Synopsis: On March 24, 1972, in the Annandale section of Fairfax County, VA, a contractor's backhoe snagged a 2-inch steel gas main, and pulled the main out of a compression coupling 22 feet away. Gas company personnel arrived on the scene about 40 minutes later and started to search for the break. The gas was not shut off and the nearby houses were not checked for the presence of gas. A house, 240 feet away from the point at which the line was snagged, exploded. Two other houses exploded and burned. As a result of the accident, three persons died and one was injured; two houses were destroyed and a third was badly damaged; and $153,000 worth of property was damaged.
