What safety measure should be taken when loading or unloading a trailer?

Securing the trailer with chocks when not using spring brakes is a crucial safety measure because it helps prevent the trailer from rolling or shifting unexpectedly during the loading or unloading process. Chocks create a physical barrier that stabilizes the trailer, providing extra safety for workers who are handling cargo and reducing the risk of accidents that could lead to injury or damage to the equipment. This is particularly important on uneven surfaces or inclines.

While keeping the engine running might seem convenient for some operations, it can create hazards such as exhaust fumes or unintended vehicle movement. Loading from one side could potentially lead to imbalance and loading difficulties. Removing unnecessary cargo is good practice for efficiency but does not specifically address the safety of the trailer during the loading process. Hence, securing the trailer with chocks stands out as the best practice for ensuring safety and stability.
