Abstract:

This report describes and analyzes a gas explosion and fire which occurred on June 23, 1973, in Bowie, Maryland. Gas had leaked from a crack in a plastic service line. Three persons died and a fourth was injured. The National Transportation Safety Board determines that the probable cause of the accident was the ignition of gas that had leaked from a stress crack in a plastic service line. The pipe had cracked because an occluded particle had created a stress point and weakened the pipe. Contributing to the accident was the lack of odor in the leaked gas when it reached the house and the atmosphere.

The report contains recommendations to the Office of Pipeline Safety of the Department of Transportation, the Department of Housing and Urban Development, the American Society of Mechanical Engineers of the Gas Piping Standards Committee, the American Gas Association, and the National Fire Protection Association. They concern leaking gas migration through soils and into buildings, odorant adsorption by soils, use of new materials in piping systems, odorant testing, and plastic pipe.
