Which feature can help minimize the risk of leaks during oil deliveries?

A spill bucket is specifically designed to contain any oil that might escape during the delivery process, thereby minimizing the risk of leaks. Spill buckets are typically installed at the fill point of an oil tank and function as a catchment area to prevent any spills from contaminating the surrounding environment. By capturing any overflow or leakage during the filling process, the spill bucket plays a crucial role in maintaining both safety and environmental compliance.

While other features, such as shut-off valves, can be important for controlling the flow of oil and preventing overfilling, they do not specifically address the containment of accidental spills during delivery. Auxiliary tanks and larger delivery hoses relate more to storage capacity and flow rate rather than directly managing the risks associated with spills during delivery. Therefore, the spill bucket stands out as the most effective feature for leak prevention in the context of oil deliveries.
