What should the driver do when using a stacker for cargo loading in a van or trailer?

The appropriate action when using a stacker for cargo loading in a van or trailer is to check that the ground where the truck or trailer is parked is safe. Ensuring a stable and safe surface is crucial because it helps prevent accidents that could lead to tipping over or losing control of the stacker while loading. An unstable surface can impact the balance and maneuverability of the stacker, increasing the risk of injury to the driver or damage to the cargo.

This practice emphasizes safety and efficiency in material handling by recognizing the importance of the working environment. Without a safe surface, all other efforts, such as stacking or loading quickly, may lead to hazardous situations.

Considering the other options, stacking cargo high can lead to instability and potential safety issues. Asking for assistance is valuable, but it does not address the immediate need for a safe operating environment. Loading quickly is not advisable when safety is at risk, as it may compromise proper loading techniques and awareness of surroundings.
