GREENSBURG, Pa. (WPXI) – A firefighter was hurt early Saturday while battling a fire that badly damaged the Greensburg Public Works building. Flames broke out just after midnight at the building on South Urania Avenue in Greensburg. The firefighter was taken to the hospital. Their condition has not been released. The fire caused hundreds of thousands of dollars in damage, the fire chief said. The intense heat from the fire twisted the support beams inside the building. Two large dump trucks inside were badly charred. The city’s asphalt paver, snowplow equipment were also damaged by fire. The street sweeper machine may have been the source of the fire, the fire chief said.
