What is the most common cause of minor spills of oil products?

Human error is recognized as the most common cause of minor spills of oil products. This can include mistakes made by personnel during operations, such as improper handling, insufficient training, or inadequate communication regarding safety procedures. Such errors occur in various contexts, ranging from refueling to maintaining equipment, illustrating the importance of proper training and adherence to protocols to minimize risks.

In contrast, equipment failure, while it can lead to spills, is less frequent compared to human error. Major casualties generally involve more severe incidents that are not typically classified as minor spills, and unforeseeable circumstances, while they can contribute to spills, are not as consistent a factor in everyday operations as human error. The prevalence of human error highlights the need for ongoing education and adherence to safety measures to prevent such incidents.
