Pipeline Accident Report. Atlanta Gas Light Company High-Pressure Gas Main Rupture, Atlanta, Georgia, December 1, 1977
At 1:00 p.m. e.s.t. on December 1, 1977, a 12-inch, cast-iron, high-pressure gas main owned by the Atlanta Gas Light Company was ruptured by an 8-inch, steel I-beam pile, which was driven through the pipe at a construction site in downtown Atlanta, Georgia. Within minutes, natural gas at 10-psig pressure migrated through the ground, entered sewer lines and electric conduit systems, and spread into nearby buildings. The gas did not ignite, but thousands of people were evacuated from nearby office buildings. A valve was closed at 2:45 p.m. to shut off the flow of gas to the ruptured main, and the area was declared safe at 4:00 p.m. The National Transportation Safety Board determines that the probable cause of the accident was the failure of the construction contractor to use information available to him on his blueprint which resulted in the rupture of the 12-inch, cast-iron, high-pressure gas main by the contractor's 8-inch, steel I-beam pile when it was driven through the pipe.
