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