?On October 31, 2016, at 2:47 p.m., local time, while excavating, a contractor damaged the Colonial Pipeline Company�s (Colonial) 36-inch diameter refined liquid petroleum transmission pipeline, known as Line 1, near Helena, Alabama. The damage resulted in a release of gasoline from the pipeline, which ignited and burned for several days. Two excavation crew workers died, and four other workers were injured. The photographs in Figures 1 and 2 show the equipment and environmental damage that resulted from the fire. Figure 1 is a ground-level view of the ongoing fire and equipment damage that occurred from the gasoline release.
