 NTSB Issues Preliminary Report for Natural Gas Explosion

The National Transportation Safety Board issued the preliminary report Friday for its investigation of the Feb. 23, 2018, fatal, natural gas-fueled, explosion in Dallas.

A 12-year-old girl was killed and four others injured in the residence explosion at 3534 Espanola Drive, Dallas. More than 300 residences were subsequently evacuated due to the nature and number of natural gas pipeline leaks discovered in the residential neighborhood.

The NTSB’s preliminary report notes the Feb. 23, explosion was preceded by two natural gas related events at 3527 and 3515 Durango Drive, Dallas, on Feb. 21 and 22, 2018. While all three events are natural gas related, the NTSB is investigating if the incidents are related to one another.  Multiple leaks were identified by Atmos, the natural gas service provider, during its assessment of the Durango Drive incidents. Numerous other leaks have since been identified throughout the neighborhood.

The report states the investigative team formed three technical investigative working groups that inspected the accident site, pressure tested pipe, collected records of the pipeline operations, pipeline integrity management program and emergency response and conducted interviews of Atmos and the Dallas Fire-Rescue Department personnel.

Information contained in the report is preliminary and subject to change as the investigation continues, and as such, no conclusions about probable cause should be drawn from the contents of the preliminary report.
