What is an important safety consideration when filling the loader bucket?

Preventing loose spoil from falling out when filling the loader bucket is a critical safety consideration. Loose material can pose risks to operators, bystanders, and other equipment on the job site. If spoil falls from the bucket while in transit or during loading, it can lead to accidents and injuries. Additionally, ensuring that materials are secure within the bucket helps maintain the load's balance and prevents it from shifting unexpectedly during operation.

While overloading the bucket may affect performance and stability, and underloading can compromise the efficiency of the operation, managing the integrity of the load—specifically, keeping spoil secure—directly addresses immediate safety concerns. Having a backup operator may be useful in certain situations but does not directly relate to the safety measures involved in filling the loader bucket.
