What is the most common cause of spills during loading operations?

Overfilling due to human error is the most common cause of spills during loading operations as it directly relates to the actions of personnel responsible for monitoring and controlling the loading process. Human error can stem from a variety of factors, including a lack of attention, miscommunication, or inadequate training. This type of oversight can lead to a failure to stop the filling process at the appropriate level, resulting in spills that occur when the storage tank becomes too full and cannot accommodate the incoming product.

Improper monitoring of gauges or failure to follow established procedures are typical scenarios that can lead to overfilling. While other factors such as equipment failure, wear and tear, and adverse weather can also contribute to spills, they are generally less frequent compared to the risk posed by human error in active loading operations. The volume of liquid being transferred, combined with the complexities of managing that process, places significant responsibility on personnel, making human error a prevalent concern during loading activities.
