PHILADELPHIA — Three people remain in critical condition after a gas main explosion that killed one utility worker and forced dozens from their homes in Philadelphia.
A spokeswoman says three patients are in critical condition in the Temple University Hospital burn unit Wednesday morning following the explosion in the city's Tacony neighborhood. Spokeswoman Rebecca Harmon says one other patient was treated and released.
Among the injured were four Philadelphia Gas Works employees and a firefighter. The Fire Department's communications center says the injured firefighter is in stable condition.
Firefighters battled the blaze for about three hours Tuesday evening. Crews from PGW had been dispatched to the scene to investigate reports of a gas odor when the blast occurred.
PGW says it's unclear what sparked the explosion.
