Overfill is a major reason for industrial accidents. Since the Buncefield fire and explosion at the Buncefield UK oil storage facility on 11 December 2005, many organizations have updated or produced new standards based on information from the incident. In addition to overflow of hazardous fluids, overfill may encompass fluids that are safe to discharge to the atmospheric drains.
