In 1907, 240 coal miners went to work at the Darr Mine in Van Meter, and only one came home. Nearly one century later, nine miners went to work in the Quecreek mine in Somerset County, and all nine were rescued.

The Darr Mine disaster in Westmoreland County and nearby mine accidents with high casualties in a short time frame spurred change in government regulations, reducing fatalities and enabling rescues like that of the Quecreek miners in 2002, said John Urosek.

  Last Friday, a natural gas pipeline exploded in Westmoreland County, just east of Pittsburgh. One man was hospitalized after his house went up in flames, while other nearby homes were damaged and residents were evacuated.

This week, armed security guards blocked off the site of the explosion, as federal pipeline investigators worked with the owner of the pipeline and state officials to determine the cause of the blast.

The underground pipeline, which is owned by Spectra Energy, carries natural gas from the Gulf Coast to the northeastern U.S. It was built in 1981.

Company officials shut off the pipeline, but not before the fire burned an area nearby in Salem Township.
