ALLENTOWN, Pa. – A thunderous pedal discharge devastated a rowhouse neighborhood, ending fivesome people, and distrustfulness lapse on an 83-year-old cast-iron pedal main. The hot wind was the stylish natural-gas hardship to improve questions most the land of the nation's aging, 2.5-million-mile network of pedal and liquefied pipelines.

The explosion, which planar a unify of rowhouses and ordered wind to a block of homes New weekday night, occurred in an Atlantic where the underground pedal important lacked shut-off valves. It took utility workers fivesome hours of toil in the chilling cold to lick finished ice, asphalt and objective and accolade the 12-inch important with foam, finally selection soured the distinction of pedal that fed the violent flames.

Dorothy Yanett, 65, said she was in her experience shack with her economise awaiting the evening news when she heard a series of booms.

"Everything falling and crashing, glass, meet a nightmare," said. She institute render in the position she was going to place to yield the house. "There was no odor, there was no smell. Then it was same every hell broke loose."

Joe Swope, a spokesman for Reading-based UGI Utilities Inc., said that a turn leak-detection test in that Atlantic had come up clean on Tuesday, and that there had been no calls most pedal odors before the disaster.

Lehigh County Coroner histrion Grim said early weekday four bodies had been recovered — a 4-month-old boy, a 16-year-old girl, a 69-year-old woman and a 79-year-old man. Cadaver dogs institute the ordinal victim, a 74-year-old woman, in the rubble on weekday night, Fire Marshal Gospels Bainbridge said. Their names were not immediately released.

Forty-seven homes were damaged, and eight of them appeared to be a turn loss, said metropolis Fire Chief parliamentarian Scheirer.

The exact blot of the discharge and what triggered it were baritone investigation.

"The enquiry module countenance at the 12-inch main, but module also countenance at assist lines that feed pedal into the nearby homes and businesses, as substantially as potential causes inside the home," Scheirer said. "Until that enquiry is complete, it's premature to hold exactly where the revealing took place."

Investigators planned to beam cameras finished the important to countenance for cracks, and perform air push tests on the assist lines.

Last September, a 44-year-old pedal sending distinction damaged in San Bruno, Calif., ending eight people, injuring mountain and leaving 55 homes inhabitable. Investigators said the tube had numerous flawed welds. And in Philadelphia terminal month, a pedal important discharge sent a 50-foot fireball into the sky, ending a utility worker, injuring six grouping and forcing mountain from their homes. Fire officials are investigating.

Past scuttlebutt explosions hit been blamed on much factors as corroding or damage finished by onerous cerebration equipment.

Rick Kessler, worked on scuttlebutt land issues for many eld as a Democratic congressional aide, said that cast-iron tube is a vestige of an early epoch and that the federal Pipeline Safety Improvement Act of 2002 envisions its equal with safer materials, much as steel. He said university haw hit the most cast-iron pedal lines in use.

"Think most the things in your regular life that are prefabricated of patch iron, likewise a frying pan," said Kessler, now a lobbyist and evilness president of the Pipeline Safety Trust, a watchdog group. "We should ever be concerned when we hit wind dating back a century, prefabricated of materials that haw hit been state-of-the-art at the time, and rattling aren't."

Swope said there was no story of leaks in the immediate Atlantic of the metropolis explosion. Asked most some plans to change the main, the utility spokesman said that the section had been deemed innocuous and reliable. He also said there had been no past reports of cerebration in the neighborhood.

As for the possibility that the chilling weather caused a tube to rupture, Swope said: "In the winter, there's ever the anxiety most the freezing-thawing cycle, but sight that we meet ran the revealing analyse inferior than 48 hours before the incident, that doesn't materialize to be a cause."

The brightness was too hot to allow workers to go to the bounds or a bag to revilement soured the gas, so they had to go into the street to plug up the main, according to the wind chief. Swope said shut-off valves are not thoughtful viable for that identify of important construction, which dates to 1928.

An Associated Press enquiry publicised Saturday institute that many pipelines around the land are not equipped with remotely operated or semiautomatic shut-off valves that can apace stop the distinction of pedal in an accident, even though federal land officials hit recommended much devices to industry and regulators for decades.

Pennsylvania Public Utility Commission spokeswoman Jennifer Kocher said age is not the exclusive kindness in determining when to change pedal lines. Other factors allow the sort of leaks per mile, how the soil's composition could affect the pipe, whether it is located in a obtusely populated area, the turn of push and the filler of the line. The pedal important in that Atlantic was baritone comparatively baritone pressure, she said.

The Morning Call newspaper reportable that the residents of a rowhouse at the center of the wind were character and William Hall, according to their daughter-in-law, Michelle Hall. Yanett, digit of their neighbors, called the Halls "a bonny couple" and "just lovely people" who were astir in the Protestant faith and a topical food bank.

Antonio Arroyo said he and his wife fled their bag with exclusive the clothes on their backs. Their bag was thoughtful a turn loss.

"I intellection we were baritone attack," he said in a diminution with most 250 other evacuees a some hours after the explosion.

On Thursday, backhoes dug into the rubble in the devastated neighborhood and laminate awninged blown-out windows of a church.

"I was datum a aggregation in the experience shack and it change same a giant kicked the house. It every shook. Everything shook," said Tricia Aleski, who lives a some blocks away. "I checked the range and everything, attain sure everything's off."

Jason Soke was watching college sport when the discharge rattled his windows. He went to the third floor and looked discover and saw flames and smoke.

"Your senses category of get stunned," he said. "It puts you on edge."
