| 摘要： | On June 9, 1994, a 2-inch-diameter steel gas service line that had been exposed during excavation separated at a compression coupling about 5 feet from the wall of a retirement home in Allentown, Pennsylvania. The escaping gas flowed underground, passed through opeanings in the building foundation, migrated to other floors, and exploded. The accident resulted in 1 fatality, 66 injuries, and more than $5 million in property damage. In its investigation of this accident, the Safety Board identified safety issues relating to pipline excavation damage prevention and rapid shut down of failed gas service lines. |
