Crews Check for More Gas Leaks in Seattle, Wash.

September 29, 2011

Puget Sound Energy crews worked through the night checking for more natural gas leaks in the north Seattle neighborhood where a home exploded Monday and injured two residents.

Spokesman Roger Thompson says crews walked and drove a 5-square mile area using sensitive equipment that can detect methane.

Thompson says the leak that set off the blast was caused by corrosion initiated when a tree knocked down a power line Sunday and electricity traveled into pipes in the ground.

Two residents burned in the blast and fire are at Harborview Medical Center – a woman in serious condition and a man in satisfactory condition.

They were identified in The Seattle Times as 50-year-old Hong Phung, a Crista Ministries dietitian, and 53-year-old David Ingham, a Seattle City Light employee.
