PIPELINE ACCIDENT REPORT - ATLANTA GAS LIGHT COMPANY, ATLANTA, GEORGIA, AUGUST 31, 1972

The report describes and analyzes a gas explosion which occurred shortly after 9 a.m. on August 31, 1972 in the annex building of an Atlanta, Ga., high school. Gas had leaked into the building from a cracked cast-iron main located beneath the street in front of the building. Atlanta Gas Light Company (AGL) personnel arrived at the leak site approximately 1 hour after AGL was first notified of the leak and approximately 1/2 hour before the explosion. One person died and seven others were injured as a result of the accident. The National Transportation Safety Board determines that the probable cause of the explosion was the ignition of gas that leaked from a cast-iron main cracked by uneven soil settlement which applied a bending force to the pipe in an area weakened by graphitization. Contributing to the explosion was the failure by the gas company to check for gas in the building, to shut off the flow of leaking gas, and to notify police and fire officials.
