following is wrong to prevent stacker disasters?

The correct choice highlights an important safety principle related to forklift operations. Asking an assistant to stand next to the driver's seat is professionally unadvised because it creates a hazardous situation. The driver's attention can easily be diverted, leading to potential accidents. Additionally, the close proximity of another person to the operations can increase the risk of injury if the stacker or forklift should move unexpectedly or if there is a loss of control. Operators should be mindful of their surroundings and avoid placing others in danger by ensuring that all personnel remain at a safe distance from the operating equipment.

In contrast, the other options are all valid practices that contribute to safe stacker operation. Regular inspections of equipment ensure that any mechanical failures are identified and rectified before they can lead to accidents. The use of safety barriers is essential for creating safe zones around areas where forklifts operate, thereby minimizing the risk of contact with bystanders. Maintaining clear communication is crucial in a busy work environment, as it helps coordinate actions and ensures that everyone is aware of the status of the equipment and potential hazards. Each of these practices forms a critical part of a comprehensive safety strategy in warehouse and forklift operations.
