- Abstract
- The National Bureau of Standards (NBS) was asked by the National Transportation Safety Board (NTSB) to conduct a field investigation at the site of the natural gas pipeline accident that occurred at the Canterbury Woods Subdivison, Annandale, Virginia, on March 24, 1972, as part of their overall investigation of the accident. The objective of the investigation was to determine how the natural gas entered the homes and to discover the path that the gas had followed from the leak to the homes. The basic approach used was to simulate natural gas flow underground by introducing a harmless mixture of air and refrigerant R-12 (tracer) in the vicinity of the underground gas leak, and then by checking for signs of the tracer within homes and other locations.
